summary
Argues concrete DPE wins: a build cache (Gradle/Maven) reuses task outputs to cut builds — demo shows ~70% local time saved — and remote cache + Docker/Kubernetes agents enable test distribution for parallel runs; Netflix cuts a 62‑minute test cycle to under 5 minutes, a tiny team gains ~44 engineering days/year, and Gradle’s dataset shows ~5,600 days saved in a month. Adds analytics via build scans, and ML using XGBoost for predictive test selection (pre‑merge only); tools and demos are operational and repeatable.
