6. Workshop Breakdown
1. Create a shared context with two rounds of “The
Pizza Game”
2. Map a value stream of the production system of which
you were just a part.
3. Critique the map.
4. Design a future state value stream map.
5. Design experiments
6. One final round of “The Pizza Game” implementing
the changes from the future state map.
7. Discuss theory & Implementation
8. Lean Coffee discussion (if there is time)

8. Pizza Game
You’re opening a new pizza
restaurant. I’m your sponsor, and
have supplied you with ovens,
materials and tools. I expect you
to attract and retain customers
with good quality.

9. Hawaiian Pizza
• Pizza Base (cut paper, buckled edge)
• Tomato Puree (painted red)
• 3 pieces of ham (cut pink post-it-snippets)
• 3 pieces of pineapple (cut yellow post-it snippets)
A pizza has to bake for 30s and is burned after 45s.
After the oven is closed, no other pieces can be put in.

Roles Of Each Team
Cruster(2)[Folds and Cuts crusts]
Saucer(2) [Sauces Crusts]
Pineappler(2) [Pineapples Crusts]
Timer(1-4) [Collects Total Lead & Cycle Time]
Chef(1) [Bakes the Pizza]
Customer(1) [Accepts or Rejects Finished
Pizza]

16. 16
Timers
1. Press start when the round begins.
2. Press lap when the cruster begins
working on a raw material.
3. Press lap at every state change (e.g.
moved to Done, moved to next station,
moved to oven, moved out of oven etc.)
4. Press Stop when the customer accepts or
rejects the pizza.
5. If you do multiple timings in a round take
screenshot of your stopwatch when it’s
done.

17. Round 1
Bake Hawaiian Pizza as fast as you can. On
the first day, all pizza is handed out for free
and we expect a lot of customers.
Optional: Measure cycle/lead time of 10th
pizza.
Play until I say “stop”.

18. Debrief
Scoring
• Completed Pizzas: 5 points
• Unused Pizza Base: -2 points
• Every 3 Unused Toppings: -1 point

19. Round 2
Bake as much Hawaiian Pizza as you can.
Once again, all pizza is handed out for
free and we expect a lot of customers.
Measure the cycle time of the 15th pizza
slice.
Play until I say “stop”

20. Wait, What the Hell is Cycle
Time?!

21. Value Stream Mapping
• Starting from delivery of value to customer, write
down on sticky notes each step taken and an estimate
of (or actual) cycle time. Work backwards from
customer delight to demand. Include handoffs and
queues.
• Different silo, different color. (Cruster vs Pie Maker)
• Discuss Value Add, Non Value Add, and Essential Non
Value Add.

22. One Example of A VSM
22

23. Discuss Value
Assign a judgement of value to each item on the map.
23

24. Examples of “VA”
• Customer discovery interview/experiment
• Coding features
• Deploying
24

25. Examples of “NVA”
• Waiting for review committee to approve design
• Negotiating internal contract
• Maintaining manual test plan repository
• Writing throw-away code (inventory)
• Roles and responsibility documentation
• Fixing bugs
• Queues
• Handoffs
• Overproduction (leads to inventory)
25

26. Examples of “ENVA”
• Planning annual budgets
• Paying taxes
• Activities focused on regulatory compliance
• Writing unit tests to drive features development
• Creating prototypes
• Daily Stand-up
26

27. Evolve
Study
• In which steps did we have disagreement about value?
Share
• Hypotheses about ways to reduce lead time.
Align
• Align the overall map with the customer-centric vision
Limit
• Non value add steps
Learn
• What experiments target improvement?

28. Future State Design
As a team study your map and ask yourself the following
question:
“Given what we have learned, how can we improve lead
time?”
Based on this discussion design a few experiments and
add starbursts to the map.

29. Round 3
Bake as much Hawaiian Pizza as you can. Once
again, all pizza is handed out for free and we
expect a lot of customers.
Implement one of the experiments from your
future state map.
Measure the cycle time of the 15th pizza slice.
Play until I say “stop”

30. A Value Stream Is…
@AdamYuret
“A value stream is the sequence of activities required
to design, produce, and deliver a good or service to a
customer, and it includes the dual flows of information
and materials. “ -Karen Martin

Stream Mapping is Not Waste Elimination

35. Value Stream Map Isn’t…
A process map

36. Strategic Level Value Stream Mapping
• Most effective if
executives/decision makers
participate.
• Most powerful way to use VSM to
see the whole system.
• Focused on connectedness across
organization.
36

37. Tactical Level Value Stream Mapping
37
• Leaders at the highest level within the circle of agency.
• Powerful way to visualize the process with process maps .
• Design tactical improvements using the process.
