A matrix usually tells you what needs to be inspected and how often, but not what the inspector actually checks, which often depends on the experience of whoever does it. That makes results inconsistent between inspectors and hard to compare over time.
The matrix is still a good starting point, since it already lists the equipment types and inspection types. From there, each combination needs a checklist of specific checks with clear pass or fail criteria, usually built from the relevant standards, OEM requirements and the knowledge of your most experienced inspectors, and AI can draft these for review rather than starting from a blank page.
