What does a thorough case folder help prevent in terms of an investigation?

A thorough case folder is essential in an investigation because it systematically organizes all information, evidence, and documentation related to the case, which helps prevent the duplication of work. When investigators have access to a well-maintained case folder, they can easily track what has already been done, what evidence has been collected, and what information has been recorded. This reduces the likelihood of multiple team members conducting the same interviews or collecting the same evidence, which not only saves time but also ensures that resources are used efficiently.

Additionally, a thorough case folder facilitates continuity of knowledge; any personnel involved in the investigation can quickly get up to speed by reviewing the organized documentation. This clarity and organization foster effective collaboration among team members and prevent the unnecessary repeat of processes, leading to a more streamlined and efficient investigative effort.
