KPI hygiene for service desks
Most service desks do not lack charts. They lack shared sentences that explain what a chart is counting. KPI hygiene is the unglamorous work of writing those sentences before you invest in another visualisation layer.
Start with verbs, not colours
Ask each measure: what human action does this count? “Resolved” must say who declared resolution, which system status maps to it, and whether customer confirmation is required. If two supervisors answer differently, the chart is already political.
Separate volume from quality
Ticket counts and reopen rates often share a dashboard but not a story. Volume explains load; quality explains whether that load finished cleanly. Mixing them into a single “health index” usually hides the trade-off you need to discuss.
Write the exclusion list
Hygiene includes saying what does not count: spam, duplicate merges, vendor-owned tickets, or test records. Publish the exclusions next to the formula. Teams that skip this step invent private filters and then argue about the output.
Refresh rules belong on the scorecard
State how often a metric updates and who owns a break in the pipeline. Business analytics for service performance tracking collapses when nobody knows whether yesterday’s number is late, partial, or wrong.
If you want structured practice, Service Scorecard Fundamentals spends an entire module on definition hygiene with peer critique.
