Introduction: why this action matters for adoption
Adoption fails when people are asked to support a change before the organization has clarified what the change is, why it matters, who is affected, and what success will look like. ACMP’s change management standard treats defining the change, determining why it is required, identifying goals and success criteria, and assessing readiness as early change management work, with inputs such as the business case, project charter, strategic plan, research, success measures, and expected benefits [ACMP, 2025]. (acmpmexico.org)
This action is a governance, planning, and operating model intervention. It creates a practical agreement about the minimum inputs needed before the change team builds adoption plans, asks managers to lead conversations, or measures readiness. Done well, it prevents “activity-first” change management: communications without a case for change, training without defined behavior outcomes, or engagement without decision rights.
What this action is and when to use it
This action establishes a documented input set for the change management process. The input set may include the case for change, definition of success, future-state vision, impacted stakeholder groups, expected behavior changes, benefits, risks, constraints, sponsor expectations, and measures of adoption. Prosci similarly frames early preparation around defining success, defining impact, and defining the approach before moving into detailed change plans [Prosci, 2025]. (prosci.com)
Use it at the start of a change initiative, when a project is moving from concept to delivery, when a sponsor asks for a change plan, or when impacted groups are confused about the purpose or success criteria. Revisit it at major phase gates, after scope changes, during resistance spikes, and before go-live.
Preparation: inputs, stakeholders, materials, timing, and decisions needed
Before facilitating the session, gather existing strategy documents, the business case, project charter, operating model design, process maps, technology scope, benefits assumptions, risk register, stakeholder analysis, and any prior employee feedback. ACMP identifies the business case, research, strategic plan, project charter, success criteria, and future-state benefits as inputs to early change definition work [ACMP, 2025]. (acmpmexico.org)
Invite the sponsor, project lead, change lead, business owner, representative people managers, HR or L&D partner, communications partner, data or benefits owner, and a small number of impacted employee representatives. Where resistance is likely, include credible informal influencers early; Gallup notes that effective change strategies involve both formal and informal power holders at appropriate points in the process [Gallup, 2020]. (gallup.com)
The key decision needed is not “approve the whole change plan.” It is narrower: agree what information is sufficient to start adoption planning, what remains unknown, who owns each gap, and when unresolved inputs become escalation items.
Step-by-step facilitation guide
Open with the decision to be made. Say: “Today we are not designing every change activity. We are agreeing the minimum inputs required to plan adoption responsibly.”
Confirm the change definition. Ask what is changing, for whom, by when, and what is out of scope. PMI emphasizes that change involves moving from current state to future state and that unclear future-state characteristics increase the risk of ending somewhere unintended [PMI, 2013]. (pmi.org)
Build or test the case for change. Facilitate a short discussion on opportunity, risk, consequences of not changing, expected benefits, and why now. ACMP states that the case for change should support the vision, articulate benefits, describe consequences of not changing, and address the risk of weak stakeholder adoption when the rationale is misunderstood [ACMP, 2025]. (acmpmexico.org)
Define success in business and adoption terms. Separate delivery success from adoption success. Delivery success might be “system live by October.” Adoption success might be “80% of frontline managers use the new workflow correctly within six weeks.” PMI advises measuring adoption, outcomes, and business results rather than only whether the change launched [PMI, 2013]. (pmi.org)
Map impacts by stakeholder group. For each group, document what changes in skills, processes, performance expectations, roles, technology, decision rights, and workload. AWS defines change impact assessment as looking at effects across skills, processes, performance management, and technology for each stakeholder group [AWS Prescriptive Guidance]. (docs.aws.amazon.com)
Assign owners for missing inputs. Do not allow gaps to become vague “project team actions.” Assign each gap to a named owner, with a due date and decision forum.
Agree the input baseline and review cadence. Close by confirming what is approved, what is provisional, and when the inputs will be refreshed. This keeps the structure actively used rather than filed away.
Example: how this could be applied in a real change initiative
A company is replacing a manual sales approval process with a workflow tool. The project team requests a communications plan. The change manager instead facilitates a 90-minute input-identification session.
The sponsor clarifies that the case for change is not “new software,” but reducing approval delays and improving revenue forecasting. Sales managers define success as faster approval cycle time, correct use of approval thresholds, and fewer escalations. Impact mapping reveals that finance analysts must stop accepting email approvals, sales managers must coach reps on new approval rules, and regional leaders need dashboard visibility. The change plan then includes manager coaching, role-based workflow practice, dashboard adoption measures, and a benefits review cadence rather than only launch communications.
Roles and responsibilities
Role | Responsibility |
Sponsor | Owns the case for change, resolves strategic ambiguity, and approves success measures. |
Change manager | Facilitates input identification, documents assumptions, identifies adoption risks, and integrates inputs into the change strategy. |
Project lead | Confirms scope, timeline, dependencies, constraints, and delivery decisions. |
Business owner | Owns operational outcomes and sustainment after implementation. |
People managers | Translate the case for change into team-level implications, surface resistance, and provide feedback loops. CIPD identifies people managers as communicators, coaches, implementers of strategy, and change agents who need information, capability, and support [CIPD, 2023]. (cipd.org) |
Impacted employees | Validate real work impacts and identify practical barriers to adoption. |
Benefits or data owner | Defines metrics, baselines, reporting cadence, and benefit ownership. PMI’s benefits framework emphasizes metrics, KPIs, benefit owners, and transition to operational owners [PMI, 2016]. (pmi.org) |
Common mistakes to avoid
The first mistake is accepting a weak case for change because the project is already funded. Funding explains priority; it does not automatically create employee understanding or commitment. The second is defining success only as delivery completion. PMI is explicit that value depends on adoption, use, and realized benefits, not output alone [PMI, 2013]. (pmi.org)
A third mistake is treating impacted groups as audiences rather than sources of input. Impacted employees often know the process exceptions, workload conflicts, and informal workarounds that determine whether adoption will happen. A fourth is letting success measures stay abstract. “Improve efficiency” should become a measurable outcome, a behavior change, and a named owner.
Measures of success or adoption indicators
Use a small set of indicators to tell whether this action is working: the change team has an approved input baseline; the case for change can be explained consistently by sponsors and managers; stakeholder impacts are documented at the level of role or team; success measures include adoption, behavior, performance, and benefits; missing inputs have named owners; and change plans are updated when inputs change. Prosci’s process emphasizes tracking performance and adapting actions during change, while PMI’s benefits framework emphasizes monitoring progress against benefit plans and sustaining benefits after transition [Prosci, 2025; PMI, 2016].
