SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Large epics often stay too vague, too big to estimate, and end up sliced horizontally or arbitrarily; this advisor guides product managers through INVEST validation, Humanizing Work patterns, and split evaluation so every story becomes a vertical, user-valued slice.

Core Features & Use Cases

  • Rigorous INVEST validation: Pre-split questions cover independence, negotiability, value, estimability, and testability so you only split meaningful work.
  • Sequential pattern application: Walks through workflow steps, CRUD, business rules, data variations, data entry methods, major effort, simple/complex, deferred performance, and spikes until a thin end-to-end slice surfaces.
  • Split evaluation with Cynefin awareness: Encourages identifying low-value work, equalizing story size, and adjusting to obvious/complicated, complex, or chaotic domains while defaulting to the workshop-facilitation protocol for guided interactions.
  • Use cases: Turning onboarding or reporting epics into sprint-ready stories, choosing the right split pattern for tricky admin workflows, and coaching backlog refinement sessions with the Humanizing Work methodology.

Quick Start

Ask the advisor to break down your epic by sharing its title, hypothesis, acceptance criteria, persona, and estimate so it can recommend the first vertical story slice.

FAQPage Schema
How do I break down a large epic into vertical user stories?

To break down a large epic into vertical user stories, you apply Humanizing Work splitting patterns like workflow steps or business rules to create thin end-to-end slices. This ensures every story delivers independent user value.

What is the INVEST validation check for backlog refinement?

The INVEST validation check for backlog refinement assesses if an epic is Independent, Negotiable, Valuable, Estimable, Small, and Testable. This pre-split process ensures you only break down meaningful work into actionable stories.

When should I use epic splitting patterns during sprint planning?

You should use epic splitting patterns during sprint planning when a single feature is too large or vague to estimate. Sequentially applying patterns like CRUD, data variations, or simple/complex surfaces a viable vertical slice.

What's the best way to slice an epic without creating horizontal layers?

The best way to slice an epic without horizontal layers is applying Richard Lawrence's patterns to extract thin end-to-end user value. Evaluating splits with Cynefin awareness helps equalize story size and remove low-value work.

What information do I need to provide to split an epic effectively?

To split an epic effectively you need to provide its title, hypothesis, acceptance criteria, persona, and estimate. Capturing this context enables the advisor to run sequential splitting patterns and recommend the first vertical slice.
