Rules:Draw-er faces away from the screen.
No peeking!Draw what your partner describes.
Ask questions!

Kanban Rules(Lean Manufacturing)
1. A later process tells an earlier process when new items are required.
2. The earlier process produces what the later process needs.
3. No items can be made without a Kanban.
4. Defects are not passed on to the next stage.
5. The number of Kanbans is reduced carefully to lower inventories and to reveal
problems.-Mattias Skarin, “Real-World Kanban”, 2015
6. Always attach Kanban to the items.

Team Exercise
https://en.wikipedia.org/wiki/List_of_pizza_varieties_by_country#/media/File:Supreme_pizza.jpg
5 Minutes1. Create a Kanban board for a pizza company that delivers. Must have:
4-6 columnsheadings for each column.
2. Decide what your Kanban cards will represent.
3. Set the rules (if time). E.g.:
criteria to move between columns?how to flag issues?
Showcase
• Demo your Kanban board• What did you include?
exclude?• What will your Kanban cards
represent?
1 Minute
Granularity Matters!
If 1x = 1 order kanban
order details
order #1
all dresse
dlarge
veggieextra large
2 pizzasfor a family
order details
order #2
100 assorted pizzasfor a conference
A few strategies...1. Slice it up!
Normalise the size of incoming work.(e.g.: break up big orders into smaller ones)
2. Redefine!Choose another definition for your Kanbans.
(e.g.: try “1 Kanban = 1 Pizza” instead)
3. Multiple types!Support multiple types of Kanban.
(e.g.: try “1 Red Kanban = big order” as well)
Iterate!
Expect to adjust your Kanban board a lot when you’re starting out
Visualise.Limit.
Improve.
Why on earth would I want to limit WIP and introduce an
artificial bottleneck
into myprocess?!
Exercise2 Minutes
1. How many sandwiches can your team make?
2. What’s stopping you from making more?(1 reason)
Each sandwich has:
any proteinbread butterany veg
2x 1x 1x 1x
use menu & food cards provided
Results!
• How many sandwiches did you make?
• What was your avg throughput? (# sandwiches / minute)
• What key thing stopped you from making more? (1 reason)
2 Minutes
Acknowledge your Limits
• You already have limits!• So do the teams around you• Make them transparent
• Create a common language for improvements!

Improving with Kanban
Agree to pursue incremental, evolutionary change.
This founding principle is essential!
Remember the goal of Lean:
Maximise Customer Value, Minimise Waste.
Improving with Kanban
• Incremental, evolutionary change
• Baby steps
• Be scientific!
• Collaborate to improve
• work together, across teams!
• Create customer feedback loops
• insight on value we think we’re delivering

Use different levels of granularity to spot potentialimprovements or measure progress.
ok, ok… here’s some
improvement ideas• Sort food cards
• Remove unused food cards
• Ask customers to write down their orders
• Calculate order serve time
• Update menu if items come in/out of stock
• Specialise in certain foods
• Include Customer Waiting To Order stage to measure initial wait time if server is busy.
• Hire more Chefs!
• Hire more Servers!
• … etc …

Sharing ideas across methods
• Lots of Kanban teams use daily standups, retrospectives, reviews
• You can size work & break it up to help manage flow in Kanban
• Apply WIP Limits in Scrum to avoid taking on too much
• Redefine “done” in Scrum to achieve continuous delivery
• See: Scrumban

• Portfolio management• Product development• Product support• Recruitment• Personal Kanban• … and more …
