Effective FTE and output-equivalent FTE
Objective. Define effective FTE and output-equivalent FTE, show how each is derived at app-logic level, and keep them distinct from headcount and from cash.
A dictionary entry. Effective FTE expresses productive capacity in full-time-equivalent terms; output-equivalent FTE expresses delivered work in the same unit so a team's output can be compared with the staffing it theoretically represents. Both are capacity statements, not cash and not headcount.

What it is
Effective FTE restates the productive capacity a team actually supplies as a number of full-time equivalents, rather than just counting bodies on payroll. Output-equivalent FTE restates the volume of work a team delivered as the number of full-time equivalents that volume represents at the agreed standard. Comparing the two answers a single question: is the staffing we pay for turning into the output it should? Both are expressed in FTE so a leader can reason in a familiar unit, but neither is a payroll headcount and neither is a cash figure.
How it is calculated
At app-logic level: effective FTE builds up from productive/available time (not raw paid hours) normalised against a full-time hours basis; output-equivalent FTE builds up from completed work valued at the standard handle time (see MET-08) and then normalised against the same full-time basis. Included: counted work and the time basis the account has defined. Excluded or adjusted: leave, non-counted work types, and - for the output-equivalent figure - uncompleted or unverified work. The exact normalisation (what counts as one FTE of hours, how part-time and shrinkage are handled, how standards feed in) is configurable - confirm with product for a specific instance. The gap between effective FTE and output-equivalent FTE is a capacity signal, not a cash number.
How to read it and the common misread
Read output-equivalent FTE against effective FTE: if output-equivalent sits well below effective FTE, the team has capacity that is not converting to delivered work at standard - a prompt to investigate complexity, quality, process friction or standards, not an instant verdict. There is no universal target; the meaningful target is the customer's own baseline and trend. The common misread is to treat an FTE gap as money saved or as a headcount cut: it is a capacity opportunity that only becomes cash after it is verified and acted on (MET-20, MET-21). A second misread is comparing effective FTE across teams without first aligning work type, complexity, tenure, period and quality.
Where it appears
Primarily in Work Output (people and teams, cost and planning views), and it connects to Capacity Planning where required and available capacity are reasoned in FTE. It also underpins the output-per-paid-hour and cost-per-clean-unit measures. Treat the demo figures as illustrations on seeded data, not as a customer's realised numbers.
Interpretation check
A gap between effective FTE and output-equivalent FTE is a capacity signal to investigate, not money saved and not a headcount reduction. Cash only follows after verified recovery.
In the field
In the KnackGlobal displacement story, output-per-FTE and the effective-versus-output-equivalent FTE comparison are the backbone of the value case - but only once the paid-hours denominator, work type and tenure are aligned across the teams being compared.
Practical task
In the Work Output demo, find a team where output-equivalent FTE trails effective FTE. Write two sentences: one stating the capacity gap as an investigation prompt (not a saving), and one naming the next check you would run and what you would confirm with product about the normalisation.
Self-check
What is the difference between effective FTE and output-equivalent FTE?
Effective FTE restates the productive capacity a team supplies in full-time-equivalent terms; output-equivalent FTE restates the work it actually delivered, valued at standard, in the same unit. Comparing them shows whether staffing is converting to output.
A team shows 20 effective FTE but 15 output-equivalent FTE. Is that 5 FTE of savings?
No. It is a 5-FTE capacity opportunity to investigate (complexity, quality, process, standards), not cash and not an automatic headcount cut. It becomes financial value only after verification and action.
Why can you not simply compare effective FTE between two teams?
Because the figure depends on work type, complexity, tenure, period and quality. Teams are only comparable once those are aligned, otherwise the gap reflects the mix, not performance.
What should you confirm with product before quoting an FTE figure for a customer?
The normalisation rules - the full-time hours basis, how shrinkage, part-time and leave are handled, and which standards feed the output-equivalent calculation - since these are configurable per instance.
Verified vs demo. The demo shows the FTE views on seeded data. A customer's effective and output-equivalent FTE depend on their own time basis, shrinkage handling and standards, which must be validated in their instance before any figure is quoted.
