Software Design: Tidy First?

Kent Beck argues against premature performance optimization in product development. He outlines three phases: exploration (finding product-market fit), expansion (removing bottlenecks to growth), and extraction (profitable scaling). The key insight is that you cannot predict bottlenecks during exploration, and attempting to build universal infrastructure creates unnecessary complexity. Instead, focus on rapid experimentation early, then quickly address real bottlenecks as they emerge during growth. Premature optimization slows experimentation and reduces the chance of finding a viable product.
