Start with the document you actually need, not the one you think you should produce
If you have a project in front of you right now and you need a BRD, the first decision is not what template to use. It is how much document this project actually warrants. In my experience, most BRDs produced by early and mid-career analysts are at least twice as long as they need to be. That is not because the analyst is being thorough. It is because they copied a heavyweight template and felt obliged to fill every section.
A simple business requirements document template is not a dumbed-down BRD. It is a disciplined one. It contains everything a reader needs to understand what is being built, why it is being built, and what success looks like. It contains nothing else. This article walks you through exactly what goes in, what stays out, and how to use this structure on a real project without losing credibility in the process.
What a simple BRD must contain
There are seven sections I include in every lightweight BRD regardless of project size or methodology. Everything else is optional and should only appear if it genuinely helps the reader make a decision or take an action.
- Project context and problem statement: One to three paragraphs explaining what situation has prompted this piece of work and what the business impact of doing nothing would be.
- Objectives: Three to five measurable outcomes the project must deliver, written in plain language, not aligned to any framework unless the organisation specifically requires it.
- Scope statement: A clear boundary that says what is in scope and, critically, what is out of scope. The out-of-scope list is often more valuable than the in-scope one because it prevents scope creep before it starts.
- Stakeholder summary: A short list of who is affected, who has authority to approve requirements, and who will be consulted. You do not need a full stakeholder analysis inside the BRD itself.
- Business requirements: The core of the document. Each requirement should be numbered, written in active voice, and tied to at least one objective. Aim for fifteen to thirty requirements on a typical small to medium project.
- Assumptions and constraints: Things you are taking as true without formal confirmation, and limitations (budget, timeline, technology, regulation) that will shape what solutions are viable.
- Approval and sign-off: A simple table listing who needs to approve the document, their role, and the date they signed. Without this, the BRD is a working draft forever.
What a simple BRD does not need
The following sections appear in many BRD templates. Most of them belong somewhere else in your project documentation, not inside the BRD itself. Removing them from your requirements document does not make you less professional. It makes the document more readable and more likely to get the attention it deserves.
| Section often found in heavyweight BRDs | Why it does not belong in a simple BRD | Where it belongs instead |
|---|---|---|
| Executive summary | Duplicates the problem statement and objectives you have already written | Business case or project charter |
| Detailed process maps | Process documentation is a separate artefact with its own audience | Business process documentation |
| Functional requirements | Functional requirements describe how the system behaves, not what the business needs | Functional requirements document or user stories |
| Non-functional requirements | Performance, security, and availability belong in a dedicated NFR register | NFR template or system requirements specification |
| Glossary | A glossary adds pages without adding requirements clarity on most small projects | Project wiki or shared glossary document |
| Risk register | Risk management is a project management responsibility, not a BA document | Project risk log maintained by the PM |
| Solution options analysis | Evaluating options belongs before the BRD in the business case phase | Business case or feasibility study |
If you are not sure whether to include something, ask yourself one question: will a stakeholder make a different decision about requirements based on this content? If the answer is no, cut it. For a deeper look at how functional requirements differ from business requirements, the article on BRD vs FRD covers the distinction in detail.
A worked example: Project X, a government document digitisation initiative
I was brought in as the BA on Project X, a digitisation initiative for a government agency that managed case files across multiple agencies. The as-is process was almost entirely paper-based. Files moved physically between offices, were photocopied multiple times for different recipients, and had no tracking capability. The problems were well understood: no audit trail, duplication of effort, proceedings dependent on the physical location of a file, and no ability to plan workloads because no one had visibility of what was in the system at any given time.
The project sponsor wanted a full BRD delivered in two weeks. The project team expected something substantial because the initiative spanned seven different stakeholder groups and had been workshopped extensively before I arrived. I had attended workshops with each group separately, run walkthroughs of the proposed future-state workflow, and come out with a clear picture of what was needed.
My instinct was to keep the BRD lean. The problem was well-understood, the objectives were agreed, and the stakeholder groups had already articulated their needs clearly during elicitation. A 40-page document would not have added clarity. It would have obscured it.
The friction came from the technical lead. He pushed back hard on the simple format, arguing that a project of this scale needed detailed process flows, a glossary of terms used by each agency group, and a full NFR section inside the BRD. His view was that without all of this, the development team would be flying blind. I understood his concern, but I held the line on structure. I agreed to produce separate supporting artefacts: a process flow document showing the digitised workflow, a shared glossary in the project wiki, and a dedicated NFR register. The BRD itself stayed focused on business requirements only.
The result was a 14-page document covering all seven stakeholder groups, 28 numbered business requirements tied to six project objectives, a scope boundary that explicitly excluded youth court processes from the initial release (which avoided a significant delivery risk), and a sign-off table that all parties approved within five working days. The technical lead later acknowledged that the separation of artefacts made it easier, not harder, for his team to work from the documents.
How to write requirements that are actually simple
The simplest BRD in the world fails if the requirements themselves are vague or untestable. Here is how I write requirements that stay lean but remain precise.
- Use active voice and name the actor: “The system shall” is a functional requirement. “Investigating officers must be able to upload files directly to a case record” is a business requirement. Name who does what.
- One requirement per statement: If you find yourself writing “and” in a requirement, split it into two. Compound requirements are a sign-off nightmare.
- Tie every requirement to an objective: Number your objectives. Reference the objective number against each requirement. This makes prioritisation and scope discussions far easier when something gets challenged.
- Write at the right level of detail: Business requirements describe what the business needs to achieve, not how a system achieves it. If you are describing screens, fields, or logic, you have slipped into functional requirements territory.
- Flag dependencies explicitly: If a requirement can only be met after another system, team, or external party delivers something, say so in the requirement itself. Do not bury it in the assumptions section where it will be missed.
Structuring sign-off on a simple BRD
One of the reasons BRDs grow fat is that analysts add more content hoping it will reduce sign-off challenges. In practice it does the opposite. Longer documents get read less carefully and challenged on details that are irrelevant to the actual business decisions being made.
On Project X, I scheduled a 60-minute review session with representatives from all seven stakeholder groups before formally distributing the BRD for sign-off. I walked through each objective and each requirement verbally, invited challenges in the room, and captured any agreed changes on the spot. By the time the document was distributed for formal approval, there were no surprises. Sign-off was a formality, not a negotiation.
The lesson I take from that project and from 25 years of doing this work is that a short document does not mean a weak document. Clarity is harder to achieve than volume. If you can express what a project needs in 15 pages rather than 40, you have done more analytical work, not less. The discipline of cutting is what separates a simple BRD that gets read and acted on from a comprehensive one that gets filed and ignored.
Frequently asked questions
What should a simple business requirements document include?
A simple BRD should include a problem statement, project objectives, a scope boundary, a stakeholder summary, numbered business requirements, assumptions and constraints, and a sign-off table. Anything beyond these seven sections should only be added if it directly helps stakeholders make a decision about requirements. Functional requirements, process maps, and risk registers belong in separate documents.
How long should a business requirements document be?
There is no fixed length, but most small to medium projects need between 10 and 20 pages. A simple BRD with 15 to 30 well-written requirements will serve most projects better than a 40-page document that dilutes the key decisions across unnecessary content. Length should be driven by the complexity of the requirements, not by the size of the template.
What is the difference between a business requirements document and a functional requirements document?
A BRD captures what the business needs to achieve expressed in business language, while a functional requirements document describes how a system or solution must behave to meet those needs. Business requirements belong in the BRD and are written from the perspective of business users and outcomes. Functional requirements are written for developers and testers and describe system behaviour in detail.
Can I use a simple BRD template for an agile project?
Yes, a lightweight BRD works well as a starting point even on agile projects because it captures the business context and objectives before the team breaks work into user stories. Some agile teams use a BRD as a discovery artefact that feeds the product backlog rather than a formal sign-off document. The key is agreeing with your team and sponsor how the document will be used before you write it.
How do I get stakeholders to approve a business requirements document quickly?
The most effective approach is to run a live review session with key stakeholders before distributing the document for formal sign-off. Walking through requirements verbally surfaces disagreements early and avoids the back-and-forth of email-based review cycles. Keeping the document short and focused also means stakeholders are more likely to read it carefully rather than skim it.
