Collect Requirements

Determines, documents, and manages stakeholder needs and requirements to meet objectives, producing the requirements documentation and traceability matrix. Get this wrong and everything downstream is built on sand.

This process turns stakeholder needs into clear, documented requirements. The team uses elicitation techniques — interviews, workshops, prototypes, observation — to surface what stakeholders actually need, not just what they first ask for, then documents, prioritizes, and traces it back to objectives.

Collect Requirements: key inputs and outputs
The key inputs feeding Collect Requirements and the deliverables it produces — full ITTOs are listed below.

The traceability matrix links each requirement to its source and to the deliverables that satisfy it, which is what makes scope verifiable later. The hard part is reconciling conflicting requirements and separating genuine needs from wishes.

Common pitfalls. Accepting the first stated requirement without probing the real need; missing stakeholders and therefore requirements; ambiguous, untestable requirements; and no traceability, so no one can prove the product meets what was agreed.
