Strengthening team cohesion

Created 3 years ago, Sommet Education is the international specialist in hospitality management education. Sewster is working together with them to develop the company's corporate culture and strengthen links within the executive committee and local teams.

Key roles

• Organisation of a renewed executive committee
• A largely experience-based leadership programme
• Regular collaboration on strategic projects

01 The origins of the project

Stéphane Rousseau, Chief People Officer, Sommet Education

“Sommet Education was created with the backing of a real HR project. This challenged us to consider our values, our corporate culture and how to share these effectively with all employees and an almost totally new executive committee; which needed a real boost in cohesion. I was looking for support, with people who I felt compatible with.”

 “One of our specific needs was to work with a very high-level consultant who was not French to facilitate the work with the international members of the executive committee. Sewster introduced us to Matthew Anderson, who was the perfect match for this need. We are in the teaching business, and Matthew, with his PhD research subject, as well as his extreme rigour, was a natural match.”

02 Several projects at the same time

 “We had a lot of work in front of us, with an HR project based on the company’s values and culture, linked to the implementation of internal leadership cohesion. This cohesion was important both on an executive committee level and in the management “front line” in our institutions.”

 “There was a brief very intensive phase that went very well. I felt Sewster had a rare listening capacity, as well as the ability to challenge us in a way that was always relevant. We very quickly moved into an extremely fluid partnership, working together closely.”

03 An experience-based leadership program

 “From the beginning, Sewster insisted that we work with Pegasus at the Lorient base. I wasn’t very keen on this, as I don’t think that the purpose of this type of programme should be to test my employees. However, I accepted the experience because I trusted them.”

 “I went along with our management teams in Lorient for this “special forces” team-building experience. They still talk to me about abseiling down the bunker. It wasn’t just the tasks themselves that we appreciated, it was above all the care taken in planning and ensuring that everyone achieved an objective. I was right to place my trust in them despite my initial reluctance!”

04 The partnership continues...

 “I really feel like we are partners. There is real trust, our profiles are complementary, and the Sewster team is always extremely reactive. We know that we can rely on them to manage complex situations.”

Transforming talent into future leaders

Together with Geodis, Sewster has designed an in-depth program to develop the company's future talent. An ongoing partnership that continues with the implementation of similar initiatives within the different teams.

Key roles

• A tailor-made program for the development of employees with high potential
• A program that is now being replicated within the teams
• An advisory role that continues on a day-to-day basis

01 The origins of the project

Nathalie Jost, Global Organisational & Talent Development Manager, Geodis Freight Forwarding

“When I joined Geodis, we felt it was necessary to set up a real programme to develop the skills of the company’s employees who had great future potential. Coming from the consulting world myself, I had already had the opportunity to collaborate with Benoit and Emmanuel from Sewster and to value their approach as much as their methods. So I naturally asked them to consider this project.”

02 Co-creating a programme

 “We wanted a programme that would have a real impact on the development of our future leaders. This led us to reflect on what we term someone with high potential, and to establish the precise development focuses that we wanted to work on – self-awareness, self-confidence, entrepreneurship, openness to the outside world and the ability to make good decisions in complex situations. I wanted to receive ideas, experience and a network from Sewster in order to design a truly collaborative program.”

 “This whole phase was carried out quite quickly, thanks to efficient iterative work. I particularly liked that at every meeting, Sewster tries to go a little bit further. In the end, we really had the feeling that we had co-constructed a 100% tailor-made program.”

03 Implementation of the program

 “The program was rolled out over four full weeks of work over a 24-month period. I was really satisfied with the quality of the speakers, as well as the organisation of the sessions. The subjects discussed were always in line with our challenges. Participants remained attentive throughout, despite long sessions. And many of them came to me after to tell me that it was the best programme they had ever taken part in.”

04 The partnership continues...

 “We felt that Sewster’s interest wasn’t just for show, that there was a desire for this to be a longer-term relationship. The most striking example is that Benoit always participates in discussions in the programme participants’ Whatsapp group. Sewster is also very proactive, and spontaneously feeds us with new ideas, which are always relevant because of their knowledge of our company!”

 “For me, one of the greatest successes of this programme is to see that participants are constantly handing down what they have learned in their teams, sometimes by replicating what was learned with Sewster’s support, and so carrying on contributing today to developing talent at all levels of the company.”

A partnership that goes from strength to strength

Sewster has been working with Cartier Joaillerie International’s management for several years. It is a partnership that is constantly renewed according to the company's needs.

Key roles

• An advisory role in the Management Committee
• Tailor-made projects in line with challenges
• A relationship based on trust and high standards

01 The origins of the partnership

Tanguy de Bernède, Director of Cartier Joaillerie International

“I knew Benoît Auger, with whom I had had the opportunity to work with regularly, well. I value his analytical skills, his working methods but also his sensitivity. We understand each other perfectly. It was therefore a natural next step to work together with Sewster, with a desire to rediscover the same qualities, but on a team scale.”

02 Diverse assignments

“Rather than launching a major structural change project, our partnership flourishes through the diverse assignments. We trust them to help us solve a number of challenges. In general, Sewster plays an advisory role to the manager and supports us in building team spirit in our management, while weighing in on more specific assignments.”

“For example, we called on them when recruiting new members to our management team; something which was a major challenge for us. It had to be done swiftly and successfully! This resulted in real coaching sessions on how to recruit successfully, based on standards already tried and tested by Sewster, while at the same time being completely tailored towards our needs.”

“I also reached out to them on very different matters, such as mediation methods in our communication with other departments. To return to a more general aspect of our partnership, the models we develop together within the executive committee are regularly reproduced within the teams, after having been adapted to the context.”

03 A long-term relationship

 “I can see the positives of our continued work together. The defining feature in my eyes are high expectations from both parties. Our discussions are direct and completely honest. We are always questioning ourselves, trying to push ourselves out of any ruts fallen into to ensure that we find the best solution. These expectations are essential qualities for me. They go without saying in the luxury business sector.”

“We trust Sewster, we know each other well and we understand each other perfectly. And our relationship is backed-up by a well thought-out commercial framework. We discuss the nature of the support we need and a business proposal is drawn up to turn our roadmap into a reality, all for a justified price. We don’t talk much about this aspect, but it is important.”
