Make appropriate note in project materials for later action and/or adjust project plan on the spot and/or adjust next action list on the spot.2. It is part of an active project but I had not considered this aspect. I need to make a note of this and incorporate it into project planning. Or, , it changes the next action on my list (a good reason to try to associate actions with projects). For example, I went to replace a battery in a receiver and found I needed to order a new housing that holds and the battery in place. To find the part number I have to take the old housing apart, for which I need to identify the size tool I need and then get it. But, my next action after replacing the battery and getting this gizmo to work was to order a special cleaner for it (independent) but I am not going to clean it if I can't get the new battery housing anyway.
File it with other materials related to the someday/maybe project for later review.3. It is a someday maybe, but I don't know yet if it will stand alone or be part of a project. I need to remember to incorporate it when I plan the project and when I decide if the project is active or not.
Drop everything and get to work on the project if possible. Look at calendar and schedule a slot if not.4. It is so important that it will make me want to make the project active as soon as I can.
Treat as any other action, though you might want to review your system for reminders of routine actions to see if changes are needed.5. It is actually part of a routine but no one has been doing it routinely, either because no one was thinking about it or no one wanted to.
