A schedule without gaps assumes instant transitions and zero probability of delay.
Planning is useful when it helps you make the next decision and notice changed conditions. It cannot guarantee execution: deadlines, health, other people, and ordinary surprises remain part of the system.
The short answer
A buffer is planned capacity for normal uncertainty. It is not empty time that must be filled in advance.
Start by protecting one 30-minute reserve before the nearest important deadline. After a week, use the actual interruptions and overruns to refine its size.
Where buffers belong
Different uncertainty needs different reserves:
| Location | What it absorbs |
|---|---|
| Between meetings | overrun, notes, a short reset |
| After travel | delays and transition back into work |
| Before a deadline | checking, corrections, missing inputs |
| Inside the week | tasks displaced by ordinary changes |
Do not use the same number everywhere. A familiar ten-minute administrative task needs less reserve than a new project involving several people.
A practical setup
- Find where delays and context switches happen repeatedly.
- Add small gaps between different kinds of work.
- Keep one larger reserve block during the week.
- Do not assign a task to the buffer before a real need appears.
- If it stays free, use it for rest or a task from the optional queue.
For example, leave ten minutes between meetings, avoid difficult work for thirty minutes after travel, and protect one hour on Thursday afternoon for weekly shifts.
Check whether the buffer is working
Ask:
- Does it absorb normal variation?
- Is it always consumed by work that was underestimated from the beginning?
- Do transitions take longer than expected?
- Is “emergency work” arriving from the same source every week?
If the reserve is always occupied in advance, it is no longer a reserve. Reduce planned load before adding another buffer.
Common mistakes
- filling every available hour;
- treating a moved task as a personal failure;
- ignoring preparation, travel, and recovery after switching;
- using the buffer to hide systematically unrealistic estimates.
In Flammy, keep the result in the season goal and track only the nearest or recurring actions. A weekly review can show whether your schedule needs a larger reserve or a smaller planned workload.
