There are many types of process maps and process mapping techniques. Which one is most appropriate to use? To start, let’s make a list of the various types of process maps.
They all have their purpose and use. Typically the process maps are used in conjunction with each other as a step by step dive into more and more detail as we progress from the high level view to the details. The Value Stream Map is a high level map that is often created after the SIPOC has been created and reviewed. SIPOC is an acronym that stands for Suppliers, Inputs, Process, Outputs, and Customers that generally outline 5 to 6 high level steps in the process from the beginning to the end.
The Value Stream Map answers the questions of just what is it in general that the process does from the beginning to the end to deliver a product or a service to your customers. The map answers the question, “Where in the process do we deliver value to our customers?” The map will also point out where no value is provided to your customers.
The purpose for the Value Stream Map is to identify where you provide value to your customers and where you don’t. The improvement focus then becomes how to accentuate adding value and how to eliminate where no value is added. The map is used to record processing details like volume, cycle time, processing time, and lead time. These details are used to quantify the resources consumed by non-value adding process steps and the negative impact that has on the customer experience.
