The first component of the collaborative process is to create the process itself. This involves the creation of essential guidelines that serve as the framework for how the collaborating parties will work together:

Set ground rules that fit each particular project
Define project scope, goal, and expected results
Discuss leadership
Define roles and responsibilities
Discuss decision making methodology
Set the priorities and milestones
Discuss rewards and recognitions
Teach each other / informal learning pathways
Stay organized
Discuss required resources
Solicit feedback
