What problem does it solve?
HDD provides a structured methodology to diagnose root causes and validate hypotheses when outcomes are uncertain, guiding teams through a repeatable decision-making process before implementing changes.
Core Features & Use Cases
- Seven-step workflow: HT (Hypothesis Test), PT (Plan Test), AT Design (Acceptance Test Design), DEV (Development), AT Run (Acceptance Test Run), and E2E (End-to-End) to structure problem solving.
- Evidence-based decision making: formalizes hypotheses, priors, and verification paths to reduce guesswork.
- Use cases include debugging ambiguous defects, architecture and design decisions under uncertainty, and risk mitigation across product development.
Quick Start
Start HDD by outlining your uncertain problem, identify the hypothesis to test, and map a seven-step plan before coding.
