6. To Communicate with all upstream and downstream Customers

Information is useful, only if it is available, where it is required and when it is required.
The role of communication to make it available where required, when required and in a form that it is easily understood is essential.
For example, an order received from a customer needs to be communicated to Sales-Despatch, MPC, PPC, Production, Stores, Purchase, Quality and maybe some more contributing Departments. Similarly an order canceled would also require to be communicated.
