Abstract: An agile enterprise is an organization that rapidly adapts to market and environmental changes in the most
productive and cost-effective ways. To be agile, an enterprise should utilize the key principles of enterprise
architecting enabled by the most recent developments in information and communication technologies and
lean principles and. This paper describes a Lean Enterprise Architecture (LEA) to organize the activities for
the transformation of the enterprise to agility. It is the application of systems architecting methods to design,
develop, produce, construct, integrate, validate, and implement a lean enterprise using information
engineering and systems engineering methods and practices. LEA is a comprehensive framework used to
align an organization's information technology assets, people, operations, and projects with its operational
characteristics. The architecture defines how information and technology support the business operations
and provide benefit for its stakeholders.The architecting process incorporates lean attributes and values as
design requirements in creating the enterprise. The application of the LEA is less resource intensive and
disruptive to the organization than the traditional lean enterprise transformation methods and practices.
Thus, it is essential that the merits of this process are re-marketed (communicated) to the stakeholders to
encourage its acceptance.
1 INTRODUCTION
In order to effect a successful transformation to
agility, an enterprise requires an integrated set of
activities and support documents that execute their
strategic vision, program concepts, transformation
schedule, communications plan, and technology
implementation strategy. To this end, the authors
created the Lean Enterprise Architecture (presented
in Figure 1). LEA is a structure to organize these
activities for the transformation of the enterprise
from a current state to a desired future agile state.
LEA uses a phased approach structured over the life
cycle of the transformation. It portrays the flow of
phases necessary to initiate, communicate, sustain,
and continuously refine an enterprise transformation
based upon Lean principles, information technology
architecture, and systems engineering.
The top of the illustration in Figure 1 represents
the life cycle of the transformation. The bottom
represents the architecture that is used to create the
life cycle. The architecture is comprised of three
phases.
1. The first component is the Transformation
Strategic Planning phase, which specifies the
actions associated with the decision to adopt
the architecture.
2. The second component is the Transformation
Acquisition and Integration phase, in which the
environment and conditions necessary for a
successful change in the enterprise are created.
3. The organization is then prepared for the
launch into detailed planning and
implementation, which is the third phase, the
Transformation Implementation phase, where
the transformation of the enterprise is planned,
executed, and monitored.
Each phase in this architecture creates the conditions
necessary to put into effect the life cycle of the
transformation. The description of each component
of the life cycle is given in Table 1.

2 THE LEAN ENTERPRISE
ARCHITECTURE
The Lean Enterprise Architecture is an architecture
framework for enterprise reengineering to design,
develop, produce, construct, integrate, validate, and
implement a Lean Enterprise using Information
Technology and Systems Engineering methods. The
design process incorporates Lean attributes and
values as design requirements in creating the
enterprise. This approach to transformation is a
systems engineering method for a Lean enterprise
transformation, as opposed to the standard
incremental Lean methodology that uses a “Design-
Build” and the “Cell-by-Cell” paradigm.
3 THE ROLE OF SYSTEMS
ENGINEERING
AND INFORMATION
TECHNOLOGY
LEA is rooted in the foundations of Lean principles,
information technology architectures, and systems
engineering methods. Enterprise Engineering is
defined as the “collection of tools and methods
which one can use to design and continually
maintain an integrated state of the enterprise” (ISO
WD 15704). Based on this definition, “Lean
Enterprise Transformation Engineering” is defined
to be a discipline that uses the tools of systems
engineering and the management practices of Lean
to organize all of the tasks needed to design,
implement, and operate enterprise transformation
change.
Lean Enterprise Transformation Engineering
uses an Architecture Framework to define and
describe enterprise design and implementation
solutions. Architecture Frameworks describe basic
concepts, descriptions and the related models
(views) to provide a standard for enterprise
engineering (IEEE P1471, 1998). There are four
basic Enterprise Engineering frameworks. These
frameworks are rooted in information technology
architectures:
a. Computer-Integrated Manufacturing Open
System Architecture (CIMOSA)
b. Generalized Reference Architecture and
Methodology (GERAM)
c. GRAI Laboratory Model (GRAI/GIM)
d. Purdue Enterprise Reference Architecture
(PERA).

TRANSFORMATION
ENGINEERING AND THE LEA
Figure 2 shows how the Lean Enterprise
Architecture and the concepts of Lean Enterprise
Transformation Engineering work together to ensure
an effective and successful transformation of the
enterprise to agility. The top of the illustration in
Figure 2 represents the life cycle of the
transformation. The bottom of the illustration
represents the three phases of the LEA. Each phase
in the architecture creates the conditions necessary to
put into effect the life cycle of the transformation.
The middle of Figure 2 (shaded region) is the
framework for the Lean Enterprise Transformation
Engineering. This combination of Lean enterprise,
IT, and systems engineering methodologies portrays

the overall flow of the action steps necessary to
initiate, transform, sustain, and continuously refine
an enterprise.
5 CONCLUSIONS
The Lean Enterprise Architecture (LEA) presented
in this paper uses Lean enterprise, Information
Technology architectures, and systems engineering
methodologies to portray the overall flow of the
action steps necessary to initiate, communicate,
sustain, and continuously refine an agile enterprise.
The architecture was developed from an enterprise
perspective, paying particular attention to strategic
issues, internal and external relations with all key
stakeholders, and structural issues that must be
addressed before and during a significant change
initiative. LEA enables the enterprise to respond
quickly to changes in the environment in which the
organization operates. It serves as a ready reference
to assess the impact of the changes on each of the
enterprise architecture components. It also ensures
the components continue to operate smoothly
through the transformation to agility.
