  1. 1. Article Coherency Management: Using Enterprise Architecture for Alignment, Agility, and Assurance By Gary Doucet, John Gøtze, Pallab Saha, Scott Bernard ABSTRACT This paper represents a significant point of evolution in thought and practice about the design and management of complex enterprises that often exist in highly dynamic, sometimes chaotic operating environments. The paper asserts that Coherency Management is the primary outcome goal of Enterprise Architecture (EA); that the architecture of enterprises should be formalized and promote coherency; and the best way to do this is to adopt EA as the ongoing, overarching method for abstracting, analyzing, designing, and re-engineering new and existing enterprises - regardless of the market, industry, or government sector that the enterprise belongs to. EA is about more than technology as it now has strategic and business dimensions - all of which must align to create agility and assurance in promoting transformation and delivering value. The paper discusses three modes of EA, namely Foundation Architecture, Extended Architecture and Embedded Architecture, that represent progression in thought and practice, with emphasis that the modes are independent but not necessarily mutually exclusive. The paper also discusses how collectively these influence enterprise coherency. The paper concludes by elaborating the ways and approaches to assess organizational coherence. KEYWORDS alignment, agility, assurance, change management, coherence, enterprise architecture, governance, organization design, risk management, strategy, transformation INTRODUCTION This paper represents a significant point of We see Coherency Management as the most evolution in thought and practice about the influential and important outcome of EA. This design and management of complex enterprises approach to EA is about more than technology that often exist in highly dynamic, sometimes as it now has strategic and business chaotic operating environments. The concept of dimensions, all of which must align to create Coherency Management is about using agility and assurance in promoting Enterprise Architecture (EA) to advance transformation and delivering value. EA is still a alignment, agility, and assurance in large, young and still evolving management discipline complex organizations. The essence of this that now includes all dimensions of an enterprise concept is that the architecture of enterprises and therefore is uniquely able to serve as the should be formalized and promote “meta” approach for designing and/or re- coherency, and the best way to do this is to designing enterprises to successfully compete in adopt EA as the ongoing, overarching method highly dynamic public and private sector for abstracting, analyzing, designing, and re- environments.

EA has the methodology. Figure 1 below shows these potential to align strategy, business, and relationships. technology elements across the entire enterprise, and can provide the context and standards for implementing a number of industry and government best practices including strategic planning, capital planning, service- oriented architecture, information technology infrastructure libraries, knowledge management, program management, security controls, internal controls, quality management and human capital management (Bernard, 2005; Saha, 2007). We use coherence as a term that speaks to a logical, orderly, and consistent relation of parts to the whole. The paper uses this term as a central theme, which is appropriate and necessary in presenting ideas about how to design and operate complex enterprises that must continually adapt to changes in mission Figure 1.

Enterprise Architecture provides significant business benefits to many types of enterprises, We see that today EA is highly isolated, many of which demonstrate a high degree of detached, and disconnected from the rest of the capability and discipline in areas such enterprise (with the exception of IT department). as strategic planning, policy design and The primary reason for the disconnectedness is execution, technology planning and that most (if not all) EA programs are still driven standardization, knowledge and data by the CIO / IT Department (Gøtze & management, enterprise integration, program Christiansen, 2007).

Many of these best factor in characterizing the EA program.

Internally within an enterprise, leveraging on other management practices not only ensures To illustrate the three modes, let us first consider continuity and sustainability in the EA program, an enterprise that is new to EA. This scenario is but also tighter vertical and horizontal alignment. depicted in Figure 2 below. Figure 2.
