PMI Switzerland has published an article on the gap between rolling out a change and achieving real adoption, and on ACAEM©’s practical approach to closing it. Grégoire Willommet will present it at the PMI evening event on 5 November 2026 in Geneva.
GWRC Advisory supports leadership teams and project teams through their transformations: a new system, a reorganisation, an integration, the arrival of AI. Senior expertise, a proprietary method, measured results. Change management support in Lausanne and French-speaking Switzerland.
And it is almost never a question of budget, technology or business expertise. Research shows that failure comes from the human side first: fragile buy-in, invisible sponsors, managers without the right tools, adoption that is never measured.
Your ERP, your CRM, your reorganisation are ready. Your teams are not, yet. With the arrival of AI, new operating models and accelerated restructuring, the gap keeps widening: tools are evolving faster than behaviours, roles and skills.
Enabling change: this is why we exist.

In each of these situations, one more communication plan is not enough. You need a structured adoption strategy, sustained over time. That is where we come in.
ERP, CRM, document management, business platform
Deployment is progressing, buy-in is stalling. Teams work around the tool or stay silent in meetings.
Restructuring, new scopes
The new organisation charts are published. Real decisions still go through the old channels.
Integrating two entities
The legal integration is complete. Two cultures, two ways of working coexist without ever really meeting.
Jobs and roles redesigned
The tools are already here. Job descriptions have not kept up. Teams swing between fascination and concern.

Proprietary framework, born in the field
We work with the people who carry the transformation and are accountable for it within their organisation.
Executive management and Executive Committee members
You launched the transformation and you are accountable for it. You want to know where adoption really stands, not what the reporting says.
HR directors and transformation leads
Organisation charts are changing, jobs are being redesigned. You want to equip your managers and give structure to the support.
Programme directors and PMOs
The project is hitting its technical milestones, but buy-in is slipping. You need a change management component that lasts.
The quality of a transformation is measured by the attention paid to people. We work on four fronts, with the same methodological framework.
We steer the transformation
For the duration of the project, we steer adoption alongside you, from scoping to embedding.
We make your teams autonomous
We build your teams’ skills and establish a lasting practice.
We work on your leadership stance
We support the executives and key roles who tip adoption.
We stay by your side
The sponsor’s trusted advisor, month after month, to see what’s coming and adjust.
An example of an engagement carried out end to end, from the initial diagnostic to adoption measurement.
The initial diagnostic placed three of the five ACAEM© dimensions in the risk zone: low sponsor visibility, managers without the right tools, adoption not measured. Eight months of structured support were enough to reverse the trajectory, and the measurement plan is now built into the organisation’s quarterly steering.
