Synergies, growth, economies of scale, elimination of duplicate structures, accelerated innovation, competence building. The list of goals for mergers and acquisitions (M&As) is long. Unfortunately, the list of failed M&As is just as long. 80% 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 with the strategic planning and successful management of their Post-Merger Integration (PMI).
Our proven M&A integration approach
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 specializes 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:

Our services along a typical merger integration
Due Diligence Phase
- Cultural Due Diligence, 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.
Due Diligence Initiation
Signing
Transition Phase
- Reviewing the due diligence report(s) to identify the issues to be addressed during the integration process.
- Developing a PMI Architecture and a PMI Communication Strategy.
- Establishing a strong Integration Management Office (IMO) team with an integration committee and transversal integration teams (e.g. IT system integration, HR topics).
Post Day One Integration Phase
- 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).
Closing & Day One
First 100 Days
- 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.
Business as Usual Phase
- After 12 – 18 months cost-saving synergies begin to capture
- After +36 months culture changed successfully, buyer’s & target’s employees work as one

Top 5 benefits of partnering with PMI experts
External objectivity
External PMI partners bring an independent perspective on the organization, culture, processes, and areas of conflict. This makes risks, tensions, and blind spots visible more quickly.
Cultural integration
Many integrations fail because of differing work styles, leadership philosophies, and corporate cultures. External partners help identify cultural differences early on and translate them into shared behaviors in a targeted manner.
Proven methodology
Professional PMI partners work with proven integration models, clear roadmaps, and structured decision-making processes. This reduces complexity and provides direction during a phase of high uncertainty.
Faster implementation
Post-merger integrations are often subject to tight deadlines. External partners accelerate implementation by clarifying priorities, structuring actions, and establishing clear lines of responsibility.
Relief for management
During the integration process, executives must continue to manage day-to-day operations. External PMI partners take over the coordination, facilitation, and management of key integration tasks, thereby freeing up time for strategic leadership.
Frequently asked questions
Post-merger integrations rarely fail because there was no strategic rationale for the transaction. Problems often arise during operational and cultural implementation: unclear decision-making authority, conflicting management approaches, parallel processes, differing work styles, or a lack of direction among employees and managers. It is especially after the signing or closing that it becomes clear whether synergies can actually be realized. A successful PMI therefore requires not only an integration plan, but also a clear operating model, robust governance, consistent stakeholder management, and communication that reduces uncertainty and enables decisive action.
Cultural due diligence analyzes cultural differences between the buyer, the target company, and, if applicable, other involved organizational units. This is about critical questions regarding integration capability: How are decisions made? How is leadership exercised? To what extent are control, autonomy, speed, risk tolerance, or customer focus emphasized? What values are officially communicated, and which behavioral patterns actually shape day-to-day operations? Cultural due diligence helps identify cultural risks early on, plan integration measures realistically, and avoid friction-related losses later on.
A “clash of cultures” describes the collision of different organizational cultures following a merger or acquisition. This can manifest as conflicts between leadership teams, mistrust of the new organization, declining motivation, losses in productivity, or the departure of key employees. Typical triggers include differing leadership styles, decision-making processes, communication patterns, understandings of performance, or the identities of the companies involved. It is crucial not to ignore cultural differences or merely gloss over them through communication. They must be made visible, contextualized, and actively addressed.
An Integration Management Office (IMO) centrally manages post-merger integration and ensures that strategy, synergy goals, work packages, decisions, and communication remain aligned. It coordinates integration streams, tracks milestones, risks, and synergies, prepares decisions for steering committees, and establishes a clear escalation process. An effective IMO is the steering body of the integration: it creates transparency, prioritizes critical issues, connects functional areas and management levels, and ensures that the integration does not get lost in day-to-day operations.
Cultural change in a PMI does not arise solely from new value statements or communication campaigns. It becomes effective when desired behavior is embedded in leadership, decision-making, structures, processes, and routines. Suitable methods include cultural assessment, leadership alignment workshops, culture target picture, change impact assessment, stakeholder mapping, communication architecture, leadership empowerment, dialogue formats, sounding boards, pulse checks, and the translation of cultural target visions into concrete leadership and collaboration principles.
