The team logged more hours this month, but the backlog barely moved. Throughput measures work completed in a defined period. Staff activity measures effort or actions, such as hours logged, calls made or tasks touched. Both can be useful, but they answer different questions.

Use throughput to understand what the process delivers. Use activity information to investigate how effort is being used. Neither figure, on its own, establishes the quality, difficulty or value of the completed work.
Define a comparable unit of completion
Choose a recognisable work item, such as an accepted client report or resolved request. Define the completion condition and reporting period. Avoid mixing a brief password reset with a complex implementation and treating each as equivalent output without explanation.
Where work varies substantially, group it into meaningful categories. Keep the classification simple enough to maintain and stable enough to compare over time.

Questions requiring a closer review of effort or waiting.
Read the measures together. Higher completions alongside more rejected work may signal a problem rather than an improvement.
An illustrative service week
A team logs 150 hours and completes 18 accepted requests. The following week it logs 155 hours and completes 12. These invented figures illustrate a question, not a productivity verdict.
The second week may contain more difficult requests, staff training or work waiting for client approval. Review a sample of cases and the change in work mix before drawing conclusions. Counting email replies would not resolve those differences.
Avoid turning a process measure into a personal league table
A throughput figure for a shared workflow includes dependencies beyond any one person's control. If people optimise for easy completions, complex or important cases may wait. Check ageing work and client outcomes alongside the count.
