CAPÍTULO 7. EVALUACIÓN DE LA EFECTIVIDAD DE LA APLICACIÓN

9. BIBLIOGRAFÍA

One of the three most important goals to be announced at the press conference of the DaimlerChrysler AG takeover in May 1998 was to improve customer satisfaction (DaimlerChrysler AG Video Appendix 1.1). However, one of the most obvious shortcomings of the paradigm of lean production and mass production in the 1990s was quality at both Chrysler and Mercedes. At the time of the takeover announcement in May 1998, Chrysler had reduced its development times to 24 months. At the same time Mercedes had brought out 10 new models in the previous 3 years. That compares significantly with the three new models, which had been launched in the previous ten years before 1995. Although both companies were able to achieve commercial success, quality issues started to crop up very quickly.

The measurement of quality of a particular vehicle is widely accepted within the industry. In the United States of America customers turn to J.D. Power (Initial Quality Study and APEAL) and Consumers Report, two institutions that monitor customer satisfaction and measure technical reliability respectively. J.D. Power’s Initial Quality Study (IQS) is particularly telling, because it measures defects, malfunctions and design-based issues within the first 90 days of ownership. Their benchmarking provides an industry-wide comparison of mistakes per vehicle, which is generally accepted as an objective measurement of vehicle quality. In the case of Mercedes models, specially prepared cars are tested at the company’s Long Beach Vehicle Preparation Centre (VPC) in California. So if these vehicles have problems they are truly indicative of general manufacturing and quality issues. In addition J.D. Power’s APEAL direct customer survey measures the rate of satisfaction of customers after the first ninety days of ownership of the vehicle of their choice. APEAL results have always been more controversial than IQS results because APEAL does not measure whether a Toyota is better than a Mercedes APEAL rather measures whether Mercedes customers are more satisfied with their Mercedes than Toyota customers with their Toyotas. Since dominating the rankings in the late 1980s and early 1990s J.D. Power rankings both for IQS and APEAL have always

Jürgen Schrempp constantly defined and reiterated the goal of Mercedes’ quality offensives to reach the Number 1 ranking (DaimlerChrysler AG Annual Meeting April 6th 2005). J.D.

Power also conducts a Vehicle dependability Study (VDS), which monitors reliability after three year’s ownership, but this study does not match the industry’s focus on IQS and APEAL. Moreover, the increasing globalization of J.D. Power’s activities with expansion of its survey to Europe and Asia has also augmented its influence within the global automobile industry. Toyota, for example, used their high J.D. Power rankings in their attempts to expand their share of the German market.

Although Consumers Report is less known in Europe than J.D. Power, it is a major annual publication for the car industry in North America. The magazine is published by Consumers Union, which is a non-profit consumer advocacy organization, acting in the interests of consumers since 1936. The magazine’s rejection of outside advertising has allowed it to achieve a reputation for fairness and objectivity. As will be shown further below, the negative ratings for Mercedes vehicles in the first decade of the 21st century contributed to the devaluation of the Mercedes brand.

A third instrument for measuring quality is the governmental National Highway and Traffic Association (NHTSA), which provides open access to its database documenting comprehensively all safety recalls and technical defect investigations for all makes and models of vehicles registered in the USA. One example from the Mercedes-Benz M-Class (Figure 15) is included here to illustrate the comprehensive nature of NHTSA reporting. A full list of recalls for the Mercedes M-Class and E-Class vehicles during the critical years for Mercedes quality under Schrempp is included in the NHTSA Recalls Appendix (281 ff.).

Because NHTSA recalls draw attention to serious safety issues, they are indicative are further underlying quality issues at any manufacturer. Safety doubts are particularly damaging to brands, such as Mercedes, which make safety a central component of their overall brand image. Recalls affecting the E-Class were particularly damaging to the overall customer perception of Mercedes quality in the USA.

A fourth source of quality “information” is certainly the numerous Mercedes owners’ forums and Internet chatrooms. Although the objective understanding of the precise technical nature of certain issues cannot be trusted, the growing amount of “bad noise” between 1998 and 2005 does indicate to a certain extent the general level of customer dissatisfaction.

On the German side, the situation is less objective. Privacy laws are much tighter than in the USA. Furthermore, the industry tends to limit studies for internal use only and there is an understanding within the German car industry not to use this information against competitors (Wall Street Journal February 4th, 2001). Furthermore, studies such as the German Automobile Association’s ADAC “Pannenbericht” (car breakdown report) are less reliable instruments of quality and tend to put non-German manufacturers at a disadvantage. If a Mercedes driver has a breakdown, for example, they can notify the Mercedes call centre directly and that defect does not appear in the official statistics. Secondly, vehicle recalls are triggered by OEMs themselves and no public database is available as is the case with NHTSA. Thirdly, German car magazines depend heavily on advertising investments from the German OEMs and there is a close relationship between the magazines and the OEMs. The current head of Mercedes-Benz motorsport, for example, Norbert Haug, was the former head of Auto, Motor and Sport magazine. Fourthly, critical consumer publications such as Stiftung Warentest do not have the facilities to test cars in the same manner as Consumers Report.

Consumers Report’s April issue on car quality and dependability is an annual event in the USA and the most important issue of the year for car buyers. Within this coordinated network of “protected” information in Germany, monitoring newspaper reports of consumer dissatisfaction provide important clues to the current quality status and customer satisfaction.

In the case of Mercedes one of the most important customer bases are German taxi drivers.

Perhaps more than any other customer segment, German taxi drivers helped to contribute to the brand’s reputation for product quality, reliability and durability. It is therefore worth

noting the increasing dissatisfaction of this group beginning with public protests against the bad quality of the W124 in the 1980s (Der Spiegel 48, 1986). This public and vocal dissonance grew louder in the 1990s and first decade of this century.

Using all of these instruments the next sections will attempt to show that the DaimlerChrysler AG takeover did not cause “quality” problems at Mercedes and Chrysler, but rather served to augment and deepen the quality crisis at each company respectively. The discussion will focus on the Mercedes brand because its dramatic drop in industry ratings was the most critical quality event during the existence of DaimlerChrysler AG. It is also significant that Mercedes quality ratings started to improve after the disbandment of DaimlerChrysler AG.
