Organizational Change Management Services

Forrester mapped fourteen providers in this market in 2022. By late 2025 it was mapping twenty six, and in early 2026 it published its first scored evaluation of the category.

Nearly doubling the provider count in three years is unusual. Most markets in analyst coverage move the other way, with vendor lists contracting as capabilities commoditise and acquirers absorb the specialists.

This one grew, and the reason is visible in every other technology category being evaluated at the same time. Organisations keep buying capable technology and failing to get value from it, and the failure is almost never technical.

Change as a capability rather than a project

Forrester's definition is compact: a method companies use to evolve capabilities via people, process, and technology.

The more revealing framing is what it says these services actually produce. OCM articulates the organisational ability to consistently recognise need, generate purpose, diffuse knowledge, integrate requirements, and adopt new practices throughout change at scale, so that change becomes a muscle rather than a single-endeavour exercise.

That distinction is the category's whole argument.

The traditional model was project-attached. An organisation implements a new system, budgets a change workstream alongside it, runs communications and training, declares go-live, and the change team disbands. Change was something you did to people during an implementation.

The capability model treats continuous change as the permanent condition. If an organisation will be reorganising, adopting, and retiring technology indefinitely, then the ability to absorb change is infrastructure, and building it once is cheaper than rebuilding it per programme.

Forrester's Q4 2025 framing extends this to remodelling the organisation to embrace change, optimising outcomes in the face of complexity and interdependencies, and upholding the value proposition for all stakeholders.

That last clause is doing quiet work. Upholding the value proposition for all stakeholders acknowledges that change has losers, and that a programme which delivers its business case while damaging the people inside it has not actually succeeded.

Inside The Forrester Wave: Organizational Change Management Services, Q1 2026

Published in March 2026 and authored by Angelina Gennis with James McQuivey, Faith Born, and Sam Bartlett, the evaluation scored twelve providers against twenty criteria grouped into current offering and strategy, sorted into Leaders, Strong Performers, and Contenders.

Boston Consulting Group placed as one of three Leaders, taking the highest current offering score of any provider and tying for the highest strategy score, with maximum marks across eight criteria, more than any other vendor evaluated. Forrester's positioning is that change leaders facing ambitious goals, high risk, and scrutiny will find assurance in its methodical approach and people centricity.

EY also placed as a Leader. Forrester recorded its strategy under three headings covering people, speed, and scale, and credited investment in AI-enabled tools for diagnostics, sentiment analysis, and content generation, with agile pods combining change strategists, data scientists, and experience designers to orchestrate strategy, governance, and coaching. Reference customers cited strength in strategy, change communications, and training, including orchestrating a culture shift by activating change agents and executive sponsors.

The preceding Landscape, published on 29 September 2025, covered twenty six providers and noted that the market has become expert-led, research-backed, and adaptive to broader trends including AI adoption. North Highland was among the notable providers in that report, and Perficient appeared in the 2022 edition with a vertical focus in financial services, healthcare, and oil and gas.

The gap this category exists to close

Read across analyst evaluations of technology markets and the same finding recurs with unusual consistency.

Conversation intelligence customers universally adopted coaching and rated it the least valuable capability, because most organisations only used the tools to record and listen to calls, which created work rather than removing it.

Cloud cost management platforms produce accurate recommendations that the people with authority to act on them have no incentive to implement.

Journey mapping produced elaborate artefacts that went on walls and changed nothing, because the fixing sat in functions that were not in the room.

Intent data lands in the CRM and sales development returns to working its own list within two quarters.

Knowledge management systems fill with content nobody maintains because documentation is unrewarded work.

In every case the technology worked and the organisation did not change. That is not five separate problems. It is one problem appearing in five categories, and it is what organisational change management services are sold to address.

Which explains the growth. As the volume of simultaneous technology change rises, the adoption bottleneck becomes the binding constraint on value, and a market forms around it.

AI is the driver and the tool

The current wave of demand is obviously AI-related, and the mechanism is specific rather than general.

AI deployment differs from previous technology change in a way that makes adoption harder. A new ERP changes how a process runs. An AI system changes what a person's judgement is for, which is a different kind of ask. Someone told their expertise is now a review function rather than the work itself has been given a smaller job, however the announcement was phrased.

That is a change management problem of a different order from learning new software, and organisations that treat it as training have misread it.

The category is also using AI on itself, which is worth noting because it is unusually well suited. EY's cited investment covers diagnostics, sentiment analysis, and content generation.

Sentiment analysis is the interesting one. Change programmes have historically flown blind between surveys, with leadership discovering resistance at the point where it becomes visible, which is usually too late. Continuous signal from communications, collaboration platforms, and support channels gives a change team something closer to a live reading.

It also raises the same governance question that appears in every category touching employee behavioural data. Analysing sentiment across a workforce is monitoring, and in several European jurisdictions including the Netherlands it brings works councils into the conversation with formal consultation rights. A change programme that surveils employees to manage their resistance to being surveilled is a position nobody wants to defend.

The measurement problem

The persistent weakness in this category is proving it worked, and the difficulty is structural rather than methodological.

Change management's contribution is entangled with everything else. If a transformation succeeds, the technology, the strategy, the market conditions, and the change programme all contributed, and separating them is not possible in any rigorous sense. If it fails, the same applies in reverse.

Adoption metrics are the usual proxy: system usage, training completion, engagement scores. They measure compliance rather than value. A workforce using a system because it is mandatory looks identical in the data to one using it because it helps.

The honest position is that OCM is bought on judgement rather than on evidence, and its buyers are typically senior enough to make that call without needing a business case that survives scrutiny.

That produces a market where reputation, method, and the perceived quality of the people assigned matter more than measurable outcomes, which is a fair description of what Forrester's criteria appear to reward. BCG's citation about assurance for leaders facing high risk and scrutiny is a description of confidence rather than of capability.

The uncomfortable use

There is a version of change management that deserves naming, because anyone who has been on the receiving end of a programme recognises it.

Sometimes an organisation makes a decision, knows it will be unpopular, and engages change management to manufacture acceptance. The communications plan explains why this is exciting. The engagement sessions collect feedback that arrives after the decision is final. The change agents are selected for enthusiasm.

That is not what the discipline claims to be and it is a substantial share of what gets practised. The tell is timing: genuine change management shapes the design, and performative change management starts after the design is locked.

Forrester's inclusion of upholding the value proposition for all stakeholders, and its crediting of people centricity in BCG's approach, suggests the discipline's own standards point away from this. The providers with the strongest reputations are generally the ones willing to tell a client that the plan is the problem.

For a buyer that is a useful evaluation question. Ask a provider for an example where their advice changed the decision rather than the communications. The answer distinguishes advisors from implementers.

What this says about the wider picture

An organisational change management market that nearly doubled in three years, and earned its first scored evaluation during the period when every enterprise is deploying AI simultaneously, is a market telling you something about where value is actually lost.

The technology categories in analyst coverage are largely mature. The products work. Detection engines detect, platforms integrate, models are accurate enough. What consistently fails is the organisation's ability to alter what people do as a result.

That is an expensive realisation arriving late, and it is why a services category built entirely on the human half of technology change is growing while the software categories around it consolidate.

The practical implication for anyone buying technology is worth stating plainly. If the adoption problem is the binding constraint, then the allocation of budget between the platform and the change capability is a real decision rather than a formality, and most organisations currently resolve it heavily in favour of the platform.

The evidence across categories suggests that is the wrong ratio.

Forrester does not endorse any provider named here, and tier placement should not be read as a recommendation to buy.
