Look the same, right?


Initially I was only seeing in lean what I already knew from 10 years (120 iterations) of agile. Practicing only lean for years under the guidance of two sensei made me realize the fundamental difference between the two approaches.


Lean 101

What is the problem we are trying to solve?


Context #1 : waterfall

Sample of 20 projects

Customers: « We need you! What are you doing? »


Context #2 : agile deployment

Velocity

Customer expectation

« We need you to go faster! »

A few outstanding successes

After the dust settles:

Better, but difficult to measure


Why the difference?

Outstanding

Better


It’s all about people!


Operational success

Different approaches Agile :

BUILDING

Lean :

LEARNING Practices for developing

the right skills to deliver more value with the least waste

Process for building the right product

with the minimum overhead in an unclear environment

⇒Production system ⇒Training system


The lean perspective

What process and tools should we use?

Who needs to learn what to succeed?


Developing skills

1.  Define the goal 2.  Understand the main obstacles 3.  Create an exercise 4.  Practice with frequent feedback

Exercises: Customer satisfaction Quality Lead time

On the job


Fast results Output from two development teams practicing only lean


Lean AND Agile

Waterfall

Unified Process

…

In a nutshell, it’s:


The lean practice

Create a visual environment that clarifies the challenge and reveals problems

React immediatly

Solve problems one by one

Spread the knowledge

For each team:

Obeya

PDCA

Standards & training


Lean exercises

Deliver right first time

Deliver on time every day

Define value Manager =

Teacher +

Solve specific families of problems


Define value

Lean exercise #1

Go & see users:

! What is the problem we want to solve?

! Why is it important?

!  How and when will we check that it is solved ?

« We need to implement features or user stories X and Y »

Define Value

Dentist wants:

•  Nice Mac-like interface

•  Graphics

•  Mouse navigation

Assistant’s problem to be solved:

•  Enter patient information as fast as possible with no errors

" fast, keyboard-based, no bells & whistles interface

Initial business case Results of the go&see

Non-agile context

How do you save 1 hour out of 10 minutes?

How can we call that a simplification?


Deliver Right First Time

At every step in the process:

! What quality problems were found?

! Why did they occur? Why? Why?

!  How can we prevent these problems from happening again?

« We need more resources for testing »

Deliver on time every day

!  Is the project on track today? How do you know?

! What happened? Why? Why? Why?

! What are you planning to do?

« It took longer than expected, we should have planned better »

Lean exercise #3

From:

To:


Getting past « wrong estimates »

Control Lead Time

To: From:

« The estimates were wrong »

« WHY ? »

Agile context


On time every day

Control Lead Time

« Everything is okay » Daily goals

Fine-grained milestones with problems made visible

Agile ! Lean


Agile first ?

Agile

Lean

What is the problem you are trying to solve?


Lean first!

Define the challenge Engage the teams Visualize the causes What practices (agile or not) are really needed? Let the teams own the choice to start with agile or not


It’s all about them


It starts with you

Let’s go beyond the taylorist habit of imposing processes on people:

1.  Clarify the challenge

2.  Engage the team

3.  Teach them how to solve on their own the problems they face, without giving solutions


Thanks!
