You sent the same deck to everyone.
One person started moving that afternoon. One had been ready for a year and just needed someone to say go. One asked a reasonable question you could not answer. One has not mentioned it since.
The deck was fine. The room was not one room.
The pattern underneath every barrier list
I ran a session on influence for a group of sustainability professionals. Before I was ten minutes in, they had filled a board with the barriers they were up against. Initiatives designed in silos and handed to the people who have to implement them. Sustainability buried under data and reporting with nothing left over for change leadership. Colleagues entrenched in what they already know, because that is exactly what they are rewarded for.
The list was long. Underneath all of it sat one pattern. We use the same approach on everyone, when the people we are trying to move are standing in different places.
You cannot talk someone into a different position. You can meet them where they are and make the next step look obvious.
Where the four stages come from
The stages of change model came out of health behavior research, where Prochaska and DiClemente described how people move through recognizable stages of readiness before a hard behavior sticks. It has been tested for decades in settings where the costs are real and the timelines are long. It is not a management framework invented for slide decks, and it is not mine. It just transfers, and it has not landed properly in sustainability practice yet.
The idea is simple. People are not uniformly resistant or uniformly ready. Each stage needs a different kind of support, and, more usefully, a different messenger.
Stage one: they are not listening yet
Their attention is filtering your message out. Sustainability is not in their frame of priorities, so it does not register. Hand someone at this stage a document full of sustainability content and they will tell you later, honestly, that they never saw it.
What does not work: a business case, a target, a deadline. Pushing harder produces a defended position, and now you have a public opponent who has to stay consistent.
What works: start from what they are already trying to deliver. Where does your change create a co-benefit for something they are measured on? Often the word sustainability does not need to be in the room at all.
The right messenger: a convert. Someone who looks very much like them, was skeptical, and convinced themselves. They speak the language. You usually cannot.
Stage two: they are weighing it up
They agree there is a problem. They have not decided it is worth what it will cost them. They say the right things, they may have signed the pledge, and they are stuck on the scale because the status quo still feels safer.
What does not work: more proof that the problem is real. They already agreed. Repeating the case reads as not listening.
What works: two levers. The first is emotional weight on the cost of not acting, something specific and present that they are already worried about. In that session, one participant described a leader who mentioned in passing that he was uneasy about clients judging them for still serving plastic water bottles. That is the lever. You find it and you press on it gently. The second is seeing a peer they respect already getting the benefit. The scale tips when being left behind starts to feel riskier than moving.
The right messenger: a competitive peer who has already made the call. A case study will not do it. A person will.
Stage three: they are ready but lost
They want to act. They are standing at the edge of the pool and cannot find the steps. From a distance their inaction looks identical to stage one, and that is the most expensive misdiagnosis in this work, because what you would say to a skeptic is exactly wrong for someone who is already convinced.
What does not work: more motivation. You will spend a meeting selling something they bought weeks ago.
What works: clarity. The first step, named, small enough to do this week, with a date and a person attached. We have been on this journey for years and we forget what it was like to not know the first step.
The right messenger: someone one step ahead who can reach back and take their hand. A supplier who just went through it. A category manager at a peer company who made it work. Close enough that the distance does not feel impossible.
Stage four: they are moving and struggling
This group gets overlooked because they seem fine. They are on board. They are also hitting the barriers hardest, absorbing every gap in the process, fielding the eye rolls when they walk into a room. They started on confidence and they are now running on willpower.
What does not work: assuming they are done and turning your attention elsewhere.
What works: problem solving support and recognition that progress is happening before the dashboard can show it. We tend to reward pledges and targets, which means we reward people for contemplating. The pledge gets the PR. The person actually in the room trying to move something gets nothing.
The right messenger: a group of peers in the same position, where a win for one is a win for all. Plus you, once. Recognition from a leader is one of the few things that only works coming from above.
The question most of us skip
Across all four stages, one question keeps surfacing. Am I the right person to have this conversation?
Often the answer is no, and that is a design opportunity rather than a problem.
A risk leader who already holds authority in risk conversations, carrying the human reality of climate risk, is a more credible voice than a sustainability director making the same argument. A category manager who has brought one supplier through this becomes the best coach for the colleagues who have not started. An engineer talking to engineers about packaging design does not need your vocabulary at all.
The shift is from asking what message to deliver to asking who already has the trust and the language to deliver it. That question takes longer to answer. It also works.
Before your next all-hands
Take the people who actually have to do something differently and sort them into the four stages. Then count.
If most of them are weighing it up, you have a cost problem rather than an awareness problem, and another round of communication will not touch it. If most of them are ready but lost, stop selling and start scheduling. If a handful are already moving and you have no plan to support them, you are about to lose them, and everyone watching will learn what going first costs.
One message to a mixed room reaches the part of the room that was already standing where the message was aimed.
Think about the stakeholder you have been stuck on longest. Which stage are they actually in? And who do they need to hear this from, if it is not you?
