The Secret Assumption of Agile
summary
Claims concrete metrics: agile projects use tests‑first, tiny classes and continuous integration to make change cheap. Case studies show 12‑month vendor bids turned into 8‑month deliveries at $1.1M vs $2M (≈6× productivity), legacy 72 classes becomes 1,400, estimated 500,000 LOC shrinks to ~60,000 plus 65,000 tests (~80% reduction), average method ~2.3 lines, 2–4 hour task cycles (30 minutes in Ruby), cyclomatic complexity 1.8, and a one‑week boot camp returns productivity in 11 days by teaching pair programming and no getters and setters.
