SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Decompose large epics into standard sub-items to enable scoped planning and execution.

Core Features & Use Cases

  • Domain-concern based decomposition that yields independently validatable work items.
  • Goldilocks sizing guidance (trivial, standard, epic) to determine when decomposition is required.
  • Clear epic-to-WI workflow guidance with links to backlog, spec-model, and onboard processes.

Quick Start

Describe an epic at a high level and initiate its decomposition into standard sub-items.

FAQPage Schema
How do I decompose large epics into actionable work items for scoped planning?

Decompose large epics by applying domain-concern based breakdown to yield independently validatable work items. This enforces an epic-file structure and provides clear success criteria to guide project governance through spec, design, plan, and implement stages.

When should I decompose an epic versus leaving it as a single backlog item?

Use Goldilocks sizing guidance to classify work items as trivial, standard, or epic. Decomposition is required when an item reaches epic scale, ensuring it is broken down into standard sub-items for scoped planning and execution.

How does agile epic decomposition help with backlog sizing decisions?

Agile epic decomposition helps backlog sizing by applying Goldilocks sizing rules to identify oversized work items. It turns large domain concerns into standard sized sub-items, enabling accurate planning and clear item sequencing.

Can I turn domain concerns into independently validatable work items for sprint planning?

Yes, you can turn domain concerns into independently validatable work items by applying structured epic decomposition. This process yields standard sub-items with clear success criteria that move directly through spec, design, plan, and implement stages.

What is the best way to structure an epic file for agile backlog decomposition?

The best way to structure an epic file is to enforce a standardized format that captures domain concerns, clear success criteria, and item sequencing. This structure guides the breakdown into standard sub-items and links directly to backlog and spec-model processes.

Does epic decomposition work for scaling agile work items across spec and design stages?

Yes, epic decomposition works for scaling agile work items by breaking large epics into standard sub-items that move sequentially through spec, design, plan, and implement stages. This provides clear project governance and scoped execution.
