Value stream analysis is conducted typically for one specific product or service family at a time. In order to identify and distinguish families, lean practitioners use what is called a product family analysis matrix (a.k.a. product quantity process matrix (PQPr)). Many times the families can be easily discerned once the matrix is populated, other times, it is more difficult. The application of a dendogram or binary sort, can be helpful in these situations. Value stream analysis and, with it, flow kaizen, is central to any lean transformation and is specific to product or service families.
