This Requirements Documentation Software Development document shows how Eduardo Montes and Henry Douglas captured, organized, and baselined the complete requirements for the ProjectAdm SaaS platform — covering functional requirements, non-functional requirements, business rules, and the traceability links that connect each requirement to its originating stakeholder need and downstream WBS deliverable. This fully completed example demonstrates how requirements documentation supports both Agile backlog management and traditional scope control in a hybrid project environment.

What Is Requirements Documentation?

Requirements Documentation is a PMBOK 8 output in the Planning Performance Domain that describes how individual requirements meet the business need associated with the project. It captures stakeholder needs in specific, measurable, traceable terms — distinguishing between business requirements (what the business needs), stakeholder requirements (what specific stakeholders need), solution requirements (functional and non-functional), transition requirements, and project requirements. In hybrid software projects, requirements documentation bridges the gap between the Agile user story backlog and the formal acceptance criteria needed for milestone gate reviews and contractual deliverable acceptance.

What This Requirements Documentation Software Development Includes

The ProjectAdm Requirements Documentation covers the complete requirements baseline for the SaaS platform:

• Business Requirements (BR) — BR-001: Platform must support multi-tenant isolation with zero cross-tenant data exposure; BR-002: Platform must generate recurring SaaS revenue through 4 subscription tiers (Free, Starter, Professional, Enterprise); BR-003: Platform must be production-ready by February 28, 2026 to meet committed marketing launch date
• Functional Requirements — Core (FR) — FR-001: User authentication (email/password + Google OAuth + SSO for Enterprise); FR-002: Project CRUD with role-based access (Owner, Admin, Member, Viewer); FR-003: Kanban board with drag-and-drop (HTML5 Drag and Drop API); FR-004: Gantt chart with task dependencies and drag-to-reschedule (CR-002); FR-005: WBS view with 3-level hierarchy (CR-004); FR-006: AI task suggestions powered by OpenAI API (Sprint 20+)
• Non-Functional Requirements (NFR) — NFR-001: p95 response time <300ms for all primary user actions under 500 concurrent users; NFR-002: 99.9% monthly uptime SLA; NFR-003: WCAG 2.1 AA accessibility compliance; NFR-004: LGPD-compliant data handling for Brazilian users; NFR-005: Multi-language support (English + Portuguese at launch; Spanish post-launch ISS-005)
• Payment and Billing Requirements — PAY-001: Stripe integration for card payments (Visa, Mastercard, Amex); PAY-002: PayPal integration for PayPal balance and PayPal card; PAY-003: Webhook idempotency for all payment events (ISS-004 lesson); PAY-004: Automated subscription lifecycle (trial, active, past-due, cancelled); PagSeguro explicitly excluded (CR-003)
• Quality Requirements — QA-001: 100% PHPUnit test pass rate across all 321 tests before each milestone acceptance; QA-002: Zero critical security findings in pre-launch penetration test; QA-003: Code review mandatory for all PRs (minimum 1 reviewer); QA-004: Definition of Done enforced for all sprint stories (includes unit test, code review, and QA sign-off)
• Requirements Traceability — Each requirement traced to: originating stakeholder (Henry Douglas as PO for all FR; Eduardo Montes for PM-specific NFRs; CFO for billing requirements); WBS package (FR-001 → WBS 1.2; FR-003 → WBS 1.4; FR-004 → WBS 1.7); acceptance test ID in Lucas Park's test suite
• Requirements Baseline — Requirements baseline v1.0 approved January 28, 2025; updated 4 times via change requests (CR-001 through CR-004); current version v1.4 post-M4; 156 total requirements (142 functional, 14 non-functional)

How Eduardo Montes Used This Requirements Documentation Software Development

Eduardo Montes and Henry Douglas co-authored this Requirements Documentation Software Development document during Sprints 1–2, using a collaborative requirements workshop with all seven team members. The traceability matrix proved essential when Lucas Park needed to update the PHPUnit test suite after CR-002 added the Gantt chart: he could identify exactly which test IDs were affected by the new requirements (FR-004) without reviewing the entire test suite. The non-functional requirements (especially NFR-001 at 300ms p95) became the objective criteria that drove the ISS-002 rejection and rework decision at M3.

How to Use This Requirements Documentation Software Development Document

Use this example to understand how to structure Requirements Documentation Software Development that supports both Agile sprint execution and formal milestone acceptance. The key is making every requirement testable — "p95 response time <300ms" is testable; "the system should be fast" is not. Invest in measurable NFRs early, as they will drive the most critical acceptance decisions throughout the project.
