The S&OP review most mid-market companies get wrong

If your monthly S&OP meeting spends most of its time reviewing what already happened, it isn't an S&OP meeting. It's a status report with a bigger invite list. Here's the difference — and how to fix it.

Walk into a typical mid-market S&OP meeting and you'll see a familiar scene. A deck of thirty slides. Someone reads last month's sales versus plan. Heads nod. A chart shows inventory is up. Someone says "we need to watch that." Two hours later everyone leaves, the numbers unchanged, and nothing has actually been decided.

That meeting feels productive. It is almost entirely wasted. The problem isn't effort or attendance — it's that the meeting is pointed in the wrong direction: backward, at what happened, instead of forward, at what to do about what's coming.

S&OP is a decision forum, not a reporting forum

The entire purpose of Sales & Operations Planning is to make a small number of cross-functional decisions that individual departments can't make alone: where demand and supply disagree, and someone has to choose. Do we build ahead for a demand signal we're not sure of? Do we protect the launch or the base business when capacity is tight? Do we accept the sales upside in the plan, or hold the line?

Reviewing the past has exactly one legitimate job in S&OP: to inform those forward decisions. The moment the review of history becomes the point of the meeting rather than the setup for it, you've lost the plot.

A good S&OP meeting is measured by the quality and number of decisions it makes — not by the completeness of the deck it presents.

The four symptoms of a broken review

• It's backward-looking. More than a third of the time goes to explaining variance that's already happened and can't be changed.
• It's comprehensive instead of exception-based. Every product, every region, in equal detail — which means the 5% that actually needs a decision drowns in the 95% that's fine.
• It ends without owned actions. Concerns are "noted." Nobody's name and no date is attached to anything.
• Last month's actions are never checked. So the same issues resurface, cycle after cycle, and the meeting has no memory.

What a decision-driven review looks like instead

You don't need a new system to fix this. You need to invert the meeting.

Lead with exceptions, not the full portfolio. The pre-work — done by the planner before anyone gathers — is to surface the handful of places where demand and supply disagree, where the forecast has drifted, where inventory is heading out of bounds. The meeting starts there. Everything that's on track gets a single green line and no airtime.

Frame every item as a decision, not an update. Not "sales of product X are down 12%." Instead: "product X is tracking 12% below plan; do we cut the build and free the capacity for Y, or hold in case it recovers? Recommendation: cut. Decision needed today." The planner brings a recommendation; the room decides.

Look forward across the whole horizon. The value is in the months you can still influence, not the one that just closed. Most mid-market teams review last month in loving detail and barely glance at the quarter they can still change.

Close every decision with an owner and a date, and open the next meeting by checking them. That single habit — a live action log reviewed at the top of every cycle — is what gives an S&OP process a memory and turns it from theatre into governance.

The role of accuracy in the room

One more shift separates the good reviews from the rest: they bring forecast accuracy and bias into the meeting as a standing input, not an afterthought. If the room is about to bet production on a number, it deserves to know how reliable that number has been. A consensus forecast with a known 8% high bias in that category should be discounted in the decision — out loud, in the room. When accuracy is invisible, the loudest voice wins. When it's on the table, the evidence does.

None of this requires more meetings or more slides. It usually requires fewer of both. The mid-market companies that get real value from S&OP aren't the ones with the fanciest tools — they're the ones whose monthly review reliably produces a short list of owned, forward-looking decisions, and then checks that they happened. That's the whole game.
