The cycle is this:

1. Find - Identify everything that needs to be done
2. Focus - Prioritize the tasks, focussing on the most important
3. Finish (or Fix if it’s more appropriate) - Do the work to finish (or fix) the task
4. Feedback - Get feedback about the work you did and learn from it
5. (Return either to step 1 or 2)

The cycle is iterative. From the last step, you can either go to step 1 and re-identify everything that needs to be done (useful in dynamic environments where the set of tasks is constantly changing) or go to step 2 and re-prioritize the tasks (useful if the set of tasks is unlikely to have changed substantially).

The ‘4F cycle’ is helpful for planning and executing work. It is a simple way to ensure that you are doing the right work and that you are doing the work right.
