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
