What constitutes an 'investigation plan' and who should approve it?

• A. A checklist of actions to be performed daily.
• B. A memo describing only the incident summary with no data collection plan.
• C. A document outlining scope, roles, data collection methods, timeline, and expected outcomes; approved by management or safety leadership.
• D. An informal note written by the investigator with no formal approval process.

Answer: (C)

A formal investigation plan is a documented blueprint that defines how the investigation will be conducted. It lays out the scope and objectives, the data collection methods to be used (such as interviews, document reviews, and observations), who is responsible for each task, the timeline with milestones, and the expected outcomes or deliverables. Clear structure like this keeps the investigation focused, repeatable, and defensible. Approval by management or safety leadership is essential because it authorizes the plan, ensures resources are available, and confirms alignment with organizational policies and any regulatory or compliance requirements. This top-level sign-off provides accountability and sets expectations for what will be investigated and how. This matches why the best answer includes scope, roles, data collection methods, timeline, and expected outcomes, with formal approval. The other options fall short because they lack essential investigative elements: a simple daily-action checklist is operational, not an investigation plan; a memo that only summarizes the incident provides no data collection or analysis plan; and an informal note with no formal approval lacks authority and a structured process.
