Book Description

Enterprise Architecture (EA) is an essential part of the fabric of a business; however, EA also transcends and transforms technology and moves it into the business space. Therefore, EA needs to be discussed in an integrated, holistic, and comprehensive manner. Only such an integrated approach to EA can provide the foundation for a transformation that readies the business for the myriad enterprise-wide challenges it will face. Highly disruptive technologies such as Big Data, Machine Learning, and Mobile and Cloud Computing require a fine balance between their business and technical aspects as an organization moves forward with its digital transformation. This book focuses on preparing all organizations – large and small – and those wishing to move into them for the impact of leveraging these emerging, disruptive, and innovative technologies within the EA framework.

"From the Board and the executive, through operations, to out-sourced functions, technologies like artificial intelligence, machine-to-machine learning, and Big Data Analytics along with cloud services are transforming business. Knowledge worker services are being automated, increased information dependencies are seen, risk profiles revised, markets changing, and cost savings to be had. To make these integrated changes, a strategic but pragmatic incremental approach with the necessary governance, organizational change, and architecture is used. It is in the pragmatics of architecture against strategy in which this book brings an integrated approach to transformation."
