Report of the Third Measurement

1 Introduction

This report presents the results of the third electronic survey, executed by the Institute For Enterprise Architecture Developments (IFEAD) ©, on the progress of Enterprise Architecture (EA) usage & implementations in several organizations all over the world.

The Enterprise Architecture Survey's first edition was executed during 2003 and the results were presented during the LAC2003 conference in the Netherlands. A summary of the results is also present on the website of the Institute For Enterprise Architecture Developments; http://www.enterprise-architecture.info.

In the context of this report the definition of the term Enterprise Architecture is derived from the book 'How to survive in the jungle of Enterprise Architecture Frameworks' 1.

Definition: Enterprise Architecture is about understanding all of the different elements that go to make up the enterprise and how those elements inter- relate.

An Enterprise in this context is any collection of organizations that has a common set of goals/principles and/or single bottom line. In that sense, an enterprise can be a whole corporation, a division of a corporation, a government organization, a single department, or a network of geographically distant organizations linked together by common objectives.

Elements in this context are all the elements that enclose the areas of People, Processes, Business and Technology. In that sense, examples of elements are: strategies, business drivers, principles, stakeholders, units, locations, budgets, domains, functions, processes, services, information, communications, applications, systems, infrastructure, etc.

Filling in the EA survey 2005 at the website of IFEAD was voluntary, so the results can be a little bit distorted by the fact that only people who are interested in Enterprise Architecture are taking the effort to fill in this survey.

The survey was executed from September 2004 till September 2005.

In the following chapter, the context and scope of this study are elaborated. Afterwards, the result of the third measurement and the progress that has been achieved compared to the previous measurements is presented. In chapter 7 the overall observations and conclusions on how EA progressed in the last year are summarized. The symbol at the left is asking special attention from the reader for some remarkable observations.

2 The Enterprise Architecture Survey 2005 - Study

This third report is part of a yearly recurrent survey to measure the progress and developments in Enterprise Architecture. The report is based on a 25 questions survey, addressing geographical aspects, branch aspects, EA implementations aspects as well about tools and methodologies used in Enterprise Architecture programs and the role of architects in organizations. 79 respondents filled in the EA 2005 survey.

Where possible an overview will be given of the results of 2004 and 2003 and an analysis and explanation of exceptions. All geographic areas are represented in the survey as well as different sizes of organizations. All the source information is copyrighted and based on the EA Survey's 2005, 2004 and 2003 executed by the Institute For Enterprise Architecture Developments (IFEAD) 2005.

3.1.1 Analysis Comparing the 2005, 2004 and 2003 figures there are some significant changes between the 2005 and the 2004 / 2003 results.

Managing the IT portfolio is one of the up coming reasons for EA besides supporting decision making and delivering a roadmap for change . Managing complexity has slow down as one of the reasons for EA. There is no direct explanation for the shift between managing IT portfolio and managing complexity .

In the 2004 survey there was a strong growth for the item 'Transformation Road Map' as a reason for EA and a decline for the reason Business-IT Alignment . In 2005 Business-IT Alignment is back as number one reason, while Transformation Roadmap is almost at the same level as 2004. Infrastructure Renewal is showing a significant decline.

This diagram is showing the categories of organizations participating in this 2005 survey. A significant difference can be seen when comparing the organizations that participate in the 2005 survey with the 2004 survey. In 2005 more mid-size (25.000 – 50.000) multi-national organizations were participating and less smaller organizations (10.000 – 25.000). In 2005 we can see that Enterprise Architecture is present in all sizes of organizations.

Report of the Third Measurement

6.1.1 Analysis It's amazing to see the enormous growth of the usage of the Zachman’s Enterprise Architecture Framework compared to the 2004 results. Even so we can see that the organizations own EA frameworks are declining and that the presence of a well- known EA framework like the US Federal Enterprise Architecture Framework is declining dramatically. What you even so can see is that still a lot of organizations are defining their own EA framework, often based on existing ones. The use of TOGAF is growing slowly and new is the growth of the Extended Enterprise Architecture Framework. A lot of other EA frameworks are no longer present in the 2005 survey.

6.2.1 Analysis What we can see is a growth in the presence of Telelogic’s System Architect tool. Even so Microsoft Visio still have a constant and prominent position as Enterprise Architecture tools, while the Microsoft office tools are showing a decline. The MEGA tool set is in 2005 present is the EA survey.

6.3.1 Analysis New in the 2005 survey is the booming presence of BPML as business process modeling standard, while the IDEF family is coming back with a growth in 2005. There is even so a growth in organization own techniques compared to 2004 figures and a decline in other modeling techniques. Even the number of organizations that are not using any modeling tools is declining.

7 Trends in Enterprise Architecture 2005; Observations & Conclusions

7.1 Observations Enterprise Architecture is today widely spread among organizations all over the world. There is a strong progress in implementing Enterprise Architecture in countries like Japan, China, India, Iran, Russia and a lot of other countries. Enterprise Architecture is prominent present in large organizations as well as in small organizations (100 - 1000 employees). Enterprise Architecture is implemented in Governmental organizations as well as in several industries. E-Government is driving Enterprise Architecture progress and vice versa. Enterprise Architecture is used as Strategic Governance instrument, supporting decision making of management. Hot topics for using Enterprise Architecture are: Delivering road maps for change; Managing IT Portfolio; Managing Complexity and support of System Development. Enterprise Architecture is shifting from the responsibilities of the CIO to the responsibility of Board members and business managers. Every organization that is taken Enterprise Architecture serious has its own 'Enterprise' and other type of Architects. These Enterprise Architects can only be coached and mentored by external Enterprise Architects with a proven track record, knowledge of different kind of EA frameworks and a good reputation. Certification of Enterprise Architects is only an issue for consulting organizations and less at this time for organizations using Enterprise Architecture. More and more organizations are defining their own Enterprise Architecture Frameworks instead of adopting existing frameworks. The usage of Enterprise Architecture repository tools is growing; however most organizations still use Microsoft's office and Visio products for capturing their Enterprise Architecture results. The usage of standard business modeling techniques for modeling the results is broad accepted, where BPML is today the standard. OMG's Model Driven Architecture and UML are broad accepted for modeling Information-Systems.

7.2 Conclusions Every organization that wants to manage its complexity is taken Enterprise Architecture serious. The added value of Enterprise Architecture is NO discussion at all. The measurement in financial terms of this added value is still hard to do but some progress is achieved. The acceptance of Enterprise Architecture is growing fast in small and large organizations, in industry and government. The Enterprise Architects profession is still evolving and moving from the technology spectrum to the overall business spectrum. The need for formal EA education and training is growing, while the need for EA certification is at this time only present at consultancy firms.

Analyzing the EA 2005 survey results and understanding the drivers and behavior behind these results can help organizations to define their own Enterprise Architecture strategies and focus points. 33 Trends in Enterprise Architecture 2005: How are Organizations Progressing? © Copyright Institute For Enterprise Architecture Developments, 2005 – All Rights Reserved
