Enterprise Architecture (EA) originated as a discipline to provide a view of an organisation in order to improve business-IT alignment. Enterprise Architecture evolved beyond business-IT alignment to a more holistic perspective to support organisations in meeting their current and future objectives. Enterprise Architecture is widely understood as visualising inherent structures of an organisation. Enterprise Architecture Management is a management approach that deals with planning and driving the corporate (digital) transformation.

Our personal Enterprise Architecture journey began in the year 2000 when we started to conduct university research in the field of Enterprise Modeling. While Bardo pursued an academic career as a professor at Deakin University (Melbourne, AU), Jrgen was following a career in industry as Enterprise Architect with Deutsche Post DHL in Germany. We maintained contact and continued our joint academic interest in Information Systems. Jrgen returned to academia in 2017 as Professor for Enterprise Architecture Management at the Frankfurt University of Applied Sciences. This academic reunion led to the joint introduction of Enterprise Architecture in both universities as part of the postgraduate Information Systems curriculum.

The textbook at hand originated from lecture notes from both courses. Based on these experiences, lecture recordings and transcripts as well as a script for Enterprise Architecture management, Bardo and Jrgen identified the need for a hands-on introduction to the topic. It is our teaching philosophy that Enterprise Architecture Management is best learned by sharing experiences and guiding students through the applications of methods and tools to typical business problems. The book is intended as a guide to conduct a Masterclass for Enterprise Architecture Management.

The structure of the book represents the typical stages of the journey of an Enterprise Architect. First, we address the central question for an Enterprise Architecture initiative in Chap. : What do we want to achieve with the introduction of Enterprise Architecture? Enterprise Architecture Management is about providing value to an organisation instead of simply applying a method or tool.

Chapter introduces concepts and visualisations for Business Architecture that help with understanding the business. Proven concepts like business capabilities and business objects are used as simple but powerful tools. These concepts cover a functional perspective on the business (business capabilities) together with a view on static entities (business objects). These are complemented by concepts to describe business motivation and business models.

A business capability map is used as a starting point for deriving an application landscape (as presented in Chap. ). Software applications are the counterpart to business capabilities as they implement desired functionality. In the same way, business objects reflect a high-level picture on data objects maintained by business software. Applications and data objects describe corporate information systems.

Business and Application Architecture are rather descriptive, providing transparency on information systems and their business context. They also provide the information required to analyse and improve the application landscape. Enterprise architects are using several visual tools to identify optimisation potential as depicted in Chap.. We introduce the business support matrix that is used to identify typical concerns in the application landscape.

A company is subject to frequent changes driven by changing business requirements and objectives. Such changes must be managed properly and require a corresponding organisational unit. Traditional organisational forms follow a top-down approachi.e. Enterprise Architecture Management is driven by top management. Recent experiences show that a more collaborative Enterprise Architecture Management approach is required. This discussion is presented in Chap..

We do not want to publish a textbook on Enterprise Architecture frameworks. However, frameworks are still relevant for any enterprise architect. Established frameworks are introduced in Chap..

We hope that you enjoy the Enterprise Architecture journey with us!
