The Pomodoro Technique is a time management method developed by Francesco Cirillo in the late 1980s. The technique uses a timer to break down work into intervals traditionally 25 minutes in length separated by short breaks. These intervals are named pomodoros the plural in English of the Italian word pomodoro (tomato) after the tomato-shaped kitchen timer that Cirillo used as a university student.

There are six steps in the original technique:

1. Decide on the task to be done.
2. Set the pomodoro timer (traditionally to 25 minutes).
3. Work on the task.
4. End work when the timer rings and put a checkmark on a piece of paper.
5. If you have fewer than four checkmarks take a short break (3–5 minutes) then go to step 2.
6. After four pomodoros take a longer break (15–30 minutes) reset your checkmark count to zero then go to step 1.

A goal of the technique is to reduce the impact of internal and external interruptions on focus and flow. A pomodoro is indivisible; when interrupted during a pomodoro either the other activity must be recorded and postponed (inform – negotiate – schedule – call back) or the pomodoro must be abandoned
