Protocol
Park the current goal before an unavoidable interruption
Use the few seconds before the switch to preserve the goal you are about to drop.
When it fits
- You can see an interruption arriving and the current task has an intermediate state you will need to reconstruct later.
When to avoid it
- The evidence comes from laboratory interruption studies. A cue will not prevent every error, and safety-critical work may require a formal handoff or checklist rather than a personal note.
Why it matters
If the interruption cannot be avoided, encode a retrieval cue before disengaging. Write the current subgoal, the last verified state and the next action or condition. Experimental work shows that preserved contextual cues can reduce resumption cost, and a broader review finds that interruption-management interventions can improve accuracy and resumption speed on average. The point is not to document the whole task; preserve the minimum state that can reactivate it.
Steps
- Name the current subgoal in one line.
- Record the last verified state or decision.
- Write the exact next action, question or condition for resumption.
- Handle the interruption, then resume from the cue before scanning the whole task again.
An example
Before answering an urgent message during a data check, write: 'Batch 3; rows 201–300 checked; row 247 unresolved; next: compare KNVP source for 247.'
Check your result
After the interruption, the cue is sufficient to restart without reconstructing the task from memory or rereading everything.
Keep this limit in mind
- The evidence comes from laboratory interruption studies. A cue will not prevent every error, and safety-critical work may require a formal handoff or checklist rather than a personal note.

Evidence and sources
A 2021 systematic review of 33 laboratory experiments found that interruption-management interventions improved primary-task accuracy on average (SMD=1.03) and reduced resumption lag (SMD=-0.51), with effects varying by intervention type and task type.
The studies were laboratory-based and heterogeneous; the estimates do not define one universal interruption protocol for professional work.
Experimental work found that having an opportunity to encode retrieval cues before an interruption reduced later resumption cost, and changing those contextual cues after the interruption impaired recovery.
The result comes from controlled problem-solving tasks and supports the general value of preserving task context, not a specific note-taking tool.
