Agenda
  • What is value stream mapping
  • Why use value stream mapping
  • How to create a value stream map
  • From process maps to value stream maps

3
What is value stream mapping?
  • Visual representation of processes within a
    pathway
  • Allows you to see all the value-add and
    non-value-add (waste) activities
  • Opportunity to remove non-value-add steps and
    eliminate waste through problem solving
  • Move towards a future state

4
Why use value stream mapping?
  • Reduce and eliminate waste to
  • Improve safety and quality
  • Improve turnaround time
  • Increase capacity
  • Reduce staff frustrations

5
How to create a value stream map
  • Keep it high level - use approximately 6-8
    process steps
  • Focus on the high volume work i.e. 80 of the
    work. This is called the Green Stream.
  • Collect true and accurate information by walking
    through the pathway yourself

From Process Maps to Value Stream Maps
  • What does your current process map show?
  • Where do you need to collect more data in order
    to create a current state value stream map?
  • What is your action plan to do this?
  • Aim to create a future state value stream map
    which minimises waste
