Explanation
The team that is responsible for determining how the impact of the incident is managed within the policy guidelines set by the strategic team is the tactical team. The tactical team is composed of managers or experts who have the authority and competence to make decisions and allocate resources to implement the business continuity plans and strategies. The tactical team coordinates and communicates with the operational team, which is responsible for executing the recovery and restoration activities, and reports to the strategic team, which is responsible for setting the overall direction and objectives of the incident response1.
