• Modeling business processes with BPMN

• Creating functional specifications

• Analyzing stakeholder needs

• Defining product requirements documents (PRDs)

Quick Start

Invoke this skill when:

• Gathering and documenting requirements

• Writing user stories and acceptance criteria

• Modeling business processes with BPMN

• Creating functional specifications

• Translating business needs to technical specs

Do NOT invoke when:

• Designing system architecture (use solution-architect)

• Defining product strategy (use product-manager)

Decision Framework

Requirements Type: ├── New feature → User stories + acceptance criteria ├── Process improvement → AS-IS/TO-BE BPMN models ├── System integration → Interface specifications ├── Compliance need → Regulatory requirements matrix └── Stakeholder request → Impact analysis + prioritization

Core Workflows

1. Requirements Gathering

• Identify all stakeholders

• Conduct discovery interviews

• Document current pain points

• Define success metrics

• Draft initial requirements

• Validate with stakeholders

• Prioritize using MoSCoW or similar

2. User Story Creation

• Identify user personas

• Map user journeys

• Write stories in standard format

• Define acceptance criteria (Given/When/Then)

• Estimate complexity with team

• Refine through backlog grooming

3. Business Process Modeling

• Map current state (AS-IS) process

• Identify bottlenecks and pain points

• Design future state (TO-BE) process

• Define transition requirements

• Create RACI matrix for roles

• Document process metrics

Best Practices

• Use standard user story format: "As a [user], I want [goal], so that [benefit]"

• Write testable acceptance criteria

• Maintain requirements traceability matrix

• Validate requirements with real users

• Keep documentation living and updated

• Use visual models to communicate complex processes

Anti-Patterns

Anti-Pattern Problem Correct Approach

Solution in requirements Constrains implementation Focus on the "what", not "how"

Missing acceptance criteria Unclear definition of done Every story needs testable criteria

No stakeholder validation Building wrong thing Regular stakeholder reviews

Waterfall requirements Can't adapt to change Iterative refinement

Technical jargon Business can't validate Use business language
