pert-estimation

What problem does it solve?

PERT-based effort estimation provides defensible, variance-aware sizing for QA initiatives by combining optimistic, most-likely, and pessimistic inputs with tier- and phase-based breakdowns. It enables explicit assumptions and structured outputs suitable for governance and client proposals.

Core Features & Use Cases

• Variance-aware estimation using the PERT formula (O, M, P) with computed E and σ.
• Tier and complexity categorization with phase allocation to ensure realistic effort planning.
• Composable sub-skill usage within estimation-sizing-thinking to deliver sizing detail when needed.
• Structured outputs: scope summary, test-case table, phase breakdown, assumptions, and confidence qualifiers.

Quick Start

Provide baseline O, M, P for the target test tiers and project phases to generate an E ± σ range and a full phase breakdown.
