Six waves, one global template, and a legacy system everyone has learned to bend.

Complexity

Impacted population

8,000–40,000

Primary change dimensions

Process standardizationData harmonizationRole redesignSystem replacement

Likely ADKAR risk

Ability — training completed but system confidence absent

Major stakeholder challenge

Power users defending decades of workarounds and local influence

Evidence

Tier B — documented S/4HANA cases incl. Colgate-Palmolive, Unilever, Mondelez; multiple Prosci award-winning SAP programmes

Everyone is an end user, and the managers are the ones being asked to absorb the work.

Likely ADKAR risk

Desire deficit among people managers absorbing HR BP tasks

Major stakeholder challenge

Every employee is an end user; managers gain work

Evidence

Tier B — Prosci-certified practitioner documentation across HRIS programmes

Roles, rights, reporting lines and governance change at once — no single intervention suffices.

Complexity

Impacted population

Likely ADKAR risk

Desire — role elimination fear dominates every population

Major stakeholder challenge

Leaders defending scope while their own roles are redesigned

Evidence

Tier B — distributed ADKAR barriers documented across TOM programmes

Two legacy populations, two ADKAR profiles, one Day 1.

Complexity

Likely ADKAR risk

Desire — asymmetric across acquirer and acquired populations

Major stakeholder challenge

Two sponsor coalitions, two cultures, one operating model

Evidence

Tier B — consulting-firm M&A OCM practice patterns; 50–70% of deals fail on people-side causes

Desire is the barrier. Training before Desire is money burned.

Likely ADKAR risk

Desire — existential role-security fear blocks all training value

Major stakeholder challenge

Employees who believe AI threatens their job will not engage

Evidence

Tier B — newest archetype in the Prosci case universe; Desire reported as dominant gap

Desire is not the barrier here. Ability is.

All five milestones under pressure simultaneously

Major stakeholder challenge

Regions losing headcount while retained roles absorb new discipline

Evidence

Deployment ≠ adoption. Nobody has signed the legacy shutdown.

Capacity is a change variable, and nobody has budgeted it.

Likely ADKAR risk

Ability at the sponsor layer — leaders know the message, cannot perform the role

Major stakeholder challenge

Sponsors who equate approval with sponsorship

Evidence

Tier B — sponsorship identified as #1 success determinant across 11 editions of Prosci research

The measurement system is part of the change — or its strongest opponent.
