Sales & Operations Planning - Best Practices

Sales and Operations Planning Standard System

With Reference Software

Christopher D. Gray

 

The Sales and Operations Planning Standard System describes a simple set of software functions, primarily those in the areas of aggregate sales planning, aggregate supply planning, aggregate inventory or backlog planning, reporting and display of key performance and planning information, rough-cut (capacity and material) planning, and financial planning. It describes the activities that are part of a working sales and operations planning process, as well as an explanation of the assumptions and the experience that led to these functions. 

The software functions described in the S&OP Standard System include those required to support communication and decision-making focused on volume related manufacturing and supply chain issues. 

In addition it describes some of the key interfaces that must exist with other essential company functions. For example, the S&OP Standard System describes the interfaces to resource planning functions like master production scheduling and sales planning, and the interfaces to lean manufacturing functions like takt time calculations.
