Maintenance Analytics

Use these questions to prepare for the Kanoa Maintenance certification exam.

What do MTTA and MTTR measure?

MTTA is the time from creation to first response; MTTR is the time from starting work to completing it. See Response and Reliability KPIs.

One asset has a much lower MTBF than the rest. What does that suggest?

It fails more often, which makes it a candidate for more preventive maintenance or replacement. See Response and Reliability KPIs.

The Work Order Flow chart shows more work orders created than completed. What's happening?

The backlog is growing. See Backlog and Labor.

Preventive work orders keep showing up in the older Backlog Aging buckets. What does that mean?

Planned maintenance is being deferred, often to fight breakdowns. See Backlog and Labor.

Why are logged labor hours reported separately from time active and time to complete?

One measures work actually done, the other elapsed time. A work order open for days with little labor logged is waiting, not being worked. See Backlog and Labor.
