Most confusion in Facility Management comes not from missing knowledge but from collapsed concepts. These pages hold the distinctions the whole platform rests on: what gets conflated, why it happens, and how to tell the concepts apart in practice.
Three choices almost always presented as one.
Operating model decides who decides; sourcing model decides who delivers; contract model decides how it's settled.
Read onThree roles rarely held by the same person and rarely wanting the same thing.
The client pays, the customer asks, the user experiences — three interests that rarely align.
Read onA market split presenting itself as a taxonomy.
Hard, soft and enabling are procurement labels, not an analytical framework.
Read onThree models that appear to describe the same diagram.
Lifecycle describes when something happens, management system describes who controls it, value chain describes why it has effect.
Read onConsensus document or market product — the difference sets the weight.
A standard is consensus with status; a framework is a good idea without normative weight.
Read onDelivered result or achieved effect.
Output is what was delivered; outcome is the effect that matters.
Read onTwo Dutch concepts presented as consecutive rungs.
Regie keeps steering; demand keeps only asking.
Read onWhere is the boundary between operation and portfolio?
CRE decides what you have; FM runs what you have.
Read onSoftware or governance.
CAFM records; the management system decides.
Read onSustaining or trading off.
Asset management decides what to do with assets over time; maintenance management keeps them working now.
Read onTwo spellings, or two disciplines?
Same discipline, two regional spellings.
Read onWho protects the asset's value and who operates the space?
Property management protects the asset's value; FM operates the asset in use.
Read onA separate discipline, or a subset of FM?
Workplace management is inside FM's scope, not a synonym for it.
Read onTwo market labels, or two categories?
Two market labels for largely the same territory; don't treat the narrower reading as authoritative.
Read onA broader category, or an experience-focused subset?
Workplace services is soft FM's more experience-branded subset, not a separate category.
Read onA sourcing decision, or an operating model?
Outsourcing is what you delegate; regie is how you stay in control of what you delegated.
Read onTwo names, or two propositions?
Different vendors' preferred label for largely the same integrated-delivery proposition.
Read onThe supplier's offer, or the client's shape?
IFM describes the supplier's offer; demandorganisatie describes how much the client has hollowed out its own retained function.
Read onManaging the document, or managing the relationship?
Contract management runs the document; supplier management runs the relationship.
Read onThe agreed standard, or its measurement?
The SLA sets the bar; the KPI measures whether you clear it.
Read onThe proxy, or the actual effect?
KPIs are the proxy; outcomes are the point.
Read onWho pays, and who experiences?
The customer pays; the user experiences — and FM has to satisfy both.
Read onExecuting daily, or setting direction?
Strategic FM decides what 'good' means; operational FM delivers it daily.
Read onWhere does record-keeping stop and portfolio management begin?
IWMS is CAFM plus real estate, projects and sustainability, though the market rarely respects the line cleanly anymore.
Read onA structured model, or a living model?
BIM is the structured model; a digital twin is that model kept alive with real-time operational data.
Read onControlling the building, or managing information about it?
A BMS runs the building; an IWMS runs the information about the building.
Read onCalendar, threshold, or forecast?
Preventive runs on a calendar, condition-based runs on a threshold, predictive runs on a forecast.
Read onTwo chains hold the platform together: one from demand to delivery, one from term to evidence. Each step links on to the next.
The platform's vertical chain: why FM exists, what it delivers, how it is organised, how it is managed and what it rests on.
Demand precedes the catalogue.
What is actually delivered.
Who decides and who delivers.
How it is governed.
What the concepts are based on.
The horizontal chain: look up a term, read the distinction underneath it, find the knowledge behind it, check the standard and see how strong the evidence is.
Which meaning applies here.
What gets conflated.
Which discipline the knowledge comes from.
Whether it is standardised.
How strong the evidence is.
