Draft outline details
Step by step
- Start with the situation: a search service costs a given amount per month at p99 of 120 ms.
- Find options: smaller cache, fewer replicas, and coarser indexing that raise p99 by 10 ms and cut cost about 25% (verify by measurement).
- Measure customer impact: check whether 10 ms changes conversion in an experiment or historical data.
- Present the trade-off to product and finance: saved cost, risk, and rollback.
- Planned mistake: accept the saving without measuring impact. Fix: run an experiment, set a guardrail, and decide with data.
- Record the decision, budget change, and review date.
