- Follow-up actions
This process helps maintain accountability and continuous improvement in investigative work.
Understanding the 5 Why Investigation Method
The 5 Why investigation method is a simple yet powerful technique used to identify the root cause of a problem by asking “Why?” five times in succession. For example:
- Why did the incident happen?
- Why was the procedure not followed?
- Why was the training insufficient?
This method is taught in our courses to help investigators dig deeper beyond surface answers.
Three Common Methods of Investigation
The three primary methods of investigation you will learn include:
- Direct Investigation: Gathering evidence firsthand through observation and interviews.
- Indirect Investigation: Analyzing reports, records, or third-party information.
- Technical Investigation: Using technology like forensic tools, databases, or cyber analysis.
Each method plays a role in solving different types of cases.
