1. Value Stream Maps Identify Constraints

2. Constraint Anything that restricts or limits the flow of a process Also called a bottleneck 2

3. 3 Constraints Some constraints are based on time

15. Tips Not all process time adds value Required delays should be recorded as process time Use min/max times to show substantial variability 15

16. Process Timeline Summary 16 Helps determine bottlenecks based on time The value added time The non-value added time

17. 17 Constraints Some constraints are based on time Constraints can also be caused by lack of resources

18. 18 Resource Analysis Does each activity in a POD have sufficient resources to meet demand without building up a queue?

19. Data Box Capture information in data boxes under each activity 19

23. Throughput Rate The amount of work that can EXIT a work center in a given period of time 23

26. Value Stream Analysis Summary A value stream timeline can help you identify presumed value added and non-value added time in a process A value stream resource analysis helps determine the bottlenecks in a process by identifying constrained resources. 26
