About development-estimation
A development-estimation skill for breaking project scope into components, assessing risks, and producing effort, time, or complexity estimates with confidence intervals. It is intended for work with defined scope that needs a defensible breakdown.
Key features
- 01Scope and estimate-type definition
- 02Component and dependency breakdown
- 03Risk assessment and confidence intervals
- 04Assumptions and validation notes
Use cases
- 01Estimating feature or project effort
- 02Comparing complexity across components
- 03Communicating risks and estimate confidence

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

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
