With three simple tools—smart prioritization, realistic estimation, and systematic scoping—you can create a practical roadmap for your content, task or feature list. This template helps you bring it all together by automatically creating a single "Value Score" for each of your tasks. When you sort by that score, you can easily see which tasks will create the best "bang for the buck" for the amount of time you have.

This spreadsheet provides a step-by-step method to input a list of tasks—whether that's 10, 50, or more—and then define the priority of each, and estimate them with an easy method. Once you do that, the sheet will automatically calculate which tasks will provide the most benefit with the least effort.
If you have a fixed amount of hours to devote to the project, you can see exactly how much of the work will fit.
