Sometimes large projects require the use of multiple designers and teams. These can be accommodated by adding another layer to the preceding scenario like this:
Here three designers and their assigned development teams each individually prototype, code, test and implement parts of the final application using a development cycle like the one defined in Usage Scenario: One Designer – Multiple Developers .
As application components are completed by each team the designer uses the merge tool to create a merge list of the new and updated components. This is sent to the master designer who merges them into a master Framework. The new master Framework is then sent back to each designer to form the basis on which they should perform their ongoing work.
