# Phase 4: Development Planning ## Where Blueprint Becomes Roadmap --- ## Welcome to the Planning Phase Amazing work! You've completed architecture and design—the creative heavy lifting. Now comes the practical work of planning how to build it. This phase is where beautiful architecture becomes actionable tasks. Where "we'll use microservices" becomes "Sprint 1: Build user service (13 points, 2 developers)." Where "security first" becomes "SAST scan in every build, DAST scan before release." **Here's what you'll walk away with:** A detailed work breakdown structure (every feature, every task) Resource plan with the right people in the right roles Risk register with mitigation strategies Quality and test plan with coverage targets CI/CD pipeline that automates build, test, and deploy Sprint 0 completed: environments ready, team onboarded A development team ready to start coding on Day 1 **Time investment**: 4-6 weeks (short but intense—this is where planning pays off) --- ## What This Phase Feels Like (A Real Story) I worked with a team that skipped detailed planning. They had great architecture, but jumped straight into coding. Three months in: - **Sprint commitments were missed** (tasks were bigger than estimated) - **Bottlenecks emerged** (everyone needed the backend dev) - **Quality suffered** (no time for testing, everything was urgent) - **Team burned out** (constant pressure, unclear priorities) They spent 2 months replanning while partially built cod
