The document outlines a three-step approach for process improvement. First, it suggests analyzing the value stream with a flow diagram to differentiate between value-added and non-value-added steps. Second, it emphasizes identifying sources of waste and variation, and third, it advises identifying process drivers and validating them with a specific tool.

1. 1.Analyze the value stream by using a flow diagram to map the
value added and non-valued steps in the process.
2.Analyze sources of waste and variation through the use of a
tool recommended in Theme 3.
3.Identify the process drivers and validate them through the use
of a tool recommended in Theme 4.
