What is a SIPOC diagram ?
The SIPOC is a fairly straightforward process map that looks at the process at a relatively high level. The SIPOC is generally used at the start of a lean six sigma project within the Define step of the DMAIC model. The SIPOC is an excellent tool for visualising and communicating the scope of the improvement project.
What does SIPOC stand for ?
SIPOC is an acronym – S standing for supplier, I standing for input, P standing for process, O standing for output and C standing for customer.
Design of the SIPOC Template
Each letter forms the heading for the underlying information. S-supplier and I-Input are on the left side. O-Output and C-customer are on the right hand side. P-Process is the main and the central column.
Arrows are drawn to connect and show the interactions between the elements of the columns and the rows of the DMAIC.
This refers to the sources of the information or material such as people, functions or systems.
This refers to the items that will be transformed in the process such as the materials, procedures or information i.e. these are the x’s of the process.
This is the heart of the SIPOC and forms the main steps of that are need to transform or make the process work.
This reflects the products or services of the process steps i.e. these are the y\’s of the process.
These are the people, functions, end customers that receive the output of the process.
What are the benefits of using a SIPOC analysis ?
The SIPOC provides an understanding of the various process steps and process owners that make up the system for the stakeholders, project sponsors and team members. It clarifies the scope of the lean six sigma project and highlights potential sources of data for inputs [x's] and outputs [y's] that may be collected during the Measure stage of the DMAIC.
