Other challenges include solutions in increasing market share in the non-CSD industry, capturing untapped domestic market segments. Alternatives In responding to these concerns, several options can be implanted in solving the problem. New product innovation would be accomplished by creating products geared more towards healthconscious consumers. For product improvements, developments include creating a “green coke” with all natural ingredients and revamping Coca-Cola’s PowerAde line through “PowerAde +”. Creating new marketing strategies can be achieved through the implementation of the biodegradable can, and through increased advertising spending in the PowerAde line to build brand loyalty. Establishing new markets would be accomplished through evolving health awareness with products geared towards sustainability and nutrition. Solutions After considering all of the alternatives, we have decided that product development and creating new marketing strategies would be the best route to take. As far as creating new products, no major changes to product lines should be implemented. For product development and new 3 marketing strategies, creating a “green coke” in a biodegradable, released on earth day, would hopefully appeal to health-conscious consumers and ultimately create a new conceptualization of carbonated soft drinks. Introduction Coca-Cola and Pepsi have been in intense competition since the 1970s; however, they have thrived from this competition achieving “average annual revenue growth of around 10%” from the mid-1970s to the mid-1990s. This arrangement was beneficial until domestic demand for carbonated soft drinks (CSDs) began to decline. The carbonated soft drink industry has grown substantially over the years. In 1970, carbonated soft drinks (CSDs) consumed in the United States were 22.7 gallons per capita. In 1998, CSD consumption was 54 gallons per capita. CSD consumption has drastically increased over the last 40 years, but recently has demonstrated level intake, starting in 2000. Coca-Cola and Pepsi are the two main competitors in the industry and as of the end of 2004, control 74.8% of the U.S. soft drink market, with the remainder belonging to Cadbury-Schweppes and other companies. Both Coca-Cola and Pepsi relied on one another for the competition as well as being related to each other for establishing growing revenues. Both companies have expanded their reach into emerging international markets, as well as alternatives to meet the demand of its consumers. In 2005, new federal guidelines were released that identified soft drinks as the main source of obesity-causing sugars in the American diet. After this was realized, schools started prohibiting the sales of CSDs on campus. A survey conducted by Morgan Stanley showed Americans who believed soft drinks were “too fattening” rose from 48% to 59%. This forced CSD manufacturers to direct their energy towards expanding lines of diet sodas and other alternatives. 4 Both Coca-Cola and Pepsi benefited as sales increased and the total U.S. market share grew from 24.6 percent in 1997 to 29.1 percent in 2004. Coca-Cola and Pepsi continue to compete, but it seems that the competition has shifted from competition between each other to competition for attention in a saturated market. This case analysis will focus on the stabilization of growth in the CSD industry and the company’s struggle to maintain market share in the non-carb sector. First, we will examine the goals and constraints currently faced by Coca-Cola. Goals To increase Coca-Cola’s overall market share in the overall beverage industry o To boost flagging domestic demand for CSD products o To increase Coca-Cola’s market share of non-carb products in the U.S. o To capture untapped domestic market segments not catered to by CSD companies Constraints Obesity and health concerns deterring consumers from CSD and unhealthy non-carb beverages Pepsi leads Coca-Cola in market share of non-carbonated beverages, the fastest growing segment of the beverage industry Some domestic market segments won’t associate with large companies like Coca-Cola due to negative political and environmental connotations (i.e. socially-conscious consumers, eco-conscious consumers) 5 Competitive Analysis Porters 5 Forces Model is a valuable tool in evaluating the state of the CSD and non-carb industry that Coca-Cola and Pepsi actively dominate. While there is much competition between the two companies, it is arguable that they fuel each other’s growth. This can’t necessarily be said for smaller companies like Cadbury Schweppes who are in a constant state of falling behind in market share. Porter created this strategy to give an in-depth view of the state of any given industry and determine the feasibility of entering, but also to outline the level of competition being dealt with by already established participants in said industry in order to reposition themselves for further growth. Thus, Porter gives the 5 Basic Competitive Forces and suggests analyzing each one in the scope of the industry—CSD and non-carb beverages. 1. Barriers to Entry In the beverage industry, largely dominated by Coca-Cola and Pepsi, the barriers to entry are high due to several key factors. First, a company trying to break into the CSD market must compete with Coca-Cola and Pepsi’s combined market share of over 75%. Economies of scale come into play because both companies have the capital and production abilities to produce their flagship and additional products for much cheaper than a start-up that is breaking into the business. A major factor in the CSD and non-carb industry now is differentiation, with both companies attempting to find new ways to appeal to customers without straying too far from their cornerstones of success (ex: New Coca-Cola vs. Coca-Cola Classic). The recent growth of the non-carb beverage industry is a good area of focus for a new company, but the product must be novel in order to catch on and then have staying power. Another barrier to entry could potentially stem from legislation to regulate health standards. Companies must develop ways to address 6 health concerns and invest in research and development to do so. Another issue is that mainly Coca-Cola has put most small bottlers out of business and bought them out to add to their top bottler, Coca-Cola Enterprises. This makes it more difficult for a new concentrate producer to introduce a cola product, because the options for bottling and distribution are limited. Ultimately Coca-Cola and Pepsi have formed an oligopoly in the industry, making it difficult for new entrants to expect profitable gains upon entry. However, between each other the companies must constantly innovate and invest in order to keep up with each other. 2. Rivalry As discussed in the previous section, the competition in the CSD and non-carb industries is a stronghold between Pepsi and Coca-Cola with a few minor players holding a miniscule amount of market share. When there are many competitors entry is easier, but when economies of scale come into play smaller competitors can get crowded out or bought out by a larger one. In this case, the top two companies in the industry create almost all of the product being sold, creating a high stakes market where Coca-Cola directly benefits from Pepsi losing market share. As a former CEO of Pepsi put it, “Without Coca-Cola, Pepsi would have a hard time being an original and lively competitor. The more successful they are, the more competitive we have to be.” The competition between Coca-Cola and Pepsi is very reciprocal, with the companies responding to each other’s strategy shifts, much like in chess. Coca-Cola began developing its international market in the 1950s, when distributors were set-up in other countries during WWII. Focusing on those markets, by the 90s Coca-Cola had a bolstering international market while domestic sales were dropping. Pepsi responded to 7 this by trying to infiltrate the markets that Coca-Cola had already developed, but soon realized that competing in those already established markets was costly and not the best move, and then turned their attention to untapped markets. Coca-Cola is clearly the leader in CSDs, which forces Pepsi to constantly reposition itself in terms of what CocaCola is doing. The same goes for the non-carb market, which Pepsi has gained market share of. Due in large part to health concerns and product innovation, consumers have been looking for alternatives to carbonated beverages and Pepsi capitalized on this trend at the right time. With Pepsi’s Gatorade leading Coca-Cola’s Powerade by almost 50%, Pepsi has been more successful in that area of the market, something that Coca-Cola has taken note of. It is a costly market to enter and once in it, a company needs to realize at least their fixed costs before exiting, cementing Coca-Cola and Pepsi’s domination of the market even more. 3. Substitutes Entering a market with a generally undifferentiated product leaves one open to the threat of substitution. Coca-Cola and Pepsi, for all intents and purposes, both have relatively similar flagship colas, but have fought consumers from thinking that with intensive advertising and marketing campaigns. Both companies have developed much customer loyalty, especially with their flagship products, making them much less substitutable than if those loyalties weren’t in place. Consumers tend to choose based on price if there are no other reasons; therefore, the companies have had to develop these reasons in order to retain share versus store and generic brands. In terms of the rest of the CSD and non-carb brands produced by these companies, there is more interchangeability that can often result in consumers just choosing the lower prices, which is why Coca-Cola and Pepsi 8 must remain in such close competition. If they can remain within the same price range of products, it then forces consumers to choose based on preference. 4. Power of Buyers In the 90s when Coca-Cola and Pepsi attempted to raise their retail prices between 6 and 8 percent, consumers reacted by buying much less of the products and grocery sales for the companies went down significantly. This forced both companies to re-evaluate their pricing and lower the margin by which they raise prices, which had a positive effect on retail consumption. This is an example where both Coca-Cola chose a higher pricing strategy, Pepsi followed suit, and consumers reacted negatively. However, in its bottler relationships Coca-Cola and Pepsi have a greater ability to impact pricing without experiencing backlash; therefore, the buyer power of bottlers is low. First, most of Pepsi and Coca-Cola’s bottlers are owned by them and are forced to take price increases set by each company’s master bottling contract (which are supposed to fluctuate with CPI, but don’t always do). Those bottlers that were independently owned couldn’t put up with the price changes and eventually went out of business or were bought out by one of the two companies. 5. Power of Suppliers In this case, supplier power is very high. Bottlers are unable to negotiate with Coca-Cola and Pepsi due to stringent franchise agreements, giving the companies power in pricing and quantity. Coca-Cola and Pepsi are both powerful because they have integrated most of their processes and can benefit directly from profits. With their acquisition of most of 9 their bottlers and door-to-store format, they are able to monitor their product from beginning to end and give little opportunity for their bottlers or retailers to negotiate. Central Issue Given that the overarching goal of Coca-Cola is to capture as much market share of the beverage industry as possible, we have identified Coca-Cola’s central problem as the waning demand for CSDs in the domestic market; this has created a stagnant growth for the company and a decline in market share of the beverage industry. It is important to identify this problem over the other issues because up until recently Coca-Cola had a healthy hold on the overall beverage market and is now seeing that lead decline to Pepsi, due in particular to Pepsi’s strength in the growing non-carb market. Coca-Cola has often relied on its flagship CSDs to maintain growth, but since demand is dwindling for carbonated beverages the company must decide on an appropriate course of action in order to reach the ultimate goal of dominating the overall domestic market. We believe that the future success of Coca-Cola hinges on how the company chooses to react to this reduced demand for their mainstay products. Alternatives Coca-Cola could react to waning domestic demand for CSD products in many ways, through new product innovation, product improvement, intensified marketing strategies, or creating a new market altogether. We believe that choosing to focus on increasing demand in the CSD market or increasing Coca-Cola’s presence in the non-carb sector are the two best options as our alternatives represent. The company can either attempt to enter into a If Coca-Cola chooses to impact CSD demand directly, alternatives could include developing new marketing 10 strategies to boost CSD demand, new carbonated product innovation to increase CSD demand, or creating an approach that links new promotional approaches with product innovation. However, Coca-Cola could also choose to move away from the CSD industry and focus on competing more directly with Pepsi’s share of the non-carb market. In doing this, Coca-Cola is reacting passively to the problem of stagnant domestic demand for CSDs, but could benefit by using more resources to improve Coca-Cola’s existing non-carb beverages and to develop new non-carbs that can compete more readily with Pepsi’s. Our first alternative focuses on Coca-Cola increasing their marketing and promotional strategies in untapped consumer segments. Coca-Cola is not typically associated with being a socially conscious or sustainable company, especially in the United States. However, given the various awards and recognitions listed on the company’s website, including ranking #10 in Fortune Magazine’s 2010 list of the “World’s Most Admired Companies” due to environmental initiatives and good business practices, Coca-Cola should capitalize on their image in the business world and translate that to consumers.1 Advertising the positive initiatives of the CocaCola Company could create an immediate draw from consumers who typically dismiss the company as just another corporate giant. According to the Chicago Tribune, 2010’s food trends included going green, buying local, a search for simplicity, and comfort foods.2 Coca-Cola could very easily advertise about the green initiatives the company has undertaken, enticing ecoconscious consumers who search for more than just the value of the product. Two other trends beneficial to Coca-Cola are simplicity and comfort. In recovering from the recession, people are looking for a return to normalcy and being able to enjoy the small things. Coca-Cola has long been associated with the United States, a recognizable symbol of home. Reintroducing classic marketing slogans like “Always Coca-Cola” could incite nostalgia and help reenergize people’s 11 interest in Coca-Cola’s flagship CSDs like Coca-Cola Classic and Diet Coke. Some drawbacks to this strategy are that the magnitude of political controversy that has surrounded Coca-Cola may not be undone by promoting Coca-Cola’s good deeds, people who are against the company may not be able to get turned back on. Also, while people are seeking a return to simplicity, the fact of obesity and health concerns remain, which these marketing strategies do nothing to address. Another alternative to boost CSD demand domestically is to innovate its existing CSDs to create new demand in the existing market. Coca-Cola has always used a traditional marketing angle focusing heavily on its flagship CSD products, thus the focus on staying within the CSD market—it’s what they’re the best at. Differentiating too much, to the point of abandoning the CSD sector of the beverage industry, could give the impression that Coca-Cola is abandoning its roots. Some options for innovating existing products include additives with health benefits (antioxidants, tea extracts, vitamins, etc.) and using alternative sweeteners (cane sugar, stevia, etc.). These innovations have the potential to directly address health issues and those consumers with “green” preferences. A fear that comes with innovating Coca-Cola’s CSDs, especially its flagships, is the backlash these products could face. “New Coke” was a huge disappointment and an example of just that, Coca-Cola differentiated to the point of abandoning the original and consumers reacted negatively. However, our recommendation is not to replace the flagships, just offer differentiated versions that could appeal to an untapped market for CSD consumption. Combining the previous two alternatives presents the final alternative that focuses on directly addressing the decreased demand for CSD products in the U.S. Using an integrated marketing and product innovation approach, Coca-Cola could develop modified versions of its flagship products— Coca-Cola and Diet Coke—and present them through a multi-faceted 12 marketing strategy. The product innovation could include ingredient alteration, like the sweetener recommendation, new packaging, and present these changes to the public. According to the Wall Street Journal, Coca-Cola recently released new packaging dubbed the “plantbottle.” Derived from a process involving sugar cane, this is an example of a green initiative Coca-Cola has successfully undertaken.3 This new, green packaging is being used currently for the flagship CSDs and water, but a powerful strategy would be to combine the package with a healthy product. Since we’re attempting to overcome the public’s increasing fear of obesity and further health issues (for example, growing concern over the use of high fructose corn syrup) a factor contributing to CSD decline in the U.S., the innovation in the product should take that into account. In addition, there are the previously discussed trends of eco-friendliness and simplicity. We see this alternative coming together in the form of developing and marketing a more natural version of Coca-Cola’s flagships, conscientious of both consumer health and the environment. The challenges that this alternative presents are that both health conscious and green consumers deem CSDs might never consider Coca-Cola’s items beneficial because of pre-existing notions about the company. Also, the actual effectiveness of green packaging, marketing, and a healthier alternative might be negligible compared with costs and consumer reaction. If Coca-Cola claims to provide a healthier product and the benefits are proven otherwise, the company could come under fire for misleading advertising. While the previous set of alternatives has focused on boosting domestic demand for carbonated beverages, another strategic approach Coca-Cola can take is strengthening its participation in the non-carb market. A recent article in Financial Times discusses the strategy selected by current PepsiCo CEO Indra Nooyi, saying that when faced with the declining CSD market she chose to steer the company in a direction where they could definitely be on top.4 13 Moving towards the non-carb market, Pepsi has captured that sector of the beverage industry and now Coca-Cola is struggling to recapture some of the market share that Pepsi has gained. The first alternative dealing with non-carbs could be to reformulate some of its products, such as Minute Maid or Nestea, to better compete with Pepsi’s successful health and functional drinks. Our recommendation is to focus on a pre-existing Coca-Cola product with potential for demographic marketing and the ability to be improved given consumer health and wellness standards; specifically PowerAde. Coca-Cola’s PowerAde sports drink line should capitalize on health trends and market more specifically in college and professional sports leagues. Livestrong, a popular sporting website, conducted a comparison of Gatorade and PowerAde, down to the ingredients.5 While Gatorade used to be produced with a mixture of sugar, glucose, and fructose, the formula has more recently been produced with high-fructose corn syrup. PowerAde is also sweetened with high-fructose corn syrup and additionally has more carbohydrates, but additional vitamins. Choosing to reformulate original PowerAde to use an alternative sweetener could give them an edge in the competition. Completing the new formula would entail improving old and creating new flavors to market as PowerAde +. To create a more fresh conception of the PowerAde brand, two or three flavors could be created with seasonality in mind—for example, releasing limited edition flavors specifically for the Olympics or World Cup. If Coca-Cola chooses not to reformulate its sports drink product, another option would be advertising more heavily in the college and professional sports markets. For sports markets, increased advertising at the collegiate and professional levels would primarily be geared to develop trust in the PowerAde brand and ultimately correlate Coca-Cola more closely with athletes and fans. In 2004, PowerAde held 0.9% share in advertisement spending compared to 14 Gatorade, who held a 3.9% share. Increasing spending in PowerAde’s advertisement could be directed towards university conference and NCAA partnerships, as well as creating endorsement deals with top tier athletes. Offering universities the option to adopt PowerAde as their “official” drink through special price deals would increase brand distribution not only through increased product visibility, but also through apparel, banners, and promotions. Coca-Cola could also offer incentives at the professional level, negotiating to become the official sports drink of the National Basketball Association, Major League Baseball, the National Football League, the National Hockey League, etc. This effort is ultimately meant to gain brand loyalty for PowerAde on college campuses and in the professional sporting arena, which should spur more consumer demand. The final alternative Coca-Cola could pursue to compete more aggressively in the noncarb market is to develop an entirely new product, consistent with emerging trends in the beverage industry. In a recent article from Beverage Daily, they note that global sales of probiotic and prebiotic drinks were up to $15 billion dollars in 2008. This is a product market that neither Pepsi nor Coca-Cola have gotten very involved with, but could potentially succeed in.6 This is only one example of how Coca-Cola could use emerging health and wellness trends in the beverage industry to their advantage. As the leader in overall beverages, becoming a mass producer of a product with increasing demand could put them in the lead in the non-carb market. However, while this a feasible option, it may not be the best solution to increasing market share. Coca-Cola does not yet have the credentials to tout healthier products, because the image is still rooted in carbonated “junk food” beverages. Also, while this trend is on the rise, it may be a passing fad that could end up costing the company revenue. Best Alternative 15 The best new market strategy we chose to implement, is a shift towards a more health and Eco-conscious demographic. A new “green” or all natural formula along with a new biodegradable can planned to be released in a celebratory fashion on earth day, to attract our target demographic as well as spark a surge of “green-friendly” consumers that will associate the Coca-Cola name with their new life-style. This name association would help Coca-Cola sales increase with the new wave “green” consumers. We also decided that we would forgo a completely new brand or formula of the Coca-Cola product due to past experience had by the Coca-Cola Company. Although the new Coca-Cola formula is modified in the new natural version, the actual recipe stays the same just with more organic ingredients. The goal is to make the same great tasting Coca-Cola Classic only with less unnatural flavorings. With only minor changes on some of the ingredients cost should be kept minimal, and keep the return on the investment high. Along with this new market strategy’s potential up sides, there are potential down sides. The major down sides will result from unseen costs or shifts in the consumers new purchasing patterns. However potential gain in market share significantly out-weigh the small threat that it imposes on the use of Coca-Cola’s resources. These steps are a small investment in not only Coca-Cola’s market share but in the betterment the world we live in. Implementation Strategy Ultimately we feel that our third alternative focusing on sustainability in the Coca-Cola brand is more advantageous in our increasingly eco-conscious and health focused society. The new product line of “green” Coca-Cola would initially be introduced, marketed, and distributed to a domestic audience. Calling it “green” suggests the development of an all-natural product, the use biodegradable bottling, and an eco-driven marketing approach. If domestic consumer 16 reception of Coca-Cola’s eco-friend CSD is positive, the company should plan to expand distribution worldwide within six months. Coca-Cola’s first step is to invest in the innovation of their “green” CSD line. Developing a natural formula consists of finding alternative to the ingredients in their flagship products. The initial concern is with the types of sweeteners used in Coca-Cola and Diet Coke. While abroad, in countries like Mexico, Coca-Cola is made with real sugar, but due to cost reductions the bulk of Coke products in the U.S. are made with high-fructose corn syrup.7 Similarly, Diet Coke is typically produced with aspartame and recently a sucralose (Splenda) formula was released. A more natural alternative to that is the use of stevia, a naturally derived sweetener recently approved by the FDA.8 Among the benefits listed by Mayo Clinic are the fact that the sugar substitute helps with weight control. Another consideration for both products is reducing the amount of artificial dyes used in their production as well as considering the addition of nutritional extracts. In terms of bottling, Coca-Cola has already invested in a biodegradable packaging through their PlantBottle which is composed of 30% plant material and 70% traditional petroleum products. The company originally began using the bottles to package their Dasani Water product, but eventually plans to be integrated as part of regular packaging for all products. Ultimately, Coca-Cola envisions a 100% renewable bottle and with much research and development, they should be able to move out of the development phase rapidly. Package design should be altered to reflect the product’s goals, which are to appeal to a more eco-conscious consumer, express Coca-Cola’s commitment to environmental responsibility, and educate the general population. Placing the universal symbol for recyclable on the packaging in an eyecatching way, rather than on the bottom in an inconspicuous place could help achieve this goal. 17 Recycling should also become increasing important to help lower bottle manufacturing costs and continue the social image of sustainable Coca-Cola products. Coca-Cola could consider investing in recycling plants or providing more recycling receptacles to the retailers it distributes to. Creating an incentive program would be the best way to increase demand for this new product, offering deposits on bottles paid through the company. In this way, Coca-Cola could also track the number of consumers of their new product. The following is a chronology of the marketing proposal: June 2011 – Create partnership with recycling networks, work on incentivized recycling program November 2011 – Begin advertising through television, radio, print, and on the internet. Create a presence at Earth Day events, eco-rallies, etc. January 2012 – Release “green” Coca-Cola Product in U.S. (domestic bottling and distributers) February-March 2012 – Evaluate domestic consumer response to new product through consumer surveys, bottle returns, and sales Early May 2012 – Begin worldwide marketing beginning with test markets (i.e. select countries in Europe), move to larger markets April 22nd, 2012 (Earth Day) – Create anticipated promotional event, release product worldwide Ultimately, if Coca-Cola’s green formulation is successful, then combined with the proper marketing the company could help boost the demand in the CSD market domestically and improve their standing, making Pepsi’s dominance in non-carbs a non-issue. 18 References Yoffie, David.
