Write a Checklist You Can Use - Yossi Gerson

By

“Get ready” is a reminder. “Put the charger in the bag” is a step you can finish.

That difference is easy to miss when writing a checklist. The person making the list understands what each item means. The person using it later may be tired, interrupted or trying to leave on time. Even when they are the same person, they need different kinds of help.

A useful checklist makes the next action clear without making a small task feel like a procedure manual. Start with one recurring situation and write for the moment when the list will actually be used.

Name the moment the list begins

“Travel checklist” can mean anything from choosing a destination to checking out of a hotel. A narrower title does some of the organizing for you: “Before leaving for an overnight trip.”

That list starts when the bag is being packed and ends when you leave. Finding a hotel belongs elsewhere. So does planning next month's trip.

Write the starting point at the top. If the same task happens in different situations, keep a short shared list and add only the items that change. A one-night visit and a week away should not require identical preparation.

Use actions with visible finishes

An item should tell you what to do and how to recognize completion. Here are three hypothetical packing reminders rewritten as actions:

Vague reminderAction you can check
ElectronicsPut the phone charger and cable in the bag
ReservationSave the confirmation where it can be opened offline
Getting homeCheck the return time and put it in the calendar

Keep the level of detail useful. “Open the bag” probably needs no reminder. A small item that is easy to forget may deserve one even if it seems obvious while writing the list.

If a step needs judgment, include the question. “Check the weather and choose an outer layer” is more useful than “Clothes.” It leaves room for the actual conditions without leaving the whole task undefined.

Put items in the order you will use them

Arrange the list around the task, rather than the order in which ideas occurred to you.

For an overnight trip, there may be three natural moments: pack the bag, prepare what needs to be accessible during the journey, and check the house before leaving. Moving between those groups is easier than walking back and forth to complete an alphabetical list.

Keep a dependency beside the step it affects. If a device needs charging, that comes before packing it. If the last item cannot happen until morning, mark it “before leaving” instead of making the whole list appear unfinished overnight.

Give exceptions somewhere to go

A checkbox cannot explain everything. Add a small space for “not needed” or “waiting on something.” Otherwise, an unchecked item may mean forgotten, deliberately skipped or impossible to finish.

For a shared list, use a name only where responsibility could be unclear. If two people each assume the other saved the confirmation, the checkbox has not helped much.

The list also needs an end. “Bag packed and essentials checked” is a useful stopping point. A list that expands into every possible preparation can become harder to finish than the task itself.

Revise after one real use

Use the first version once before polishing it further. Then ask three questions: What was missed? What needed explaining? What was checked without adding any value?

Add the missing step, clarify the confusing one and remove the unnecessary one. Keep a dated master copy if the list will be reused, so an old version does not quietly become the default.

For the next recurring task, try this small format:

  • Start when: ______.
  • Finish when: ______.
  • Actions, in order: ______.
  • Exceptions or unfinished items: ______.
  • Change after using it: ______.

The best next revision is usually the one suggested by using the list, rather than another hour spent imagining what might go wrong.
