Secondary criteria for good reminders
| Comprehensive | A good reminder should be able to work effectively for a wide range of acts to be remembered acts |
| Compel | A good reminder should (when warranted or possible) compel the actor to perform a necessary task/act by blocking further progress until the act has been completed |
| Confirm | A good reminder should help the actor to check that the intended acts have been carried out as planned (i.e. it must continue to exist in a useful fashion after the time for action has passed) |
| Convenient | A good reminder should not cause unwanted or additional problems, particularly if these turn out to be worse than the omission |
| Conclude | A good reminder should be readily removable once the time for action and checking has passed |
