To-Dos should be discrete tasks that don’t need further explanation to complete. Used for breaking down and distributing updates on a larger task’s progress. Completed to-dos are listed in Basecamp’s daily recap emails.
Do not comment on to-dos, because it creates a new Discussion thread. To-Dos are narrow and rarely revisited, which litters the Discussion section. If discussion is needed about a to-do, create a separate Discussion or break it into smaller to-dos.
To-Dos can be assigned to people and have due dates. Usually not used because tasks are planned in sprints, and are typically only mine.
Note: I’ve been using Trello for sprint planning and task management lately. There are aspects of each I like for different phases of a project. We’ll play this by ear as production ramps up.
