ReqBrief for Software Agencies: Requirements Before You Estimate

Bad estimates start with unclear requirements. Get them out of the client before anyone touches a story point.

In software, a vague requirement is an expensive one. The integration nobody mentioned, the user role that surfaces in week three, the "obviously it should also do X" — each one detonates the estimate and the timeline.

ReqBrief runs a structured requirements interview before estimation. It asks the client about the core problem, the users and roles, the must-have integrations, the data and the constraints, and returns a brief your team can scope and point against.

The pains we hear most

Hidden integrations

The third-party system nobody mentioned until mid-build.

Unclear users and roles

Who actually uses this, and what can each role do?

Blown estimates

Story points based on assumptions, not requirements.

Moving goalposts

"It should obviously also..." arriving after sign-off.

How ReqBrief helps

Requirements first

Scope, users, integrations and constraints captured before estimation.

Fewer nasty surprises

The interview surfaces the things clients forget to mention.

Estimates you can defend

Point against a real brief, not a hopeful guess.

A shared source of truth

One brief for the client, PM and engineers.

What it looks like

A dev shop is asked to "build an internal tool." Before estimating, they send a ReqBrief link. The interview surfaces the three systems it must integrate with, the four user roles, the reporting the client assumed was included, and the compliance constraint nobody had raised. The estimate goes out grounded in reality — and survives contact with the project.

FAQ

Can it capture technical detail like integrations and roles?

Yes. With the project context set, the interview probes for integrations, user roles, data and constraints — the details that most often break software estimates when missed.

Does it replace a full requirements/discovery phase?

It is not a substitute for deep technical discovery on complex builds, but it front-loads the requirement gathering so discovery starts from a structured brief instead of a blank page.
