Testimonials of our clients

After trying to optimise our company’s structure ourselves several times, we made the decision, with my associates, to call a specialised company. Convidencia has quickly shown itself as the best company to assist us by understanding perfectly our motivations, our vision, our specificities and our punctual difficulties.

Thanks to Convidencia’s work, we learned how to know our own company better. We have redefined our organisation, adapted it to real life situations and given everyone the opportunity to achieve their goals. All this required time, but this work was vital to build strong foundations. We have also discovered and mastered new processes and techniques that have helped us to develop cooperation and agility but also to use the potential of our company. All these methods have really found a place in our work and have given us the opportunity to increase our work’s efficiency. From my point of view, the most striking qualities at Convidencia are their listening capacity, their professionalism and a made-to-measure approach.

Further to an ADP conference held by Lionel Barets I called on Convidencia to develop Participative Dynamics actions in my teams. Considering my organisational context, I chose a segmented approach with several ad hoc interventions that could gradually support the collaboration which I wanted to set up in my company.

In these different exercises, Convidencia’s preparation of the seminars was always high-quality. They proposed made to measure solutions that really matched with my needs and they all were built according to my organisation’s level of development.

Convidencia competes in the very specific market of Participative Dynamics but also brings a real capacity to be able to work in professional environment. Their knowledge of organisational models and how they work is a great asset. The analytical vision on the organisation and Lionel’s realistic approach helped me to gradually make the change that I wanted.

Directeur Human Resources & Facilities, Nagelmackers

Convidencia was recommended to me by a former customer. As a good doubting Thomas, I followed a training in Participative Dynamics with Lionel Barets who later became a trainer at ICHEC. Then, I call on Convidencia to be part of a project to reorganise ICHEC lifelong learning.

What particularly pleased me about this project was Lionel’s ability to understand the organisational logics and manage complex issues. Lionel is not only an expert in participative methods but also in analyses of corporate structures. He contributed to the content and asked us the right questions. This skill was very useful for the strategic exercises related to governance that I had to put in place.

Brigitte Hudlot

Director, ICHEC -Entreprises

The experiences I had with the consultants were not always positive because the quality of the services didn’t systematically match the promises that was given. But I must say that after working with them several times they did bring us a lot.

I think this is especially due to Lionel Barets. who has the capacity to analyse at a very high level and a very good ability to identify personalities within teams. He is able to put all this into music!

I contacted Convidencia, as Human Resources Manager at the STIB, because I wanted my team to be more performant in mature decision-making. I wanted to make our meetings more efficient and empower my staff. As a good consultant, Lionel Barets directly touched on a sore spot and advised me about the solution I was looking for.

Our first collaboration happened during a training course in Participative Dynamics. We had directly plunged him into a real meeting case from which we were expecting concrete results and shared decisions on a particularly sensitive subject. He got through brilliantly and we continued to collaborate on other ad-hoc initiatives such as the training of HR Business Partners and the Diversity Council.

Thanks to the following results and the enthusiasm generated, other departments started to do the same.

I warmly recommend Convidencia for its great expertise in developing organisations and for its services that meet the workers’ needs. They are more and more asking for meaning and participative techniques that can support these needs. I personally believe a lot in collaborative models.

Bauduin Auquier

Partner, AgileMaker

I started working with Convidencia when we were trying to define the strategy at the Christian Mutual Insurance Company. In order to implement the new strategy, we had to manage a partial intern reorganization and create a new direction assembling coworkers from several departments. It was a great challenge to involve people concerned by this change. We had to know how to do it concretely. The Participative Dynamics Model offers all the required tools to realise such process of integration. I was quickly convinced and I became a supporter of the method. I was looking for a partner who could convince me that we would set a successful project. Convidencia became this partner because she had experience enough to do so.

I find their work method impressive: simple and practical tools that work perfectly well. Another strong point, according me, is Convidencia’s mental flexibility : they measure the change’s temperature all along and give pieces of advice adapted to the situation.
