What else gets measured
Idle time, activity, location and productivity scores — what each measures and what it is read as.
Idle Time Measures Input, Not Work
What an idle-time counter actually measures, the four ordinary activities it cannot distinguish from absence, and why it is the weakest evidence in this collection.
Activity Monitoring and What It Sees
The five levels of activity monitoring, what each captures beyond its target, and the obligations that arrive with material nobody meant to collect.
Location, and the Distance to a Conclusion
What location data establishes, the three inferences stacked on top of it, and why vehicle tracking and person tracking are different propositions.
Productivity Scores as Evidence
What a productivity score is made of, why nobody in the organisation can usually describe the formula, and the two conditions for using one at all.
Notice, and What People Should Be Told
The seven things a monitoring notice has to contain, why the notice is also a design document, and what to do about systems that were installed without one.
Output Figures, and Where They Mislead
Why output is better evidence than activity and still misleads, the four adjustments that make a figure comparable, and what to check before using one.
The Measure That Changes the Work
Why any measure people are judged on reshapes the work it measures, the four forms that reshaping takes, and how to design a measure that survives being known.
Aggregate Reporting Without Individual Surveillance
Most monitoring questions are about an operation rather than a person: how to answer them in aggregate, and how to keep individual access for when there is a reason.
