Sales & Operations Planning as Transformation

Getting S&OP right is a change in culture and cross-functional decision-making — not a systems project. Lessons from a turnaround.

A familiar struggle

Many companies wrestle with the same problem: keeping supply and demand in balance. When they can’t, the symptoms are predictable — service levels slip, inventory turns sag, functions turn on one another, and people and assets get burned on rework. All of it lands on both the top and bottom line. The frustrating part is that most of these companies already run something they call S&OP. It simply isn’t working.

A turnaround, in brief

Consider a large consumer-products manufacturer. Its monthly planning cycle had become a blame game: sales pushed operations to do better, while operations faulted sales for late and inaccurate demand signals. Each function worked from its own numbers, so there was never a single forecast or one version of the truth. Production lurched from directive to directive, service kept falling, and the financials followed. No one could see across the process, and no one agreed on the root cause.

Leadership finally called a full stop. During a slower stretch, they pulled every key functional leader into a mandatory off-site — devices away, armed with a shared fact base — to diagnose root causes and agree on fixes. Two days later they left with a high-level roadmap and a short list of actions everyone had signed up to. The hard part, execution, came next. About fourteen months on, the same company was a best-practice performer. Nothing about the software had changed; what changed was how the organization planned together.

S&OP is a transformation, not a tool

This is the heart of it. S&OP exists to connect demand and supply — a cross-functional, monthly rhythm for reaching consensus on one operating plan that finance, sales, and operations all use. But it runs on human interaction far more than on process maps or software; technology and process are enablers, not the point. The company in our story already had the meetings, the roles, and the process documents. What it lacked was two-way communication, a shared fact base, and the visibility to act before the least-costly moment had passed. Fixing S&OP was not a systems project — it was a change in culture and behavior, which is exactly why it took genuine executive will and more than a year to make it stick.

S&OP improvement is less about following prescribed steps than about changing the culture and behavior of how a company plans.

Ten lessons from the turnaround

Getting started

The lesson beneath the lessons is that S&OP improvement is a change-management effort, not a sequence of process steps. Start by documenting the current state honestly and naming the biggest gaps. Put an executive sponsor and a small steering committee in place. Establish baseline metrics — and the few that matter most to customers. Then sequence the rollout, and resist a pre-set timeline, because every organization’s problems and starting point differ. The payoff is real: our manufacturer went from firefighting to best practice by keeping its focus on the right metrics and driving execution until the new behaviors became routine. Done that way, S&OP stops being a monthly battle and becomes a durable engine for performance.
