How Viessmann is turning two teams into a strong unit in a short period of time

What happens when two teams with different cultures, expectations, and ways of working are suddenly expected to come together—across national borders? This was precisely the challenge faced by Viessmann, a leading global provider of efficient climate control, heating, water, and air quality solutions. With the help of MONDAY.ROCKS’ AI-powered team development tool, the company was able to strengthen the new joint team in a targeted manner, achieving measurable results after just a few months.

The Challenge: Bringing Two Teams Together Across Multiple Locations

Viessmann faced the challenge of merging two teams from the Operations division, comprising a total of 16 employees. The goal was to develop a shared vision, standardize communication, avoid misunderstandings, and strengthen mutual trust. At the same time, the individual strengths of both teams were to be integrated into the new structure without risking friction or a loss of efficiency.

Another challenge arose: The teams were spread across two locations in different countries, which made it even more difficult to build personal relationships. In addition, there were differing expectations and work styles, for example regarding meeting culture.

The moment a team is formed

"The contrast between the first and second meetings said it all. The first was marked by silence—the second by open, constructive collaboration. And that continued in all subsequent meetings."

The Solution: Targeted Team Development Based on Data Rather Than Gut Feelings

While searching for a suitable tool, Viessmann came across MONDAY.ROCKS through a recommendation and decided to use the AI assistant for team development. The tool enables teams to conduct regular, brief, and anonymous pulse surveys, the results of which are analyzed using AI and immediately provide concrete recommendations for action. It is based on 16 scientifically validated effectiveness factors—including trust, role clarity, communication, and conflict resolution skills—that provide an objective, data-driven foundation for team development. This is precisely what made it the ideal tool for a merger, where dynamics are difficult to pin down but crucial.

We start with an initial assessment in both teams—to clearly establish where everyone stands before the merger. Building on that, we conduct regular pulse surveys within the new, combined team structure. This allows us to continuously monitor developments and steer them in a targeted manner.

Measurable change in a short period of time

Shortly after the AI assistant was introduced, the teams began to show measurable improvements in several key areas:

Trust (+5%) & Conflict Level (-5%)

Trust within the team was deliberately strengthened, and friction among employees was noticeably reduced—a crucial foundation for the successful merger of two established teams.

Clarity of Roles & Speed of Implementation (+5%)

Responsibilities within the new team structure became clearer, decisions were made more quickly, and actions were implemented more consistently.

Openness to change (+4%)

New ways of working and shared processes were embraced more consciously—a strong sign of a growing, shared team culture.

The participants’ conclusion sums it up: “A better work environment, better communication, and better collaboration.”
