What is a project requirements document?

A project requirements document captures the business, functional, non-functional, stakeholder, constraint, dependency, and acceptance needs the project must satisfy.

What should be included in a project requirements document?

Include background, objectives, stakeholders, business requirements, functional requirements, non-functional requirements, constraints, dependencies, acceptance criteria, and approval notes.

Who writes project requirements?

Requirements are often drafted by a business analyst, product owner, project manager, delivery lead, or subject matter expert with input from stakeholders and users.

How is a requirements document different from a scope statement?

Requirements describe what the project needs to satisfy. A scope statement defines which work, deliverables, exclusions, constraints, and approval boundaries are included.

How do you keep requirements from changing constantly?

Clarify approval authority, define acceptance criteria, keep a change control process, and document why approved requirement changes affect scope, schedule, cost, or quality.

Project requirements document created before scope and delivery planning

Project Requirements Document Guide

By Dawid Oleksiuk ScrumbuissPublished July 2, 2026Editorial policy

A project requirements document captures what the project must satisfy before the team turns the work into scope, tasks, designs, or technical plans. It helps stakeholders agree on needs before the delivery team commits to a solution.

This guide targets the project requirements document keyword cluster found in SEMrush research. It supports scope and charter pages by explaining how requirements feed the approved project boundary.

Key Takeaways

A requirements document captures needs before detailed planning.
It should separate business requirements, functional requirements, constraints, and acceptance criteria.
Requirements should be testable enough to support review.
The document should be updated when approved changes alter the need or solution.

Requirements vs. Scope

Concept	Question answered
Requirements	What does the solution need to satisfy?
Scope statement	What work and deliverables are included or excluded?
Acceptance criteria	How will we know the requirement or deliverable is accepted?

Requirements should inform scope. They are not the same thing.
