§  Why CMMI?
5
The Business View of IT
Origins of the Problem
§  Complexity: IT projects are viewed by the business as extremely complex
and hard to understand
§  Misdirection: IT often fails to grasp the intentions of the business when
building applications
§  Project Failure: projects often run over-budget, late, and fail to deliver the
expected benefits
§  Cost Focus: IT is often viewed as a cost center instead of a business
enabler
§  Speed: the reaction time of IT to changing business environments is
perceived as too slow
6
The IT View of Business
Origins of the Problem
§  Conflicting Priorities: the business is often unclear on what the priorities are
for the IT organization
§  Lack of Inclusion: IT is often brought into projects late and are not offered
the chance for collaboration
§  Multitasking: too many projects are assigned to IT at once
§  Gold-plating: excessive automation instead of doing the simplest thing that
works adds to complexity
§  Poor quality control: defect acceptance has become the norm and the
business does not want to invest in a quality product
7
The Real Problem?
8
Attacking the Problem
The Agile Movement Begins
Agile Grassroots Movement:
§  Began in 2004
§  Different coaches lead to localized
Agile processes
§  Lack of communication between
Agile teams
Agile
§  One project at a time (Pilot)
§  Each saw success, but had limited
impact on the overall enterprise
9
Agile at Nationwide
Coordination and Collaboration Begins
§  Began in summer of 2008
§  Harvested Agile best practices
§  Nationwide s leading Agile activists
together for first time
§  Focused on Scrum and XP practices

Now that we have the pieces, how
do we scale them?
12
How Much Scale?
§  Hundreds of millions of dollars spent on building software
§  Thousands of IT associates
§  Development platforms include
distributed, mainframe, mobile,
and client-server
IT is the lifeblood of our industry –
our products are data and
information flows
13
The Application Development Center
Enterprise Agile
§  In 2009, Nationwide forms the Application
Development Center
The New Problem…
§  Repeating localized success
§  Only a handful of successful Agile teams
Agile
§  Nationwide s 21 Agile Tea Leaves were
philosophy not process
§  A Framework was needed to scale Agile at
Nationwide
14
A Framework for Agile… Lean
To Summarize: no reuse, no standards, inability to replicate
agile successes across the enterprise…
How to tackle these
problems?

The ADC
transformation focused
on creating a
sustainable system,
not implementing a
series of tools or
techniques. Culture
shifts were required in
staff and management.

Lean Development System
The Engine of a Lean IT Transformation
The Lean Development System governs how the actual work
is executed, improved, and monitored in the overall system.
The Development System:
§  Creates an efficient process sequence with the lowest
possible waste
§ 
Standardizes routine work items to allow our knowledge
workers the freedom to concentrate on value-added
activities
§  Empowers team members to continuously improve upon the
standards and improve the entire ADC with their ideas
17
Standardized Work
Basis for Continuous Improvement
Standardization is not just for manufacturing environments.
Standardized Work applies as much to Information Technology as
it does to manufacturing and other industries.
Why is standardization in the ADC important?
Maintains a consistent level of quality
Stabilizes the working condition
Allows for the judgment of normal from abnormal conditions

Waste Elimination
Increased Productivity
Improved Morale
Foundation for Improvement Activities
Kaizen, Continuous Improvement, and A3s
Relentless Pursuit of Perfection
/kai ‫ י‬zen/ - continuous incremental improvement
Kaizen is a philosophy of continuous improvement that pervades
throughout all areas and aspects of the organization. It is embedded in
our culture and becomes a part of who we are in the ADC.
Nationwide ADC Continuous Improvement
§ Applies to both formal kaizen events and kaizen eyes – everyday
continuous improvement to root out waste
§ Is driven by practitioners
§ Provides a governance mechanism for pushing changes into our
processes
§ Utilizes A3s to ensure PDCA thinking as well as other lean tools
such as 5 Whys, Fishbone, etc.
Lean Management System
A Necessary Pillar for the Lean House
We teach our associates how to be lean workers, but
forget to teach our managers how to be lean leaders.
Lean Processes Need Lean Management!
Without the Lean
Management System, the
gains of implementing a
Lean Development System
cannot be supported and
maintained.

Leader Standardized Work
Traditional management places
emphasis on getting results at
the expense of process and
system thinking.
This creates short-term gains,
but frequently causes long-term
pain.
Leader standardized work ensures leaders use systems thinking
and focus on training others, managing flow, and eliminating waste.
Standardized work is the tool used to ensure this focus happens
automatically every day in a lean organization.

Leader Standardized Work in the ADC
Standardized work is specific and focused on value adding
activities. Different levels in the organization have varying
amounts of standardized work versus discretionary work.
