The Software Works. The Operation Still Has Gaps.
Manufacturing software is good at handling standard records: orders, inventory, purchasing, invoices, and other core information. But the work around those records is often more specific. A planner moves two jobs because a supplier is late and records it in a file nobody else opens. A customer needs a particular document that isn't part of the normal order flow. Purchasing sends one revision in the morning and another later in the day. Shipping is working from a printed list that was already out of date when it came off the printer. None of this necessarily means the software was a bad choice — it means the business has details the software was never designed to capture neatly. Those details can look harmless because they live in Excel, email, shared folders, paper, or someone's memory. They become expensive when the person who understands the workbook is away, two versions of the truth appear, or a customer is waiting for an answer that requires three calls and a walk across the floor.
