5W and 1H Model

5W and 1H Model

This model is practical way to approach any type of investigation.

The investigator considers the following questions in relation to each aspect of the alleged conduct:

  • What happened?
  • Where did it happen?
  • Who was involved?
  • When did it occur?
  • Why did it occur?
  • How did it occur?

This simple approach is the foundation to any investigation. It is applied initially and progressively through the investigation process to identify key and respond to key issues. It is the foundation to planning the investigation, interviewing witnesses and persons of interest.
