Sounds like you’re trying to build a playbook that’s both a solid framework and a living document. The trick is to lock down the core procedures that everyone must follow—things that reduce uncertainty and speed the response—while leaving clearly defined “switch points” where a team member can deviate if the data says it’s the right move. Keep the core in a shared folder, version‑control it, and annotate where you expect judgment calls. When the breach hits, run through the mandatory steps first, then hand over to the lead analyst to decide whether to pivot, all the while logging the decision so you can review it later. If you document the pivot, you’ll see whether the flexibility paid off or if the rigid part was more valuable. Stick to that loop and you’ll stay both disciplined and responsive.

Sounds like you’ve got the skeleton nailed. Just make sure the audit trail is as bulletproof as the core procedures, so you can tell when the flexibility was a good call or a wild goose chase. Iterate, test, repeat—until the playbook feels like an extension of your own reflexes, not a separate person.
