How ALPEN helps build a daily plan
ALPEN consists of five daily-planning operations: list tasks, estimate duration, leave a buffer, make decisions, and review the result. Start with available time: if meetings and breaks leave four hours, tasks and buffer together must fit those four hours. When the list exceeds this boundary, change the workload or agreements.
Below is one completed card you can repeat on paper or in a note. It shows the initial plan, a decision when a new task arrives, and the evening review. Every task, estimate, and actual minute figure is illustrative.
Five ALPEN steps
A TU Darmstadt SchreibCenter learning sheet describes the following sequence. It explains how to apply the technique rather than guaranteeing a result for everyone.
- A — Aufgaben aufschreiben: list tasks. Give each a clear outcome and mandatory deadline if one exists.
- L — Länge schätzen: estimate duration. Include preparation and checking if they belong to the chosen task.
- P — Pufferzeiten einplanen: leave a buffer. Separate unassigned time from meetings, travel, and rest already counted.
- E — Entscheidungen treffen: make decisions. Choose what to do today, reduce, move, or agree with participants.
- N — Nachkontrolle: review the outcome. Compare estimates with actual figures, completed priorities, and buffer use; apply findings to the next plan.
The letters matter as a sequence of checks. A list without duration estimates does not show the load. Estimates without a buffer leave the day vulnerable to delays. Evening completion marks do not replace decisions about what to change tomorrow.
A complete ALPEN card: estimate, buffer, and decisions
An illustrative workday: meetings, their preparation, lunch, and breaks are already accounted for separately. Four hours remain, or 240 minutes for selected tasks and buffer. This is total available capacity; also check before starting whether each task fits a specific free window.
The initial list takes 180 minutes: a 60-minute task, a 90-minute task, and a 30-minute call. Of the available 240 minutes, 60 remain. At step P, explicitly label them as buffer without an assigned task. At step E, confirm the chosen work is actually needed today and fits free windows.
| Step | Card entry | What is checked |
|---|---|---|
| A — tasks | Prepare report questions; check a finished document; hold an agreed call. | Each task has a clear result. |
| L — duration | Questions — 60 minutes; document review — 90 minutes; call — 30 minutes. Total 180 minutes. | Estimates include necessary actions within each task. |
| P — buffer | 240 minutes available. After 180 minutes of tasks, 60 remain unassigned. | Meetings and rest are already subtracted and not counted again as buffer. |
| E — decisions | Keep three tasks. Document review can move by agreement if more urgent work appears. | A specific rescheduling candidate is named. |
| N — outcome | In the evening, record actual minutes, buffer use, and decisions on remaining work. | The card ends by adjusting the next plan. |
The 60-minute buffer here is an illustrative choice rather than a recommended standard. Until delays arise, this hour remains unoccupied. Assigning another job in advance removes the buffer even if the row still says ‘buffer’.
What changes if a new 90-minute task arrives
Suppose an urgent 90-minute clarification request arrives before the plan begins. Tasks now total 180 + 90 = 270 minutes. This exceeds the available 240 minutes by 30 even with no buffer. Retaining the previous 60-minute buffer requires 330 minutes overall, 90 more than available.
In our example, the finished-document review can move while the clarification is needed today. Agree on the review’s postponement with its recipient and record a new date. After replacement, tasks again total 180 minutes: report questions 60, urgent clarification 90, call 30. The 60-minute buffer remains.
- Clarify the new task’s deadline and minimum needed result before changing the plan.
- Recalculate remaining tasks and buffer against the time still available.
- Name the specific task being moved or reduced and agree on the change if others are affected.
- If every task is mandatory today, discuss a changed deadline, scope, or help. Recording a new task does not add time.
If the request arrives midday, the original 240 minutes are no longer fully available: some time has been spent. Repeat L, P, and E for the remaining day, accounting for completed work, upcoming commitments, and remaining buffer.
Evening review: estimate, actual result, and next plan
Step N closes the loop: check not only marks but reasons for differences. In the illustrative outcome below, the revised plan was completed. Tasks took 200 rather than 180 minutes, and an unexpected question took another 15. Of the 60-minute buffer, 35 were used and 25 remained.
| Task | Estimate | Actual | What to change |
|---|---|---|---|
| Report questions | 60 minutes | 75 minutes | Data checking was omitted. Estimate it separately in the next similar task. |
| Urgent clarification | 90 minutes | 95 minutes | Wording review took another 5 minutes; include it next time. |
| Call | 30 minutes | 30 minutes | Estimate matched; retain the record as a reference. |
| Unexpected question | Not assigned beforehand | 15 minutes | Count as buffer use rather than the planned call. |
| Document review | 90 minutes before postponement | Not performed | Postponement agreed. Check available window and deadline before the new day. |
| Buffer | 60 minutes | 35 minutes used | 20 minutes of task overrun + 15 for the question; 25 minutes remained free. |
This record gives a specific correction to L: include data checking when next estimating question preparation. The postponed document review does not enter tomorrow’s plan automatically; compare it again with commitments and available time.
One day provides an observation rather than a stable standard. Examine several similar tasks before trusting a new estimate as a reliable reference. If the buffer is regularly exhausted, review the selected work volume and placement of free windows.
Must I always follow the 60/40 rule?
The TU Darmstadt sheet calls a 60/40 split between planned time and buffer a guideline and notes that it is often difficult to maintain in practice. It is not a universal percentage standard.
Our card assigns 180 of 240 minutes to tasks and 60 to buffer. This ratio was chosen for an illustrative example. For your day, consider task predictability, incoming requests, and past differences between estimates and actual time. Lunch, known travel, and planned breaks remain separate time costs.
Where to keep the card and what to read next
Paper or a note with five lines, A, L, P, E, and N, is enough. If you already track tasks in Sinqly, save selected next actions and the postponed document review there. Keep estimates, buffer, and evening comparison in the card itself. You perform the calculation and decisions; this example requires no separate automatic ALPEN mode.

Frequently asked questions
Can I use ALPEN without an app?
Yes. Record tasks, time estimates, a separate buffer, decisions, and the evening outcome on paper or in a note. You need to be able to recalculate load and record plan changes.
What if task estimates exceed available time?
Reduce scope, move a specific task after necessary agreement, or discuss help and deadlines. For example, 270 task minutes do not fit 240 minutes even if you abandon the buffer entirely.
Should I move everything unfinished to tomorrow?
No. Check relevance, deadline, and next step for each unfinished item. Reassess workload and available time before adding it to a new day.
What if the buffer is unused?
Leave the time free or choose extra work while considering remaining commitments. Preserve the original plan in the evening record and mark added work separately so the comparison retains meaning.
