Personal Kanban: A Simple Board for Finishing What You Start

The two rules: visualize your work and limit work in progress

The first rule is to make all your work visible. Not just the tasks you remember on Monday morning, but the errands, the half-written emails, the favor you promised a friend and the project that keeps nagging at you. When work lives only in your head, it feels larger and vaguer than it really is. When it is on a board, you can count it, compare it and decide what matters.

The second rule is to limit how much work is in progress at once. This is the rule people skip, and it is the one that does most of the good. Every task you have open costs a little attention, even when you are not working on it, because part of your mind keeps track of where you left it. Switching between many open tasks also means repeatedly reloading context, which is slow and tiring. A limit forces you to finish something before you start something new.

Designing your columns

Start with four columns and resist adding more until you have a clear reason. Backlog holds everything you might do. This week holds what you have committed to for the current week. Doing holds what you are actively working on right now. Done holds what you have finished. Cards move from left to right, and only the Doing column has a strict limit.

Some variants are genuinely useful. A Waiting column is the most common addition, because a lot of personal work stalls on other people: a reply from a supervisor, a delivery, a form being processed. Moving those cards out of Doing keeps your limit honest without losing track of them. Beyond five or six columns, though, the board starts to describe your process in more detail than you need, and maintaining it becomes a chore.

Physical or digital? Sticky notes on a wall or a whiteboard are powerful because they are hard to ignore, and moving a card to Done by hand has a small but real satisfaction. A digital board travels with you, can be updated from your phone and is easier to organize with colors or labels. Choose the one you will actually look at every day; trying to keep two boards in sync usually ends with both going stale.

• Backlog: everything you might do, unsorted is fine.
• This week: what you have committed to finishing in the next seven days.
• Doing: what you are actively working on, with a WIP limit.
• Waiting: started, but blocked on someone or something else.
• Done: finished work, kept visible until your weekly review.

Setting a WIP limit for one person

For an individual, a WIP limit of two or three cards in Doing is a good starting point. One is often too strict, because real life includes a main task plus something small that is waiting for a short gap. Five or more defeats the purpose; at that point Doing is just a second backlog.

The limit will feel uncomfortable, especially in the first week. A new task arrives, Doing is full, and you feel the urge to start it anyway. That moment is the method working. You have three honest options: finish one of the current cards, move one back to This week if it was started prematurely, or move it to Waiting if it is genuinely blocked. Breaking the limit should be a conscious exception, not a habit.

It is fine to adjust the number after two or three weeks of observation. If you constantly hit the limit while tasks are still flowing to Done, raise it by one. If cards sit in Doing for days without moving, lower it.

Sizing cards so they actually move

A card that never moves is demoralizing and tells you nothing. The most common cause is cards that are too big. 'Thesis' or 'Renovate the kitchen' are projects, not cards. A good card describes a piece of work you can finish within a day, ideally in one to three focus sessions, and it starts with a verb: 'Draft methods section 3.2', 'Email three tile shops for quotes'.

Big projects still deserve a place on the board, but not as single cards in Doing. Give each project a color, or keep a short line of project cards at the top of the Backlog, and break off the next two or three concrete steps as separate cards. When a card has been in Doing for more than two days, treat that as a signal to split it rather than as a sign of personal failure.

The weekly grooming session

A board left alone slowly fills with stale cards until you stop trusting it. Fifteen to twenty minutes once a week keeps it useful. Friday afternoon or Sunday evening works well for most people. The point is not to plan every hour, but to make sure the board reflects reality and that This week contains a realistic amount of work.

A useful test for capacity: count the focus sessions you completed last week, and do not pull more work into This week than that number allows. If you managed twelve sessions, a week asking for twenty-five is a wish, not a plan.

• Look at Done, acknowledge what you finished, then archive or clear it.
• Review Doing: anything stuck gets split, moved back or moved to Waiting.
• Check Waiting and send any follow-ups that are due.
• Pull cards from Backlog into This week, up to your realistic capacity.
• Delete or archive Backlog cards you have ignored for more than a month or two.

Example: a board for a master's thesis

A thesis is a classic case for Kanban because it is long, vague and full of waiting. A workable board might use five columns: Backlog, This week, Writing (WIP limit 2), With supervisor, and Done. Each chapter gets its own color, so you can see at a glance whether one chapter is being neglected.

Typical cards in This week might be 'Summarize the four papers on sampling bias', 'Draft section 2.3 on data collection', 'Fix the figure numbering in chapter 1' and 'Prepare three questions for Thursday's meeting'. When you send chapter 2 to your supervisor, that card goes to With supervisor instead of sitting in Writing for two weeks. The board then shows a truthful picture: you are not stuck, you are waiting, and you have room in Writing for chapter 3.

Example: a household board

Kanban also works well for a home, especially one shared by two or more people. A whiteboard on the fridge or a shared digital board with Someday, This week, Doing (WIP limit 3), Waiting and Done is enough. Cards might include 'Book the boiler service', 'Return the wrong-size shoes', 'Sort winter clothes' and 'Compare electricity tariffs'.

The Waiting column earns its keep here: 'Technician coming Thursday', 'Refund requested on the 3rd'. Without it, these items sit in your head as low-level worry. A shared board also makes invisible work visible to everyone in the household, which tends to reduce the 'I didn't know that needed doing' conversations. Keep it light, though; a household board that requires a meeting to update will be abandoned.

Pairing your board with focus sessions

A board tells you what to work on; a focus timer helps you actually do it. The simplest pairing is to start a session only on a card that is in Doing. If you notice yourself starting a session on something that is not on the board, either add it or ask why you are doing it now.

Session counts also make card sizing more objective. If cards usually take two or three sessions and one has quietly absorbed seven, it needs splitting. In Opcus you can keep a personal Kanban board next to the focus timer and give tasks a target number of sessions, so the plan and the work sit in the same place. Over a few weeks you will develop a feel for how many sessions a typical card takes, which makes the weekly grooming much more accurate.
