The industry’s focus shifted from desktop PCs to mobile computing, software, and technology services areas of relative weakness at Dell. Due to a changing industry, the company’s original business model based on direct sales and value chain efficiencies had been abandoned. It was now using the same distribution channels, component providers, and assembly contractors as its competitors. Unfortunately, Dell’s emphasis on cost reduction and competitive pricing meant that it was no longer perceived as providing high-quality personal computers or the quality service to go with them. Previously a strength of the company, its customer service rating in 2005 fell to a score of 74 (average for the industry) in a survey by the University of Michigan. Complaints about Dell’s service more than doubled in 2005 to 1,533. Although the company successfully worked to improve customer satisfaction by adding more service people, more people meant increased costs and smaller margins.
