Briefing and Debriefing
Operations — Authorised Professional Practice
Summary
This section of the Authorised Professional Practice (APP) outlines the processes of briefing and debriefing within police operations. Briefing prepares police personnel for an operation by providing essential information and guidance, while debriefing identifies lessons learned to enhance future efficiency. Key components of these processes include the structure and objectives of briefings, the use of the IIMARCH model for effective communication, and ensuring media staff receive appropriate instructions. The debriefing stage focuses on organizational learning and incorporates insights from all personnel and partner agencies involved in the incident. A structured approach is recommended to secure a thorough documentation trail for audits and disclosures.
