While Sales & Operations Planning (S&OP) has long been established as a strategic standard in supply chain management, the concept of Sales & Operations Execution (S&OE) is gaining increasing attention. However, the distinction between these processes – and from traditional methods such as Master Production Scheduling (MPS) – is often anything but clear.
According to an article from 2022 of Patrick Bower, Senior Director of Supply Chain, Actylis, the problem often lies in confusing planning horizons and data granularity. Without a clean separation of processes, companies risk inefficiencies, redundant work, and blind spots in operational execution.
Comparing Planning Horizons and Granularity
Process | Planning Horizon | Data Granularity | Focus |
S&OP | 3–24 months | Aggregated (product groups, regions) | Strategic–tactical |
S&OE | 0–4 weeks | Detailed (items, lines, shifts) | Operational execution of plans |
MPS | 0–12 weeks | Detailed at SKU level | Control of individual SKU production |
S&OE vs. MPS – What’s the Difference?
S&OE and MPS overlap in operational execution – but:
- MPS is a production-centric tool that defines what, when, and how much to produce – typically focused on finished goods.
- S&OE has a broader scope: It incorporates not only production decisions but also delivery delays, logistics priorities, procurement bottlenecks, and customer demand signals. It is more process-driven and cross-functional.
Thus, MPS is part of S&OE – but S&OE encompasses much more than production control. It ensures the real-time execution of the entire tactical plan.
Research Findings and Practical Observations
Studies from Gartner, Chalmers University, and Supply Chain Insights show: Many companies run MPS processes but lack a consciously structured S&OE process. This results in inconsistent responses to disruptions and missing feedback loops to S&OP.
A functioning S&OE requires:
- Clear roles (e.g., S&OE coordinator)
- Weekly meetings focused on deviations
- Early warning systems (e.g., digital twins, analytics)
- Strong linkage to the monthly S&OP process
S&OP is the roadmap, S&OE is the journey through day-to-day operations, and MPS is just one of many tools – important, but not sufficient.
To build resilient and adaptable supply chains, companies must establish S&OE as a structured process of its own – not just a by-product of MPS or an “ad hoc fire brigade.”
In our training programs, we teach how to set up S&OP strategically, integrate it with S&OE, and incorporate MPS – for a resilient, responsive supply chain. You can find suitable courses here:
