MES Requirements for Manufacturing Operations

4M CONDITION CHECKLIST FOR MANUFACTURING PROCESS 4M Condition Table specifically tailored for the manufacturing sector, focusing on production process control, machine reliability, material conformity, and operator discipline. 1. Man (Operator) The operator is at the heart of any manufacturing process. Ensuring their readiness and discipline is critical. Operators must be trained and certified for the specific machines or tasks they handle. They should have clear awareness of safety procedures, quality standards, and work instructions. Physical and mental fitness must be monitored to avoid fatigue-related errors. Proper use of PPE (Personal Protective Equipment) such as gloves, helmets, and goggles is mandatory. Adherence to 5S and standard operating procedures (SOPs) ensures a clean and organized work area. 2. Machine (Equipment) The condition of machines directly affects production performance and product quality. Machines should be well-maintained, with preventive maintenance done as per schedule. Tools, jigs, and fixtures must be properly set and in good working condition. Safety systems like guards and emergency stops must be functional at all times. Machines should be free from abnormal noise, vibration, or leakage, indicating stable health. Critical spares must be available to avoid production delays due to breakdowns. 3. Material (Raw and In-process) Material quality and handling significantly influence the final product outcome. All materials must be received as per BOM (Bill of Materials) specifications and verified through incoming inspection. Proper labeling and traceability (batch number, lot number) must be maintained. Storage conditions should be appropriate to avoid damage, contamination, or rust. FIFO (First In, First Out) must be followed to manage shelf life and batch usage. Material must be available in the right quantity at the right time to prevent stoppages. 4. Method (Process) A standardized and controlled method ensures consistency and reduces variation. SOPs or work instructions must be available at the workplace and strictly followed. All process parameters (like temperature, pressure, torque) should be defined and monitored. In-process quality checks should be performed and recorded regularly. Cycle time and takt time must be maintained as per planning. Any changes in methods or processes must be documented through change control procedures.

How to define your plant model before you select a MES. In our last post we covered why a mismatch between a plant's operational model and a selected MES product's built-in model is expensive, sometimes to the tune of $2-3M expensive. This post provides a conceptual framework to define the plant model before vendor demos. Borrow from ISA-95. ISA-95 is an international standard for modeling manufacturing operations. We find it to be a great standard to, among other things, use a common language to define how operations in the plant works. For the purposes of this post we'll borrow its structure. For your process to define the plant model and requirements for the needed MES, start with these five definitions: 1. Equipment hierarchy (Part 1) Draw your physical structure top-down: Enterprise → Site → Area → Work Center → Work Cell. Most engineers can sketch this in an hour from memory. 2. Activities in your 4 operational domains (Parts 3 & 4) For each domain, list what work actually happens on your floor: • Production: what operations transform material into product? • Maintenance: what planned and unplanned work happens on equipment? • Quality: where are inspection, hold, and disposition decision points? • Inventory: where does material move, get consumed, or get stored? Get out in the plant for this work...this isn't desk work. 3. Resources mapped to activities (Parts 2 & 3) For each activity above, answer three questions: What equipment executes it? Who performs or oversees it? What materials are consumed or produced? 4. Product and process model (Parts 2 & 3) Pull existing BOMs and routings from ERP — they're already partially defined. Gap-fill what ERP doesn't capture: sequence constraints, work center rules, rework paths. 5. Operational events (Parts 3 & 4) Ask operators: "what causes you to stop, hold, or change what you're doing?" Those answers are your events — work order triggers, quality holds, downtime starts. With some familiarity of ISA-95 a good engineer can complete a first draft of the first five in a week's time on the floor. Focus should be clarity and simplicity, not complexity. If time allows, add: • Information flows (Parts 3 & 4) — what data is produced or consumed at each activity • Performance expectations — rate, yield, and quality thresholds at each work center Now use it. Now take that model into MES vendor evaluations. Map it against each MES product's data model. Find the gaps before you sign a contract — not 6 months into implementation.

My recent post on hybrid project methodology triggered good discussion about the roles IT and OT should play. Here’s what we’ve seen work—and what doesn’t. MES projects create more friction than any other industrial technology deployment because it’s the only system that straddles both worlds—IT and OT. IT’s World: Infrastructure, security, scalability, enterprise integrations (ERP, PLM, quality systems), data governance, vendor management, and budget accountability. A poorly architected MES creates security vulnerabilities, integration nightmares, and compounding technical debt. OT’s World: Shop floor operations, equipment integration, real-time production decisions, operator usability, and manufacturing process expertise. An MES that doesn’t work for operations becomes expensive shelfware, no matter how well it integrates with ERP. The Problem: When IT leads alone → You get a system that checks enterprise boxes but doesn’t work on the floor When OT leads alone → You get a system that works locally but creates enterprise integration and security problems Why MES is Different: Every other industrial technology sits clearly on one side: SCADA/HMI and PLCs are OT domain. ERP and identity management are IT domain. But MES collects real-time data from PLCs while posting to ERP. It manages shop floor workflows while enforcing enterprise compliance. It makes split-second production decisions while maintaining audit trails for regulators. It needs both perspectives from day one. What we’ve seen work: - IT defining architecture, security, and integration standards - OT defining workflows, usability, and operational requirements - Both collaborating on vendor selection and implementation - Clear accountability: IT owns infrastructure and enterprise integration, OT owns operational outcomes The worst deployments? One side decides, the other lives with it. The Challenge: In many organizations, IT reports to Finance, driving consolidation, standardization, and cost reduction. But manufacturing is about managing variability, responding to real-time conditions, and continuous improvement. MES sits at the intersection. It fails when we pretend it belongs to just one world. Less than 10% of manufacturers globally have achieved true MES maturity. The gap isn’t technology capability—it’s that IT purchased an off-the-shelf “configurable” MES without understanding operational requirements, or OT built something that can’t scale or integrate. When IT alone selects MES, they often buy a solution that reduces operational efficiency rather than enhancing it. MES success requires both IT rigor and OT expertise working together from requirements through deployment.

Manufacturing Planning and Control (MPC) System MPC effectively plans and controls the manufacturing process, which encumbers everyone within the process such as materials, machines, people, and suppliers. Let’s look at each stage in a little more detail: 1. Strategic Business Plan (SBP) The SBP is a statement of strategic and forward-looking company goals and objectives and focuses on profitability, productivity, customer lead times, and other key areas for the business. The plan gives general direction about how the company hopes to achieve its objectives. The level of detail in the strategic plan is not high as it contains general market and production requirements and not sales of individual items. A well laid out SBP drives everything in the business. It is also an input to the S&OP process. 2. Sales and Operations Plan (S&OP) S&OP is a cross-functional, coordinated plan that involves sales, marketing, product development, operations, and senior management. Actual demand is repeatedly compared with the sales plan. Market potential is assessed and future demand is forecasted. During this process, decisions related to trade-offs between volume and product mix are made so that demand and supply are in balance. S&OP feeds into the MPS. 3. Master Production Schedule (MPS) MPS is a production plan at an individual end product level, by time period. The planning horizon depends on the production and purchasing lead times, but is generally smaller units of time. MPS delivers a master schedule with an anticipated build schedule by specific product configurations, quantities and dates. MPS needs validity through the Rough-Cut Capacity Planning (RCCP) and the output of MPS is the input to the MRP stage. 4. Material Requirements Planning (MRP) MRP uses bill of materials data, inventory data, and MPS to calculate requirements for materials. It makes recommendations to release replenishment orders for material. It establishes when the components and parts are needed, to make each end product. The planning horizon depends on the leads times for manufacturing and purchasing. MRP, being at the detailed level, also considers finite capacity through Capacity Requirements Planning (CRP). And the output of MRP goes into the PAC stage. 5. Purchasing/Production Activity Control (PAC) Purchasing is responsible for establishing and controlling the flow of raw materials into the factory. The level of detail is high since it involved individual components, work centers, and orders as needed daily. A Manufacturing Execution System (MES) is a subset of PAC capabilities. The output of a well-managed PAC is a manufactured product with full visibility and high quality across the supply chain. At each level of an MPC system, it’s important to look at performance measures for more-informed decisions, proactive course correction, and plan modification. Source: https://lnkd.in/dH_BZyKN

Your #ERP and #MES should be synchronised for relevant master data: - Materials - Production Orders - BOMs - Routings - ...and much more depending on the capability of the MES. Otherwise you need to maintain data in multiple places - not a recipe for success! But please don't think this means your existing ERP master data is sufficient... MES is a more detailed application for factory data.... that's why you are investing, to get a more granular and real time view of the factory.... So guess what....the master data in ERP needs to be at the level to support MES. The truth is, most solo ERP implementations have enough to worry about, so often the level of detail in the routing is limited to what is required for cost purposes - that's no criticism, it's just fact, it's what was needed at the time, based on the information available. So, a part of any MES project is actually getting the ERP master data correct, and this often means improving the master data around materials, boms, and most commonly - routings. If you want connected applications, with common shared master data, then it's kind of obvious, right? The system of record for each piece of master data needs sufficient level of detail for all the applications that rely on that data - not just MES, but WMS, EAM, and other applications in the landscape. If you are implementing a new ERP, or upgrading ERP, and you are looking ahead to MES as part of that project, or in future - then you need to think about this ahead of time, otherwise you could end up doing the work twice. Where are the common areas you see confusion around master data? Interested to hear any comments below....

Teams usually think a BOM is “just a list of parts.” In reality, it’s one of the most complex, high-impact systems in manufacturing - and this map shows why. BOMs don’t fail because of missing parts. They fail because organizations don’t understand the processes around the BOM, from revisions to cross-system sync to approvals and real-world feedback loops. Master the operations, and you eliminate most production errors before they ever reach the shop floor. Here’s a quick breakdown of what it covers: 1. Create - How BOMs are initially formed From CAD structures to configurable or plant-specific BOMs. This is where the authoritative product structure begins, and where early mistakes ripple downstream. 2. Compare - How differences and mismatches are identified EBOM vs MBOM, released vs working BOM, supplier vs internal builds. Comparisons catch the mismatches that quietly cause rework, delays, and scrap. 3. Sync - How BOM data stays aligned across systems CAD → PLM → ERP → MES. Attributes, quantities, and revisions must move cleanly across tools, or execution falls apart. 4. Validate - Ensuring BOM quality before it ever reaches production Validating existence, units, lifecycle states, effectivity, and mandatory attributes prevents costly shop-floor surprises. 5. Transform - How BOMs adapt for different needs EBOM → MBOM, plant-specific sequences, service BOMs. Design intent must be translated into production reality. 6. Approve - How BOMs gain authority Engineering, manufacturing, quality, and change-board sign-offs ensure the structure is reliable and compliant. 7. Release - Making the BOM executable Once released to ERP, the BOM drives procurement, planning, and production orders. No turning back, precision matters. 8. Change - How BOMs evolve over time ECRs, ECOs, impact analysis, structural revisions. Change control prevents chaos as products mature. 9. Track & Audit - How BOM history is preserved Revision tracking, compliance audits, and deviation analysis ensure traceability and regulatory alignment. 10. Feedback - Closing the loop from execution to engineering Shop-floor issues, supplier deviations, and quality feedback help improve future releases - the most overlooked step in most organizations. A BOM isn’t a document, it’s a living system. Companies that manage the full lifecycle avoid delays, scrap, rework, and multi-million-dollar quality failures. Those who don’t… keep wondering why their manufacturing never runs smoothly.

SUPPLY CHAIN & PLANNING TOOLS ⚒️ Section-A: Material Requirements Planning (MRP) Basics MRP is a key tool used in manufacturing and production management to plan and track the Demand Management & Production Requirements. 1. Bill of Materials (BOM): A practitioner needs to have a comprehensive and up-to-date bill of materials for the product being manufactured. The BOM lists all the components and raw materials required for production, along with their quantities and relationships. 2. Master Production Schedule (MPS): The MPS is a detailed plan that outlines the production requirements for each finished product. It includes information such as the quantity to be produced and the timing of production. 3. Inventory Control: A practitioner should have knowledge of inventory management techniques, such as ABC analysis, reorder point calculation, and safety stock determination. This helps in maintaining optimal inventory levels and avoiding stockouts or excess inventory. 4. Lead Time: Understanding the lead time for each material is crucial. Lead time refers to the time taken for an ordered item to arrive or be produced. Accurate lead time information helps in effectively planning production schedules and material order timings. 5. Demand Forecasting: Accurate demand forecasting plays a vital role in MRP. By analyzing historical data, market trends, and customer demand patterns, a practitioner can estimate future material requirements more accurately. 6. MRP Software: Familiarity with MRP software is essential for practitioners. It simplifies the calculation of material requirements, generates automated purchase and production orders, and provides real-time visibility into the production process. 7. Capacity Planning: Understanding the production capacity of the facility and its constraints is crucial for MRP. Practitioners need to consider the available capacity while planning material requirements to avoid production bottlenecks and ensure efficient resource utilization. 8. Communication and Collaboration: Effective communication and collaboration with various stakeholders, such as suppliers, production teams, and other departments, are important. This ensures that accurate and timely information is shared, and everyone is aligned towards achieving production goals. Overall, a practitioner should have a deep understanding of the interconnectedness of production, inventory, and demand to effectively implement material requirements planning. By considering these key aspects, practitioners can optimize their material planning process, reduce costs, and improve overall operational efficiency. #materialmanagement #supplychain #strategy

SAP PP is NOT just “creating a production order”. And if you think it is, you’re probably missing 60% of what really happens behind the scenes 👀 Let me break down the REAL end-to-end SAP PP process, with MM, EWM, QM and CO fully integrated 👇 ⸻ 🔹 1️⃣ Demand & Planning (PP Core) Everything starts with: • Sales Orders or Forecasts (PIRs) • Strategy Groups (MTS / MTO) • BOMs, Routings, Work Centers ➡️ MRP runs and creates: • Planned Orders • Purchase Requisitions • Capacity Requirements 👉 MM already kicks in here (PRs) 👉 CO starts estimating planned costs ⸻ 🔹 2️⃣ Production Order Creation Planned Order ➜ Production Order (CO01) SAP explodes: • BOM → component reservations (MM) • Routing → operations & capacities • Costing → planned costs (CO) • Inspection type → QM integration At this stage, the production order becomes the single backbone object. ⸻ 🔹 3️⃣ Material Staging (MM + EWM) This is where many projects fail. Components are staged: • Via PSA • Via Kanban • Via manual or automatic picking • With or without Handling Units 👉 EWM creates warehouse tasks 👉 Stock category matters (Unrestricted / QI / Blocked) PP does NOT move stock. EWM does. ⸻ 🔹 4️⃣ Production Execution (Shop Floor / MES) During execution: • Confirmations are posted • Yield, scrap, rework are reported • Components are consumed (261) Backflush or manual consumption? 👉 MM updates inventory 👉 CO posts actual costs 👉 EWM consumes from PSA 👉 QM may trigger in-process inspections ⸻ 🔹 5️⃣ Quality Management (QM) Inspection lots can be created: • At order release • During operations • At Goods Receipt Results recording ➜ Usage Decision Accept? Scrap? Rework? Quality directly impacts: • Stock status • Production flow • Costs ⸻ 🔹 6️⃣ Goods Receipt (101) Finished product is received: • Stock increases (MM / EWM) • Accounting document is posted • Final inspection may be triggered (QM) 👉 CO credits the production order 👉 Variances start to appear ⸻ 🔹 7️⃣ Costing & Settlement (CO) Final step: • Planned vs Actual costs • Variance calculation • Settlement to material / cost center / profit center No clean PP process ❌ without clean CO integration. ⸻ 🔁 In one line: Demand → MRP → Production Order → Staging → Execution → QM → Goods Receipt → Settlement ⸻ If you work with SAP PP, S/4HANA, EWM, MES or manufacturing, 📌 save this post 🔁 share it with your team I’ll publish next: • PP vs EWM responsibilities (who does what) • Common PP-EWM integration mistakes • How MES really fits into this flow Follow for real SAP manufacturing content �� #SAP #S4HANA #SAPPP #Manufacturing #EWM #QM #CO #MES #SupplyChain #ERP
