In a value stream map, the information flow is commonly placed at the top, material flow at the middle, and the VSM timeline are placed at the bottom of the map.
This is an example of a current state value stream map for a typical manufacturing process.
Value stream mapping can also be applied in service-related industries such as healthcare, hospitality and logistics. This example illustrates a value stream map for an equipment installation process.
This is an example of a current state value stream map that was created for a specific product family in a manufacturing facility.
Final yield (FY) is widely used yield metric that is easy to calculate. This is an example of a 3-step process map which has a final yield equals that is equal to 90%.
This is a process that has 3 steps performing at a 0.94, 0.91 and 0.92 respectively. If 100 units entered the process and only 89 were good units, final yield would be 89%, and rolled throughput yield would be: 0.94 x 0.91 x 0.92 = 78.7%.
In this can-making process example, the probability of manufacturing a can that meets all performance standards would be 90.28% (i.e. RTY = 90.28%).
This is an example of a SIPOC map for an idea generation and implementation process.
This is an example of a SIPOC map for a car purchasing process at a car dealership.
This is an example of a SIPOC map for conducting job interviews during a recruitment process in a company.
A SIPOC map can be created quickly by drawing a table of five columns. These five steps describe how to create a SIPOC map with your team.
These questions can be useful to complete the SIPOC analysis exercise with your team.
There are many classifications of waste. One of the most basic and widely used models across many industries is the Eight Wastes.
Process maps are used to map existing processes (what the process really is), as well as to map the future state of how things should be after implementing process improvement (what the process should be).
Just like real maps, process maps can be created in different levels (vertical expansion). Also, the process itself can be as simple or as complex as required (horizontal expansion).
