A Day On Wikipedia

SIPOC is a six sigma tool. The acronym SIPOC stands for Suppliers, inputs, process, outputs, customers. A SIPOC is completed most easily by starting from the right (‘Customers’) and working towards the left.

For example:

<ol>
<li>Suppliers – grocers and vendors</li>
<li>Inputs – ingredients for recipes</li>
<li>Process – cooking at a restaurant kitchen</li>
<li>Outputs – meals served</li>
<li>Customers – diners at a restaurant</li>
</ol>
