Iā€™m reprinting here an article I wrote for Hatena Diary in 2012, which was automatically reprinted on Hatena Blog, because I received a reference to it on Twitter. src: About Pomodoro - NISHIO Hirokazuā€™s Hatena Diary


  • About [pomodoro editing I tweeted about it on Twitter when asked, so Iā€™ll summarize it here so it doesnā€™t drift away.

First of all, those who say ā€œ1 pomodoro in 25 minutes, so in 8 hours, thatā€™s 16 pomodoro?ā€ should understand that that is as strange as saying ā€œa human can run 100 meters in 10 seconds, so he should be able to run 4200 km in 4200 secondsā€. You cannot maintain the speed of a short-distance runner in a long-distance run. People who make such calculations based on ā€œworking 8 hours a dayā€ do not understand Pomodoroā€™s goal of ā€œconcentrating and achieving results in a short period of timeā€ in the first place.

This is not my way of interpreting the situation. If you have read even the preface of the Agile Time Management: An Introduction to the Pomodoro Technique, you will immediately recognize the misunderstanding. It states. I thought I could do 12 Pomodoro minutes a day. However, when I opened my eyes, I found that 8 pomodoros at most was a realistic lineā€ (quoted without the part not related to the meaning of the sentence).

The rest is an introduction to how I do things.

BGM First, I made a playlist of about 28 minutes of songs that I have been using for work background music for some time, and I listen to it with muffled headphones while I work. The last song is a slow one. It kind of tells you that the end is near. The last song that tells me that the end is near is included to avoid being startled when my work is suddenly interrupted by a buzzer, or conversely, to avoid being so focused that I donā€™t notice the buzzer. It takes time to bring the work to a satisfactory conclusion.

Since this is the background music, I do not use a tick-tock timer. I was annoyed with timers whose tick-tock sound was slightly delayed by the work load, and I also wondered if it would be a good idea to actively make the sound at work in the first place.

  • (Supplement 2019)
    • Using a physical tick-tock timer is a good idea, but I didnā€™t use it because I didnā€™t think it would be a good idea to make a ā€œtick-tock, jingleā€ sound at work.
    • I tried the tic-tac-toe app on my phone, but stopped because of the tic-tac-toe timing delay.

timer The iPhoneā€™s standard timer has a silent end tone and a 25-minute countdown. I can see the remaining time at a glance. However, since I basically judge the end by the music, I think it might be better without it. When I look at the timer and see 1 minute and 30 seconds left, I feel like itā€™s too short to do anything and Iā€™m wasting my time.

The disease of wanting to create task management software Engineers tend to say, ā€œIs there any good task management tool? But now I manage my tasks with sticky notes and notebooks. I can work more easily now than when I was trying to do something digitally through trial and error. I understand the desire to create a good software, but why donā€™t you first identify what kind of specifications are necessary by using the alpha version of the paper version? Paper may be sufficient for your needs.

tag By the way, I forget what size the sticky note is called, but itā€™s the size of the throwaway paper in the bottle-shaped gum container. Itā€™s like writing one pomodoroā€™s worth of tasks and leaving a blank space. The margin allows me to write a little more, but not so much that I hesitate to throw it away when the task is done. Itā€™s just right.

(PS: This is itā€¦4cm*5cm in size. http://www.mmm.co.jp/office/post_it/list01/653rp.html )

These sticky notes are divided into temporary variables, and if they are no longer needed after they are out of scope, I immediately roll them up and put them in the trash. When I used to use larger paper, I would strike out the ones I no longer needed, but it was ugly. Iā€™ve since become comfortable with the size of the paper, which I can throw away mercilessly.

If you use a large piece of paper for your task list, you will end up writing things on the task list other than ā€œwhat you need to focus on now,ā€ and then you will see them while you are working, which will cause unnecessary processing. The list with all the tasks should be placed somewhere out of sight while you are working. For this reason, I use small sticky notes for ā€œcurrent task.

Another advantage of using small stickies is that tasks that have been written but not executed become physical ā€œstickies that stay on the desk all the timeā€ and gradually lose their adhesiveness and seem to fly away in the wind. If you donā€™t want to lose them, they are ā€œnon-urgent but important tasksā€ and should be done with care, otherwise, donā€™t do them. If not, donā€™t do it. Roll it up and throw it away.

certificate Also, this is something my wife has educated me on. In the past, I used to use the monthly spread of my notebook for writing ā€œfuture plansā€ and did not look at it very often. My wife, who is much more experienced in her work than I am, uses it differently. She keeps a daily log of her ā€œpresentā€ as well as her appointments, and the past dates are basically filled in. The benefits of this.

First of all, the frequency of opening a notebook increases overwhelmingly. Especially for R&D workers like myself, we donā€™t have many appointments because we donā€™t have many appointments with other people. If you donā€™t have many plans, your notebook will be empty, and you wonā€™t look at it very often, and as a result, you will forget to write things down or look at them, making it completely meaningless.

This is something I learned in What you need quickly! Organizational skills to get what you need out of the way!, but the techniques in tidying books by people who can tidy up assume that ā€œthings have a fixed place and are put back there regularly.ā€ It assumes that ā€œthings have a place and that you put them back there regularly. Itā€™s too obvious to mention, but thatā€™s the basic premise. If the basic premise is not fulfilled, copying techniques alone will not work. Pomodoro and GTD are the same, and I think the implicit basic premise is that ā€œthere must be a list of tasks, and it must be reviewed and updated regularly.

If I had had a job when I was younger that involved meeting with a lot of people or having a lot of meetings, I might have learned how to use a notebook naturally. Unfortunately, I did not acquire this ability until recently. I started using the same notebook as my wife the year before last and tried to imitate how she uses it, and as a result, two months ago, a situation began to develop where the notebook is checked every day, the Pomodoro accomplished on that day is written in the notebook, and the past dates are basically filled in. Iā€™m getting much better at estimating the amount of work I can do in one pomodoro. I feel like I am in control of my concentration.

Sticky (Added on 2012-10-02) I write the pomodoro I plan to do tomorrow on a single sticky note and stick it in my notebook (often).

Review it in the morning when you put it on your desk at work and revise it if necessary.

Work. Each Pomodoro sticky note is thrown away as soon as the Pomodoro is finished, but ā€œwhat has been completedā€ is recorded by checking a check mark on this ā€œTodayā€™s Task Sticky Noteā€.

At the end of the day, transcribe the completed pomodoros into the notebook and discard the sticky note.

Often, while performing a task, I think of a ā€œtask that should not be done now. I write it on a separate sticky note and stick it in my notebook. The notebook is usually closed, which prevents me from getting distracted by other tasks while I am executing them. I review it during breaks between Pomodoros, during the Pomodoro, and at the end of the day to decide when to do it and when not to do it.

Not much time (Added on 2012-10-02) I canā€™t estimate the time for debugging or anything; I started one pomodoro and it took me five minutes.ā€ What do I do with the other 20 minutes?ā€ I see. It often happens that a part of the Pomodoro is left over as a result of trying a task that is difficult to estimate. What do you do in those situations?

Since the start is not clear, it is not suitable for doing ā€œsomething completely differentā€ that requires a fresh start. Therefore, it is better to do something related to the work you have just done. Among those tasks, it is better to do ā€œtasks that do not take much timeā€ or ā€œtasks that can be separated by time. For example, tasks such as ā€œdownloading a document that I will need laterā€ or ā€œcleaning up the sticky notes on my deskā€ are likely to be completed quickly and will increase the productivity of the Pomodoro, the task that follows. Tasks such as ā€œGoogling and researchingā€ or ā€œflipping through a reference bookā€ do not have a clear goal and time cannot be estimated, so they tend to be done lazily if done without a time limit. They are suited to ā€œskimmingā€ time.

Past Articles Pomodoro started. A year and a half ago. A fresh diary of the day I just started. Compared to those days, I have much less ā€œdistractions during the pomodoro caused by meā€. Pomodoro Reconsidered Article 3 months after starting. The mistake of working without turning the timer has not gone away yet. I wonder if it is because I havenā€™t done the measurement of the mistake of not turning the timer after all. This article also did not turn the timer. Sequel Pomodoro The effect is to move forward with one task a day, even if you donā€™t feel like it. It is important not to immediately put a newly arising task on the ā€œto do todayā€ list if it is not urgent. Pomodoro and PDCA Cycle The ā€œIā€™ll do it todayā€ declaration is followed at the end of the day by a ā€œDid you do it?ā€ check at the end of the day. If you just put it in the task list, even if you donā€™t do it on that day, the check will not run. Pomodoro is here - Togetter Summary Pomodoro talk by nishio and yoshiori - Togetter Summary
