| Nuclear industry here. In the fanciest systems, checklists live in a computerized procedure system tied into the plant process computer, so the plant state and procedures can be kept in sync and mistakes can be avoided when the software can see if you didn’t actually do the step you were supposed to. A more conventional approach is a document management system and controlled binders in the control room with the latest procedures, often laminated so they can be marked up and wiped off. When working procedures on paper, we always use a circle-slash system for place-keeping: circle the step number when starting it, and slash through the circle when completed. Finally, key procedures should have a separate document documenting the bases of the procedure—-why key values were chosen or what other documents they were taken from or depend on. That document becomes the key in change management—-if a dependency changes, or you want to change the procedure, you can use the bases document to ensure side-effects are considered. Finally, procedures still have programmed regular reviews. |
Thanks too for the circle-slash system, I'm pinching that.
