Parkinson's Law
Work expands to fill available time.
Takeaways
- 1
Open-ended tasks feel heavier than bounded ones.
- 2
Set expectations for how long a flow should take.
- 3
Constrain inputs when brevity is the goal.
Origins
Parkinson’s Law observes that tasks grow to consume the time allotted to them. In interfaces, unbounded text fields, vague prompts, and endless configuration can make simple jobs feel exhausting.
Clear constraints help users start, finish, and move on.
Design Applications
- Use character counts for summaries and messages.
- Break large jobs into timed or numbered steps.
- Autosave so users are not afraid to pause and return.
