I believe that in the case of prioritizing projects, a company shouldn’t move everyone from one project to the next according to prioritization. But they should decrease the number of employees working on a low priority project. The projects themselves should not be cancelled because their prioritization might change in the future. For example, in my company when we have a project that’s low priority this week, we move some employees around to make them work on higher priority projects. But we keep a few employees still working the lower priority project. This is because the next week might come and the priorities get shifted. I also think this should be based off how big that project is. If the project is very demanding (requires a lot of employees) and is moved to low priority, it shouldn’t be cancelled or decommissioned. If a project is small and moves to lower priority, maybe the company should think about moving it out of scope.
