- It is a big misunderstanding that “(material) quality and speed have a trade-off relationship.
- It is the internal quality in particular maintainability (Ease of testing, Ease of understanding, Ease of Change) that is sacrificed in the name of “quality”.
- In fact, increasing conservatism will increase speed and decreasing conservatism will decrease speed.
- Reducing speed will not improve maintainability, and longer lead times will not allow for the hypothesis testing process.
- The break-even point for investment in internal quality comes surprisingly quickly (within a month). https://speakerdeck.com/twada/quality-and-speed
