Summary
- M&A IT integration success can hinge on how early organizations identify technology dependencies and operational risks.
- Discovery, IT assessments, and TSA planning help reduce uncertainty and improve day-one readiness.
- Undocumented systems and shared services are among the biggest obstacles during integrations and divestitures.
- Experienced professional services teams help organizations move faster while maintaining business continuity.
When organizations prepare for a merger, acquisition, or divestiture, the focus is often on financials, legal agreements, and operational planning. However, M&A IT integration often determines whether a business can successfully separate, integrate, or operate independently on day one. Despite its importance, IT rarely gets the same level of attention early in the process.
Over the years, I’ve worked with organizations navigating complex transactions, and many of the same questions come up time and again from business and technology leaders. In this blog post, I answer some of the most common questions and share some lessons we’ve learned helping clients reduce risk, accelerate readiness, and avoid costly surprises.
Understanding the hidden risks
Why does IT become a blocker during mergers, acquisitions, and divestitures?
More often than not, organizations have far more dependencies than people realize.
Over the years, they build connections between applications, networks, security tools, management platforms, and business processes. Some of those dependencies are documented, but many aren’t. During a merger or divestiture, you’re suddenly trying to identify everything that has to continue working while also separating or integrating environments.
We often find systems that rely on infrastructure owned by another part of the business, tools for management, security, or supporting services that are shared across organizations, or older technologies that nobody has touched in years but are still critical to operations.
The challenge isn’t necessarily the technology itself, but rather uncovering all those hidden dependencies before they become a problem.
What do business leaders typically underestimate about IT complexity?
Typically, it’s the amount of coordination that’s required. People often assume the documentation exists and that everyone understands how the environment works. In reality, there are usually multiple teams involved, different standards across the organization, and key information that’s held by only a few people.
Something as simple as gaining access to systems can become a major challenge. You may need approvals from several different groups, and everyone has competing priorities.
One thing we’ve learned is that communication is just as important as technology. The faster you can bring stakeholders together and solve problems collaboratively, the faster the project moves.
Where do surprises typically emerge?
Undocumented dependencies are probably the biggest surprise. It’s very common to find systems, applications, or traffic paths that nobody realized were still in use. We also encounter older technologies that are out of support or require specialized expertise that can be difficult to find.
Another common challenge is access. During a divestiture especially, there can be multiple organizations involved, each with their own processes and priorities. If access isn’t handled early, it can quickly become a bottleneck. That’s why we spend so much time validating information rather than assuming the documentation tells the whole story.
Building a foundation for success
What does an effective discovery phase look like?
At GDT, the first thing we do is focus on the business goals. Before we talk about infrastructure, we want to understand what the organization is trying to accomplish. What applications are critical? Who uses them? What are the security requirements? What has to work on day one?
From there, we start identifying the applications, traffic flows, users, stakeholders, and dependencies that support those business requirements.
We also build high-level design documentation so everyone understands how the environment is supposed to function. That becomes the foundation for everything that follows.
What does an IT assessment actually involve?
Discovery tells us what needs to be supported. The assessment tells us what actually exists.
A lot of organizations believe their documentation is current, but once we start looking deeper, we often find gaps. Systems have changed, applications have been added, and configurations have evolved over time.
An assessment is where we validate everything. We’re looking at:
- Hardware
- Software
- Licenses
- Support contracts
- Network configurations
- Security controls
- Firmware versions
- Third-party dependencies
We want to understand not just what exists but how it’s configured and whether it’s following best practices.
Sometimes that’s done manually. Sometimes we use automated tools, like NetBrain. Sometimes we can leverage existing management platforms. In most cases, it’s a combination of all three. The goal is simple, though. We want to eliminate surprises before they impact the project.
What separates a successful TSA plan from one that creates new risk?
A successful TSA plan requires a clear understanding of application dependencies, shared services, stakeholder responsibilities, and transition timelines. If you don’t understand those things, you’re making assumptions, and assumptions usually create risk. You’ve really got to understand the environment before you start making decisions.
One of the biggest mistakes I see is prioritizing speed over design. Everyone feels pressure because the TSA clock is ticking, but if you don’t take the time to understand the environment, you’re much more likely to encounter issues later that delay the project or increase costs.
Moving fast without creating new risk
How do you balance speed with security and operational requirements?
The key is staying organized and keeping communication flowing. We work closely with stakeholders to understand TSA requirements, identify the most critical systems, and align everyone on the timeline.
From there, we determine whether temporary solutions are needed to meet key milestones while long-term work continues. We also leverage additional engineering resources so multiple workstreams can be assessed and executed in parallel.
Most importantly, strong project management and technical leadership keep everyone aligned. When internal teams, stakeholders, OEMs, and third parties are all working from the same plan, we can move quickly without compromising security or quality.
Why does having one partner across multiple technology areas matter?
Continuity matters. As we move through discovery, assessment, design, and execution, we’re constantly building knowledge about the environment. We understand the applications, the users, the dependencies, and the risks. If that knowledge gets handed off multiple times, things can get lost.
When the same team stays involved throughout the process, we’re able to build on what we’ve learned and make better decisions as the project progresses. That reduces risk and helps keep everyone aligned to a single plan.
Where do professional services create the most value?
The biggest value from professional services comes from bringing a structured process to a very complex situation. We’ve done enough of these projects to know where the common pitfalls are. We have established approaches for discovery, assessment, design, migration planning, testing, and execution.
Just as importantly, we know how to coordinate all the different stakeholders involved and keep everyone moving toward the same goal.
That’s often what makes the difference between a project that stays on schedule and one that struggles.
What’s the biggest lesson organizations should take away?
One of the most important things to do is to start earlier than you think you need to. Without a doubt, the organizations that have the smoothest transitions are the ones that invest in discovery and assessment up front. The more you understand your environment before execution begins, the fewer surprises you’ll encounter later.
At the end of the day, IT isn’t usually the reason a transaction happens, but it can absolutely determine how successfully that transaction gets completed.
