Project plan as a criteria for a project list
I just mentioned I don't need project list. That was because most of my projects didn't need any reminder. They were self obvious. For example, I have a goal to train my sales staff. I know that my technical presales is capable to do that. I don't need any project reminder to finish that because it's just one-two steps away: call the presales regarding the training and then wait when it's done. On the other hand some of the projects need to be reminded of. And those projects always require a project plan. Doe example, all of our sales activities require planning.
I think that a criteria of a project that needs to land on a project list is a project plan. If it requires a project plan then it should be on the project list. If not then it's not needed.
