Preparing the incident and forensic report

The contents for reporting can come from a variety of sources and forms. Putting this all together along with preparing contemporaneous note-taking goes a long way to ensuring all the pertinent facts are captured and reported.

To round out the discussion on reporting, there are two additional subjects that impact the overall reporting process. These two topics, note-taking, and how to ensure the proper language is included in the report. Analysts should pay particular attention to these two topics as they have a direct bearing on the quality of the report and how it can be used.

Note-taking

Often overlooked, note-taking is a critical part of the analysis and reporting process. Failing to take proper notes contemporaneously with the analysis will make reconstructing the events with sufficient detail impossible or in some circumstances, analysts will need to repeat a process to capture the necessary data and artifacts.
