What is a weekly review?
Short answer
A weekly review is a short, regular session, often 20 to 30 minutes, where you look back at the past week, collect loose ends, and plan the next one. It comes from popular productivity methods and has little direct research behind it, but looking back before planning ahead fits research on why people underestimate how long things take.
During the week, tasks scatter: notes in your phone, papers in your bag, emails you meant to answer, promises made in passing. A weekly review is the moment you gather them all, decide what matters, and start the next week with a clear head.
Where it comes from
The weekly review is best known from David Allen's Getting Things Done method, and it appears in many other planning systems. It is a popular habit, not a researched intervention. We did not find studies testing weekly reviews by name.
Why looking back helps planning
A weekly review builds that step in. By noticing what took longer than expected last week, you can plan the next one more realistically.
A 20-minute weekly review
These are general strategies, not treatment.
Collect (5 minutes)
Gather loose notes, check your email for things you flagged, empty your bag, and scan your messages for promises you made. Write every open item on one list.
Look back (5 minutes)
- What got done? A done list helps here if you keep one.
- What slipped, and why?
- What took longer than expected?
Look ahead (10 minutes)
- Check next week's calendar for appointments and deadlines.
- Choose a few priorities for the week.
- Give each priority a specific time.
- Decide what to drop or postpone on purpose.
Weekly review versus weekly plan
A weekly plan looks forward. A weekly review looks back first, and then plans. The backward look is what catches unanswered messages, stray promises, and tasks that keep slipping. If you already plan your week, adding a few minutes of looking back is often the easiest upgrade.
Making it stick
- Schedule it like an appointment, same day and time each week.
- Pair it with something pleasant, like a favorite coffee shop on Friday afternoons.
- Keep a checklist so you do not have to remember the steps.
- If you skip a week, do a shorter version rather than waiting for the perfect time.
ADHDFalcon has free focus tools that can time each part of the review and hold your list for the week.
A hypothetical example
For example, someone might do their review every Friday at 4 p.m. They collect three sticky notes, two flagged emails, and a voice memo. Looking back, they see that two big tasks slipped because meetings took most of Wednesday. Looking ahead, they block Wednesday morning, choose three priorities, and move one low-priority task to next month. The whole thing takes about twenty minutes.

Frequently asked questions
How long should a weekly review take?
Often 20 to 30 minutes. A shorter version is better than skipping it.
What day is best for a weekly review?
Any day you can repeat. Friday afternoon and Sunday evening are common choices.
Is a weekly review backed by research?
Not directly. It is a popular method. Related research suggests looking at past experience leads to more realistic planning.
