What are the different types of value stream mapping techniques, and how can you choose the right one?

1 Process VSM

Process VSM is the most common and basic type of VSM, which focuses on the physical and operational aspects of the value stream. It shows the main processes, the inputs and outputs, the cycle times, the inventory levels, the quality indicators, and the value-added and non-value-added activities. Process VSM is useful for mapping the current state of the value stream and identifying the sources of waste and inefficiency. It can also help you design the future state of the value stream by applying lean principles and techniques.

2 Information VSM

Information VSM is a type of VSM that emphasizes the flow of information and communication between the processes and the stakeholders. It shows the information sources, the data types, the data formats, the data quality, the data frequency, the data transmission, and the data usage. Information VSM is useful for mapping the information systems and technologies that support the value stream and identifying the gaps and errors in the information flow. It can also help you improve the information quality, reliability, and accessibility by applying lean information management practices.

3 Service VSM

Service VSM is a type of VSM that focuses on the service delivery and customer experience aspects of the value stream. It shows the customer segments, the customer needs, the customer expectations, the customer feedback, the service quality, and the service performance. Service VSM is useful for mapping the service processes and interactions that create value for the customer and identifying the opportunities and challenges in the service delivery. It can also help you enhance the service quality, responsiveness, and satisfaction by applying lean service design methods.

4 Supply Chain VSM

Supply Chain VSM is a type of VSM that covers the entire supply chain network and the relationships between the suppliers, the manufacturers, the distributors, and the customers. It shows the supply chain structure, the supply chain partners, the supply chain processes, the supply chain flows, the supply chain costs, and the supply chain risks. Supply Chain VSM is useful for mapping the upstream and downstream value streams and identifying the dependencies and constraints in the supply chain. It can also help you optimize the supply chain performance, agility, and resilience by applying lean supply chain management strategies.
