What Do Drill Plans Do?

Drill plans play a core role in chaos drill management. They not only help engineers systematically schedule drill tasks for various failure modes but also trace and manage the drill task progress at any time. This ensures that failure modes are effectively verified through drills.

In specific operations, when creating drill plans, it is necessary to clearly specify the executor and the scheduled execution time, forming a standard basis for task allocation. After the executor confirms the task by accepting it, the system automatically generates the corresponding drill task. This task must accurately associate the predefined failure modes with the specific application regions. This ensures a high degree of alignment between the drill scenarios and actual business scenarios, providing strong support for evaluating the drill effectiveness and optimizing subsequent processes.

Drill plans encompass the entire lifecycle of the chaos drill.

• In the initiation phase, by analyzing business priorities, historical failure data, and risk assessment results, drill managers can systematically schedule drill tasks for high-impact, frequent failure modes on a tiered and periodic basis. This avoids the waste of drill resources and the omission of key scenarios.
• In the execution phase, the system traces the task startup status, execution progress, and completion of key nodes (such as fault injection, emergency response, and fault rectification) in real time. The system also provides early warning alerts for delayed tasks and coordination of executors. The whole drill process is effectively managed to ensure that each drill action is implemented as planned.
• Through standard drill plans, failure modes can be effectively verified through the complete drill loop of simulated scenarios, actual actions, post-action review. This process verifies the feasibility of contingency plans and the team's capabilities to handle emergencies.
