About IMA Worldwide

Implementation, Not Installation. That is AIM.

Q: What does IMA Worldwide do?

IMA Worldwide delivers four kinds of work. First, enterprise change management consulting that applies AIM from sponsorship design through reinforcement after go-live. Second, AIM practitioner certification for client teams. Third, AIM enterprise licensing for organizations building internal change capability at scale. Finally, AI-specific change management for AI rollouts using the AIM AI variant suite.

Q: What is the IHA assessment, and what is the IMA World Report?

The Implementation History Assessment (IHA) measures past change initiative outcomes to predict future implementation risk, hosted on the Comparative Agility platform. In addition, the IMA World Report is a forthcoming cross-client report drawn from the IHA cohort. Once published, it will allow organizations to compare their implementation track record against an anonymized aggregate of cross-client results.

Most transformations install the new system and stop. The Accelerating Implementation Methodology, developed by Don Harrison and delivered today by IMA Worldwide with Peacock Hill Consulting, is the framework for what comes after. Observable behavior change. Leadership accountability. Reinforcement that holds.

Positioning

A 37-Year Methodology Built for the Era After Go-Live

Most change management firms sell installation: communications plans, training calendars, and readiness surveys. IMA Worldwide, however, sells implementation. The work begins where most programs declare victory. Specifically, AIM treats the transition from installed change to sustained behavior as the measurable outcome, not project completion or training delivery.

The methodology codifies six leadership tasks sponsors cannot outsource to a PMO or consultant. In addition, it provides the EMR framework (Express, Model, Reinforce) and four scored diagnostic instruments that produce quantitative readiness baselines against a cross-client benchmark cohort. Thirty-seven years of field research since 1989. One specific job: closing the gap between go-live and sustained adoption.

The Methodology

AIM and the Four Scored Diagnostic Instruments

The Accelerating Implementation Methodology (AIM) ships with four scored diagnostic instruments hosted on the Comparative Agility platform. In addition, it includes five structured workbooks and audits, plus an extended commercial suite covering leadership 360s and the AIM AI variant suite. Fifteen named instruments in total. Specifically, the four scored core instruments are below.

IHA
Implementation History Assessment. Scores an organization's track record on past changes against a cross-client benchmark cohort.
IRA
Individual Readiness Assessment. Six-sub-index profile across Information, Willingness, Ability, Confidence, Control, and Feedback.
TRI
Targeted Reinforcement Index. Measures reinforcement architecture coverage and alignment across the change population.
IRF
Implementation Risk Forecast. Forward-looking risk snapshot across the methodology's critical success factors.

How is AI changing change management in 2026?

AI accelerates the pace of organizational change and exposes the leadership and reinforcement gap that traditional methodologies do not address. As a result, AIM is well positioned for AI transformation because it focuses on observable leader behavior and reinforcement systems, the parts of change AI alone cannot deliver. In addition, the AIM AI variant suite extends the methodology with five instruments built specifically for AI rollouts.
