It helps you share out a maintenance budget that is always limited. ## How to rate it, simply Three factors, each scored from 1 to 5 and multiplied: - **Impact**: what happens if it fails. Does it stop the line? Does it affect safety? Does the customer notice? - **Frequency**: how often it fails, according to the history. - **Detectability**: whether you see the failure coming or it strikes without warning. The result ranks your assets. Those at the top of the list get serious [preventive](https://attendo.me/en/glossary/preventive-maintenance) work; those at the bottom, [corrective](https://attendo.me/en/glossary/corrective-maintenance). ## The usual mistake Doing the analysis once, saving it in a spreadsheet and never looking at it again. Criticality changes: a redundant machine stops being redundant when its twin breaks down, and a secondary machine becomes critical when what you produce changes. ## In attendo With [AI-CMMS](https://attendo.me/en/modules/ai-cmms), each corrective job gets a score from 0 to 100 that weighs asset criticality, impact, SLA risk and repeat failures. You set the weights, and a person reviews and decides. - [attendo CMMS](https://attendo.me/en/cmms) ## Where it is used in attendo ### Modules - [AI-CMMS](https://attendo.me/en/modules/ai-cmms): The AI in attendo CMMS: probable diagnosis and criticality - [AI Autopilot (Multiple AI Agents)](https://attendo.me/en/modules/ai-autopilot): Micro-agents that score and prioritize.

Maintenance ### Preventive maintenance PM Preventive maintenance is work planned by calendar or by usage to keep failures from happening: routine inspections, lubrication, scheduled replacements and regulatory checks. Maintenance ### MTBF Mean time between failures MTBF (mean time between failures) is the average time a piece of equipment runs properly between one breakdown and the next. It measures reliability. ### On the blog #### Asset inventory: where to start Every maintenance project starts with the inventory, and many get stuck there. Not because it is hard, but because it is tedious. And if it is done badly, everything that comes after inherits the problem. 3 min read [See all 53 glossary terms](https://attendo.me/en/glossary) ## Shall we look at it with your data?
