Which investigation type follows the initial one?

• A. Secondary
• B. Primary
• C. Formal
• D. Informal

Answer: (A)

In a staged investigation process, you start with an initial inquiry to quickly establish what happened and gather basic facts. The next step is a secondary investigation, which is more thorough and broader in scope. It digs deeper by collecting additional evidence, re-interviewing witnesses if needed, reviewing logs and procedures, and cross-checking findings from the initial inquiry. This sequencing helps ensure reliability, avoids premature conclusions, and supports solid corrective actions. The other terms describe how the investigation is conducted (formal vs informal) or denote the main assessment itself rather than its follow-on phase, so they don’t fit the natural order after the initial inquiry.
