This article utilises useful knowledge from the subject to build an enterprise architecture framework for a practical case study based on some methods and tools. There are variety frameworks to develop enterprise architecture (EA) that depends on different kinds of support in their offers (Jonkers, Quartel & Franken 2012). This article will focus on an integration of TOGAF-ADM as a guiding method (Lankhorst 2013), and Archimate 4.01 as a modelling language (Jonkers, Proper & Turner 2009) to design a specific model for an organisation in case study.

In general, the main parts of this article encompasses an overview of AusED’ background, and the five first step of TOGAF model and theirs links with Archimate language as illustrating different graphic diagrams as view points in three main layers consisting of business, application and technology.

There are some methods and tools, so that there are variety frameworks to develop enterprise architecture (EA) that depends on different kinds of support in their offers (Jonkers, Quartel & Franken 2012). This article will focus on an integration of TOGAF-ADM as a guiding method (Lankhorst 2013), and Archimate 4.01 as a modelling language (Jonkers, Proper & Turner 2009) to design a specific model for an organisation in case study.

AusED Background

AusED legally established in Australia with some main characteristics including corporation, non-profit and educational institution that were related to using all human resources and organisational finance to develop education, particularly higher education in information technology (IT) field.

In this field, AusED has a relationship with Australian Computer Society (ACS) defining the core framework of IT knowledge and skills of post-graduated IT course. AusED has four main business functions consisting of executive and operational management, sale and marketing management, courses delivery and special study centres in four different locations.

Phase A: Architecture Vision

In this step, TOGAF 9.1 and Archimate 4.0 were utilise to assist AusEd for developing an enterprise Architecture that leads the changes from the organisation’s business and information technology in future. This part is one of main components in Phase A that shows the key stakeholders of AusEd who engage and concern about vision. The definition of TOGAF standard is a Stakeholder Map matrix that represent in two main layers of Phase A consisting of enterprise goals (Appendix-H1) and enterprise concerns (Appendix-H2).

a. Stakeholder concerns

H1 represents a part of diagram, indicating five stakeholders (board director, operation managers, sale and marketing manager, course delivery manager and their customer as student) and their concerns, drivers.  Student satisfaction is identified as a shared concern of many stakeholders such as course delivery manager, board director and operation manager. Besides, stakeholder satisfaction can be pointed out into more detailed concerns, for example profitability.

b. Enterprise goals

In H2 diagram, there is more detailed information about how to achieve profitability by using principles. In order to obtain business goals, AusED utilises principles that assist them to direct to goals achievement in their educational activities. Principles have a role as cornerstones that direct organisation to meet its satisfactions as business goals (Greefhorst, & Proper 2011; Lam 2007; Lankhorst 2013).

Phase B: Business

In this Phase, the ArchiMate can illustrate and link AusEd organizational structure, products, services, functions, processes, and information (Lankhorst, Proper & Jonkers 2010). The Business Architecture gives the context for the Data, Application, and Technology Architectures. However, this report will focus on three main areas encompassing structure, functions and processes of AusEd.
