When doing a project it is very common to see your partners have different views of where the project is heading. And that can cause a huge confusion hampering the entire project. Your partners may start taking different approaches and go in different direction. They build up unrealistic expectations and start harboring illogical worries and fears.
You need to have a detailed plan of what the project is and where it will go. Also you have to control and report the mechanisms. There is a way to get everyone and everything on the same page. What you have to do is create a Project Initiation Document or PID. In this you will have to include and document all the information needed for the project to start and for it to be a success. This will also help everyone in your team; understand what the main is aim is of the project.
