System Design Principles
Occam's Razor
Prefer the simplest solution that works.
Takeaways
- 1
Remove UI that does not serve a clear user need.
- 2
One primary action per screen reduces hesitation.
- 3
Complexity should earn its place with measurable value.
Origins
Occam’s Razor advises choosing the explanation — or solution — with the fewest unnecessary assumptions. In product design, that translates to fewer competing actions, cleaner flows, and less cognitive overhead.
Simplicity is a discipline of subtraction backed by evidence.
Design Applications
- Audit screens for redundant controls and duplicate paths.
- Merge overlapping settings into one clear control.
- Ship the smallest version that solves the core job.
