The AIM Change Curve: Opportunity and Loss
Two distinct emotional journeys through organizational change, and the diagnostic judgment that decides which one you are looking at.
The change curve is a model of the emotional journey people move through during organizational change. AIM (the Accelerating Implementation Methodology) works with two curves: change experienced as opportunity and change experienced as loss. Deciding which one you are looking at is an active diagnostic decision, and AIM treats it as the practitioner's first move.
Two curves, not one
The change curve is a model of the emotional journey people move through during organizational change.
In the Accelerating Implementation Methodology, developed by Don Harrison, that journey takes two distinct forms. A change experienced as an opportunity and a change experienced as a loss are not the same journey, and they do not respond to the same intervention.
Deciding which one you are looking at is a diagnostic judgment the practitioner makes, and it comes before any of the moves that follow. Get it wrong and everything after it is aimed at the wrong thing.
What happens when you misread the curve
The misread that costs the most is treating grief as resistance.
When someone is on the loss curve, a successful demonstration that the change works does not reassure them. It can make things worse, because it confirms exactly what they were afraid of. The practitioner then reads the deepening reaction as stubbornness and applies more evidence, more communication, more pressure. None of it lands, because none of it addresses what is actually happening.
The reverse error is equally costly. Treating ordinary capability doubt as grief produces sympathy where the person needed a concrete answer, and slows adoption that was ready to move.
Resistance is a function of disruption, not negativity
This is a core AIM principle, and it is worth stating plainly because it runs against the common assumption that resistance signals opposition.
Even changes people actively want produce resistance. Resistance scales with how much of a person's established pattern is being disrupted, not with how they feel about the change. An enthusiastic supporter facing large disruption will generate more resistance than an indifferent colleague facing little.
The question is never whether there will be resistance. It is how much, how it will be managed, and how it will be paid for.AIM principle
You cannot push people through the curve
The stages are not skippable, and certainty does not transfer between people.
Someone further along cannot substitute their own confidence for another person's doubt, because that doubt is grounded in the second person's frame of reference and resolves only through their own experience. Pressure does not accelerate movement. Building readiness does.
What readiness consists of, and how to diagnose which element is missing when someone is stuck, is taught in AIM Practitioner Certification.
Why AI adoption is running both curves at once
AI adoption is where the two-curve distinction earns its keep.
AI adoption offers real capability gain and simultaneously threatens craft that people spent careers building. The same practitioner can be on the opportunity curve about one part of their work and the loss curve about another, in the same conversation.
It also repeats. A conclusion reached carefully six months ago can be invalidated by a new capability release, returning someone to the beginning on the new thing while they remain settled on the old.
The mixed feelings are measurable. In a Pew Research Center survey of 5,273 U.S. workers conducted in October 2024, 52% said they felt worried about future AI use in the workplace, 36% felt hopeful, and 33% felt overwhelmed. Because respondents could select multiple feelings, the percentages overlap. This is not necessarily confusion; it shows that people can experience competing reactions to change at the same time. Viewed through a change-management lens, they may be progressing along different emotional and adoption curves simultaneously.
This is the difference between a change curve used as a wall poster and a change curve used as a working diagnostic.
Common questions about the AIM change curve
How is the AIM change curve different from the Kubler-Ross curve?
The grief sequence is recognizable in AIM's loss curve. AIM's contribution is pairing it with a separate opportunity curve and treating the choice between the two as an active diagnostic decision rather than an assumption.
Does everyone move through the change curve the same way?
No. Movement is uneven, people move backward, and one person can occupy different stages on different parts of the same change at the same time.
Can the change curve be applied without certification?
The concept can be understood from any overview. Applying it as a diagnostic, correctly identifying which curve someone is on and what is actually missing, is a practitioner skill and is what AIM certification develops.
Why is AI adoption running two change curves at once?
AI offers capability gain while threatening craft people spent careers building, so the same person can be on the opportunity curve about one part of their work and the loss curve about another.
Where can I see the change curve applied to AI adoption?
Ann Marvin, Chief of AI Tools at IMA Worldwide, has written a first-person account of going through both curves herself while integrating AI into AIM.
Which side of the curve are you on?
Two different needs get confused here, and they call for different things.
You are in the change, and people are looking at you. You did not choose it, you are somewhere on one of the curves yourself, and you are still expected to be a steadying presence for a team. This is the position many managers and HR business partners are in, and it is what the ChangePro Workshop is built for. It uses a real change currently underway as the case study, and it develops two things together: your own readiness, and your ability to recognize what is happening for the people around you. No prior change management experience required, and it sits outside the certification path deliberately.
Leaders are included in this, not exempt from it. A manager absorbing a restructure they had no say in is going through the change first, whatever their title says, and trying to steady others from a stage you have not worked through yourself rarely holds.
You own the initiative. Change agents, project leads, sponsors, and centers of excellence. The requirement here is diagnostic skill, sponsorship contracting, and reinforcement design, which is initiative-level work rather than conversation-level work. That is Introduction to AIM, the Sponsorship Workshop, and AIM Practitioner Certification. Compare the AIM training programs.
The simplest way to hold the distinction: ChangePro is person to person. The rest of the portfolio is initiative to organization. Most people running a transformation eventually need both.
