Unclear requirements are the most expensive source of errors in projects. A defect hidden in a requirement is carried through development, testing and operation and becomes more expensive to fix the later it surfaces. Requirements management turns ideas into verifiable statements that everyone involved understands the same way.
Why requirements are almost always too vague
Subject matter experts describe what they want in their own language, with their knowledge in mind. Terms like fast, user-friendly or as before sound clear but mean something different to everyone. The task of business analysis is to close this gap: ask, refine, collect examples.
What makes a requirement testable
A good requirement is unambiguous, complete, verifiable and traceable. Instead of “search should be fast” it says: “search returns results within two seconds for up to 10,000 records.” In agile teams, acceptance criteria for each user story take this role; a concrete example in Given, When, Then format is often clearer than any abstract wording.
Eliciting, organising and keeping current
Requirements come from interviews, workshops, observing work, and analysing existing documents and systems. They are then organised, for example by business area, and prioritised, for instance with MoSCoW into must, should, could and won’t for now. Crucially, they do not freeze after approval: changes go through a clear process that assesses effort and impact.
The mistake that sinks projects
The most common mistake is not a badly worded requirement but a forgotten stakeholder. Not asking accounting, information security or front-line users leads to a solution that does not fit somewhere nobody considered. The first question is therefore who has requirements at all.
Requirements in regulated environments
In public administration, finance or medical devices, requirements must be traceable from the legal provision through the requirement to the test case. Leutrim Miftaraj works according to IREB on mandates for Swiss federal agencies and federally related companies, where requirement catalogues for formal acceptance by the client are standard.
Start with the next project
A simple start: list stakeholders, describe key processes with examples, and write a verification criterion for every requirement. More is in our article on stakeholder management; the approach is described in our offer on requirements analysis and engineering, and the term in the glossary entry on requirements engineering.
