S&OP: why Italian SMEs don't do it (and how much they lose every day)

The symptom you see in every SME

Monday. Sales promises aggressive deliveries to close the deal. Wednesday. Production finds out, throws hands up, says "we can't do this". Friday. The CEO arbitrates between the two, decides on gut feeling.

It's called management by emergency. Most Italian manufacturing SMEs live there, and they call it "we're flexible".

The antidote is S&OP, Sales & Operations Planning. It's not a new acronym, it's a 1980 process that still works great. The point is: almost nobody does it well.

What S&OP actually is

S&OP is the structured process (monthly, ideally) where:

1. Sales brings the consolidated demand forecast: open orders, pipeline opportunities, new product launches, seasonality.
2. Operations brings the 3-12 month capacity plan: machines, people, shifts, planned maintenance.
3. Supply chain brings the materials plan: supplier lead times, strategic stocks, supply constraints.
4. Finance brings economic constraints: target working capital, margin, cash flow.
5. Leadership brings strategic objectives: service level, coverage, product mix.

Together, once a month, they decide what to do over the next 3-12 months: capacity to add, stocks to build, orders to accept.

It's not an operational meeting. You don't talk about tomorrow. You talk about the quarter.

Why Italian SMEs don't do it

Five reasons I see every time:

1. "We don't have time to plan, we have to produce". Reply: the time you spend firefighting today, you'll invest in S&OP tomorrow, and it will shrink by 40%.
2. "Forecasts are always wrong anyway". True. But a structured wrong forecast is infinitely more useful than no forecast. You measure error, reduce it, and meanwhile work on the range, not the point.
3. "Sales doesn't want constraints". Yet they complain when production misses deliveries. S&OP closes that paradox: sales signs the forecast, ops commits to capacity. Mutual contract, tracked.
4. "We don't have the numbers". You usually do, but scattered. Two weeks of work set up a minimum S&OP dashboard: demand, capacity, inventory.
5. "There's no dedicated person". Real obstacle. Without a demand planner or an S&OP champion, the process doesn't start. Minimum investment: 1 part-time person for SMEs under 200 employees.

What changes when S&OP is implemented well

Not theory — numbers from real projects:

• OTD up 10-15 percentage points in 6-9 months, without touching the factory.
• Safety stocks down 15-20%, decided on real variance, not gut feel.
• Fewer rush jobs: if sales enter production with a new request, it has to pass through the S&OP forecast. Goodbye to the 30% urgents that block the floor.
• Better capital allocation: you invest in new machines when S&OP shows a systematic constraint, not because "sales promised".
• Cross-department transparency: you argue in the S&OP meeting, not on the shop floor at 5pm. Huge difference.

The trap: "façade" S&OP

Typical failure: the monthly meeting happens, but:

• no shared data (everyone comes with their own spreadsheet);
• nothing gets signed;
• production ignores the sales forecast "because it's wrong anyway";
• accuracy is never measured;
• leadership doesn't show up, or shows up once every three.

It's theater, not process. You can spot it fast: after 3 months, if OTD hasn't moved and rush jobs haven't dropped, S&OP is façade.

How you really start

Realistic minimum sequence for a manufacturing SME between 30 and 300 employees:

1. Month 1-2: define scope (lines, families, markets), owners, cadence. Stand up shared data (even just spreadsheet + ERP).
2. Month 3-4: first "real" S&OP meeting. Start with a short horizon (3 months), then extend.
3. Month 5-9: measure everything: forecast accuracy, OTD, inventory, rush jobs. Iterate the meeting.
4. Month 9-12: integrate APS into the process. APS becomes the engine that translates S&OP into weekly production plans.
5. From month 12: S&OP is culture. People complain when it's skipped, not because it exists.

The uncomfortable truth

S&OP isn't an IT project. You don't buy it from a vendor. You build it. It needs CEO commitment, a dedicated person, and the discipline not to skip the meeting.

That's why many Italian SMEs don't do it: it's easier to buy software than change a behavior.

But the day S&OP works, you discover your factory has 20% hidden capacity nobody saw — because it was burned on rush jobs, wrong stocks, and mid-week schedule changes.

And that 20% costs nothing. It's already there.
