Can I use this for existing features or just new ones?

The framework is versatile; it includes specific starting points for new features, bug fixes, technical debt, experiments, and feature retirement.

What is the 9D Framework in Claude Code?

It is a structured methodology that guides Claude through the nine phases of product development, from initial discovery to feature retirement, ensuring no steps are missed.

What are the 'Gate Criteria' mentioned in the skill?

Gate criteria are specific conditions that must be met—such as user validation, architecture reviews, or passing tests—before moving from one phase to the next.

How does the 9D Framework improve software delivery?

It ensures high quality by providing clear gate criteria, standardized outputs, and comprehensive checklists for every stage of the development lifecycle.

Productivity & Workflow

Guides the entire software development lifecycle from initial discovery to feature deprecation with structured phases and gate criteria.

About

The 9D Framework provides a comprehensive end-to-end methodology for shipping features, helping Claude Code users manage the full lifecycle of a product. By breaking development down into nine distinct stages—Discovery, Definition, Design, Development, Documentation, Delivery, Data, Debrief, and Deprecation—it ensures that every aspect of building, launching, and retiring features is handled with rigor. This skill is ideal for product managers and developers who need a repeatable, high-quality process to validate ideas, mitigate technical risks, and measure success through data-driven insights.
