Implementation of Collaborative e-Supply Chain Initiatives: An Initial Challenging and Final Success Case from Grocery Retailing Abstract We discuss the challenges of implementing an Internet-based platform for creating collaborative supply chains using a case study in the retail sector. The case presents how an Internet-based collaboration platform was implemented to address the strategic issue of increasing shelf availability and customer service in grocery retailing, an issue that has emerged as one of the major confrontations for the whole sector over the last years. The case presented shows the challenges of executing such strategic collaborative supply chain initiatives which, although arguably beneficial, can be hindered by IT adoption failures. A longitudinal view of the case is presented, from an initial pilot back in 2001 to the final success in 2005. We discuss the particular challenges of the execution of Internet-enabled collaborative supply chain initiatives as well as possible managerial actions through a simple framework we develop based on the lessons from the case. Keywords: supply chain collaboration, store ordering systems, business-to-business, e-business platform, IT implementation, inter-organisational systems, CPFR MOTIVATION FOR AND INTRODUCTION TO THE STUDY The advent of e-business has created several challenges and opportunities in the supply chain environment. The Internet has made it easier to share information among supply chain partners and the current trend is to try to leverage the benefits obtained through information sharing (also called visibility) across the supply chain to improve operational performance, customer service, and solution development (Swaminathan and Tayur, 2003). Following this trend, core business processes may need to be rethought and redesigned, new organisational forms and inter-organisational structures may need to be developed, and the emphasis shifts towards collaboration rather than competition (Hackney et al., 2004). In grocery retailing and the Fast Moving Consumer Goods (FMCG) sector, this collaboration aspect has been expressed through the Efficient Consumer Response (ECR) movement. ECR encompasses multiple technological and managerial innovations which aim to transform retailers, distributors and manufacturers into more efficient and interlinked organisations placing special emphasis on collaboration (JIPOECR, 1995). One of the first forms of supply chain collaboration has been the practice of Vendor Managed Inventory (VMI) or Continuous Replenishment Program (CRP), as it is often called in the context of grocery retailing, where the buyer shares demand information with the supplier who, in turn, manages the buyer’s inventory. The practice of Collaborative Planning Forecasting and Replenishment (CPFR) has extended this collaboration to include the exchange of forecasts based on widely shared information (usually point-of-sales (POS) data and promotion plans), having a more strategic focus and placing more emphasis on the demand side. More specifically, the VMI/ CRP practice has been implemented at the level of the retailer’s central warehouse, based on the daily sharing of the warehouse inventory report data and orders information. Most CPFR initiatives also focus on the central warehouse rather than on store replenishment, and deal mainly with mid/long-term replenishment planning for promotion items and new product introductions. The VMI/ CRP practice has been extensively studied by researchers but mainly from the perspective of evaluating the impact of information sharing on supply chain performance rather than from the IT implementation perspective. Furthermore, studies on CPFR mainly define it as a new practice and discuss its adoption or evaluate its business impact. To better understand the technology adoption challenges of such initiatives, we analyze a case of implementing a web platform enabling information sharing and collaboration between retailers (Veropoulos Spar, a €770 million major Greek retailer) and suppliers (i.e. Procter & Gamble, Unilever, and Elgeka) to support the store-replenishment process. Contrary to the VMI/CRP practice and prior CPFR initiatives, the focus of this case is on store rather on central-warehouse replenishment, addressing the daily ordering process with the objective to maintain optimum levels of stock in the store and avoid “out-of-shelf” (OOS) situations. The problem of OOS is a critical issue for both suppliers and retailers today, as low OOS levels have been positively related to increased consumer value, higher consumer loyalty to the brand and shopper loyalty to the store, increased sales and higher category profitability (Campo et al., 2000). The main focus of the case is to illustrate that realizing the promises of Internet-enabled collaborative supply chains requires something more than just high-level strategic planning; it also demands the successful implementation of the enabling IT systems. Through the case we discuss the particular challenges of the implementation of collaborative supply chain initiatives using Internet technologies, and suggest possible managerial actions based on the lessons from the case. The case has a number of other interesting aspects: it entails an innovative retailer-supplier collaborative business process in a many-to-many environment; it represents a technical challenge: employing an e-business platform to support critical operations requiring vast data exchange and synchronization on a daily basis between various information systems; it addresses a problem that is currently considered as one of the major issues faced by companies in the FMCG sector, that of shelf availability; it shows the extra challenges of such collaborative initiatives due to the need for coordination among a number of organisations; it shows that collaborative supply chain IT systems can be -executed only after the in-house business processes and systems are reorganised and stabilized: companies need to consider Internet-enabled outward looking processes only after preparing their in-house processes and IT systems. In the following section we describe the case context in more detail, covering the company background and the process of collaborative store ordering. In section three the course of implementing the web-based collaboration platform in the specific context is presented, from the initial pilot to the fallout phase and final reincarnation of the project. In section four the lessons from this case as well as the relevant problems and propositions are discussed. We conclude in section five with discussion and suggestions for further research. THE CASE CONTEXT Company background In the competitive business environment of the Greek retail-grocery market, where two international and three national retail chains account for approximately 60% of the total retail market, Veropoulos is ranked in fourth place with about 9% market share. With 196 stores around Greece, Veropoulos covers almost the whole country, with sales estimated at around 770 million Euros for the year 2005. Recent expansion outside Greece has added 9 new large stores in the Balkan area. The company has an organisational structure with three main arms: commercial, logistics, and financial. Nick Veropoulos, CEO and son of one of the two brothers that founded the company, is open to new ideas and a great supporter of ECR global industry activities, participating in both local and European ECR groups. Since 2001 Veropoulos has been the first and only supermarket chain in Greece offering Internet online-store services to its customers. In terms of product distribution, the company owns a central warehouse serving all the supermarkets around the country with its own fleet of vans. Almost 50% of the products in large stores are replenished through the central warehouse, whereas for the smaller stores the percentage of centralisation is around 60-70%. The remaining is replenished directly to the stores by the non-centralised suppliers. In Spring 2001, Veropoulos suffered an average out-of-shelf (OOS) rate of 8.4%, which can be translated into a yearly turnover loss of more than 20 million Euros, leaving aside the negative impact on shopper loyalty and long-term profitability. More than 70% of these situations were attributed to mistakes and omissions in the store ordering process. Clearly, these numbers indicated that there was a need to improve store ordering and replenishment practices in use at that time. Nick Veropoulos was convinced that “even a small reduction in out-of-shelf can bring significant results in turnover increase and improved consumer satisfaction; … clearly this is not a problem we can ignore and the suppliers have to get involved as well; it’s not only ours but also their problem”. Collaborative store ordering A typical grocery retail store (supermarket) has more than 10.000 products in its assortment. Deciding what to order every day at the store level is, naturally, a daunting task. Currently, the store ordering and replenishment process is a combination of direct-store-delivery (DSD), where the respective product suppliers are those preparing the order (i.e. the list of what needs to be supplied to the store) and delivering their products directly to the store, and centralized-delivery, where the responsible store personnel prepare and send the order to a central warehouse, which in turn delivers the products of several suppliers to the store. Traditionally, various IT systems have supported these processes. Ogawa (2002) distinguishes between three different types of systems used to support store ordering to the central warehouse. These range from simple replenishment-ordering systems, merely supporting the typing or hand-scanning and electronic transmission of the order, to automated-ordering and hypothesistesting ordering systems, relying on decision support tools using sales data and other information in order to prepare the order, which is either automatically sent or first proposed to and confirmed by a user. In the case of direct-store-deliveries, supplier salesmen may use hand-held devices (e.g. PDA’s) to type-in the order and send it electronically over mobile networks while still being in the field. This type of system doesn’t provide any decision support, but in some cases past order data may be used to facilitate the order decision making. The employment of such systems by both retailers and suppliers in the store ordering process has had a positive effect on process efficiency, but has not been proved sufficient to address the out-of-shelf problem, as reported in several studies (Gruen et al., 2002; Roland Berger, 2003). A reason for this can probably be sought in the difficulty to correctly estimate consumer demand in such a complex environment and the limited information that is available to either retailers or suppliers when working independently to prepare a store replenishment order. In their attempt to address the problem, retailers and suppliers have turned, during the last decade, towards collaborative replenishment practices, such as CRP/VMI and CPFR. CPR/VMI has been employed to support the daily ordering process at the level of the retailer’s central warehouse, rendering the product supplier responsible for the demand forecasting and order preparation. In order to do so, the supplier receives the inventory report (in the form of an EDI message) from the retailer’s central warehouse on a daily basis and prepares a suggested order. This may require confirmation by the retailer (in which case the process is called CMI, for Co-Managed Inventory) or not (thus called VMI). CRP moves one step ahead of VMI and reveals demand from the retailers’ stores. The inventory policy is then based on the sales forecast, built from historical demand data and no longer purely based on the variations of inventory levels at the customers’ main stock-holding facility. CPFR can be seen as an evolution from VMI and CRP. It addresses not only replenishment but also joint demand forecasting and promotions planning, focusing on promotions and special-line items. CPFR is based on extended information sharing between retailer and supplier, including point-of-sales (POS) data, forecasts and promotion plans. Based on these short descriptions, VMI and CRP are more about efficient replenishment and supply, whereas CPFR puts more emphasis on the demand side. Combining the characteristics of conventional store ordering systems with information-sharing and collaboration capabilities and applying the notions of CRP/VMI and CPFR at daily store level define new collaborative store ordering processes. The following description illustrates how a web-platform can be used to support collaborative store ordering for both DSD and central warehouse ordering. The central web platform is updated daily with store-level information, including point-of-sales (POS) data, delivery quantities, product assortment, promotion activities, new product codes etc. Most of these data come from the retailer’s central information system (e.g. product assortment, product catalogues) and directly or indirectly from the store information system (e.g. POS data), but some information may also come from the central warehouse or the suppliers’ information systems. Based on this information, the system running on the central web platform prepares respective order proposals per individual store. For centralized deliveries, the store personnel review the respective order proposal and, upon confirmation, the order is sent to the retailer’s central warehouse. For direct-store-delivery, the supplier salesman first reviews the system’s order proposal, which is then sent to the store for final confirmation and then to the supplier for execution. Both the stores and the suppliers’ salesmen access the system through the web. This is schematically depicted in Figure 1. <<Insert Figure 1 here>> EMPLOYING AN E-BUSINESS PLATFORM FOR COLLABORATIVE STORE REPLENISHMENT The initial pilot In the context described above, and with the objective of addressing the stockout problems, the promising capabilities of a web platform supporting collaborative store ordering were presented to the top management of Veropoulos by a software service provider, a start up called OniaNet, in the spring of 2001. OniaNet was a new company acting as an intermediary between supermarkets and their suppliers, supporting their business transactions and exchange of information via its electronic marketplace as an Application Service Provider (ASP). The positive attitude of Nick Veropoulos, the CEO, towards ECR-related supply-chain initiatives, the presentation of the value proposition by OniaNet, and the full support of a key and trusted supplier (Elgeka) who was also an investor in OniaNet, spurred enthusiasm to Nick for such a project and triggered the decision of Veropoulos to pilot test such a system in the spring of 2001. Suppliers were invited to view this as a unique opportunity to have direct access to daily store sales data (POS data), a possibility which apart from supporting the store replenishment process would enable them to monitor promotion activities and new product launches, identify missed sales opportunities, etc. Three suppliers agreed to participate in the pilot project. Elgeka, a domestic company with an international clientele, Procter & Gamble, and Unilever. Elgeka is a direct-store-delivery supplier operating their own logistics fleet. They were also shareholders of OniaNet, the software service provider. P&G and Unilever, on the other hand, delivered to the stores through Veropoulos’ central warehouse. Moreover, five representative stores were selected to participate in the pilot program. The pilot went live on October 1st, 2001 and ran in the five pilot stores for six weeks, from the 1st week of October to the 2nd week of November 2001. At this stage the five pilot stores used the Internetbased platform for their collaboration with the direct-delivery-supplier Elgeka, and for ordering the products of the two centralised suppliers, P&G and Unilever, from Veropoulos’ central warehouse. For the rest of the centralised products they followed the traditional processes. Moreover, for the remaining suppliers the processes were unchanged. The evaluation of the pilot, based on systematic out-of-shelf and stock measurements, returned business results that were well above expectations soon after the implementation of the pilot: in a sixweek period, the OOS reduced by 62% in the pilot stores but only by 23% in five control stores i. In addition, the OOS attributed to the two main reasons, wrong order quantity and no-order at all, showed an even higher decrease in the pilot stores (see Figure 2). At the same time, the inventory measurements showed that the OOS reduction was not due to any inventory increase. However, leaving aside the positive business results, an important lesson from the pilot was that the system could not operate only for few of the suppliers as this meant that the store employees would have to deal with four different processes just for ordering: ordering to the central warehouse and ordering for direct-store-delivery both in the traditional and the new way. Thus, at this point the objectives of the project changed to include the upgrade of the system to support the orderings to the central warehouse for all the centralised products – hence all internal to the organisation ordering – covering over 6.000 products from about 600 products during the pilot. Moreover, “intelligence” for making order recommendations to simplify the ordering task of the employees was to be added at this stage. This was very challenging from a technical perspective. These requirements also had to be met in a very narrow time window of about three months, as set out by the service provider, who was under funding pressure. It was at this time that the objective of using the ebusiness platform, therefore, shifted focus from enabling strategic supplier-retailer collaboration to supporting critical within-company operations, mainly the store-ordering process to the central warehouse. <<Insert Figure 2 here>> The failure of the roll-out Influenced by the relatively positive early business results and by the time pressure of the service provider OniaNet, the top management of Veropoulos decided to roll out the system to the rest of the stores and sign a three years contract with OniaNet. After an initial roll-out phase to 20 stores and further work on the system for the next three months, the roll-out continued with the rest of the stores till November 2002. Unfortunately, users were not very happy with the new technology as their Internet connections were slow and the web interface seemed too complicated to them. Once all the stores were online the situation got worst, as users started experiencing even more system delays and their frustration with the new technology increased. Many problems arose also from information quality issues, resulting in the system proposing wrong products to be ordered or not including in the order proposal others that should be ordered. This further undermined the users’ trust in the system and the quality of the order proposal. During this time, the service provider worked intensively for over three months to overcome the various information-quality issues while the system was in use. More important, it turned out that the actual users in the stores were poorly trained: in fact, although initially the store managers were originally intended to be prime system users (to enable them to evaluate the information and place orders), eventually the store managers “pushed” the system use to other store personnel. These “unplanned actual users”, however, were not appropriately trained to use the new system. On the suppliers’ side the situation was also mixed. For Elgeka the story was more positive. Apart from being a shareholder in OniaNet, Elgeka as a direct supplier had the human resources to invest in the new system and process and was enjoying benefits that it didn’t have with the traditional process, such as access to the daily POS information, possibility to order from a distance, etc. With a single salesman, Elgeka was managing orders for 20 of the Veropoulos stores through the collaboration platform. However, for the centralised suppliers the new process was bringing about major organisational changes, as it required reinvestment in human resources. For example, Unilever as a centralized supplier had laid the responsibility for the whole Veropoulos account to just one sales-person visiting the central warehouse. If the company were to implement the new process, a lot more sales effort would be required to prepare suggested orders for the many retail stores on a daily basis. As the two centralized suppliers were not prepared to undergo these organizational changes just for one of their retail customers, they abandoned the initiative immediately after the pilot. However, they continued to send their product catalogue electronically to the web platform, in order to support Veropoulos in maintaining proper product information and run the store-ordering process internally. Apart from the initial three suppliers, the participation of other suppliers was very limited, as both the problems that the Veropoulos stores were facing with their internal ordering and the anticipated organisational changes were raising serious concerns to them too. In early 2003, OniaNet, due to financial problems attributed to the suppliers’ limited participation to a great extent, had to stop operations. Nick Veropoulos was caught by surprise. However, most of the people in the stores however felt happy they would return to the old familiar system and process. The reincarnation phase From the ashes of OniaNet a new service provider, having some key personnel from the old OniaNet team, decided to invest in the OniaNet business model in the summer of 2003. The new company, Retail@Link, approached again Veropoulos to recommend a resurrection of the ambitious collaborative ordering initiative. The argument was that, first, the benefits of such a system are clear if they succeeded in implementing it, and second, this time around they knew much more about how to succeed as they had already done a lot of their “homework”. The dilemma for Veropoulos was smaller than initially appeared: if they didn’t continue they would have to go back to the previous situation; if they continued they had a good chance to achieve the promising business results this time, provided the lessons from the previous attempt were taken into account. Moreover, the internal IT department was not in the position to take this as a new project aboard, so the only alternative still remained with a service provider. However, the approach to be followed needed to be different this time, especially as far as the participation of suppliers was concerned. The Veropoulos management were convinced that they should first make the system support the internal ordering process efficiently before any attempt was made to open it up to supplier collaboration. This is in line with evidence provided from other industries and cases (e.g. what is considered to be a best practice internet-enabled business model of Cisco (Nolan, 2001)), suggesting that companies need first to rationalize and web-enable their internal systems and processes before implementing internet enabled collaborative processes and systems. In September 2003, Retail@Link was given the green light to pilot test the system, for a second time, in five Veropoulos stores to support orders to the company’s central warehouse only. The implementation approach was quite different this time. Instead of customizing an existing e-business platform to the needs of the specific case, which was the approach OniaNet had followed in the past, the new service provider built the system from scratch, based on the user requirements that had been collected during the previous phase from the actual users this time, store managers and personnel, while the technical requirements were focused around scalability, efficient and robust data loading processes, and fast system response – key technical requirements that hurt the usage of the system during the first attempt. In addition, many data-validation checks were implemented to ensure high quality of information and reliable order proposals. The new system was pilot tested for more than three months, with the service provider working hard to sort out any issue, even a minor one, that would cause frustration to the end users. Scalability of the system was ensured by operating the platform for all the stores from the very beginning, even though only five stores were actually using it at this stage. With the old system as a benchmark, the new system was exceeding by far the pilot users expectations this time. Their positive attitude soon spread around, creating a positive anticipation among the rest of the stores. After the system had operated for a full month with no error incident and user complaint, Veropoulos management, being more cautious this time, took the decision to expand the system to the whole chain. Expansion went fast, as the system was centrally hosted and no installations at store level were required. After about two months, 160 Veropoulos stores were online, utilizing the Internet platform to place orders to the central warehouse. After a year of successful operation, and after becoming convinced that the new system was internally successful and was there to stay, Veropoulos decided to open up the system, as originally planned in 2001, to supplier participation. Schwarzkopf&Rilken was the first direct-store-delivery supplier to join in 2005. This time the inclusion of suppliers showed many signs of success. For example, Schwarzkopf&Rilken reported a 64% sales increase in the pilot stores for its products compared to a 3% increase in the total Veropoulos stores and started rolling-out the system to the rest of the stores. Other suppliers started piloting as well, mainly centralized ones wishing to get access to store sales data. <<Insert Table 1 here>> DISCUSSION: CHALLENGES AND LESSONS LEARNED In this section we identify the main challenges encountered and discuss some of the lessons from the case. We group the challenges of execution in three main categories: technical challenges, organisational challenges, and multi-party coordination challenges (see the framework in Figure 3). Table 1 also summarizes the main points that were done differently, regarding these challenges, the second time relative to the first one, which turned this case from an initial failure to a final success. The objective of this discussion is to illustrate that realizing the promises of Internet-enabled collaborative supply chains does not just require high level strategic planning and top-management commitment, but also the successful implementation of the enabling IT systems, addressing technical, organisational and coordination issues in a many-to-many environment. Other dimensions, pertaining to the translation and power perspectives of different actors, as discussed in the last part of this section, need also be considered. <<Insert Figure 3 here>> Technical challenges First of all, the case exposes some important yet often disregarded “technical” principles which should characterize any information system development and which are especially important in supporting supply-chain integration: 1. Efficient data management and validation mechanisms are crucial to ensure information quality which in turn is crucial for instilling trust in people towards any decision support system. 2. System user friendliness, ease of use, and speed of response are important determinants of user satisfaction and system acceptance. 3. For large IT systems connecting many other systems (possibly from many organisations), the points of possible failures increase exponentially (why exponentially? Don’t they increases more-or-less linearly as the number of suppliers involved increases?, requiring extra technical and management care before broader roll out. If these principles had been respected, many technical and usage (“on the ground”) problems with the system could have been avoided the first time. However, the technical challenges of setting up this collaboration platform for the first time were, as always, too many and possibly disorientated people from these basic principles. The technical challenges, stemming from the three key principles outlined above, are mainly related to the following: 1. Data-integrity and synchronization issues: Roland Burger (2003) identifies data accuracy and synchronization as one of the top five challenges the grocery sector faces today in the attempt to streamline the supply chain. Although the sector has adopted barcoding technology as a standard to identify products, yet the information is maintained at different levels in either the retailers’ or the suppliers’ systems causing serious integrity issues when data synchronization is required. In order to overcome these issues, several data-validation and integrity-checking rules had to be built into the final system so that information quality problems didn’t confuse the end-users and undermine the order proposals’ reliability. 2. Quality of the automated inter-organisational system links. Many of the data-quality problems resulted from errors and mistakes in the file-transfer process and exchange of data files between the retailer’s systems and the collaboration platform. The use of FTP, which was the initial approach, was not adequate to meet the requirements of such a demanding data environment both in terms of reliable and secure file transfer. In the second approach, the technology of web-services (Ferris and Farrell, 2003) was used instead to support the exchange of data files. Here, several control mechanisms were implemented to ensure reliable and secure information exchange. The data-loading processes were also enhanced to become more robust to data failures and send e-mail and/or SMS notifications in case of critical errors. 3. Web user-interface combined with slow Internet connections. One of the most technically challenging issues was to enable efficient decision support for the ordering of about 1,000 products (which was the average size of an order proposal) over a dial-up Internet connection of 56Kbps at best. The challenge involved deciding both what information to display to the user in order to enable the right ordering decision, but also selecting the right functionality to allow for fast browsing and order update. What was causing a lot of frustration to the users with the initial OniaNet system was the idle time they had to spent in front of a PC just waiting for web-pages to download (in some cases this was more than half an hour in total for updating a single order). With the new system, the users make a print-out of the order proposal, consult it when physically checking the store and then type-in the final order in much the same way they did before the OniaNet system but just faster. Further improvement of the system is currently sought towards the direction of loading the order proposal on a hand-held device, enabling the user to update the order simultaneously with the physical shelf check. 4. Scalability of the centralised software architecture. Skuff and St. Louis (2001) have analyzed the benefits of centralisation vs. decentralisation of application software. In our case, the centralised software architecture, imposed by the central web collaboration platform model, led to serious scalability issues initially. When all the 260 stores were using the OniaNet platform for their ordering to the central warehouse, the users started experiencing serious delays in the system response. However, the scalability problem dissolved after (a) the system’s database was redesigned, and (b) new functionality was provided for order-update which resulted in limited user interaction with the system. Table 2 summarizes the advantages and disadvantages of centralised vs. decentralised software architecture to support collaborative store ordering. A variation of the centralised model, enabled e.g. by the use of web-services technology, allows that part of the processing (e.g. what requires extensive user interaction, such as the order update) to take place in the store, while the gathering of the information, the management of the order proposal criteria etc. continues to take place centrally. This hybrid approach combines the benefits of both models, but the respective technology is not fully implemented and tested yet. <<Insert Table 2 here>> 5. Controlling the various points of system failure. Last but not least is the technical challenge of controlling the plethora of points of failure in such a complex system. In addition to controlling hardware and software failures of the main platform (web servers, application servers, data-base servers, dataloading processes etc.), many new points-of failure are added, most of which relate to the e-business characteristics and inter-organisational nature of this environment. These range from Internet connectivity issues in the stores to back-end integration and file-transfer issues between the central platform and the various information systems, to hardware printer failures in the stores, etc. No matter what reason applies, in the eyes of the end-user any of these failures results in either system unavailability or information flaws, translated further into inability to carry out the critical business process of store ordering. Therefore, any such system should be equipped with various failure control mechanisms and should be iteratively and rigorously tested (and pilot tested before broader, possibly phased, roll out) in order to eliminate or minimize such a possibility. Organisational challenges This case is clearly a demonstration of technochange, defined by Markus (2004) as situations where IT is used in ways that trigger major organisational changes. Hence, unavoidably the success of such systems and the strategic initiatives they support relies on the careful management of change in the organisation (Kallio et al., 1999). The contrast between the initial failure and later success provides lessons on the challenges of such a technochange. These challenges can be seen at various levels: user involvement, communication, and technology/business alignment and business process redesign. We consider these next: 1. User involvement challenges. To begin with, the case provides a vivid example of the difficulty of even sometimes defining in large organisations “who the actual users of the new system will be”. During the first attempt, the company’s management team assumed the actual users would be the store managers. However, over time it became clear that, largely due to the difficulties in using the new system (which also shows how all challenges are inter-twined in complex ways) the managers “pushed” the usage of the system to other store personnel. It is often the situation that the final users of new technologies are a broader (or even different) group than the one initially considered, and this case clearly shows the degree of this challenge. Moreover, a main difference between the two attempts was the more careful definition of requirements – given also the experience from the initial failure – in collaboration with the users during the second attempt. Finally, training is a fundamental part of any large IT implementation often overlooked. The initial difficulties in the early attempt show the dangers of poor training of the actual users. 2. Top-down and bottom-up communication. Despite the positive business results from the very beginning, many end users were resisting the introduction of the new system – probably due to usage difficulties and unclear vision of the value of the system. For example, there is anecdotal evidence that during a company-wide event in 2002 some store managers “requested the withdrawal of the new system”. Some users were also under the impression that the system will finally “fail” and hence be withdrawn. Such phenomena emphasize a key success factor of such implementations: heavy top-down communication of the value of the new system and of its final persistence. At the same time, bottom-up communication is also valuable. While initially some of the negative comments of the users were disregarded, in the second attempt all users’ comments (i.e. complaints from the initial pilot) and perceptions of the new system were very carefully gathered and taken into consideration. 3. Technology/ business alignment and business process redesign. A fundamental principle in information systems implementation is the very delicate balance between building the system according to user requirements and changing the users’ work practices to conform to specific system dictates (Butler and Fitzgerald, 1993), such as those posed by a pre-defined e-business platform. Some of the key decisions of large implementations are answers to the question “should we change the system or should we change the business practices”. The case also shows the challenges of managing the complexity of business processes with the introduction of new technologies. For example, during the first attempt it became clear that the introduction of two new processes (order processes via the new system from the central warehouse as well as from the direct suppliers) increased the overall complexity of the order processes: there were now four different processes instead of two. It therefore became crucial to redesign the business processes by effectively eliminating the old ones from the central warehouse. As clearly noted in the past, business process re-engineering – effectively involved during large IT implementations – is not only about “automating business processes” but also about “obliterating” them (Hammer, 1990) Multi-Party coordination challenges E-business initiatives across companies, such as the e-supply chain one considered here, have a whole new set of challenges, compared to within-company large IT implementations, due to the involvement of many independent organisations. The case shows clearly the challenges of such e-supply chain initiatives that arise from the need for coordinating many parties “outside the boundaries of the firm”. Some of the challenges arise from the nature of the Application Service Provider business model, and of emarketplaces in general, while others arise from the coordination between the retailer and the suppliers. The challenges of the Application-Service-Provider model According to the Application Service Provider (ASP) model, ASPs offer and manage outsourced application services to many organisations via the Internet, while organisations outsource applications to ASPs to reduce upgrade and maintenance costs and to focus their efforts on core competencies (Soliman et al., 2003). The appeals of ASPs are the per-user pricing models, one-to-many access possibilities to applications, IT expertise and capabilities, and value-added management services (Kern et al., 2002). What Veropoulos learned from the first experience was that before deciding to use the services of an ASP, the financial viability and long-term commitment of the provider need to be ensured, especially when the switching costs are high. Kern et al. (2002) argue that although the ASP model offers an electronic outsourcing solution, there are in fact many similarities with more traditional IT outsourcing. Soliman et al. (2003) also mention additional issues that need to be addressed by a retailer when examining the use of the ASP model for supporting the store ordering process, such as reliability, service level etc. Given the many points of system failure as discussed above and the high dependence of the store-ordering process on information quality, the definition and guarantee of a clear service level is quite difficult in the case discussed. Furthermore, because of the extent of information provided by the retailer’s information system and loaded on the collaboration platform, a retailer may feel uncomfortable to provide all this information to a third party and lose control over it. From informal discussions with all major Greek retailers, it it clear that many of them feel concerned about having a big portion of their internal data hosted on the platform of an ASP. At the same time, some global retailers such as Wal-Mart, Metro and Tesco have built their own private exchanges to support collaboration with their suppliers. However, suppliers do not feel comfortable with the idea of being connected to a separate collaboration platform/ exchange for each retailer. A neutral platform operated by an independent third party, which enables information exchange and collaboration between retailers and suppliers in a many-to-many environment, positively contributes to achieving a critical mass on both sides (Hsiao, 2003). On the other hand, neutral marketplaces face more difficulties than private and consortia exchanges, because they need to develop trust relationships among buyers and suppliers before a critical mass of users can be reached (Christiaanse et al., 2004). This statement is also supported by the case presented, where both the old and the new service provider, operating as vertical, neutral, electronic marketplaces or else independent exchanges, faced the problem of building the critical mass of retailers and suppliers. As already mentioned, this is one of the main reasons behind the liquidation of the first service provider. Grieger (2003) further concludes that a reason for failures of electronic marketplaces can be found in the dilemma that operators of such marketplaces concentrated on the integration of information systems rather than on integration of specific business processes, which is also supported by this case, as more emphasis was placed on overcoming the technical challenges rather than the organisational ones. Supplier-retailer coordination challenges One of the reasons that led the initial service provider, OniaNet, to bankruptcy relates to the overestimates of the entrance rate of suppliers into this new form of collaboration with Veropoulos and respective income streams for the service provider. While the suppliers initially appeared enthusiastic about it with clear incentives (in case of success) to participate, several barriers soon had a slow-down effect on their decision to exploit this new opportunity. These relate to the barriers to electronic marketplace adoption mentioned by Hsiao (2003), including technology, organisational, and collaboration barriers. In addition suppliers felt concerned that this was an innovative business process with very local impact, not implemented elsewhere in the world. While this new form of collaboration between retailers and suppliers can be regarded as a new form of CPFR (Pramatari et al., 2002), the suppliers, especially multinational companies, didn’t feel that this process would become common business practice across many retailers in different markets. Regarding the incentives of the suppliers, it was clear (i.e. see Figure 4) that direct-store-delivery suppliers had stronger incentives for adopting the process of collaborative store ordering as for them it represents not only a chance to improve shelf availability but also a cost-reduction opportunity through reduced store visits. Hence it was probably expected that the one direct-store supplier, Elgeka, would remain in the project longer than the others. Moreover, Elgeka as a direct supplier had the human resources to invest in the new system and process: in fact the new system did not require more human capital, since with a single salesman Elgeka was able to manage orders for 20 of the Veropoulos stores through the collaboration platform. The story was very different for the centralised suppliers Procter & Gamble and Unilever: while initially supportive of the initiative, over time it became clear that to succeed these suppliers needed to increase the number of employees working with Veropoulos. Their decision in the past to move to centralised deliveries had been followed by reductions in their sales-force which would now need to be reversed because of the particular collaborative ordering initiative. Given the challenges the initial pilot faced, it was not clear for these centralised suppliers whether it was worth to take the risk and put extra, possibly permanent (human) resources to this program. <<Insert Figure 4 here>> The change over time of the centralised suppliers shows the importance of commitment to such initiatives by all participants. Such initiatives unavoidably face many implementation challenges, as discussed above, so they require strong commitment and involvement of extra resources (i.e. more human capital) by all parties (i.e. the centralised suppliers, too) if they are to succeed. Unlike the case of withinorganisation implementations where commitment can be secured, for example, by strong top-management support over-arching the whole implementation, such “inter-organisational top management” support is, by definition, lacking for multi-party implementations. This makes the commitment of every single party involved crucial. Moreover, the need to increase the sales-force for some of the suppliers (i.e. the centralised ones) shows the organisational impact such initiatives can have to all parties involved. The realization of this need only later in the process also shows how these large multi-party IT-enabled initiatives can have consequences that were not fully expected initially. Had the centralised suppliers committed extra sales people beforehand they may have remained in the project throughout. We also note that in the long run, the adoption of the new system would lead to changes in the roles of the suppliers’ sales force, requiring sales people to work as consultants/ merchandisers, who can identify growth opportunities and become problem-solvers, rather than mere order-takers, who follow a fixed store-visiting schedule. This further implies significant organisational changes, especially for directstore-delivery suppliers, as well as new skills for the sales personnel. The coordination with the suppliers therefore brings up a number of new challenges, beyond the “within organisation” ones discussed in section 4.2. It was thus a wise decision for Veropoulos to go, the second time around, for a solution that would work for the stores internally first, regardless of the suppliers’ entrance rate into the collaboration process. The case shows clearly the importance of first rationalizing the IT systems and processes and implementing e-supply chain modules in-house before starting the creation of more electronic links with the suppliers. CONCLUSIONS In this paper we have presented a case of employing a web platform to support a new process of supplychain collaboration in grocery retailing. The case shows that web technologies can offer companies new alternatives towards achieving strategic business objectives, by enabling new collaboration processes and extended information sharing. At the same time, the case illustrates that collaborative supply chains enabled by new internet technology can be hindered by difficulties in implementing large IT systems. Several technical, organisational and multi-party coordination challenges had to be overcome in order to turn this case from an initial failure to a final success. The initial decision to customize an existing e-procurement platform to support the new collaboration process proved inadequate. Other technical challenges ranged from mastering the various data quality issues and information links, to controlling the various points of failure and achieving a scalable system architecture. On the organisational side, the involvement and proper training of end-users appeared to be one of the major challenges, which required the proper management of top-down and bottom-up communications as well as the alignment of technology with the business processes. Apart from these, the Application Service Provider and marketplace model as well as coordination with suppliers raised issues that were initially underestimated. Moreover, the case suggests that collaborative supply chain IT systems can be easier to execute after the in-house business processes and systems have been properly settled. After the rollout of the new system in 2003 and 2004, Veropoulos has been using it continuously to support the store ordering process to the central warehouse. Three years afterwards, the management of Veropoulos declares satisfied with the use of the system and believes that it has helped them maintain relatively low levels of out-of-shelf. However, periodical trainings of the store personnel are considered necessary in order to keep new people familiar with the system and make the best out of it. Schwarzkopf&Rilken, the first supplier to collaborate with Veropoulos in 2005, currently uses the system for about 40 of the Veropoulos stores, but has not rolled-it-out to all the stores as initially planned. This is mainly attributed to information quality issues with store inventory data, which require that the supplier salesmen visit the store and physically inspect the product inventory quite often, if not each time they place an order. This certainly undermines the benefits of this supply-chain collaboration initiative, since it does not reduce the cost of store ordering as initially expected by the supplier. However, this has not been the case with another retailer that followed shortly after the Veropoulos example. Galaxias, one of the top five Greek retailers with about 100 stores, after an initial pilot with 3 stores, rolled-out the system to all the stores gradually in about a year’s time. The introduction of the system in the new retailer ran smoothly, as the service provider who led the project could build on the lessons learnt from the first case, as explained above. The supplier Schwarzkopf&Rilken, despite having started with Veropoulos, reports today that collaboration with the Galaxias stores has proceeded faster and easier. This, as the Galaxias store people play an active role in monitoring and updating the store inventory data, which allows the supplier to place orders from a distance. This fact, which greatly facilitates the role of the salesman, has enabled two other multinational suppliers, apart from Schwarzkopf&Rilken, to work collaboratively with the Galaxias stores in the ordering process. For several other suppliers the system is used for monitoring product sales for the Veropoulos and Galaxias stores rather than for ordering purposes. The list of challenges mentioned in this paper is obviously not exhaustive. The topic of collaborative supply chains is relatively new, so there is a lot more to learn from various perspectives. In addition, the lessons acquired from this case need to be “transferred” to other organisations with care, since this particular case is from a company in a relatively small and possibly not as technologically mature market, although it is a large company and itself open to new technologies and business practices. On the other hand, the lessons acquired from this case pertain to other supply chain collaboration initiatives, such as CPFR, involving supplier-retailer collaboration in a many-to-many environment and accompanied by organizational changes and coordination issues. From an e-business perspective, the study contributes in presenting practical issues associated with new Internet-enabled supply chain management practices and draws attention to issues other than technical aspects. While the study has been carried out in the Greek grocery retail market, it is relevant to practitioners in other western markets as well, as the big retail chains operating in Greece and their suppliers, which are mainly multinationals, operate in a similar way as in the rest of Europe, as reported in a recent study comparing retail practices in more than seven western European markets (ECR Europe 2005). (I cannot understand this sentence!) More implementations and pilot experiments, other than the first case reported in this paper, are required in order to shed more light on the different aspects of this new supply chain collaboration practice and the enabling role of new e-business infrastructures. Questions relating to the adequacy of the infrastructure, to the business model and operation mode of the collaboration platform, to the motives and barriers to adoption of supply chain collaboration practices and electronic marketplaces are some examples for further research directions suggested by the presented case.

Key challenges and managerial actions: Comparison between first and second phase IT Implementation Model Centralised Pros Cons Easy management of data integration links Data quality need only be maintained in one single system Less expensive as there is only one central node requiring processing power Easy upgrades of hardware and software Slight delays in the system response if accessed in interactive mode In case of a central failure, all the stores are affected De-centralised Faster system response in interactive mode Rather infeasible to get the suppliers involved in the collaboration process A failure in a local system does not affect the other store systems Difficult to manage all the links between the required data sources and all the stores Difficult to maintain high levels of data quality in all store systems Higher cost for software and hardware upgrades More expensive as considerable processing power is required in each store Table 2. Centralised vs. Decentralised IT Implementation NOTES i The reason there was an OOS reduction in the control stores has to do with the fact that the subjects taking part in the experiment (the order decision makers in the stores) take notice of the fact there is a measurement and this influences their behaviour, which is referred to as the Hawthorne effect.
