This forum should support each group as they brainstorm together to build mind maps about their ideas for their project.
Brainstorm together to answer these questions: Who will build your project? What will the benefits be? When will it be implemented? Where will the context be? Why will your project succeed? How will it overcome obstacles?
Should your team only make one mindmap? Or should individual team members mind map to illustrate their OWN perspectives and ideas on the project? In my experience, teams are often led by people who really WANT to lead a project, but may not be the best at coming up with new ideas and creative solutions...
Post your mindmaps in your group areas, and then give feedback, or ask questions, to at least two other teams...
