In lean projects, we oftentimes find something like a "traffic light" system which helps understand whether an activity is at risk or not. Looking at typical 5 days activities, some clients would like to be able to additionally flag an activity as "at risk" besides the normal 3 types of notes that we have. Yellow for medium risk, red for high risk. Maybe we can introduce a new category of notes in which I can select "At risk" and then define whether it's medium or high risk, attach text and pictures if I want to.
Maybe one addition. When an activity is marked as finished and or confirmed, the flag disappears automatically.
