MoM aligns planning, execution, quality, and intelligence so factories run to plan, prove compliance, and improve every week with Siemens Opcenter at the core
From Shifting Numbers to Stable Metrics
If you ask ten people to define MoM, you will hear fifteen answers. The simplest way to think about it is this: MoM is the system of work that turns plans into reliable execution, produces trustworthy records, and shows you where to improve next (International Society of Automation, 2018; International Organization for Standardization, 2014). In Siemens language, Opcenter is the MoM suite that brings these pieces together for planning, execution, quality, and insight on one backbone (Siemens Digital Industries Software, n.d.-a; Siemens Digital Industries Software, n.d.-b).
Start with a shared map. ISA-95 gives you a plain structure for roles and interfaces between enterprise planning and plant control so ownership is clear and integrations are boring in the best way (International Society of Automation, 2018). Use it to answer three questions: what decisions live in ERP versus MES, what events flow between them, and what data proves each step happened (MESA International, 2022; National Institute of Standards and Technology, 2019). Opcenter fits that map: APS makes a finite-capacity plan the floor can run, MES coordinates the work and captures the record, and analytics turn raw signals into decisions (Siemens Digital Industries Software, n.d.-a; Siemens Digital Industries Software, n.d.-c).
Agree next on how to measure. ISO 22400 standardizes the vocabulary behind OEE and related KPIs so availability, performance, and quality mean the same thing across shifts and sites (International Organization for Standardization, 2014). When you add a simple loss tree behind those KPIs and connect identifiers that follow GS1 conventions, you can trace losses to the exact order, material, and step that produced them (GS1, 2017). This is how MoM becomes a map of where to spend the next hour, not just a dashboard (World Economic Forum, 2025).
Why Opcenter for MoM. First, planning: Opcenter APS models constraints, setups, and rules so the schedule matches physics rather than hope, with published cases showing dramatic cuts in planning latency and inventory (Siemens Digital Industries Software, n.d.-d). Second, execution: Opcenter Execution orchestrates work, enforces specs, captures results and signatures, and generates eDHR or eBR when needed so QA can release with confidence (Siemens Digital Industries Software, n.d.-e). Third, intelligence: Insights Hub and Opcenter analytics bring historian and MES signals together so teams see queue growth, false calls, or setup drift before a shift is lost (Siemens Digital Industries Software, n.d.-f; Siemens Digital Industries Software, n.d.-a).
Lighthouse sites that standardize data, align roles, and run short improvement loops report double-digit performance gains that persist beyond pilots (World Economic Forum, 2025).
Three pains MoM fixes fast
Ask this → Get that walkthrough
- Ask: “Who decides what at Level 3 and what must be real time.”
Get: a simple ISA-95 RACI and an event contract for release, start, complete, test, and put-away so hand-offs work every time (International Society of Automation, 2018; MESA International, 2022). Screenshot idea: a swimlane diagram with ERP, APS, MES, and equipment lanes; alt text: “Event flow from order release to operation complete with owning system per ISA-95.”
- Ask: “What KPI proves value this month.”
Get: an ISO 22400 OEE baseline plus a top-loss Pareto connected to GS1 identifiers so you can run a two-week PDCA on the biggest loss (International Organization for Standardization, 2014; GS1, 2017). Screenshot idea: OEE and loss board; alt text: “OEE gauge with availability, performance, quality and a Pareto of top five losses.”
- Ask: “What rule makes the schedule fail.”
Get: a targeted APS model update, like sequence-dependent setups or clean room windows, and a publish rhythm that planners trust (Siemens Digital Industries Software, n.d.-d; Siemens Digital Industries Software, n.d.-a). GIF idea: before or after schedule lanes showing fewer changeovers; alt text: “Two Gantt charts highlighting setup reductions after rule change.”
Proof metric
One public example: a manufacturer cut planning time from three days to two hours while improving schedule reliability after implementing Opcenter APS, demonstrating how finite modeling converts effort into predictable flow (Siemens Digital Industries Software, n.d.-d).
