I call this a "terminal" thought because it leads to a disastrous method of project management: panic. Panic management occurs when organization goes out the window; and that's exactly what happens when all issues are prioritized the same. The priority indicator loses its value. Even when time is running short and all of the issues are crucial to launch, issues varying levels of priority and some need to be done before others. And what happens when nothing has any priority? Developers decided themselves which issues to do and when.
When we get to crunch time, I think it's appropriate to not only redefine the spans of time for the Timeframe factor but redefine the factor. Instead of thinking about a Timeframe, think about a Sequence:
- Urgent: Drop everything and work on this
- High: Complete before working on any lower priority issues
- Normal and Low: After confirming with the project manager that there is nothing more important that needs to be done, concentrate on the Normal priority issues first but may incorporate Low priority issues if there's an efficiency advantage. Low priority issues are completed last.
