How do I apply the idea that bottleneck prevention?

Design three buffers for it: (1) a time buffer — schedule 20% more time than the step typically requires; (2) a stock buffer — maintain one completed output from this step in reserve, ready to deploy if the step fails; (3) a capacity buffer — identify one alternative method or person who could execute this step if your primary approach breaks down. Implement the time buffer this week. Build the stock buffer over the next two weeks. Document the capacity buffer so it is available when you need it.

Common pitfall: Building buffers everywhere instead of at the constraint. You add slack to your morning routine, your email processing, your commute, your lunch break, your evening wind-down — and now your entire day is 40% buffer with no productive density. The system feels spacious but produces nothing. Buffers at non-bottleneck steps are pure waste. They do not protect throughput because those steps were never the limiting factor. The discipline is concentrating protective capacity where the constraint actually forms, not distributing comfort evenly across the system.

This practice connects to Bottleneck Analysis — building it as a repeatable habit compounds over time.
