CONTEXTVS, STVLTE! (Context, stupid!)
summary
Concrete failures and fixes replace slogans: a metric/imperial mismatch causes a 169 kilometers trajectory error that destroys an orbiter and costs $330 million, cultural signals (a beeper) produce a 30-40% performance drop in data entry, track gauge set by Roman chariots constrains rocket booster size, and 25% of the world drives on the left. Root causes get found with 5 whys and fishbone diagram to decompose requirements and pick the right algorithm or index for the actual context.
