Which method is used during system investigation?

• A. Unit testing
• B. Interviews
• C. Database normalization
• D. Patch management

Answer: (B)

Gathering information from people who use or manage the system is essential in system investigation, and interviews are the most suitable method for this. They let you talk directly with users, managers, and IT staff to uncover what works, what doesn’t, and what changes are needed. Through targeted questions and follow-ups, you capture requirements, current processes, pain points, and constraints, which guide the scope and design of the new system. Unit testing is used later to verify that individual components work as intended, not to discover requirements. Database normalization is a design technique for organizing data, and patch management deals with applying updates to software after deployment; neither is about gathering initial information during investigation.
