MSEL (master scenario events list): definition and structure
What is an MSEL?
MSEL stands for master scenario events list. It is the facilitator’s script: the ordered list of all injects that are fed in during an exercise to move the scenario forward.
Structure of an MSEL
Each entry (inject) usually contains:
- Timing: when the event is fed in.
- Event: the information or change of situation for the participants.
- Exercise objective: which capability is tested.
- Expected response: what the assessment is measured against.
- Responsible role: who should respond.
Why the MSEL matters so much
Without an MSEL an exercise becomes arbitrary. With it, all learning objectives are covered, and every response can be assessed objectively because it is compared with the expected response. The MSEL is therefore the basis for writing a meaningful after-action report after the exercise.
The MSEL in SecDrills
In a tabletop exercise with SecDrills the injects are already prepared. You do not have to write your own MSEL. The platform steers the process and documents every response automatically.
Frequently asked questions
What is an MSEL?
An MSEL (master scenario events list) is the script of an exercise: the ordered list of all planned events (injects) with timing, exercise objective and expected response. It ensures that all learning objectives are covered and documented in a traceable way.
What is in an MSEL?
Per inject it typically contains the timing, a description of the event, the exercise objective, the expected response and the responsible role. That makes the exercise controllable and allows an objective evaluation afterwards.
