Maximo KPI Guide: Mean Time To Repair (MTTR)

Most organizations measure MTTR wrong. Not because the formula is complicated. It is not. They measure it wrong because they never decided what ACTSTART means in their environment, never built the validation rules to enforce data entry, and never defined what happens when the number goes from Green to Yellow to Red. They end up with a number on a dashboard that nobody trusts, nobody acts on, and nobody can explain when leadership asks why it changed.

What You Get

This guide fixes all of that in one document. It walks you through the complete Maximo implementation for MTTR, starting with the definition (three calculation versions, including Mean Downtime as a companion metric for Availability), moving through the rules and filters that keep the data clean, and ending with the drilldown playbooks and root cause protocols that turn a number into action. Along the way, you get verified Maximo field mappings for every object involved, a step-by-step KPI Manager configuration walkthrough, a five-component Cognos Analytics report design with MDT companion view, six annotated SQL queries you can run against your database today, a Green/Yellow/Red threshold framework with a trigger-action matrix that names who does what by when, and seven root cause playbooks covering the specific failure modes I keep seeing drive MTTR up across organizations.

Who This Is For

This is for maintenance managers who need to report repair performance and know what levers to pull when it degrades. It is for reliability engineers who need MTTR and MDT to feed the Availability equation. It is for planners and schedulers whose kitting, staging, and scheduling discipline directly drives the number. It is for Maximo administrators who need the exact field names, validation rules, and KPI Manager configuration. And it is for consultants implementing Maximo who want a reference that gives them actual SQL and actual configuration steps instead of a theory overview.

Not a 5-Page PDF

This is not a 5-page PDF with a formula and a bar chart. It is a 100-page operational control guide with a 14-step quick setup checklist you can hand to your Maximo admin and say "do this Monday morning." It takes you from "I need to measure MTTR" to "I have ownership, thresholds, escalation rules, automated reports, and a weekly review process."
