Mission statement for post-merger integration of 9 departments
How a SME successfully integrated nine departments into one business unit through a mission statement.


The social dynamics of mergers and acquisitions always make managing the human side of M&As a major challenge.
We specialize in cultural post-merger integration. Our experienced viadoo Change Guides conduct cultural due diligence and ensure professional communication from Day-One. Mutual trust, shared identity, and collaborative value creation at the working level are our goals.

The list of goals for mergers and acquisitions (M&As) is long. Unfortunately, the list of failed M&As is just as long. Eighty percent fail due to a lack of post-merger integration, and 50% due to incompatible cultures (source: Roland Berger).
In plain language: if the workforce resists a merger or acquisition, consciously separates itself from each other, and does not want to identify with the new entity, the expected synergies will not materialize. The project fails, and restructuring / turnaround is often necessary. That is why human dynamics must be considered in M&As from the very beginning. This is particularly important in the due diligence phase (see below), at the latest from Day-One, when it is essential to quickly provide clarity for all those affected.
This requires specialists in communication, social psychology, and other disciplines. It requires professional handling of relevant factors such as culture, social identity, shared values, beliefs, and behavioral norms, Anti-Change-DNA, and emotions. This is precisely why organizations entrust viadoo Change Guides with the strategic planning and successful management of their Post Merger Integration (PMI).

We understand the expected synergies of the deal. We then analyze the culture of buyer and target, their stakeholders, and their likely emotions and reactions to the deal. We also develop a valid answer to the question of why the M&A is now inevitable. Together with top management, we then generate a vision of the new organization’s future as a guide for buyer’s and target’s employees.
We identify qualified change agents and train potential change agents. At the same time, we analyze the infrastructure for post merger integration communication. Finally, we set up the Integration Management Office (members, roles, governance, etc.). This allows us to identify areas of conflict at an early stage and facilitate solutions.
.
Based on the previous results, we formulate the change story and develop the change management architecture. This includes plans for stakeholder participation, sponsor involvement, necessary training measures, and target group-specific, agile change communication (topic and action plan). In this way, we strengthen trust in the M&A and in the executives.
We implement our change architecture in line with the integration plan (technical level). This includes among other things conflict mediation, overcoming dysfunctional teams, and soliciting feedback. In accordance with the agile communication strategy, we also provide ongoing information about even small steps forward. In the end, we actively contribute to your M&A success!
As with any change project, there is no one-size-fits-all approach to successful post-merger integration (PMI). However, every PMI project has typical milestones. As a neutral third party and the human side of M&As, we offer the following services as part of a typical PMI initiative.
• Evaluating the compatibility and potential clashes between the cultures of buyer and target to ensure a successful PMI.
• As a neutral third party, focus on tensions, fears, and faction formation in top management, middle management, and among the remaining employees of both organizations.
• Reviewing the due diligence report(s) to identify the issues to be addressed during the integration process.
• Establishing a strong Integration Management Office (IMO) team with an integration committee and transversal integration teams (e.g. IT system integration, HR topics).
• Developing a PMI Architecture and a PMI Communication Strategy.
• Implementing the PMI Communication Strategy regarding personnel decisions, planned structures, reporting channels, etc., with a focus on the information needs of middle management.
• Appointing new CEOs, managing directors, board members, and executives and promoting their integration (e.g., through conflict management workshops and team-building measures).
• Launching takeover period with decided joint operating structure.
• Implementing the PMI Architecture that puts people and culture at the heart.
• Accepting that this is a time of anxiety and uncertainty for employees of both merger partners.
• After 12 – 18 months cost-saving synergies begin to capture
• After +36 months culture changed successfully, buyer’s & target’s employees work as one
For years, only 15% to 30% of all projects have been successful. However, if you invest in change management from the outset, alongside project management, you can achieve a 95% chance of success.
Many skilled workers leave companies during change processes. And it’s usually the best ones who go. However, if you convince your experts of the change, motivate them, and build trust, you will keep them.
In most change initiatives, performance of employees declines first, followed by organisation’s productivity. By up to a quarter. Those who manage their change professionally avoid these losses.
Those who take a strategic approach to change communication ensure transparency, promote acceptance, and strengthen employees’ trust in change. It also eases the commitment of middle management.
Thanks to careful preparation (viadoo’s 4-Phase Model), everyone in the project team knows the shared vision, the reasons for the necessary change, their tasks, and their sponsors (!). This creates motivation for the work.
Investing in professional change management automatically trains your managers in this discipline. At the same time, a network of change agents is created so that future changes are also successful.

In order for organizations (entire companies or individual departments) to be successfully merged or integrated, the workforces must grow together. This cannot be ordered. The art lies in helping people overcome their primal social instincts. These include forming packs, setting boundaries, and reinforcing contrasts as part of what we call the Anti-Change-DNA phenomenon.
It is therefore essential to understand the cultures of the organizations involved in the merger or acquisition. This includes their unwritten values and behavioral standards that people live by in their everyday lives. The boundaries that employees set between their organization and others, and the resulting sense of identity, are also part of the culture (btw: third level of Edgar Schein‘s cultural level model).
As the human side of transformation, viadoo Change Guides specialize in identifying the cultures of organizations (companies, departments, teams) and actively supporting them in overcoming primal human instincts. Our services therefore include, among other things:

The communication strategy for post-merger integration must be in place by Day-One at the latest. From then on, it is important to keep internal and external stakeholders constantly up to date. For listed companies, this must be done in close coordination with the legal and investor relations departments. Often, there are not enough internal resources available for systematic change communication, which must also be coordinated with the team responsible for the technical aspects of post-merger integration.
This is where viadoo Change Guides come in: Communication is a cornerstone of our company. For 20 years now, we have been developing and implementing communication strategies for top managers in SMEs and DAX 40 companies so that they can successfully and sustainably achieve their change projects. This is especially true for PMI projects, where professional, early, and transparent communication can alleviate fears, strengthen the sense of belonging, and build trust.
Among other things, we offer the following live communication formats for successful post-merger integration:
