What Makes a Good Software Requirements Brief

Why the brief matters

The quality of quotes you receive is directly proportional to the quality of your brief. Vague briefs get padded quotes because developers factor in the uncertainty. Clear briefs get accurate quotes because the scope is understood.

A good brief saves you money twice: once in more accurate quoting, and again in fewer change requests during development.

What to include

1. Business context. What do you do? What problem are you trying to solve? Why now? This helps the development team understand the "why" behind the requirements.

2. Current state. What do you use today? What works? What doesn't? Are there existing systems that the new software needs to work with?

3. User types. List everyone who'll use the system. Internal staff, customers, administrators, external partners. What does each group need to do?

4. Core workflows. Describe the key processes step by step. "A customer places an order → warehouse receives notification → picker fulfills order → customer gets tracking number." This is the most important part of the brief.

5. Integration requirements. Which systems does this need to connect to? Accounting, CRM, payment processing, shipping, email? Be specific about what data flows where.

6. Priority levels. Must-have vs should-have vs nice-to-have. This lets developers propose a realistic v1 scope.

7. Budget range. Even a broad range is helpful. "$50K-$100K" tells the developer to propose a focused solution. "$200K-$300K" means a more comprehensive build is possible.

8. Timeline expectations. Any hard deadlines? Seasonal requirements? Events or launches that constrain the schedule?

What to leave out

• Technology choices: Don't specify "build this in React" unless you have a strong technical reason. Let the development team recommend the right technology.
• Implementation details: "The system should use a microservices architecture", this is a solution, not a requirement.
• Pixel-perfect designs: Wireframes are helpful. Full mockups at this stage are premature.
