Being agile and responsive while optimizing the business profit is a key deliverable of today’s supply planning & scheduling functions. We can achieve this by the rigorous implementation of a Sales and Operations Executions (S&OE) process, with clearly defined time fences: fluid, firm and frozen horizons. Closely governed and with clearly defined roles & responsibilities to deal with issues and exceptions, it becomes possible to be flexible when needed, whilst delivering supply chain and manufacturing efficiency.
