I am currently using Tasks by Planner addon to my Team site to serve as a solutions bank. Baskets are organized by common tasks and processes. Under each, we have problem cards. Each card has a description of the issue/causes. As we discover solutions to the problem, we add them as checklist items, attach pictures, tip sheets or other documents.
The application is ok, but I know I am going outside the intent of the planner tool, so I sometimes have issues. People complete the task, which hides it. They assign or put due dates on them. They may accidentally move them into the incorrect basket. Is there a better Microsoft application that would meet my purpose?
