Which action is NOT a part of the 'How' in a report's basic elements?

The 'How' in a report typically refers to the methods and processes involved in gathering information and conducting analysis related to an incident. This includes detailing the methodologies applied to obtain data, describing the actions taken during an event, and noting the decisions that were made based on that information.

Revising previous reports, however, pertains to the assessment and modification of prior documentation rather than the current methods used in a specific report. It does not directly relate to how the incident was handled or how the information was collected and communicated in the present report. Therefore, it falls outside the 'How' category, which focuses on the current investigation process rather than the history of documentation.
