Mind Sweep (Incompletion Trigger Process)
Systematically empty your head of every open loop using category-based prompts
The Mind Sweep is the foundational collection technique of GTD -- a systematic process for emptying your brain of every open loop, incomplete task, unresolved commitment, and nagging thought. The process involves writing each thought on a separate piece of paper (not a list on a single page) and placing it in your in-basket for later processing. Allen recommends allocating twenty minutes to an hour for a thorough mind sweep.
To ensure completeness, Allen provides an extensive 'Incompletion Triggers' list organized into professional and personal categories. Professional triggers include: projects started but not completed, commitments to bosses, colleagues, subordinates, and external parties, communications to make, writing to finish, meetings to set, financial items (budgets, receivables, P&Ls), planning activities, administrative issues (legal, insurance, personnel), marketing, systems, and office organization. Personal triggers cover family, community, health, finances, home, transportation, clothing, hobbies, errands, creative expressions, and end-of-life planning.
The genius of the trigger list is that it provides a systematic scan of every life domain, surfacing items that might otherwise lurk below conscious awareness. Items tend to emerge in random order -- 'save the ozone layer' followed by 'I need cat food' -- and that randomness is a feature, not a bug. Going for quantity over quality ensures nothing is missed. Many of the items that surface will seem trivial, but as the Open Loops Principle demonstrates, trivial uncaptured items consume as much psychic energy as important ones.
- Go for quantity, not quality. It's much better to overcapture than to risk missing something.
- Items will emerge in random order -- personal mixed with professional, trivial mixed with critical. This is normal and expected.
- Write each thought on a separate piece of paper. This makes subsequent processing dramatically easier.
- You'll know you're done when nothing else emerges. If you have even a vague sense that something is missing, keep going.
- Set up your workspace with a stack of blank paper and your in-basketHave plenty of letter-size paper and a good pen ready. Position your in-basket nearby. Clear distractions and commit to at least twenty minutes of focused collection time.
- Free-write whatever comes to mindWrite each thought, idea, project, concern, or task on a separate piece of paper and toss it into the in-basket. Don't filter, judge, or organize -- just capture. Your mind may jump between work and personal topics randomly; follow wherever it goes.Pro tipIf an item triggers other items, capture those too. The flow of association is your brain's natural retrieval mechanism -- follow it.WarningDo not stop to process or organize items as they come up. The collection and processing phases must remain separate or you'll get derailed.
- Walk through the Incompletion Triggers listReview the trigger list category by category -- professional commitments, communications, writing projects, financial items, planning activities, administration, personal life domains, health, home, etc. For each category, ask 'Is there anything here that has my attention?' and capture whatever surfaces.Pro tipRead each trigger item slowly. Often a single word like 'insurance' or 'dentist' will surface a commitment you've been carrying unconsciously for months.
- Continue until your mind is clearYou'll know you're approaching completion when the gaps between new thoughts become longer. Keep going until nothing else surfaces. The typical result is a stack of 50-300 individual items in your in-basket.Pro tipDon't be alarmed at the volume. The size of the stack correlates with the degree of relief you'll feel once it's processed.
A corporate executive works with Allen through the full mind sweep process. After physically gathering items from desk, drawers, cabinets, and shelves, they sit down for the mental collection. Over 45 minutes, the executive captures everything from major strategic initiatives to the dead batteries in a flashlight, from a call he was supposed to return two days ago to a vague intention to reorganize the hall closet at home.
One particularly thorough client took Allen through a mind sweep process that lasted twenty hours before Allen finally said 'you get the idea.' The client had years of accumulated uncaptured commitments across multiple businesses, properties, and life domains.
Allen developed the mind sweep process through working with thousands of clients who were carrying enormous unprocessed inventories in their heads. He found that simply asking 'what's on your mind?' would surface only the most urgent or anxiety-provoking items, leaving hundreds of lower-level commitments still occupying psychic RAM. The Incompletion Triggers list evolved over years of coaching sessions as Allen catalogued every category of life and work that might harbor uncaptured open loops. The one-thought-per-page recommendation (rather than a single list) came from the practical observation that separate items are easier to process and organize individually in the next phase.
