Evaluating Operational Synergies Post Merger: A Supply Chain Finance Leader’s View

Synergy gets talked about like it is a line item you can will into existence. In real integrations, it is closer to an operating system. If the operating model does not change, the numbers do not stick. That is why the most reliable teams treat synergy as a discipline of decisions, not a slide.

That matters because evidence is starting to separate teams who track value from teams who just forecast it. Deloitte has reported that companies that actively identify, track, and deliver synergies outperform deal targets by an average of 23. That is not magic. It is what happens when integration governance, finance ownership, and execution rhythms are designed to force clarity early.

Masha Chandrasekaran is the Head of Supply Chain Finance, Beauty & Wellbeing, North America at Unilever and a Business Intelligence BIG Innovation Judge. She has led finance program management and supply chain finance work across large transformations, with a focus on turning cost, volume, and margin levers into decisions teams can actually run.

Masha, when you get pulled into a merger integration, what is the first thing you build to separate real synergy from hope?

The first thing I build is a decision map that forces everyone to stop talking in abstractions. In my experience, synergy only becomes real when the work is broken into concrete deliverables with owners, timelines and a clear financial mechanism. I start by making the integration legible. That means separating work that actually creates value from work that leaks it, across systems transitions, vendor and customer readiness, master data and product costing. Once you do that, you stop debating synergy in principle and start testing it against operational choices and timing. That shift from a model that looks right to a program that lands is what I will be digging into as a confirmed speaker at the World Finance Forum in Philadelphia in May 2026.

How do you make that structure hold when there are too many stakeholders and too many moving parts?

You have to treat governance like a product that people rely on, not an admin ritual. I designed weekly cross functional reviews with dependency tracking, clear risk escalation and a simple rule that unresolved issues do not get buried in working group notes. They come back into the main forum until there is a decision.

In large integrations, the hard part is not effort. It is alignment under pressure. I focused on leadership alignment across supply chain, finance, IT and commercial teams so decisions stayed anchored to the future state, not to what was easiest for one function in the moment. When governance is done right, it does not slow the work. It prevents rework and protects the timeline.

Synergy is usually framed as cost. Where do cost, volume and margin actually come together in the model?

Cost, volume, and margin come together only when the network stops being treated as a black box and is modeled as a set of executable decisions over time.

On the supply chain side, I connect the financial mechanics to decisions teams can execute. That includes pressure testing capacity and demand trade offs over time, evaluating make versus buy choices and sizing consolidation moves across lanes and warehouses in a way that holds up when assumptions meet reality. Equally important, I assess whether the underlying processes and systems are defined clearly enough for two fundamentally organizations to operate as one. If the operating model cannot be executed consistently across different systems and ways of working, the modeled synergy will not translate into realized margin.

What does tracking look like once the deal is live, especially when the pressure is to move on?

Tracking has to be embedded into the operating cadence from day one; otherwise it degrades into narrative.

Once the deal is live, I hard-wire synergy tracking into existing business rhythms—monthly close, forecast updates and operational reviews, so progress is reviewed with the same discipline as core financial performance.
Each synergy is assigned a single benefit owner, a quantified run-rate target and a realization path tied to specific actions. Status is defined using simple, non-negotiable criteria—committed, in execution, realized or at risk—so progress cannot be reclassified through interpretation. Variances trigger predefined escalation thresholds that force decisions early, before slippage compounds.

This level of transparency is not just internal hygiene; it changes outcomes. BCG has shown that acquirers who publicly disclose synergy realization deliver approximately 6% higher relative TSR over the following two years. The takeaway is consistent with experience: when value is provable, it becomes manageable.

My work on the SARC editorial board for the Journal of Innovative Science, and the Sarcouncil Journal of Public Administration and Management, also reinforces this mindset. If you cannot trace the logic from claim to evidence, the claim does not survive scrutiny. Integration governance should be held to the same bar.

You have also led finance for major logistics and distribution changes. How do you keep service ambition from quietly diluting margin?

You have to build cost transparency before you scale the service promise. Otherwise, you are just moving faster into an unknown cost structure.
I approached it as a finance led cost to serve architecture and control discipline, not just a network redesign exercise. That meant re-baselining delivered cost across routes, warehouses and customer segments so leadership could see the tradeoffs clearly, then using that baseline to govern rollout choices and course correct when service or cost moved off plan.

It also meant treating controls as part of execution, not an afterthought. In large logistics changes, you have to maintain adherence to the financial control framework for capex and operating spend while also ensuring compliance with local warehousing, transport and labour regulations as the footprint changes. The point is not paperwork. The point is that when controls and auditability stay intact through change, teams move faster with fewer reversals, because decisions hold up when they get challenged.

When you look forward, what is changing about how supply chain finance leaders need to run these programs?

The pace of network change is accelerating, and finance has to be ready to govern that change without freezing it. Gartner reported that 73% of companies have made supply chain network changes in the past two years. If that is the reality, then integration capability and network redesign capability cannot be treated as occasional projects. They have to become repeatable operating muscles.

For supply chain finance, that means two things. First, decision quality has to improve, because speed without guardrails is how cost creeps back in. Second, governance has to stay practical. Models need to be usable in the forums where decisions are made, not just correct after the fact.

Finally, What advice would you give to someone trying to become the person who can be trusted with the hardest integration calls?

Build a reputation for making complexity easier to act on. People do not need more analysis. They need the next decision to be clear, and they need to know what evidence supports it.

I also think it helps to practice the discipline of review. My work as a SARC peer reviewer has made me more careful about what I claim and how I support it. In an integration, that same habit becomes a leadership skill. If you can explain what will change, why it will change, and how you will know it changed, you become the person teams trust when the stakes are high.

Ms. Chandrasekaran’s answers point to a simple truth that gets lost in ideal language. Synergy is not something you announce. It is something you operationalize. The teams that win are the ones who design decision cadence early, keep governance tight enough to prevent value leakage, and build tracking that produces evidence, not narratives. As integrations and network change become more frequent, finance leaders who can translate cost, volume, and margin mechanics into a program people can actually run will keep setting the pace.
