Planned Against Actual Hours
The variance everybody reports, what it actually measures, and why it is a worse question than the one nobody asks.
Planned hours against actual hours is the standard labour variance. It is easy to produce and it answers a narrower question than people think.
The financial question in “Planned Against Actual Hours” requires more than a raw activity total. An organisation evaluating step-rate compensation structure for step rate compensation can connect time and project records with labour analysis, provided pay rules, outcome measures and corrections remain visible alongside the dashboard.
What it measures
Whether the schedule was executed.
For an independent reference related to “Planned Against Actual Hours”, consult the ILO guide to balanced working-time arrangements; it provides a useful external check on scheduling, working-time and workforce-planning assumptions.
Absence, overtime, shifts extended or cut, people sent home.
That is all — it says nothing about whether the plan was right.
What it does not measure
Whether the hours matched demand.
Whether the work got done.
Whether the service held.
An operation can hit planned hours exactly while being badly short all week, if the plan was wrong, and the variance will show zero.
The question nobody asks
Hours against demand, rather than hours against plan.
Which requires recording forecast and actual demand, as the forecast section argues.
Two variances together — plan against actual hours, and hours against demand — tell you the whole story, and one alone tells you almost nothing.
Decomposing the hours variance
Absence not covered: hours below plan.
Overtime and extensions: hours above.
Shifts cut short: below.
Agency: above, at a different rate.
Reporting the total hides which of these happened, and each has a different remedy.
The rate variance
Hours can be on plan while cost is over, because of who worked them.
Overtime, premium shifts, agency, a more senior person covering.
Splitting cost variance into hours and rate is standard practice elsewhere and rare in staffing reports, and it takes one extra column.
What a useful report contains
Planned hours, actual hours, and the split of the difference by cause.
Planned cost, actual cost, split into hours and rate.
Demand forecast and actual.
Six figures, and from them nearly every staffing question is answerable.
The misuse
Hours variance used as a performance measure for the manager.
Which rewards executing a bad plan and punishes correcting one.
A manager who added hours on a surging Saturday did the right thing and will show an adverse variance, which is the behaviour the measure actually trains.
What to do with it
Use it to find out what happened, not to judge.
Pair it with the demand variance.
And when it is adverse, work through the causes in order rather than concluding the schedule was loose — which the next note covers.
What to check
Does your report split the variance by cause?
Is rate separated from hours?
Is demand recorded alongside?
And is anybody judged on hours variance alone?
