Change Management Diagnostic Suite
The AIM Change Management Toolkit: Diagnose Where Your Change Is at Risk
The AIM (Accelerating Implementation Methodology) Change Management Toolkit is IMA Worldwide's suite of 15 scored diagnostic instruments for enterprise change. Not a software product: the field-tested diagnostic suite Don Harrison developed at IMA Worldwide in 1989, refined across 37+ years of enterprise transformation work.
The AIM Change Management Toolkit contains 10 core diagnostic assessments plus 5 AI-specific extensions, totaling 15 scored instruments. The four most-referenced are the IHA (Implementation History Assessment), IRA (Individual Readiness Assessment), TRI (Targeted Reinforcement Index), and IRF (Implementation Risk Forecast). Together they identify implementation risk, leadership gaps, and readiness barriers so you can focus resources where they matter most, not everywhere at once.
Instruments deliver via the Comparative Agility platform with quantitative risk scores at every stage of an implementation, or as downloadable templates for teams working within existing survey infrastructure.
Start With the Symptom
Select the Pattern You Are Seeing
Each symptom maps to a specific diagnostic tool. Find what you are observing, and you will know where to start.
Symptom
Leaders approved the change but nothing is moving
Leadership is not cascading. Commitment disappears between levels.
Symptom
People say they are on board but behaviors have not changed
Reinforcement gap. The organization is still rewarding the old way of working.
Symptom
We keep hitting the same walls on every initiative
Organizational baggage. Past failures are predicting current outcomes.
Symptom
Too much going on. People are overwhelmed
Change saturation. Capacity is maxed out across the organization.
Symptom
People are resisting but we cannot pinpoint why
Readiness gaps across information, willingness, ability, confidence, or control.
Symptom
The technology is live but adoption is low
Installation does not equal implementation. Go-live is not the same as go-adopt.
Symptom
Culture is eating our strategy
Cultural misalignment. Current norms and rewards contradict the desired change.
You do not have unlimited time or resources. The purpose of AIM is not to do AIM, but to have AIM guide you in what to do. Use diagnostics like the Implementation Risk Forecast to identify where your implementation is at risk, then focus scarce resources on those priority areas only.
AIM Principle
Getting Started
How to Use the AIM Toolkit
AIM assessments are not meant to be used all at once. Begin with diagnostics, then apply only the tools needed for your specific risk areas.
Choose Your Delivery Mode
Select the Comparative Agility platform for enterprise delivery with benchmarking, or download exportable templates to work within your existing systems.
Diagnose First
Start with the IHA or IRF to identify your highest-risk areas before selecting additional tools. Evidence replaces guesswork.
Focus Resources
Use targeted diagnostics only where real risk exists. The goal is precision, not completeness. Apply tools to the areas flagged by your initial assessment.
Act on the Results
Translate diagnostic findings into targeted interventions: closing readiness gaps, strengthening sponsorship, or adjusting reinforcement structures.
Iterate as Implementation Advances
Repeat assessments at key milestones to track progress and identify new risk areas as the initiative moves from installation toward full implementation.
The AIM Diagnostic Suite
10 Core AIM Diagnostics
Diagnostic tools in AIM are designed to surface the root cause of adoption failure, not just symptoms like low engagement scores. Each diagnostic is research-based, platform-agnostic, and available via Comparative Agility or as a downloadable template.
Business Case for Action (BCA)
Creates the foundation that gives everyone a clear understanding of what is changing, why it is changing, and the consequences of not changing.
Define the Change Excel / PDFImplementation History Assessment (IHA)
Predicts success from organizational patterns around previous changes. Run first to surface baggage that will undermine the current initiative.
Assess the Climate Comparative AgilityOrganizational Change Stress Test (OCST)
Measures current capacity for change across the organization. Informs go/no-go decisions when competing initiatives are already consuming bandwidth.

Use Cases
AIM Assessments by Role and Scenario
AIM diagnostics apply to any transformation where behavioral adoption determines success. Select the scenario that matches your initiative.
ERP Implementation Readiness
ERP rollouts fail when organizations measure go-live rather than go-adopt. Use the IRF to identify gaps across all 10 practice areas and the IRA to verify end-user readiness for new workflows before cutover.
AI Transformation Readiness
AI introduces unique resistance patterns including job-threat concerns and skill anxiety. Use the AI Transformation Suite to measure leadership sponsorship, workforce readiness, and risk specific to AI-enabled change.
Merger and Integration Readiness
Mergers multiply disruption across every target group simultaneously. Use the IHA to surface organizational baggage from both entities, and the OCST to measure whether capacity exists for integration work.
Culture Change Readiness
Culture shifts require commitment, not just compliance. Use the IHA and TRI together to diagnose whether current norms, rewards, and leadership behaviors are reinforcing or contradicting the desired culture.
Operating Model Change
Restructuring roles and reporting lines creates high disruption. Use the WLDT (Work Life Disruption Test) to quantify individual impact, and the EMR 360 to verify that sponsorship is cascading through every affected leadership level.
Agile Transformation Readiness
Agile adoption often stalls at middle management. Use the Leadership Assessment to identify sponsorship black holes and the IRA to measure whether teams have the information, willingness, and skills to shift working models.
Common Questions
AIM Change Management Toolkit: Answers to Key Questions
What assessments are included in the AIM toolkit?
The AIM toolkit includes 10 core diagnostic assessments covering the full implementation lifecycle, from organizational climate and leadership readiness to reinforcement and risk forecasting. It also includes five AI-specific assessments purpose-built for AI transformation initiatives. All tools are available via the Comparative Agility platform or as downloadable templates.
How does the Implementation History Assessment work?
The Implementation History Assessment (IHA) asks participants to evaluate how well the organization managed previous change initiatives across key practice areas. It surfaces patterns of past failure that predict current risk. Organizations with a history of poor change management carry baggage that undermines new initiatives unless that baggage is explicitly addressed before the current change proceeds.
What is the difference between AIM diagnostics and employee surveys?
AIM assessments are validated diagnostic tools that measure specific implementation risk factors, from sponsorship gaps to reinforcement misalignment. They are structured around the 10 AIM practice areas, while general employee surveys measure engagement or satisfaction. AIM diagnostics produce actionable risk scores tied to specific interventions, rather than sentiment data that requires separate interpretation to become useful during a change initiative.
How long does an AIM assessment take to complete?
Most individual AIM diagnostic assessments take between 10 and 20 minutes to complete per respondent. The Implementation Risk Forecast, which covers all 10 practice areas, typically takes 15 to 25 minutes. Multi-rater 360 assessments such as the Leadership Assessment and Change Agent Assessment require input from multiple respondents and are managed through the Comparative Agility platform.
Can AIM assessments be used for AI transformation initiatives?
Yes. AIM includes a dedicated AI Transformation Assessment Suite with five tools purpose-built for AI-specific challenges including job-threat concerns, skill development sequencing, and infrastructure readiness. These tools address resistance patterns unique to AI adoption that standard change diagnostics do not adequately capture, particularly around workforce anxiety and leadership sponsorship gaps for technology-driven change.
Who should take AIM assessments in an organization?
Assessment participation depends on the diagnostic. Climate assessments like the IHA and OCST (Organizational Change Stress Test) are administered to leaders and managers. Readiness assessments target the affected employee population. Leadership 360s involve direct reports, peers, and supervisors. The Change Agent Assessment focuses on the team responsible for managing the change. Starting with the IRF helps determine which populations to assess first.
How are AIM assessment results used to drive action?
Results from AIM assessments are mapped back to the 10 AIM practice areas, identifying which specific areas carry the highest implementation risk. Leaders then prioritize interventions in those risk areas rather than applying equal effort everywhere. This prevents the common failure pattern of doing everything superficially and ensures resources go where adoption is actually at risk.
