Technical Knowledge
During a requirementsâgathering workshop for a new inventory system, the team needed clear definitions to avoid scope creep.
Explain to the client how functional and nonâfunctional requirements differ and why both are essential.
Described functional requirements as specific behaviors the system must perform (e.g., "track stock levels") and nonâfunctional requirements as quality attributes such as performance, security, and usability. Provided examples and documented them separately in the requirements matrix.
The client approved the distinction, leading to a wellâstructured requirements document that reduced change requests by 30% during development.
