Resource Center

A Manufacturing Execution System is the software that sits between your ERP and your shop floor. While ERP manages the plan (what to build, when, and for whom) an MES manages the execution: dispatching work orders to operators, capturing labor and machine time, enforcing quality checks, tracking materials lot by lot, and recording exactly what was built and how. The international standard that defines MES functionality is ISA-95 (also known as the MESA model). It breaks manufacturing execution into several core domains: Production execution: Work order dispatch, electronic work instructions, operator clock-on/off Data collection: Real-time machine and operator data, barcode/RFID scan, manual entry Quality management: In-process inspections, non-conformance, CAPA tracking Traceability & genealogy: Lot/serial tracking, as-built records, recall readiness Performance analysis: OEE, downtime reasons, scrap rates, throughput Labor & resource management: Skills, certifications, labor capture against orders If you're managing any of these today, even informally, you're doing MES work. The question is whether your tools are keeping up with your operation. Isn't that what work orders in NetSuite are for? Sort of. NetSuite's native work order functionality is excellent for planning and financial purposes. It creates demand, allocates inventory, and closes out costs against the job. But it wasn't built for what happens between the moment a work order opens and the moment it closes. On the shop floor, a work order involves multiple operation steps, multiple operators across multiple shifts, real-time material issues, setup time, run time, scrap, rework, and quality holds. NetSuite records the result. An MES manages the process. NetSuite tells you a work order is done. SuiteX MES tells you how it got done… step by step, operator by operator, part by part. Key capabilities include: Work order creation, synced in real time Step-by-step operation dispatch, full routing with sequencing Operator-level labor capture with live start/stop at each step Built-in, step-level electronic work instructions Real-time completion tracking by operation and quanitity Automated OEE & downtime tracking with reason codes Lot/serial traceability  What does an MES actually look like in practice? In SuiteX MES, an operator on the floor starts their shift and opens a work order dashboard, configured to show exactly the jobs assigned to their workcenter, segmented by status and due today. They tap into a job and see their operation steps in sequence. Each MES card shows the routing step, the expected setup time and run time, and the work instructions for that operation, including drawings, SOPs, reference documents, all accessible without leaving the screen. The operator hits start, works the job, and hits complete. Time is captured automatically and posted against the work order in NetSuite without end-of-day catch-ups or manual re-entry. As they step through operations, the system sequences them to the next step automatically. If a step is partially complete, it flags it. When the final operation closes, a full summary displays the total units completed at each step, total run and setup time, and any issues logged. The work order is closed in NetSuite with a single tap. Signs your operation is ready for an MES You don't need to be running 24/7 continuous production to benefit from an MES. You need it when your current approach to managing the shop floor is creating friction, errors, or blind spots that cost you. Here are the most common signs: Paper travelers or whiteboards are your primary method of tracking work order status Labor time is entered after the shift, from memory, or not at all You find out about quality issues after parts have already moved downstream A customer asks for lot traceability on a shipped order and it takes hours to reconstruct You're estimating OEE or scrap rates rather than measuring them Operators ask supervisors which job to run next rather than seeing a live queue What about manufacturers who aren't quite there yet? MES doesn't require a mature operation. In fact, implementing MES often is how an operation matures. If you're currently on paper or spreadsheets, going directly to a native-ERP MES like SuiteX is often faster and cheaper than first building out manual processes and then replacing them later. The right question is whether the cost of your current approach, in labor re-entry, quality escapes, lack of visibility, and integration overhead, is higher than the cost of fixing it. For most discrete manufacturers on NetSuite, it is. An MES is the operating layer you are missing An MES connects your ERP plan to the reality of your shop floor. If you're running on NetSuite, SuiteX MES is the only solution that lives inside your existing system rather than alongside it. Schedule a demo to see SuiteX MES in action and speak with our team.
