Besides, … Value stream maps are often pushed by consultants that need to familiarize themselves with the shop floor of their client. There are multiple ways of doing this but my preferred one is using Stream.concat() and passing the entry sets of all maps as parameters: Stream.concat(visitCounts1.entrySet().stream(), visitCounts2.entrySet().stream()); Then, comes the collecting part. Each value stream is created for each individual product that pass through the flow, and the network becomes the collection of all streams. Review the following examples : 1. While mapping is useful for individual thinking, it is most effective in a group setting. Value stream mapping can be used to improve any process where there are repeatable steps – and especially when there are multiple handoffs. Value stream mapping supports stream analysis by simplifying a complex system into a map. Each value stream is created for each individual product that pass through the flow, and the network becomes the collection of all streams. To calculate the sum of values of a Map
data structure, firstly we create a stream from the values of that Map, then we apply one of the methods we used previously.
