3.3 Project development in BMW Motorcycles

The project development in BMW Motorcycles is a system developed inside the company,

and for its own purpose. It is based on several “Loop” phases, which are responsible for updating the

project with results of test and researches that were meanwhile done.

For every new motorcycle in development, the same integration between departments

needs to occur, in order to provide a good information exchange, and no future concept problems.

There are three departments that compose the team: GR
