Most law enforcing anti-corruption agencies have paper-based or computerized procedures that cover all aspects of investigation, including the investigation plan and tasks (which carries details of the case, background information, investigation scope and objectives, and resources), policy reviews on progress and tasks (and including any “approved” variations from original plans and tasks), an investigation report at the end of the investigation (including a summary, investigation process, findings, conclusion and recommendation, together with appropriately numbered documentation) and, after a court case or other sanction, a closure file. All investigators should complete an investigations diary (provided within the manual) of their actions based on the field book. The diary is later consolidated and becomes part of the case file.
