Business Requirements Document (BRD)
Part of the Business Analyst Roadmap
In short
Before anyone talks about screens or databases, someone has to write down why the project exists and what it must achieve. That document is the BRD, and sponsors actually read it.
A high-level document describing the business need, objectives, and scope of a project — written for stakeholders and sponsors, focused on 'why' and 'what', not implementation detail.
Think of it like this
The brief for your architect
When you build a house, you tell the architect why: parents are moving in, so you need a ground-floor bedroom, two parking spots and a budget limit. You don't draw the beams. The BRD is that brief: the why and what, not the how.
Watch it happen
What goes inside a BRD
1/5A BRD is written for sponsors and business leaders. It answers 'why are we doing this and what must it achieve?'
The big ideas
What you need to know
Why before what
Start with the business problem and measurable goals. Every later requirement should trace back to one of them.
Scope protects you
An 'out of scope' list stops arguments later when someone says 'I assumed this was included'.
Written for business readers
Plain language, no technical design. A sponsor should understand it in one sitting.
Assumptions and constraints
Note what you're assuming (staff have tablets) and limits (budget, deadline, regulations). These often cause trouble later.
Save yourself the pain
Common mistakes
Oops
Filling the BRD with screen layouts and database fields.
Do this instead
Keep it at the business level. Put system behaviour in the FRD or user stories.
Oops
Writing goals like 'improve customer experience'.
Do this instead
Make them measurable: 'Reduce complaint calls about refunds by half within six months'.
Your mission
Draft a one-page BRD
Quick check
Which line belongs in a BRD rather than an FRD?
Go deeper
- 1Find 2-3 public BRD templates and compare their structure.
- 2Write a full BRD for a small, real or hypothetical project idea.
- 3Learn to separate business objectives from solution-specific detail, which belongs in an FRD.
