What are we doing here?
Recognize this?http://upload.wikimedia.org/wikipedia/commons/f/f5/Kanban_board_example.jpg
Does this sound familiar?• “Create a single piece batch”
• “Create a pull system”
• “A Kanban board helps you visualize the workflow”
• “Limit your Work-in-Progress”
• “Eliminate Waste”
• “Understand your Value Stream”
These are all Lean terms
What concrete examples can you recall to demonstrate
them?
Does your DevOps/Lean/Agile transformation feel like this?

What is Lean?
The core idea is to maximize customer value while minimizing waste. Simply, lean means creating more value for customers with fewer resources.

Those sound good? How?
Step-by-step Transition Formation Process
1. Find a change agent
2. Find a sensei
3. Seize (or create) a crisis to motivate action
4. Map the entire value stream
5. Pick something important and get started removing waste quickly
Lean Thinking, Chapter 11
Let me try…1. I’m the change agent.
2. I read the Netflix and Etsy blogs, and those are awesome things.
3. I know our deployment pipeline is monstrous, so we should fix that fast.
4. Not sure what this means… so, let me go on to step 5.

How do we map the Value Stream?
What is the Value Stream?
Value• How long does it take for you to provide…
• a desktop?
• a server?
• a DNS update?
• storage?
“Value stream mapping is a lean manufacturing technique used to analyze and design the flow of materials and information required to bring a product or service to a consumer. At Toyota, where the technique originated, it is known as ‘material and information flow mapping’. It can be applied to nearly any value chain.”
Every action you perform to deliver a product or service, should be adding value to
your customer. !
The Value Stream is a visualization of this principle.
How do we map the Value Stream?
Multiple Levels• The Process Level helps you identify the exact
inputs and outputs, the tools, time and people required, and a repeatable method for implementing.
• The “Factory” Level helps you identity the in between where Work-in-Progress waits in queues.
• The “Inter-factory” Level were handoffs are even more disjoint.
Process Level
• Focus is on Inputs/Outputs
• Materials/Products and Work Centers

Current State
• Shows the Value Stream, as it is NOW
• Don’t make an effort to improve it until you know how it looks like.

How can we improve this?
Pull it from the Shelf
• Have one process just pull out what it needs.
• The other process just has to make sure that enough is available at any given time.
• (You’re probably already doing this in many places.)

• This is the model of where we want to go.
• Now we can start building a considered plan for how to get there.
