Your supplier’s monthly report is full of green ticks. Response time met, resolution time within target, satisfaction comfortably above par. Yet a department head calls to complain that something has been going wrong for weeks. You search the report but cannot work out whether this is a one-off or a pattern. Sound familiar? Then you are probably measuring a lot and steering very little.<\/p>\n\n\n\n
The question of which KPIs matter for outsourced contracts has a simple answer: only the KPIs that change your behaviour. A figure that did not change anything you did last month is not a performance indicator, it is dead weight. The difference lies not in what you measure, but in whether the measurement leads to an action. That applies to cleaning just as much as to security, catering, technical maintenance, grounds care or IT services.<\/p>\n\n\n\n
A measurement score tells you what a measurement produced. Steering information tells you what you now need to do about it. That may sound like a detail, but it is the whole difference between a healthy contract and a dead one.<\/p>\n\n\n\n
Take an organisation with 40 sites and an outsourced maintenance contract. The report shows an average performance score of 8.1. Measurement score: fine. But three sites have scored below 6.5 for two measurements running, and one of them has an open complaint. That last point is steering information: it tells you where to hold a conversation and which action is outstanding. The average hides exactly what you need to know.<\/p>\n\n\n\n
The practical test for every KPI in your contract: did this indicator change anything you did last month? If not, you are measuring it out of habit, not to steer.<\/p>\n\n\n\n
During tenders, twenty to thirty indicators often creep into the specification. They sit there neatly, but in day-to-day delivery no one looks at them consistently. The more you measure, the less ownership each figure carries. Public procurement guidance is clear on this: KPIs should be as objectively measurable as possible and tied to underlying performance requirements. Not as many indicators as possible, but the ones that are defensible and steerable.<\/p>\n\n\n\n
A limited set with a clear owner per KPI beats thirty loose indicators with no one responsible. The question is not: can I measure this? The question is: who does something when this KPI deviates, and what exactly?<\/p>\n\n\n\n
The biggest stumbling block with KPIs is subjectivity. “It looks tidy” is an opinion, not a score. The moment a discussion with your supplier turns on interpretation, it becomes a matter of one word against another and you lose your grip on steering.<\/p>\n\n\n\n
Objective standards solve this. For many services, standardised measurement systems exist that produce a reproducible score based on sampling and set criteria. In cleaning, those are systems such as VSR-KMS and NEN 2075; in security and maintenance you work with performance-based acceptance criteria from the specification. The core is the same: two assessors measuring the same situation arrive at comparable outcomes. That makes the KPI defensible towards your supplier and towards your management. With a standardised measuring stick through quality management<\/a>, organisations on average halve the time per quality inspection, because the debate over interpretation disappears.<\/p>\n\n\n\n For most outsourced services a small set is enough. For each KPI, what counts is: what you measure, why it steers, and how you record it.<\/p>\n\n\n\n Alongside these hard figures, soft KPIs count too: reporting quality, timeliness of delivery, and cooperation in solving problems. They are harder to score, but a supplier that delivers reports late and incomplete is telling you something about how the contract is running.<\/p>\n\n\n\n The KPI “response time” often means something different to the supplier than to the client. Does the clock start at the report, at confirmation, or at scheduling? Without a shared definition, every evaluation costs time in debate and erodes trust.<\/p>\n\n\n\n Client, supplier and any adviser need to look at the same truth. That only works if, per KPI, you set out what is measured, by which method, over which period, and what the threshold value is. Contract performance evaluation models confirm that joint assessment works better than a score imposed by one party. A KPI that both parties understand the same way is half the work done.<\/p>\n\n\n\n A KPI that lives in a separate reporting system is a dead figure. Only when the score sits alongside the outstanding actions, the SLA agreements and the indexation in the same contract overview<\/a> does it become steering information. Then you can see straight away whether a low score has already led to an action and whether that action is on track.<\/p>\n\n\n\n In multi-year contracts, KPIs also age. A baseline measurement from year one says little in year four, and requirements around sustainability (CSRD, socially responsible procurement) are added contractually more and more often. So recalibrate your set periodically: drop the indicators that no longer steer anything and add what now counts. With 67 per cent of facility services outsourced in 2025, up from 54 per cent in 2021, that recalibration is becoming the rule rather than the exception.<\/p>\n\n\n\nThe four KPIs that actually steer outsourced services<\/h2>\n\n\n\n
