The Schedule-to-Time Join
The first join in the chain. What the rota sends, what the clock sends back, and the four ways they disagree.
Analysis
The joins
Four boundaries in a standard chain, five where agency workers exist. Each has a payload, a mechanism, a failure mode and an owner.
10 notes
The Time-to-Payroll Join
The join where errors become money. What crosses it, what must not, and the reconciliation almost nobody runs.
Analysis
The Absence Join
Absence explains the gap between scheduled and worked, and it usually lives in a system that knows nothing about shifts.
Analysis
The Forecast Join
Demand becomes a staffing requirement through a ratio nobody owns, and that ratio decides more than the forecast does.
Analysis
Which System Owns Which Rule
Overtime calculated in two places is the classic workforce management defect. A register that prevents it takes an afternoon.
Procedure
How the Data Actually Moves
Files, APIs and manual export. What each fails at, and why the choice matters less than the failure handling.
Reference
Four Systems, Four Clocks
Each module works on a different time horizon, and the mismatch between them is a failure mode in its own right.
Analysis
More Than One Country
One chain, several legal regimes. Where to put the variation, and the two designs that both fail.
Analysis
Agency and Contingent Workers
People who work in your operation and are paid by someone else. A fifth path through the chain that most implementations forget.
Analysis
When Payroll Is Outsourced
The commonest arrangement of all, and the one where the most important join crosses an organisational boundary as well as a technical one.
