Integrated Facility Management (IFM) wasn’t a management trend. It had solid economic logic behind it.
The foundation is Transaction Cost Economics, Ronald Coase’s idea, extended by Oliver Williamson. The core point is that organizations outsource when coordinating something externally is cheaper than doing it in-house. For Facilities Management (FM), the numbers historically favored outsourcing and consolidating to a single provider, making the maths even cleaner: fewer contracts, fewer interfaces, fewer pain points.
“The costs of using the price mechanism, the friction of every transaction between separate parties, are what determine where the boundaries of a firm should lie.”
Ronald Coase, The Nature of the Firm,1937
Prahalad and Hamel extend it from a different direction. Their 1990 argument was simple: focus on what you’re genuinely good at and outsource the rest. If your edge is in retail, healthcare, or hospitality, cleaning rosters and Mechanical & Electrical (M&E) schedules aren’t your problem to own.
“Few companies are likely to build world leadership in more than five or six fundamental competencies.”
C.K. Prahalad & Gary Hamel, The Core Competence of the Corporation, Harvard Business Review,1990
The market followed. IFM grew steadily across large multi-site estates; the benefits were real: standardized reporting, cleaner governance, aggregated buying power, one throat to choke. It brought genuine coherence for larger, dispersed portfolios.
That commercial logic hasn’t gone away. JLL’s 2025 Global State of FM Report found that 84% of FM leaders name rising operating costs as a top concern. In that environment, a single integrated provider still makes sense for the majority of CPO and CFO. For some, it’s not just convenient, it’s a financial necessity.
The model worked, and for many organizations, it continues to work well.
But the same theory tells you when it stops working
Transaction Cost Economics doesn’t unconditionally back outsourcing; Williamson was clear: the more specialized and critical an asset becomes, the riskier it is to hand it to a single external party. At high asset specificity, the logic shifts back toward keeping things in-house or managing a more deliberate mix of specialist providers.
“Asset specificity is the big locomotive to which transaction cost economics owes much of its motive power.”
Oliver Williamson, The Economic Institutions of Capitalism,1985
These questions are already appearing in the FM strategy discussion. The FM landscape is changing, and several forces are making the decision to move to a full IFM model less obvious.
Technical complexity has increased sharply
Smart buildings, cyber-physical security, decarbonization, compliance-heavy engineering, and social concern have changed what FM delivery actually requires. A supplier that delivers soft services well may not be the right answer for building energy management or AI-enabled security. As work becomes more specialized, the case for specialists grows stronger. The Royal Institution of Chartered Surveyors (RICS) and the International Facility Management Association (IFMA) have flagged that outsourcing models built primarily on cost reduction carry delivery risks in terms of expertise, motivation, equality, and operational resilience.
Transforming a fragmented model is rarely straightforward
Moving from a fragmented FM operating model to a fully integrated one is a major transformation program. Supplier rationalization, contract novation, TUPE (Transfer of Undertakings (Protection of Employment) Regulations) considerations, asset data cleansing, technology integration, governance redesign, and service standardization all require significant effort.
Delivering a successful IFM transformation often requires dedicated internal resources with expertise in procurement, contract management, operations, change management, and FM delivery. For organizations that lack these capabilities, the journey can become lengthy, resource-intensive, and more costly than initially anticipated.
The promised savings have not always materialized
The business case for IFM is often underpinned by reductions in management layers, economies of scale, and supply chain leverage. In practice, the transition costs are high, mobilization is complex, and margin stacking can eat the savings. Building a robust baseline can also be challenging, particularly when existing delivery models are fragmented and data quality is poor or inconsistent, making it difficult to accurately quantify the full benefits achieved.
Technology has removed one of IFM’s structural advantages
The old argument for a single supplier was partly about data. Systems (sometimes business units) didn’t talk to each other, so the IFM provider had to; that’s no longer always true. Computer-Aided Facilities Management (CAFM) platforms, open Application Programming Interfaces (APIs), Internet of Things (IoT), and real-time dashboards allow clients to integrate data across multiple providers without bundling the providers themselves. Integration is now a capability you can buy separately, not the main reason for consolidating services.
The insourcing moment
Recently, the government announced that around 2,000 facilities staff in cleaning, catering, and security would be brought back in-house. The Trades Union Congress called it a signal of intent. Whether it marks a genuine turning point or a political moment remains to be seen, but it’s the kind of move the FM sector tends to notice, and it will be mentioned at the next review or around the coffee machine.
Not the end of IFM, but perhaps the end of maximum consolidation
FM has always moved between consolidation and specialization, centralization and decentralization. The answer often depends on organizational maturity, estate size and complexity, internal capability, and the priorities of the CFO, CPO, and operational teams.
This isn’t an argument that IFM has failed; it is more that the conditions that made full consolidation optimal are changing, and the theoretical frameworks that justified IFM also tell you when to question it.
A more nuanced model is emerging (or re-emerging): a small number of specialist providers, each selected for category excellence, held together by a unified governance and data layer. The Service Integration and Management (SIAM) framework, originally from IT outsourcing, is probably the closest analogy, as it separates service delivery, performed by specialists, from service integration, owned by a neutral governance function.
The real question isn’t single supplier vs multiple suppliers. It’s who owns integration.
- It can sit with the supplier (the traditional IFM model)
- With the client (which needs a capable in-house function)
- Or with an independent integrator, a neutral third party focusing on governance, performance, and supplier coordination
And there’s a deeper question: as FM becomes more technically complex, more compliance-driven, and more tied to sustainability and smart building outcomes, does it still count as a non-core function that can be fully outsourced? Or does it start to move toward the boundary of the business, where Coase would say it belongs when specificity is high?
Perhaps the future of FM is not maximum integration, but smart integration.
Questions to take into your next FM review
- Has asset specificity in your estate increased since your IFM contract was signed?
- Are the savings promised at mobilization still materializing, or has a convenience premium quietly replaced them?
- Is your provider operating at the frontier of innovation, or maintaining a comfortable incumbent position?
- Could technology now deliver the integration benefits you are paying a management margin for?
- If you moved to a multi-provider model, who would contractually own integration?
- Is FM still genuinely non-core, or has it become strategically significant enough to reconsider?
