S&OP, or Sales and Operations Planning, is one of the most important processes in a modern supply chain and one of the most commonly misunderstood. If you are hiring into this area, or trying to work out whether your business needs to, it helps to understand what S&OP actually is before you write a job specification around it. This is a plain-English explanation, followed by what it means for the people you hire.
The short definition
S&OP is a structured, usually monthly, process that brings sales, marketing, finance, operations and supply chain together to agree a single plan that balances what customers are expected to want against what the business can realistically deliver.
That is the whole point of it: one plan, agreed across departments, rather than sales working to one set of numbers, operations to another and finance to a third. When those numbers disagree, which they almost always do, S&OP is the process that reconciles them into a version everyone commits to.
The problem S&OP exists to solve
In a business without a functioning S&OP process, each department tends to plan in isolation. Sales forecasts optimistically because ambition is rewarded. Operations plans conservatively because it carries the cost of getting caught short. Finance holds a budget that may bear little relation to either. Everyone is working hard, and the plans do not add up.
The consequences are familiar: too much stock of the wrong things and not enough of the right ones, expensive last-minute production changes, premium freight to recover missed availability, and a persistent gap between the sales forecast and what actually happens. S&OP exists to close that gap by forcing a single, reconciled plan on a regular cadence.
How the S&OP process actually works
Most mature S&OP processes run as a monthly cycle with five recognisable stages. The names vary between businesses, but the sequence is consistent.
Data gathering. The cycle starts by pulling together the previous month’s actuals: what sold, what was produced, where inventory sits, how accurate the last forecast turned out to be. This is the factual baseline everything else builds on.
Demand review. Sales, marketing and demand planning agree the best view of future demand, factoring in promotions, seasonality, new product launches and known market shifts. The output is a single demand forecast the business genuinely believes in, not a wish list.
Supply review. Operations and supply chain assess whether that demand can actually be met: production capacity, supplier lead times, inventory positions and any constraints. Where supply cannot meet demand, the gaps and options are documented rather than hidden.
Pre-S&OP reconciliation. This is where the real work happens. A cross-functional group reviews the gaps between demand and supply, models the alternatives, works out the financial implications of each, and prepares clear recommendations. Most decisions are resolved here; the genuinely difficult trade-offs are escalated.
Executive S&OP. Senior leadership reviews the recommendations, resolves the trade-offs that could not be settled below them, and signs off a single agreed plan, often described as “one set of numbers”, that the whole business then executes against until the next cycle.
S&OP, IBP and where the terms overlap
You will often see S&OP mentioned alongside Integrated Business Planning, or IBP. IBP is essentially a more advanced, more strategic evolution of S&OP: it extends the same reconciliation discipline further into financial planning and strategy, typically over a longer horizon of two to three years rather than the nearer-term operational focus of classic S&OP. The Institute of Business Forecasting & Planning treats both as part of the same professional discipline, and in practice many businesses use the terms loosely or interchangeably. For hiring purposes, what matters is less the label than how strategic and how cross-functional the actual role is.
Why S&OP is hard to do well
The mechanics of S&OP are not complicated. The difficulty is entirely human. A good S&OP process requires sales to commit to a number they can be held to, operations to be honest about what they can deliver, and finance to reconcile both against the budget, all in the same room, every month, without it descending into blame.
That is why S&OP so often exists on paper but not in practice. Businesses implement the meetings and the spreadsheets and still do not get the benefit, because the process runs but the honest reconciliation does not. It is telling that the IBF’s professional training in this area focuses as heavily on consensus-building and cross-functional facilitation as on forecasting technique. Which is precisely why the person running it matters so much.
What this means for hiring
Understanding the process makes it much clearer what an S&OP hire actually needs to be, and it is rarely what the job title implies.
The core of the role is not forecasting or planning technical skill, though both help. It is cross-functional facilitation: the ability to sit between sales, finance and operations, challenge an over-optimistic sales number and an over-cautious supply position in the same meeting, and hold the room while doing it. The strongest S&OP professionals are credible with a sales director and a factory manager alike, which is a genuinely uncommon combination.
This is why a brilliant technical demand planner is not automatically a strong S&OP hire. The skills overlap but are not the same, and promoting a strong forecaster into an S&OP role without checking for the influencing side is a common and expensive mistake.
The job titles this sits behind
S&OP responsibility appears under a range of titles, and reading past them matters. An S&OP Analyst or S&OP Coordinator typically supports the cycle, preparing data and materials. An S&OP Manager owns and runs the monthly process directly, chairing the meetings and holding functions to account. A Head of S&OP or Director of Integrated Business Planning owns the process at a strategic level, often building or maturing it rather than simply operating it, and increasingly sits close to or within the senior leadership team.
Confusingly, S&OP is also frequently folded into broader roles: a Head of Supply Chain or Supply Chain Director may own the S&OP process as one part of a wider remit, and a Head of Demand Planning brief may in practice be an S&OP leadership role. This is exactly why S&OP recruitment benefits from being clear about the actual scope rather than relying on the title.
How we approach S&OP recruitment
As a specialist supply chain recruiter, we start an S&OP search by establishing what the role genuinely is: whether it is building a process from scratch or running an established one, how strategic versus hands-on it is, and where it sits in the organisation. Those questions shape the candidate profile far more than the job title does.
