B. Failure themes
Volume isn't the same as PM opportunity
The biggest failure category — power boards — is mostly damage and manufacturing, which a schedule can't prevent. The real preventative candidates are lower-volume but overwhelmingly wear-driven.
Tickets by component (all time)
Sorted by raw count. Color shows whether the component is a PM target.
- PM-addressable (in scope)
- Secondary candidate
- Not a PM target
Only ~26% of tickets are component-tagged, so these counts are a floor.
The opportunity map
X = % of a component's tickets tagged as wear or calibration (PM-addressable). Y = total ticket volume. Top-right is where a schedule pays off. Power board is high volume but low addressability. Wheels and load cells sit further right.
Bubble size mirrors ticket volume. Hover a bubble for details.
Top causes
Only two of the top causes — normal wear and calibration — are things a schedule can prevent. Everything else is damage, manufacturing, or software.
- PM-addressable
- Not addressable by schedule
Sub-component tags — what the ticket text actually mentions
Freshdesk sub-component tags (finer-grained than the component roll-up). Hall Effect Sensor and Swivel castor wheel are the two wear stories to watch.
