reflection The comparative case study resulted in new insight into the research area organizational culture and project partnering performance. Therefore the methodology fitted the explorative research character. The research model of a linear analytical structure proved to reduce the complexity of the research by consequently following the different research steps. Nonetheless certain aspects of the research method are worthwhile to reflect upon. Therefore certain aspects of the methodology and case studies are discussed. A reflection is also provided for follow-up research by fellow Master students. Methodology Discrepancy in time between organisational culture and project partnering performance measurement In the methodology, a retrospective case study approach was selected in order to prevent time consuming observations, increase the availability of relevant documents and to increase the openness of the actors. The main research question was: “What is the influence of organisational culture differences between the architect and the contractor on project partnering performance in design and build projects?”. This question emphasizes two variables: organisational culture and project partnering performance. Due to the retrospective research approach, both variables should reflect the measurement at a specific point in time in the past. During the case study of ‘De Brug’ it became clear that the measurement of organisational culture in the past (2005) – with the use of this particular interview – does not provide the necessary information to describe the organizational culture in the past (2005). Difficulties arose with the interviewees, when answering the questions regarding the organisational culture in the past, despite the specific emphasis on the time difference by the interviewer during the interview. The answers regarding the organisational culture variables reflected the present organisational culture instead of the organisational culture in the past (2005). Therefore there is a discrepancy in time between the measurement of the organisational culture which was intended (organisational culture in 2005) with what it has become (organisational culture in 2012). Due to the fact that organisational culture is a dynamic concept and changes over time, the organisational culture was probably significantly different in the past compared to the present. Especially with the added external influence of the economic crisis on organisational culture within the last few years. Therefore, the discrepancy in time reduces the content validity for the case study ‘De Brug’. The discrepancy in time within the case study ‘BioPartner Accelerator’ was ignored because the time difference had been too small to make a significant difference in the organisational culture since 2010. Despite the discrepancy in time in the case study ‘De Brug’, the influence of the organisational culture (2012) has been compared with the project partnering performance (2005). Limited depth in the description and analysis of organisational culture The organisational culture of the architect and the contractor was described and analyzed by using the external adaptation variables (external adaptation – mission and strategy; goals; means; performance measurement; correction method) (Schein 2004: 88). The variables relating to the integration of the internal processes of the group (internal integration – creating a common language and conceptual categories; defining group boundaries and identity; distributing power and status; developing rules for intimacy, friendship and love; allocating rewards and punishment; managing the unmanageable) (Schein 2004: 112) and the macro culture (reality, truth, nature of time and space and human nature activity and relationships) were ignored due to time restrictions on the research. The decision to restrict the research by ignoring the variables regarding internal integration and the macro culture, implies a lack of depth in the description and analysis of the organisational culture of the architect and the contractor. In order to get a more in-depth description and analysis about the organisational culture of the organisations the theory of Schein should be fully applied. In other words, a description and analysis about the artefacts and the variables related to the integration of the internal processes and to the macro culture should be incorporated. As the variables related to the integration of the internal processes (Schein 2004: 112) were ignored, the variable to describe the specific internal design process of the architect was not taken into account. The internal design process is a decisive characteristic of the organisation of the architect and has a strong influence on the basic assumptions of the organisation. Van Doorn (Doorn 2004: 49) acknowledges the differences between the organisation of an architectural firm and general businesses on several aspects. One of these aspects is the internal designing process. Another aspect with which a more in-depth description can be created is to increase the number of interviews about organisational culture. Contradictions between the answers regarding the variables are valuable information to determine the basic assumptions about the organisation. Furthermore, a historical description and analysis about the choices of the organisation and why these choices have been made (a more ethnographic research approach) can provide valuable input in order to determine the basic assumptions of the organisation (Schein 2004). The ethnographic approach also reduces the subjectivity of the organisational culture description by finding contradictions between what the organisation claims to be and what they actually do. This thesis described the organisational culture by what the organisation claims to be, through the use of single interviews with the supervisors. The restrictive methodology to determine the organisational culture of the architect and the contractor caused a limited description of the organisational culture of the architect, because the decisive organisational culture variable – internal design process – was ignored. Moreover, the description of both contractors’ subcultures was not extensive enough to distinguish the contractors’ sub-cultures, even though other factors could also explain the difficulty to distinguish the subcultures of the contractors. These factors could be: the contractors (Dura Vermeer Bouw Leidschendam and Dura Vermeer Bouw Rotterdam) are departments of one large organisation (Dura Vermeer); the strong collaboration between both departments due to a collaborative business unit (PCS construction systems); and the limited separation of the departments from one another (Dura Vermeer Bouw Leidschendam was established 12,5 years ago due to the separation of the department Dura Vermeer Bouw Rotterdam). Nonetheless, it can be concluded that the method of measuring the organisational culture – through the five variables related to the external survival of the company in its environment (Schein 2004: 88) – is a too superficial method. Although the method provides an indication for certain basic assumptions of the company, it does not provide the necessary broadness and depth in order to determine a definite and objective organisational culture description. The case studies Discrepancy between project partnering in theory and strategic partnering in empirical data Project partnering is defined as: “A commitment between two or more organizations during a single construction project for the purposes of achieving specific project objectives by maximizing the effectiveness of each participant’s resources. This requires changing traditional relationships to a shared culture without regard to organizational boundaries. The relationship is based on trust, dedication to common goals, and an understanding of each other’s individual expectations” (adapted from CII 1991). Explicit differences between project partnering and strategic partnering is the commitment to one project (project partnering) and two or more projects (strategic partnering). For the case selection the most important criterion was the application of project partnering. This implied that the actors were participating together in one single project. During the case studies it became clear that the architect and the contractor knew each other and had a mutual project history. The architect and the contractor have completed different types of projects, where they played different roles. Within the formal definition this implies that, not project partnering but strategic partnering, has been applied (collaboration within multiple projects due to supply chain integration). Therefore a more thorough analysis of the definition of project and strategic partnering is required. In the definition of project partnering the former experience between the participants and the project type (the type of project refers to the variety of functions a building can have, e.g. house, office, laboratory, library) were not discussed, even though these aspects are important to further clarify and distinguish project partnering from strategic partnering. Therefore, the project partnering definition is re-defined as: “A commitment between two or more organizations during a single construction project – with no former experience between the project participants on similar project types – for the purpose of achieving specific project objectives by maximizing the effectiveness of each participant’s resources. This requires changing traditional relationships to a shared culture without regard to organizational boundaries. The relationship is based on trust, dedication to common goals, and an understanding of each other’s individual expectations”. Limitations of the two case studies The results are based on a single case and the proposals are based on two cases. Therefore, it is not possible to generalize the results or the proposals. For this reason the results and proposals should be considered in the context of the two cases. In order to validate the proposals, further research is required. The two selected cases were very successful construction projects for all the project actors. The results and proposals of an explorative case study depend on the type of case and the success of the results of the cases. If the cases had shown difficulties during the process or had a dissatisfying result, it could have provided different and interesting results and proposals. Therefore, it would be interesting to extend the study by applying the methodology to cases that have been subjected to an unsuccessful process or have had a dissatisfying result. Further research Influence of competences and values of organisation on personal level in the project According to Hofstede (2010: 348) and Schein (2004: 225) the founder exposes his values to the members of the organization and these values become a part of the new members. Within JHK Architects the members are selected by the supervisors, thus the supervisors try to find a person that suits the company and is probably sensitive to the values that the supervisors will expose on him when a new member enters the organization. According to Blau (1984: 27) several architectural companies claim that “new staff are hired because they will be congenial and will fit in; they should be people with the same ideas or similar philosophy”. This was recognized within the case studies. Moreover, it was also recognized that certain competences and values of the members of JHK Architect were recognized in the project team by the contractor. Examples of these values were: dedication to the construction team; look further than own interests; technical and functional design vision and the central client. Figure 8.1 shows a concept drawing of the influence of competences and values on a personal level in the project team. The influence of competences and values of the organisation on a personal level in the project could be of interest for further research. Further exploration of the research subject The research subject can be explored more extensively. This thesis resulted in the possible relationships of the organisational culture variables on the project partnering variables. These were presented in four propositions (Chapter 7). In order to find out whether the possible relations are significant, quantitative correlation research should be done. The propositions could also provide a base for further correlation research. Furthermore, new possible influences of the organisational culture on the project partnering performance could be explored, by re-applying the particular methodology on different case studies. It would be very interesting to extend the organisational culture measurement method with ethnographic research methods and increase the organisational culture variables with the integral integration and macro culture variables (Schein 2004: 112), in order to explore the possible influences of the organisational culture on project partnering performance from different perspectives.
