The traditional "quality — speed — cost" triangle, which claims all three goals can't be achieved together, is wrong for highly skilled work.
DORA research confirms every year: strong teams are simultaneously the fastest, the highest-quality and the cheapest. The book Accelerate explains how it is measured.
This is also clear in practice: Instagram grew to millions of users with a small team, and Notion shipped features with a team of 13. A compact structure and low architectural coupling deliver speed without losing quality — everyone understands the product as a whole.
Speed, quality and low cost are not a trade-off but a consequence of engineering maturity.
