Why It Matters
Ignoring change management risks integration failure, eroding expected synergies and damaging employee morale. A structured approach safeguards value creation and accelerates post‑deal performance.
Key Takeaways
- •Dedicated change manager drives post‑deal value creation
- •Interviews and surveys uncover hidden cultural resistance early
- •Personalized action plans assign accountability across integration
- •Ongoing climate surveys measure integration health after six months
- •Early resistance analysis prevents synergy‑killing roadblocks
Pulse Analysis
M&A activity continues to surge, but the human side of integration often lags behind financial engineering. Executives recognize that the biggest corporate investment—acquiring another firm—introduces profound shifts in processes, technology, and culture. When change management is treated as a separate discipline, it brings analytical rigor to these soft factors, turning employee anxiety into actionable insight. By embedding a change manager early, companies shift from reactive firefighting to proactive value capture, ensuring that post‑deal objectives are not merely aspirational.
A practical change‑management framework begins with one‑to‑one interviews and focus groups, giving employees a voice and reducing siege mentality. Follow‑up surveys capture sentiments that may be hidden in face‑to‑face settings, creating a comprehensive data set for a stakeholder report. That report must include personalized calls to action, assigning clear owners to each integration task. A resistance analysis then spotlights potential deal‑killers—such as payroll schedule changes or cultural misalignments—allowing teams to prioritize low‑hanging fixes that quickly build momentum. This systematic approach, championed by experts like Dawn White, converts intangible cultural factors into measurable milestones.
The payoff of disciplined change management is tangible: higher employee retention, smoother cultural blending, and faster realization of synergies. Six‑month climate surveys provide a feedback loop, comparing pre‑integration concerns with current realities and prompting timely adjustments. Companies that institutionalize this practice report fewer integration delays and stronger post‑merger performance metrics. As M&A volumes grow, embedding change management into the deal lifecycle is no longer optional—it is a competitive differentiator that safeguards investment and drives sustainable growth.
How to Drive Change Management During M&A Integration
Transformation. Evolution. Revolution.
Whatever world you choose, there is no denying that M&A at its core is about change – for the acquirer and the target.
Even growth, the most commonly cited motive for undertaking M&A given by managers, is just a different word for change.
It’s a mystery, then, why the M&A community has largely overlooked the value of change management. This is a potentially costly oversight.
Where a business stands on the other side of change is ultimately a measure of how well it was managed.
The Change Manager Role
The easiest way to think of the change manager role is as a project manager, where the project is fundamental change for your organization.
The bigger the acquisition, the more processes, technology, job roles, structures and culture can (and indeed, should) change.
Traditional managers have neither the time nor the experience to oversee this transition, which is where change managers come in.
What is Change Management?
Change management is the process through which a company creates value from change. It takes an analytical approach and considers all of the areas which traditional M&A overlooks in the M&A process – from people and values to processes and technologies.
Underestimating the Power of Change
A well‑trodden maxim goes that the biggest investment anybody will make over the course of their lifetimes is their house.
And for a company?
If we’re talking about one‑time investments, invariably the biggest investment that a company will ever make involves some element of M&A. That is as true for tech firms as it is for the thousands of medium‑sized firms whose deals fill Capital IQ every year.
And yet, despite the transformative impact that M&A has on businesses of all sizes, change management is almost never mentioned. Perhaps managers equate the acquisition of companies with that of capital expenditure – a balance‑sheet addition.
Whatever the reason, it’s a potentially disastrous mistake to make. Having had privileged access to the inner workings of thousands of deals, we believe that change management deserves a role all on its own in the M&A process.
As competent as you believe your office manager or HR director to be, you can’t put them in charge of change management. Nor is it good enough to say that it’s a “collective responsibility.” Being serious about M&A involves creating a dedicated change management role.
This could be a hired hand brought on board for an extended period, or someone who will fulfill the role over a series of acquisitions that your company is planning. Bringing someone of this nature onto your M&A team has several benefits:
-
Within your business, having a dedicated role for change creates a culture prepared for M&A. It moves from being a process based on ad‑hoc procedures to one where the goal is to maximize value at every stage of the process (particularly after the deal has closed).
-
Outside the business, the presence of a change management officer creates a smoother relationship between the buyer and its targets, before, during and after any transaction has taken place.
Perhaps this is best captured by renowned change‑management expert Dawn White, who says that when it comes to change management: “Methodology is the driver.”
Methodology Is the Driver
Putting Dawn White’s advice into practice, we recommend that companies implement some variant of the methodology that DealRoom has constructed (see below), which is based on findings from thousands of deals.
This constitutes change‑management best practice and should include:
-
Set up one‑to‑one interviews and focus‑group sessions.
-
Use surveys to find the big picture.
-
Produce a comprehensive report of your findings and present it to stakeholders.
-
Ensure the report includes personalized calls to action.
-
Conduct a potential resistance analysis.
Let’s now take a detailed look at these points in order.
1. One‑to‑one interviews and focus‑group sessions with the target company
Nothing sends shockwaves through a group of employees like telling them that their company is being acquired. The mere mention of another firm on the horizon can create a siege mentality among target‑company employees, who start to wonder whose job is first to go.
Facetime between these employees and the change manager reduces this anxiety, bringing a more human aspect to the process. Employees who may have become hostile, or even left the target company, can be won over to the new vision being proposed.
Interviewing a broad swathe of employees – from top to bottom – allows the change manager to learn about the company’s internal workings, its culture and possible problems that would otherwise remain hidden.
2. Use surveys to flesh out the big picture
What people may be reluctant to put across in a face‑to‑face meeting, they are more willing to express in a confidential survey that allows them to vent their emotions. A well‑designed survey should draw out insightful answers.
For example, suppose one of the employee concerns that came up repeatedly during your interviews was the lack of opportunities for promotion. Structure the survey around this. Ask questions like “How can you contribute more to the company?” and “How could we value your contribution more than it is being valued now?”
Well‑thought‑through surveys will build on the interview findings to paint a clearer picture of what’s going on.
3. Produce a comprehensive report of your findings and present it to stakeholders
By now you should have insightful findings to present to stakeholders within the acquiring firm.
The report may highlight issues such as knowledge gaps, cultural problems, or other “soft” (human) issues that, left unchecked, could derail deals.
Present the positives and negatives in clear terms:
“The positives we see in acquiring this firm are _____________ while we are somewhat concerned about _________________.”
4. Be sure the above report includes personalized calls to action
This is where the change‑management expert adds most value. Personalized calls to action assign responsibility (and thus accountability) to important tasks that might otherwise be sidelined. If drawn up – and implemented – this report becomes the basis for the company to drive value‑generating changes from this point on.
5. Conduct a potential resistance analysis
Similar to the face‑to‑face sessions, a resistance analysis lets both sides see what potential “value destroyers” exist within the organizations.
Avoid a “them and us” mentality. Instead, uncover what employees on each side are anxious about, what they see as negative points about the deal, and where they see their future roles. Creating a mood of transparency will almost certainly yield valuable insights.
Six months after the transaction, conduct a climate survey and present findings to executives
Repeat the earlier steps, but now with a post‑integration perspective. Compare the concerns raised six to nine months earlier with the current reality. The climate survey helps determine how everyone is adapting and what new concerns have arisen since the merger. Present the results to management for prompt action.
Why Change Management Is Often Forgotten in M&A
Because it is not tangible.
Traditional project‑management metrics are easy to see; change management’s impact is less obvious. When you start noticing what is not happening – people not embracing new culture, work not being done properly, synergies not being met – you realize change management has been neglected.
To combat this, M&A change management needs to be brought to the forefront and differentiated from project management. Change management cannot be thought of merely in terms of tasks and checkmarks; it must be seen as an approach that ensures people on both the acquiring and target sides are “taken care of” across all functions.
Using Change Management to Identify and Prioritize Roadblocks
“One of the areas in which change management can garner the largest impact is identifying deal and synergy killers.”
An impact analysis lets the change‑management team examine foreseen debt, operational‑style differences, and other benefits early on. Early identification allows mitigation, reducing the destructive power of roadblocks.
When early identification is not used as a weapon against roadblocks, small issues can later wreak havoc on a deal. For example, changing payroll from weekly to bi‑weekly can lead to retention problems if not managed properly.
Strategies for prioritizing and addressing cultural and change‑management issues
-
Look at what is high priority to employees and address it quickly – people are key.
-
Align roadblocks with the key objectives of your integration.
-
Identify low‑hanging fruit – simple issues that can be quickly rectified – to gain momentum.
Overall, consider impact and effort when deciding where to start. After fixing an issue, change‑management teams should check in with both sides to see if employees truly feel a difference.
Where and Why You Might Face Resistance
Employees from the target company may be resistant because they did not choose to join the acquiring firm. Common signs of resistance include:
-
Feeling that the acquiring company is of less value than theirs.
-
Lack of interest in being part of a new organization.
-
Perception that the acquiring company has not taken the effort to teach them about its structure, core practices, or how to succeed in the new environment.
These feelings can lead to acquired employees not bringing their full energy and talent to the table.
Conclusions
Just reading through this article, you can see many of the issues that arise during the integration phase. Imagine trying to conduct a deal without following the steps outlined above.
Change management is an ongoing process. Coming to terms with this and taking the necessary steps within your organization to accommodate change is the first step toward ensuring a successful M&A process.
