## Pre and post checklists
Procedures and plans can carry a pre-check that must be complete before isolation begins and a post-check before the plan closes.
## Several people, one plan
Workers claim the rows they are working on, and everyone's screen updates live as the plan changes. A new permission controls who may execute in parallel — administrators grant it per role.
**Where to find it** · Role Permissions → Lockout plans → Multi-person execution.
