Welcome to the Papers section of EAPJ. This section features papers produced by students and practitioners that allow a case-study style approach to the treatment of problems faced by Enterprise Architects worldwide. Have a look through the papers listed below. I’m sure you you’ll find something insightful and useful.
Architecture for the US Army Human Resources Enterprise
By Seth Dorris
The Department of the Army (DA) is an agency of the Federal Government that has an established enterprise architecture program per the Clinger-Cohen act of 1996. However, the DA does not recognize its own business units as enterprises which require their own EA to completely integrate IT into the decision-making process and maximize the value of IT investments.
This paper examines one such business unit, human resources, and describes how an EA program can be developed that will nest neatly underneath the existing architecture for the DA and help optimize integrations, decrease IT risks, lower IT costs, and simplify the IT landscape.
EA-based review of US Department of Housing and Urban Development
By Dimitar Georgiev
In March 2012, the US Government Accountability Office (GAO) issued testimony about the increasing imbalance between the US Department of Housing and Urban Development’s (HUD) growing mission and its IT environment capabilities. GAO identified a lack of sound management controls such as IT strategic planning, investment management, enterprise architecture and human capital planning. Although between 2009 and 2012, HUD has made noticeable progress, some problems remain poorly addressed.
This paper takes a step further, looking at the GAO’s findings in more depth, in an attempt to extract and analyze more specific issues. This includes stove-piped, nonintegrated IT systems, a technology stack polluted with antiquated technologies, lack of architecture governance and controls, and lack of adequate metrics and key performance indicators (KPIs).
Application Landscape Views and SOA
By Borjan Cace
Subtitled “Ideas on dealing with challenges posed by the proliferation of services/API connections”, Borjan Cace presents a thoughtful paper showing ways of addressing the complexity that arises within organisations as they develop, expose and consume an ever-increasing number of services and API’s.
The paper demonstrates how ArchiMate might be used to assist in this process of understanding, and how the language might also be extended to provide even more meaning and insight to Enterprise Architects who must make sense of these complex and rapidly evolving environments. This includes a link to a great three dimensional viewing platform to bring your ArchiMate and other architecture models to life in a new way.
EA-based Assessment of Organizational Readiness for US 2020 Census
By Brianna Titone
The US Census is one of the most important facets of the US democracy which is mandated by the Constitution. The Census Bureau has been aggressively moving into the 21st century by implementing many new EA systems that will eventually save the Bureau billions for the decennial census. Budgetary constraints, insufficient training, and lack of leadership are hindering EA completion. At the current rate, EA systems will not be adequately tested before doing the decennial census. Without changes in management, training and budget investment, there is an uncertain future of the success of the 2020 Census.
Proposed EA Solutions for Industry 4.0 Manufacturing
By Cole Rogers
The vision of Industry 4.0 organizations involves complex highly integrated IT systems. This vision can strongly benefit from the fundamental principles of Enterprise Architecture that enable organizations to ‘achieve the right balance between IT efﬁciency and business innovation’ (The Open Group 2011). One aspect of the Industry 4.0 vision is the potential increased enterprise-wide usage of process simulations and virtual prototypes. These simulation-based information assets have traditionally been siloed within product development departments. Through the application of EA principles Industry 4.0 organizations can derive increased value from these assets by freeing them from their silos and increasing the potential for their application across the enterprise.
Leveraging Enterprise Architecture for Startup Organizations
By Andrea Pudlo
Enterprise Architecture (EA) can greatly benefit all kinds of organizations. However, companies that are in the developmental stage, like Airborne Wireless Networks (AWN), are in a unique position to reap even greater rewards from applying an EA framework to its initiatives. Ross, Weill, and Robertson (2006, 9) define EA as the “organizing logic” behind tying a company’s information technology (IT) infrastructure to its business processes with the ultimate goal of more effectively achieving current and future business objectives. Although a startup organization will not have accumulated an assortment of legacy systems and processes that make integration and standardization within a business difficult at best, this type of company can benefit by incorporating EA from day one to gain more business advantages.
Evolving Productivity with IT Asset Lifecycle Management and Configuration Management
By Brandon Rose
As the business grows, the tasks that were once tolerable, soon become burdensome. This is especially apparent in a business where silos prevent the true end-to-end view of work flows and processes. Asset and configuration management are two pain points that multiple business units participate in, but have constant hurdles due to its age, lack of automation and missing interactions with other vital applications.
