Requirements Gathering

This Skill provides a professional and complete methodology for conducting requirements gathering that covers all business layers, not just "the app" or "the system."

Fundamental Principle

Requirements gathering is NOT just a list of functionalities.

Good requirements gathering covers all business layers:

• 🧠 Idea and objective
• 👥 Users
• 💼 Operation
• 💰 Money
• ⚙️ Technology
• ⚠️ Risks
• 📈 Growth
• 🔗 Traceability (from Business to Code)
• ⚖️ Quality Gates (Validation standards)

Available Methodologies

1. Design Thinking (for new ideas)

Ideal when:

• The idea is still being validated
• Not everything is clear
• You want to truly understand the user

Phases:

1. Empathize - Understand users
2. Define - Identify key problems
3. Ideate - Generate solutions
4. Prototype - Create early versions
5. Test - Validate with real users

Note: Used to discover what to build, not to document everything.

2. Business Analysis (BABOK)

The most complete and professional.

Covers:

• Business requirements
• Functional requirements
• Non-functional requirements
• Business rules
• Stakeholders
• Processes

Note: This is what's used to create formal documents.

3. Lean / Startup Canvas (quick vision)

Useful for:

• Organizing the idea
• Seeing if the business makes sense

⚠️ Important: DOES NOT replace complete requirements gathering.

Recommended Approach

Combine 3 key elements:

1. Business vision
2. Processes
3. System / product
4. Traceability & Validation (Ensure everything is connected and meets quality standards)

And document everything in a single master artifact or a structured layer system.

Structure of the Complete Requirements Document

📌 1. Business Vision

Include:

• Problem solved - What pain or need does it address?
• Value proposition - Why is it better than alternatives?
• Business objective - Clear and measurable goals
• Main KPIs - Success metrics
• Scope - What IS and what is NOT included

Format example:

## Business Vision

### Problem

[Description of the problem being solved]

### Value Proposition

[What makes this product/service unique]

### Objectives

- Objective 1: [Description]
- Objective 2: [Description]

### KPIs

- KPI 1: [Specific metric]
- KPI 2: [Specific metric]

### Scope

**Includes:**

- [Element 1]
- [Element 2]

**Does not include:**

- [Element 1]
- [Element 2]

📌 2. Stakeholders

Identify all involved actors:

• Business owners - Who makes decisions
• End users - Who will use the system
• Administrators - Who will manage the system
• Suppliers - External services or products
• Third parties - Payments, logistics, integrations, etc.

Suggested format:

## Stakeholders

| Type  | Name/Role | Interest          | Influence         |
| ----- | --------- | ----------------- | ----------------- |
| Owner | [Name]    | [High/Medium/Low] | [High/Medium/Low] |
| User  | [Type]    | [High/Medium/Low] | [High/Medium/Low] |

📌 3. User Types (Personas)

For each user type, document:

• What they need - Key functionalities
• What pain they have - Current problems
• What they expect from the system - Expectations

Example:

## Personas

### End Customer

- **Needs:** Make fast and secure purchases
- **Pain:** Complicated checkout processes
- **Expectation:** Checkout in less than 3 clicks

### Administrator

- **Needs:** Manage inventory and orders
- **Pain:** Lack of real-time visibility
- **Expectation:** Dashboard with updated metrics

📌 4. Business Processes

⚠️ VERY IMPORTANT - This is where many fail.

Document complete flows:

• How a customer enters
• How a sale is generated
• How payment is collected
• What happens if the payment fails
• How a claim is handled

Express as step-by-step flows:

## Process: Product Purchase

1. User browses catalog
2. User adds products to cart
3. User proceeds to checkout
4. System validates availability
5. User enters payment details
6. System processes payment
   - **If success:** Confirms order and sends email
   - **If failure:** Shows error and allows retry
7. System generates shipping order
8. User receives confirmation

For complex processes, see references/process-mapping.md.

📌 5. Functional Requirements

Standard format:

• FR-01: The system must allow...
• FR-02: The user will be able to...

Common categories:

• User registration
• Order management
• Payments
• Notifications
• Reports

Example:

## Functional Requirements

### Authentication

- **FR-01:** The system must allow registration with email and password
- **FR-02:** The system must send a verification email
- **FR-03:** The user will be able to recover a forgotten password

### Order Management

- **FR-04:** The user will be able to view order history
- **FR-05:** The system must allow canceling orders in "pending" status

📌 6. Non-Functional Requirements

This separates the amateur from the professional.

Key areas:

• Security - Authentication, authorization, encryption
• Performance - Response times, capacity
• Scalability - Expected growth
• Availability - Uptime, redundancy
• Legal compliance - GDPR, data protection
• UX / Usability - Accessibility, responsive

Example:

## Non-Functional Requirements

### Performance

- **NFR-01:** The system must respond in < 2 seconds for 95% of requests
- **NFR-02:** The system must support 1000 concurrent users

### Security

- **NFR-03:** All passwords must be hashed with bcrypt
- **NFR-04:** Communications must use HTTPS/TLS 1.3

### Compliance

- **NFR-05:** The system must comply with GDPR for European user data

📌 7. Business Rules

Domain-specific logic:

Examples:

## Business Rules

- **BR-01:** An order cannot be canceled after 30 minutes of creation
- **BR-02:** A user can only have one active plan at a time
- **BR-03:** Commissions are calculated as 5% of the total amount
- **BR-04:** Taxes are applied according to the buyer's region

📌 8. Data Model (High Level)

Conceptual, not SQL yet.

Document:

• Primary entities - User, Order, Product, etc.
• Relationships - One to many, many to many
• Critical data - Essential fields

Example:

## Data Model

### Primary Entities

**User**

- id (PK)
- email (unique)
- name
- registration_date

**Order**

- id (PK)
- user_id (FK)
- status
- total
- creation_date

**Product**

- id (PK)
- name
- price
- stock

### Relationships

- A User can have many Orders (1:N)
- An Order can contain many Products (N:M)

For complex models, see references/data-modeling.md.

📌 9. Integrations

Necessary external services:

• Payment gateways - Stripe, PayPal, etc.
• External APIs - Third-party services
• Third-party services - Email, SMS, analytics

Example:

## Integrations

### Payment Gateway

- **Provider:** Stripe
- **Functionality:** Credit card processing
- **Data exchanged:** Amount, currency, card token

### Email Service

- **Provider:** SendGrid
- **Functionality:** Sending notifications
- **Data exchanged:** Recipient, subject, HTML body

📌 10. Risks and Assumptions

Identify potential problems:

• Technical risks - Dependencies, scalability
• Legal risks - Compliance, privacy
• Business assumptions - Assumptions that must be validated

Example:

## Risks

### Technical

- **R-01:** Dependency on external API may cause downtime
  - _Mitigation:_ Implement caching and fallback system

### Legal

- **R-02:** Changes in data protection regulation
  - _Mitigation:_ Modular design for rapid adaptation

## Assumptions

- **S-01:** Users have stable internet access
- **S-02:** Initial volume will not exceed 10,000 users

📌 11. Roadmap / Phases

Divide into manageable stages:

Example:

## Roadmap

### MVP (Phase 1) - 3 months

- Registration and authentication
- Product catalog
- Shopping cart
- Basic payment with Stripe

### Phase 2 - 2 months

- Notifications system
- Order history
- Basic administration panel

### Phase 3 - 3 months

- Advanced reports
- Logistics integration
- Recommendations system

📌 12. Architecture Decision Records (ADR)

Document critical technical decisions to preserve context.

Example:

• ADR-001: Use PostgreSQL for relational data integrity.
• ADR-002: Implement Redis for real-time notification caching.

See references/adr-template.md for details.

📌 13. Traceability Matrix & Tags

Embed cumulative tags to bridge the gap between requirements and implementation.

Format: @brd: BRD.01.01 @req: REQ-001

See references/traceability-guide.md.

📌 14. Quality Gates & Score

Evaluate the maturity of the documentation before proceeding.

• Maturity Level: [0-100%]
• Status: [Draft | Ready for Dev | Approved]
• Missing Items: List of gaps to be filled.

Gathering Process (Step by Step)

0. Process Kickoff & Roadmap

Instruction: At the very beginning of the interaction, you MUST:

1. Introduce yourself: Briefly explain you are a Business Requirements Analyst using a professional methodology.
2. Present the Roadmap: Explain the 6 phases you will follow (Discovery → Vision → Processes → Functional/Non-Functional → Data Model → Roadmap) so the user knows what to expect.
3. Acknowledge Documentation: If the user has provided files or previous context, state that you will analyze them first to avoid asking for information already provided.

1. Discovery & Context Analysis (Smart Discovery)

Instruction:

• Analyze First: Before asking any questions, scan all provided files (images, text, documents).
• Find Gaps: Extract all possible information (Stakeholders, Problem, Goals) from the context.
• Zero Redundancy Rule: Never ask "What is the problem?" if it's already in the documents. Instead, validate: "I've analyzed the documents and understood the problem as [X]. Is that correct?".

2. Interviews & Deep Dive

Instruction: Focus only on the gaps. Even if you are the stakeholder yourself, perform the exercise of answering:

• What problem does this solve?
• Who will use it?
• How will they use it?
• What alternatives exist?
• Why is this better?

2. Uncomfortable Questions

Fundamental for discovering edge cases:

• What happens if the payment fails?
• What happens if the user loses connection?
• What happens if there is duplicate data?
• What happens if the external service is down?

3. Diagram Flows

Create visual diagrams of:

• User flows
• Business processes
• System architecture

4. Write → Validate → Adjust

Iterative process:

1. Write the first version of the document
2. Review with stakeholders
3. Identify gaps and ambiguities
4. Adjust and refine
5. Repeat until consensus is reached

5. Entity & Data Model Synthesis (Auto-ERD)

Instruction:

• Active Extraction: Throughout the entire process, identify all key entities mentioned (e.g., Orders, Users, inventory items).
• Auto-Generation: At the end of the analysis, if entities were detected, generate the Data Model section automatically.
• Visual Diagram: You MUST include a visual Entity-Relationship Diagram using Mermaid.js syntax for better clarity.

6. Living Document

Keep it updated:

• Use Markdown format for versioning
• Tools: Notion, Confluence, GitHub Wiki
• Update when requirements change

Complete Template

For a ready-to-use template, see assets/requirements-template.md.

Final Result

When you finish the complete gathering, you have:

• ✅ Document for development - Clear specifications
• ✅ Basis for quoting - Defined scope
• ✅ Guide for delegating - Complete instructions
• ✅ Material to present - To partners or investors

Important Tips

1. Don't start by writing requirements - Start by understanding the business as if it already existed
2. Be specific - "Fast" is not a requirement, "< 2 seconds" is
3. Include the "why" - Not just the "what," but the reason behind it
4. Document decisions - Why a certain technology or approach was chosen
5. Keep updated - An outdated document is worse than no document at all
