Mergers and acquisitions promise growth, scale, and synergies. But too often, those ambitions are lost in execution. The culprit isn’t usually strategy. It’s integration—where decisions about systems, data, and vendors directly impact whether value is captured or eroded.
And at the heart of it all is IT.
When underestimated, IT becomes a bottleneck: misaligned platforms, redundant applications, fragmented data, and disrupted operations. But when managed strategically, IT becomes the backbone of post-merger value realization—linking business objectives with operational reality.
The question isn’t whether IT supports the integration. It’s how IT drives the success of the integration.
By the Numbers: Why IT Matters
*Statistics from recent McKinsey & Company research
Consider a cross-border merger of two B2B software companies.
Challenge: Completely different IT ecosystems. One company fully on AWS, the other on Azure, each with dozens of overlapping SaaS tools.
Approach: Using our integration framework, we built a unified cloud strategy, rationalized 48 applications down to 21, and migrated core systems in under 120 days.
Impact: $4.7M in annual run-rate savings, avoided costly vendor penalties, and enabled single sign-on for 96% of employees within 90 days.
This wasn’t just an IT win—it was a business win, accelerating synergies and improving the employee experience.
The sooner IT is involved, the better. In fact, waiting until the post-merger integration phase is already too late. Real IT due diligence before Day 1 ensures that:
IT diligence is no longer optional—it’s essential for protecting deal value.
Many organizations still approach post-merger integration with outdated assumptions about technology.
The result? Business units frustrated by poor performance. Shadow IT filling gaps. And the synergies promised in the deal thesis slipping further out of reach.
Through years of supporting integrations, we’ve seen a pattern: the companies that succeed put technology at the center of their approach.
Our framework is built around five core pillars:
Digital Value Alignment– Identify which IT capabilities are essential to deliver on the deal’s strategic objectives.
IT Operating Model Design – Define decision rights, governance forums, and architectural principles up front.
Application & Infrastructure Rationalization – Consolidate redundant platforms across cloud, on-prem, and hybrid environments.
Vendor & Contract Strategy – Rationalize licenses, consolidate vendors, and renegotiate contracts to unlock value.
Data Integration & Integrity – Ensure accurate, unified data to support decision-making across the enterprise.
Even with the right strategy, integrations often falter in decision gridlock:
CIOs are pulled in different directions—cut costs, integrate quickly, modernize for the future—without a clear roadmap to balance trade-offs. The result: scope creep, spiraling costs, system outages, and declining user trust.
The solution isn’t over-engineering. It’s clarity.
Our approach relies on accelerators and playbooks that bring order to chaos. Systems and data flows are mapped visually. Critical path risks are flagged early. Decision forums are designed to prevent endless debate.
And instead of governance sitting apart from delivery, roles like Scrum Masters and Delivery Managers are embedded into vendor teams. They act as gatekeepers for scope, ensuring day-to-day work remains aligned with integration objectives.
This combination—structured playbooks plus embedded assurance—enables organizations to move decisively while still managing complexity.
A focused pre-close diligence sprint reduces surprises, informs valuation, and prevents costly transition missteps. Use this as a pragmatic starter checklist (adapt to deal size and risk):
How to put this into practice - Run a 2–3 week rapid scan with risk/cost/value heat‑maps - Pre‑negotiate vendor terms before signing - Lock a Day‑1/30/90 plan before close.
TSAs can protect operations immediately post‑close—but bad TSAs leak value. Design for clarity, cost control, and exit from day one.
Scope & Service Catalog - Enumerate services with explicit inclusions/exclusions and baselines
Pricing & Commercials - Use metered fees with step‑down schedules and extension premiums
Performance & Governance - Include SLAs/OLAs, escalation paths, and a joint TSA PMO
Security & IP - Define data‑sharing, logging, access, and IP ownership
Exit Planning - Tie line items to exit criteria, schedule dress rehearsals, and require knowledge transfer
How to put this into practice - Target 6–12 months TSA duration with a monthly exit scoreboard - Hold monthly commercial reviews; renegotiate early if variances exceed thresholds.
This approach creates value across multiple stakeholders:
Post-merger integration is never simple. But the organizations that succeed are those that recognize technology is not cleanup—it’s the engine of scale, synergy, and growth.
By embedding IT due diligence before Day 1 and carrying that discipline into post-merger integration, companies can move faster, avoid costly missteps, and realize deal value with greater certainty.
In M&A, IT doesn’t just support the integration. It makes the integration possible.
Your next deal depends on it.
