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
- •Define scope and estimation type (time/effort/complexity).
- •Load the estimation reference for structure.
- •Break into components and dependencies.
- •Add risks and confidence intervals.
- •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
