KIE Factory Stories: Why Did the Factory Make 10,000 Extra Parts That Nobody Ordered?

“Where did these 10,000 components come from?”

The Finance Manager was staring at the inventory report.

The Production Manager checked the schedule.

Every production order had been completed correctly.

The machines had performed well.

The operators had met their targets.

So why was the factory holding so many extra components?

The Industrial Engineer investigated.

He discovered that the production planning system was using outdated demand information.

Sales had reduced the customer forecast two months earlier.

But the production team was still following the old forecast.

There was another issue.

The factory was producing in large batches to reduce machine changeover time.

Even when demand dropped, production continued until the entire batch was completed.

The result?

More inventory, more storage requirements and more cash tied up in products that customers did not need yet.

The team improved forecast communication, reviewed production schedules more frequently and introduced better batch-size planning.

Inventory gradually came under control.

This is the importance of Sales and Operations Planning (S&OP).

Production, Sales, Purchasing and Finance must work from the same business picture.

A factory cannot plan effectively when every department is working with different numbers.

Producing according to an outdated forecast is not productivity.

The best production plan starts with the right information.
