How to choose a change management partner
Most enterprise IT programme failures are now diagnosed as change failures rather than technology failures. The buying question is rarely "does this firm understand change" and almost always "can this firm deliver change at the scale, geography, and language coverage our programme needs, without diluting the methodology with junior staff". Methodology choice (Prosci / ADKAR, Kotter 8-step, ChangeFirst PCI, or in-house frameworks) matters less than the seniority and availability of named change leads in the SOW.
Three procurement archetypes recur. Methodology firms (Prosci, Kotter, ChangeFirst, BTS) lead on certification, in-house change capability build, and where the methodology itself is part of what is being purchased. Big Four firms (Deloitte, KPMG, PwC, EY) lead on change wrapped around finance, HR, and ERP programmes where audit defensibility and integration with broader transformation matter. Strategy firms (McKinsey, BCG, Korn Ferry) lead on culture and performance transformation that extends beyond technology change. Specialist mid-market firms (North Highland, ChangeFirst, regional boutiques) typically deliver superior change leader access at materially lower fees for focused programmes.

Frequently Asked Questions
How much does change management cost?
OCM as a workstream inside an ERP or cloud programme typically runs 10-20% of total programme fees for mid-complexity change and up to 30% for high-impact, high-resistance programmes (large M&A integration, contentious operating model changes). A standalone change capability uplift for a 5,000-25,000 employee organisation runs $300k-$1.5M depending on scope and certification volumes.
Prosci or Kotter or in-house?
Prosci / ADKAR has become the de facto standard for IT and ERP programme change, particularly in North America, and is supported by certification volume in nearly every large SI. Kotter remains the methodology of choice for executive-led, urgency-driven transformations. ChangeFirst's PCI methodology has strong adoption in UK and EMEA. The methodology matters less than disciplined application; mixing methodologies across a programme typically causes more friction than the choice itself.
Should we build internal change capability?
Yes, for any organisation running more than one major IT programme per year. Internal change capability (typically a small CoE with certified practitioners embedded in major programmes) reduces external fees by 30-50% over a three-year horizon and meaningfully improves adoption outcomes. The CoE should own methodology, training, and capability uplift; external partners deliver programme-level change effort.
How do we measure change success?
Adoption and proficiency metrics (active usage, transaction throughput, error rates, ticket volumes) within 30-90-180 days of go-live are the only meaningful measures. Sentiment surveys and training completion are leading indicators but do not validate outcome. Build adoption measurement into the programme SOW with named metrics and target thresholds before the change workstream begins.
What contract structure works for change partner work?
Time-and-materials with named-resource clauses for change leads and CoE coaches. Fixed-price for training development and delivery, communications campaigns, and assessment work. Outcome-based fees can work for adoption uplift but only when paired with strong baseline measurement. Always require knowledge transfer, change collateral handover (in editable formats), and runbook documentation.
