Design and Process of Social Change 141 mechanical engineering departments. When the final design was com- pleted, it was then returned to the accounting and sales group for pricing and cost calculations. Once the final budget was priced and shared with the client, the back and forth process of price negotiations between the cli- ent and the company's sales and engineering teams began. This process usually took about six to eight months to complete at an estimated cost of around $500,000. Over time, both the timetable and the associated costs surrounding each bid increased at an annual rate of 5% and this was becoming a major source of friction between the company and its customers. After reviewing the situation it was obvious that we needed a modular design. But the traditional culture with its strong functional structure was not ready for the kind of change that modular design requires. To reduce resistance to change, we proposed a simple experiment to see if there were other alternative processes the company could consider to reduce cost and improve timing. The experiment was to create a learning cell involv- ing four junior engineers, one from each of the engineering divisions, in addition to a cost accountant and a sales engineer from the sales depart- ment. Each member of the learning cell was asked to teach the remaining
