My Other Interest
Learning
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) 6
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.
Pizza Game
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
Timers1. 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.
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”.
Debrief
Scoring
• Completed Pizzas: 5 points
• Unused Pizza Base: -2 points
• Every 3 Unused Toppings: -1 point
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”
Wait, What the Hell is Cycle Time?!

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.
One Example of A VSM
22
Discuss ValueAssign a judgement of value to each item on the map.
23
Examples of “VA”
• Customer discovery interview/experiment
• Coding features
• Deploying
24
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
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
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?
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.
28
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”
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
The Primary Purpose of Lean & Value Stream Mapping is Not Waste Elimination

Value Stream Map Isn’t…A process map
35
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.
37
Tactical Level Value Stream Mapping
• 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.
