# Development Estimation ## Overview Create consistent, defensible estimates by breaking scope into components, identifying risks, and providing confidence intervals. ## When to Use - Estimating feature or project scope - Providing effort or complexity estimates - Delivering risk-aware breakdowns Avoid when: - The task is trivial or a rough gut-check is sufficient - Requirements are unknown and need discovery first ## Quick Reference | Task | Load reference | | --- | --- | | Estimation workflow | `skills/development-estimation/references/estimate.md` | ## Workflow 1. Define scope and estimation type (time/effort/complexity). 2. Load the estimation reference for structure. 3. Break into components and dependencies. 4. Add risks and confidence intervals. 5. Deliver estimate with assumptions. ## Output - Estimate with breakdown and confidence interval - Assumptions, risks, and validation notes ## Common Mistakes - Estimating without clear scope - Ignoring risk and dependency factors - Overstating precision beyond available data
