The reports are green and the project is red: how to set SLAs, metrics and the definition of done
Campbell's law says that every metric which becomes a target gets distorted.
You measure response time, you get “accepted for processing” in seven minutes and a solution after
six days. The study separates three ideas that most companies confuse.

Cost of employment
What a full-time position really costs and how to work out the effective hourly cost
The effective hourly cost is the total annual cost of the position divided
by the number of hours in which the person actually does the work you hired them for.
It is always higher than the rate set in the contract, because it divides a larger amount by a
smaller number of hours.
In short
A full-time position costs the company roughly 1.2 × the gross salary once employer contributions to ZUS, the Polish social insurance institution, are added.
On top of that comes the cost of the position: equipment, licences, training, floor space, supervision.
Out of 2,080 calendar hours a year, what remains is about 1,500 available hours
after annual leave, sickness and public holidays.
Of that, the task you actually hired for usually takes 60–75% of the time.
At PLN 8,000 gross, the effective hourly cost lands around PLN 135–150,
and not the PLN 48 that simple division gives.
Seven steps
Gross salary × 12. The starting point, the same one that appears in the contract.
Add the employer contributions. Pension, disability, accident insurance, the Labour Fund and FGŚP, the guaranteed employee benefits fund,
add on the order of 20% to the gross salary. The exact mark-up depends on the accident insurance rate in your industry.
Add the cost of the position. A computer and a phone spread over three years, licences,
access to systems, initial and periodic training, medical checks, office space.
Add the cost of supervision. The manager's hours on conversations, approvals, appraisals
and problem-solving — counted at their rate, not the employee's.
Count the available hours. 2,080 calendar hours minus annual leave, public holidays and
statistical sickness absence. About 1,500 remain.
Count the productive hours. From the available hours you subtract meetings,
administration, switching between tasks and idle time. In office work what usually
remains is 60–75%.
Divide. The total annual cost by the productive hours. That is the number
you compare with an outside quote — never the gross salary.

Substitute your own numbers. The contribution mark-up depends on the accident insurance rate,
and the productive share on how many meetings and how much administration your company has.
The three commonest errors
Dividing gross pay by 160 hours. It leaves out contributions, the cost of the position and the fact
that a month does not hold 160 hours of work on one task.
Omitting the supervision cost. An hour of a decision-maker costs a multiple of the employee's rate,
and a new position takes the most of it.
Assuming full workload. A position costs the same in a month in which
there is half a position's worth of work.
What the time costs before a new hire starts producing results
Turnover cost is the sum of three things: the cost of the vacant position,
the cost of recruitment and the cost of bringing a new person to full productivity. The last
item is usually the largest and usually nobody counts it.
In short
One departure sets off three costs, not one.
Recruiting a specialist most often takes 6–12 weeks from the decision to the first day.
A new person reaches full productivity after 3–6 months, and not at the end of the probation period.
Onboarding also eats the team's time — usually several dozen hours of people who
already work for results.
An external team moves this cost to the supplier: recruiting and onboarding the next person sit on their side.
Component 1: the vacant position
The work does not leave with the person. Either it stops happening — and then the cost shows in the result —
or others take it over, and the cost shows in their overtime and in the tasks they set aside.
Count it as the number of weeks vacant × the weekly value of the work of that position.
Component 2: recruitment
Job adverts, the recruiter's time, the manager's hours on interviews, tests, medical checks, preparing
the workstation and the equipment. On a specialist position this easily reaches an amount matching
one or two months of salary.
Component 3: the productivity ramp-up curve
From day one a new person costs the full rate and delivers a fraction of the result. The typical course
in office work looks like this:
Month 1
approx. 25% productivity
Month 2
approx. 50%
Month 3
approx. 75%
Month 4 onwards
100%
Productivity lost over the first quarter
≈ 1.5 months of work
On top of that comes the team's time: questions, checking, corrections, explaining context.
With well-run onboarding that is several dozen hours of people who already work for results.
How to measure it in-house
Take the effective hourly cost of the position (see the study on the cost of a position).
Count the weeks vacant and multiply by the weekly value of the work.
Add up the real recruitment costs, including the hours of your own people.
Add 1.5 months of the full cost as productivity lost in the first quarter.
Add the team's hours spent on onboarding, counted at their rates.
In the external team model this bill arises on the supplier's side: recruitment
and onboarding are theirs. See what you can hand over →
Decision
Outsourcing or a position: which process to hand outside
Price rarely decides whether a process goes outside. What decides is whether the process can be described, handed over, signed off. Below are six entry criteria
and a list of situations in which a position works better.
In short
A process suits being moved out when it has an input, an output and a sign-off criterion.
The more repeatable and measurable, the smaller the risk.
Processes that require constant presence and owner-level decisions stay in the company.
Variable workload argues for hourly settlement, steady workload for a subscription.
Six questions before the decision
You know where the work starts. A list, a request, a document or a database — something that arrives at the input.
You know what gets produced. A concrete result and the form in which you sign it off.
A sign-off criterion exists. Someone can say “this is done well”
in a way that can be checked without discussion.
The work can be done remotely. Physical presence is the only hard boundary.
Company knowledge transfers in reasonable time. Once onboarding runs longer
than the project itself, the point disappears.
A rhythm exists. You know whether the topic comes back every month or happens once.
When a position works better
The work requires decisions that belong to the owner or the board.
The position is fully and predictably loaded all year round.
The process builds an advantage you want to keep inside the company.
Physical presence in a specific place is required.
Four qualification errors
Moving chaos outside. A process without a description becomes more expensive outside, not cheaper.
Comparing rates instead of costs. The supplier's rate covers supervision and onboarding the next person,
the gross salary covers nothing.
Splitting one process across three suppliers. The cost moves into
coordination on your side.
No one to sign off. Without a named person on the client side, every
project ends in a discussion about scope.
What to settle before the start so you do not pay for rework
The most expensive part of an assignment is misunderstanding, not execution. Rework
costs twice: once the supplier's work, once your people's time to explain the same thing
over again. A brief is cheaper than both.
In short
Seven brief fields close most rounds of rework.
The sign-off criterion goes down on paper before the first hour of work, not after it.
One person signing off on the client side — a single name, not a committee.
An example of “this is how it should look” works better than a paragraph of description.
Seven fields that close the matter
Business goal. What is to change in the company after delivery — not what is to be produced.
Audience. Who will read it, watch it, or take the call.
Scope. Itemised activities. This is the basis of the later settlement.
Input materials. What you supply and when — without it the deadline does not start running.
Sign-off criterion. The sentence that shows the work is finished.
Deadline and reporting rhythm. When delivery falls due and when status comes along the way.
Decision-maker. One full name on your side.
Checklist before the start
Can anyone describe the result in one sentence, without “and that sort of thing”?
Is there an example that may be shown as a model?
Is it clear what the supplier is not doing? (the one place worth writing out)
Are the accesses and materials ready on the start date?
Does the person signing off have time reserved for sign-off?
Why this is worth calculating
One round of rework on a 20-hour assignment is usually 4–6 hours of the supplier's work
and 1–2 hours of your team on explanations. With the effective hourly cost of a decision-maker
around PLN 150, two such rounds cost more than an hour spent on a proper brief.
A finished brief also comes out on its own, at the end of the assessment.

Supplier control
The reports are green and the project is red: SLAs, metrics and the definition of done
Campbell's law says that every indicator which becomes a target gets
distorted. You measure response time — you get “accepted for processing” in seven minutes
and a solution after six days. Three ideas that most companies confuse have to be separated.
In short
SLA is a contractual commitment about time — and about time only.
Metrics describe the quality and effectiveness of the work.
The definition of done says when a thing is finished.
Without a definition of done, a green SLA and green metrics can sit beside a project
that does not work.
Two indicators worth watching: First Time Right and Rework Rate.
Three different things
SLA
Response time and resolution time. A contractual commitment with a consequence.
Metrics
Effectiveness, quality, volume. They show how the work is going.
The definition of done
A list of conditions whose fulfilment closes
a task. Without it, “done” means something different to each side.
Two indicators that show the truth
First Time Right — the share of tasks accepted without corrections on first delivery.
It measures understanding, not diligence.
Rework Rate — the share of work carried out a second time. A rising Rework Rate alongside
a green SLA means the supplier keeps up with the reply and not with the solution.
How to set it in the contract
Write down the definition of done for each type of task before the first hour of work starts.
Set the SLA separately for response and separately for resolution — otherwise you measure only picking up
the phone.
Pick two to four metrics. More means nobody reads them.
Set the review rhythm: who talks, when, and on which numbers.
Write down what happens when a metric is red for two periods in a row.
Warning signals
A report that looks good while the organisation stands still.
Indicators calculated by the supplier and verified by nobody.
“In progress” statuses that persist longer than the reporting cycle.
The absence of one person who answers for the deadline by name.
Describe the area you want to hand over. The configurator will show the team, the way it is led
and the amount, and you can send the finished request or keep it for yourself.
