SIPOC Value Chain | Suppliers Inputs Process Outputs Customers
I really do love the SIPOC model.
It's so versatile for industry supplier chain analysis, internal business process analysis, and right down to marketing communications planning.
SIPOC is an acronym for:
Suppliers > Inputs > Process > Outputs > Customer
And think…
Who > What > How > What > Who
SIPOC reflects the value chain from converting one set of 'raw materials' into a product that the customer (stakeholder, end user, consumer) receives.
The 'process' in the middle are the steps necessary to take the inputs (ingredients for the product) and turn them into the final goods.
The process can be represented as a process map or workflow diagram within the SIPOC chart itself.
Here's a few nice examples:
