Operational improvement in private equity means raising a portfolio company's earnings and cash generation by changing how the business is run, rather than by paying a lower entry multiple or loading it with more debt. In practice it comes down to four levers that appear in almost every operational value creation plan: working capital, procurement, headcount and pricing. Understanding what each lever does, how large it typically is, and crucially which of them affects EBITDA and which only affects cash, is one of the most reliably tested areas in private equity interviews at associate level and above.
This article explains the concept and the four levers. If you want the numbers worked through end to end, the companion case Operational Improvement: What Aurelius Does quantifies a full plan on a €400m-revenue industrial carve-out, and the applied walkthrough How to Quantify an Operational Improvement Plan in a PE Interview takes you through the calculation sequence step by step.
Why Operational Improvement Became the Main Value Creation Lever
For most of the history of the leveraged buyout, returns came from three sources: financial engineering, multiple expansion, and earnings growth. Financial engineering meant leverage — buying a business with as much debt as lenders would provide, letting cash flow repay that debt, and handing the sponsor a larger share of a broadly unchanged enterprise value at exit. If you are new to that mechanic, what a leveraged buyout is and why leverage increases returns covers it from first principles.
Two things eroded that model. First, entry multiples across most of European and North American private equity rose materially over two decades, which mechanically compresses the return available from buying cheap. Second, debt markets became efficient enough that any sponsor could access broadly the same leverage on broadly the same terms, so leverage stopped being a source of competitive advantage and became table stakes. Multiple expansion, the third lever, is largely outside the sponsor's control — it depends on where the market is trading at exit, which is why disciplined investment committees refuse to underwrite it. If you want to see how that lever is isolated and measured, read what multiple expansion in private equity actually is.
What remains is EBITDA growth, and within EBITDA growth, the portion that comes from running the business better rather than simply riding a growing end market. That is operational improvement, and it is now where most large sponsors build their differentiation, with in-house operating partners, portfolio operations groups and sector-specialist advisors. For turnaround and special situations investors — the archetype includes firms like Aurelius, Mutares and Orlando Capital in the German-speaking market — operational improvement is not one lever among several; it is the entire investment case. These firms deliberately buy underperforming, non-core divisions at low multiples precisely because the margin gap to peers is the return.
The Four Levers of an Operational Value Creation Plan
An operational improvement plan is not a vague commitment to "improve efficiency". It is a quantified schedule in which each initiative has a euro value, an owner, a start date and a run-rate delivery date. Almost every such plan draws on four levers.
1. Working Capital: The Cash Lever
Working capital optimisation releases cash that is trapped in the balance sheet. A business that collects from customers in 73 days, holds 79 days of inventory and pays its suppliers in 49 days is financing its customers and its warehouse out of its own pocket. Tightening days sales outstanding (DSO), days inventory outstanding (DIO) and extending days payable outstanding (DPO) toward peer benchmarks converts that trapped cash into available cash.
The mechanics matter, and they are covered in detail in what net working capital is and how the cash conversion cycle works. The version an interviewer wants from you is short: net working capital equals receivables plus inventory minus payables, each of those three lines can be expressed in days against its natural driver, and each day removed releases a calculable amount of cash. Practise the day-count mechanics on the Working Capital Deep Dive case before you attempt a full operational plan.
Two properties of this lever are constantly tested. It is one-time, not recurring: you can take DSO from 73 days to 55 days once, and the cash arrives once. And it is cash, not earnings: a working capital release changes net debt and therefore equity value, but it never appears in the EBITDA bridge. More on why that distinction decides interviews below.
Non-core divisions of large groups are unusually rich in this lever, for a simple organisational reason: nobody in the division was ever measured on cash. The parent group managed cash centrally, the division was judged on revenue and margin, and so receivables, inventory and payables drifted for years without anyone owning them.
2. Procurement: The Highest-Quality Earnings Lever
Procurement savings reduce the cost of materials, components and bought-in services without touching volume, which means they flow to EBITDA at a full margin. That makes procurement the cleanest of the four levers and the one lenders will underwrite most readily. Typical initiatives are supplier consolidation, competitive re-tendering of categories that have never been tendered, specification harmonisation across product lines, and moving from spot buying to framework agreements.
The discipline in modelling this lever lies in two numbers. The first is the addressable share of spend: components that are sole-sourced, single-qualified for regulatory reasons, or under a long-term contract that does not expire inside the plan period cannot be re-tendered. In an industrial business, 60% to 75% of materials spend being addressable in year one is a realistic range. The second is the savings rate on that addressable spend, which for a business that has genuinely never run an independent tender might be 4% to 7%, and for a business already professionally managed might be 1% to 2%. The classic candidate error is to apply a headline savings rate to total spend, which inflates the lever by roughly the inverse of the addressable share.
Procurement also interacts with the working capital lever, and the interaction runs the wrong way. Pushing suppliers from 49 days to 65 days weakens your negotiating position on price at the same moment you are asking them for a discount. A credible plan acknowledges that tension rather than modelling both levers at full value in isolation.
3. Headcount: The Lever You Have to Buy
Headcount reduction is the most visible and most politically difficult lever. In a carve-out it is also frequently the largest, because the divested business inherits duplicated indirect functions: it needs its own finance, HR, IT and legal capability, but the transitional services agreement with the seller and the interim over-resourcing typically leave more people in place than the standalone business requires. Removing positions in indirect and administrative functions has the useful property of not affecting output, and therefore not affecting revenue.
Three modelling points recur in interviews. Use fully loaded cost per employee, not gross salary — employer social contributions, pension provision and facilities cost push the true figure roughly 25% to 35% above base pay in a German industrial setting, and using salary alone understates the saving badly. Second, the saving has to be bought: severance, works council negotiation and one-time implementation cost land in cash, typically at or shortly after closing, roughly twelve months before the full run-rate benefit arrives. Third, the cash cost of restructuring is normally funded at close out of the sources and uses table rather than out of operating cash flow, which is why it shows up as a use alongside the purchase price. If sources and uses is unfamiliar territory, the Sources and Uses Table case is the place to start.
4. Pricing: Fast, Powerful and Easy to Model Wrongly
Pricing is the fastest lever to implement — a price list can change in weeks, whereas a procurement tender takes months and a headcount reduction takes a works council process — and it has the most attractive arithmetic of the four, because a price increase flows to EBITDA at a 100% margin. Nothing costs more to produce; you simply charge more for it.
The offsetting risk is volume attrition, and here the asymmetry is the whole point. When a customer leaves, you lose the revenue but you also stop incurring the variable cost of serving them, so the EBITDA you forgo is only the contribution margin on that revenue, not the revenue itself. On a 25% contribution margin, a 3.5% price increase survives a very substantial volume loss before it turns EBITDA-negative. Candidates who deduct full lost revenue from EBITDA conclude that pricing is dangerous; candidates who apply the contribution margin conclude, correctly, that it is usually the most attractive risk-adjusted lever available.
Where pricing power sits is a commercial question rather than a financial one. In industrial businesses it typically sits in the aftermarket — spare parts, consumables and service contracts on an installed base, where switching costs are high and the price is a small fraction of the cost of downtime. Identifying that pocket is a core output of commercial due diligence, which is one reason private equity due diligence sequences commercial, financial and operational workstreams the way it does.
The Distinction That Decides the Interview: Cash Versus Earnings
If you take one thing from this article, take this. Three of the four levers — procurement, headcount and pricing — improve EBITDA. One of them, working capital, does not. It improves cash.
The consequence is structural, not semantic. Enterprise value at exit is the exit multiple applied to run-rate EBITDA. If you put a €48m working capital release into the EBITDA bridge and then apply a 5.0x exit multiple, you have credited the sponsor with €240m of value for €48m of one-time cash. The working capital release belongs one level further down the return calculation: it reduces net debt, and net debt is deducted from enterprise value to reach equity value. A recurring €1 of EBITDA improvement is worth the exit multiple; a one-time €1 of cash release is worth €1. Understanding the difference between enterprise value and equity value is what makes this distinction feel obvious rather than arbitrary.
This is also why an operational plan is presented to an investment committee as two separate exhibits: an EBITDA bridge showing the recurring earnings levers, and a cash bridge or net debt walk showing the balance sheet effects. Combining them into a single "value creation" number is the single most common way a candidate signals inexperience.
How the Plan Is Presented and Held To
Once quantified, an operational improvement plan stops being an analytical exercise and becomes a governance instrument. It becomes the operating budget management is held to, the baseline against which the management equity ratchet pays out, the evidence pack lenders use to size debt, and ultimately the input to the exit story.
The exit story is the value creation bridge, which decomposes the total equity gain into EBITDA growth, multiple expansion and debt paydown. A sponsor that can show most of its return coming from the EBITDA growth column, and can trace each euro of that growth back to a named initiative delivered on schedule, is telling the next buyer and its own limited partners that the return was earned rather than borrowed or timed. Work through the Value Creation Bridge case to see how the decomposition is built.
Plans also differ sharply by sector, which interviewers use to test whether you have a playbook or a template. In an industrials buyout, working capital and procurement dominate because the balance sheet is heavy and the input spend is large. In a software buyout there is almost no inventory, procurement spend is small, and the levers shift to pricing, packaging, net revenue retention and sales efficiency. The Tech Buyout vs. Industrials Buyout case works through exactly that contrast, and the screening criteria in What Makes a Good LBO Target explain which business characteristics make an operational plan credible in the first place.
What Interviewers Are Actually Testing
When an interviewer asks you to talk through an operational improvement plan, they are checking four things at once.
Whether you can separate cash from earnings. This is the pass/fail gate described above, and it is checked first because everything downstream depends on it.
Whether your assumptions are benchmarked or invented. A 6% procurement saving on 70% of spend is defensible if you can say where both figures came from — a spend cube, a pilot tender, prior carve-out experience. A 15% saving on total spend is not defensible under any framing.
Whether your endpoint is credible. A plan that takes a business from a 3% EBITDA margin to the bottom of a 9% to 12% peer range is a plan. A plan that takes it to 15% is a pitch. Investment committees discount the second heavily, and interviewers expect you to sanity-check your own output against peers before presenting it.
Whether you phase. Real plans do not deliver run-rate benefit on day one. Procurement savings arrive as contracts roll, headcount savings arrive after consultation concludes, pricing arrives at the next contract renewal cycle, and the working capital release typically lands over twelve to eighteen months. Quoting an internal rate of return built on instant delivery, without flagging the assumption, is the difference between a good answer and a naive one. The return mechanics themselves are covered in MoM versus IRR, the two return metrics every private equity investor tracks.
Where to Go Next
Operational improvement is a concept that only becomes real once you have sized the levers yourself. The natural next step is the Operational Improvement case study, which gives you a €400m-revenue industrial carve-out at a 3.0% EBITDA margin, a full set of balance sheet and cost inputs, and asks you to quantify all four levers, build the EBITDA bridge, and carry the plan through to a money multiple and an IRR. If you would rather see the calculation sequence explained first, the applied companion piece walks through each step in order, including the two arithmetic traps that catch most candidates.
