Parkinson's Law
Origin
Cyril Northcote Parkinson originally published the law in 1955 as a humorous article in The Economist magazine, and a year later as a book. He observed that, in bureaucracy, the time devoted to a task tends to fill all the time allotted to it, regardless of the actual complexity of the work.
Effects of Parkinson's Law
- Procrastination: if a long deadline is set for a task, people tend to put off the actual work until the deadline approaches. Urgency is what ultimately triggers action.
- Unnecessary complexity: when additional time is available, it is common to consider more alternatives, make marginal improvements, or create problems that require additional attention.
- Unproductive perfectionism: the extra time is spent on refinements that add no value to the final result.
How agility combats Parkinson's Law
Agile frameworks incorporate specific mechanisms to counteract this effect:
- Timeboxing: sprints, meetings, and tasks have a fixed maximum duration. The time limit drives prioritization within it.
- Kanban: continuous flow without time-based milestones prevents last-minute work buildup, but it requires a WIP limit to prevent procrastination.
- Short iterations: a one- or two-week sprint creates cycles of controlled urgency that prevent work from piling up and long-term delays.
- Clear Sprint Goal: a well-defined Sprint Goal helps the team prioritize which work deserves the available time and which does not.
Common mistake
Ignoring Parkinson's Law when estimating. If, when planning a sprint, the team overestimates the time needed for a task "just in case," the task will tend to fill all of that time even though it could have been finished sooner. Estimating in ideal time and honoring sprint commitments is more productive than adding a safety margin that Parkinson's Law will end up consuming.
