I agree with you, choosing the right team member for a project is a big factor in the success. In my past job, we used to work in a group called Solution team in general. Some of us were more focused on hardware and software. Part of the project planning is to choose the right team member related to the project. we had 8 decision point for each project. I don’t recall which one was for choosing the team members but I believe it was the 4th step. I’ve seen a lot of projects turned down because of the wrong formation of team due to lack of knowledge or wrong approach
