- Capture the what, where and who
- Filter out completed items
- Sort by trade and location for ease of use
- Paperless (as much as possible)
- Allow comments/questions
- Allow photos
- Support authoring
All of these can manage a list. The challenge is finding a tool that doesn't require a purchase or a learning curve for the contractors or for you. Those criteria eliminate most of the tools above as well as the possibility of interactivity and the need for authoring.
