Available in PDF, EPUB and Kindle. Book excerpt: Organizational change for IT people! The first book of its kind written specifically for IT service management practitioners and executives. Most IT organizational structures are falling out of date with the shifts created by the introduction of new technologies, expanding services, pace of business change, and the overall trend of lifting IT up and out of the traditional data center and into the cloud. This is about transitioning the IT organization from engineering silos providing capabilities to valued IT services that deliver business value. IT organizations embarking on IT service management must address both cultural and structural barriers in a way that involves the whole enterprise if they are going to be successful. Readers of this book will find practical guidance for transitioning to the people and culture side of IT service management. It identifies pros and cons of different IT organizational models, how to deal with resistance, building a communications plan step-by-step, training considerations, and much more.

Book excerpt: Architecture and Patterns for IT Service Management, Resource Planning, and Governance: Making Shoes for the Cobbler's Children provides an independent examination of developments in Enterprise Resource Planning for Information. Major companies, research firms, and vendors are offering Enterprise Resource Planning for Information Technology, which they label as ERP for IT, IT Resource Planning and related terms. This book presents on-the-ground coverage of enabling IT governance in architectural detail, which can be used to define a strategy for immediate execution. It fills the gap between high-level guidance on IT governance and detailed discussions about specific vendor technologies. It provides a unique value chain approach to integrating the COBIT, ITIL, and CMM frameworks into a coherent, unified whole. It presents a field-tested, detailed conceptual information model with definitions and usage scenarios, mapped to both process and system architectures. This book is recommended for practitioners and managers engaged in IT support in large companies, particularly those who are information architects, enterprise architects, senior software engineers, program/project managers, and IT managers/directors.

Book excerpt: Information Systems (IS) as a discipline draws on diverse areas including, technology, organisational theory, management and social science. The field is recognized as very broad and encompassing many themes and areas. However, the development of artefacts, or information systems development (ISD), in the broadest sense, is a central concern of the discipline. Significantly, ISD impacts on the organisational and societal contexts through the use of the artefacts constructed by the development. Today, that impact also needs to be evaluated in terms of its effects on the environment. Sustainable, or "green," IT is a catch-all term used to describe the development, manufacture, management, use and disposal of ICT in a way that minimizes damage to the environment. As a result, the term has many different meanings, depending on the role assumed in the life span of the ICT artefact. The theme of the proposed work is to critically examine the whole range of issues around ISD from the perspective of sustainability. Sustainable IT is an emerging theme in academic research and industry practice in response to an individual concern for the environment and the embryonic regulatory environments being enacted globally to address the environmental impact of ICT. In this work we intend to bring together in one volume the diverse research around the development of sustainable IS.

Available in PDF, EPUB and Kindle. Book excerpt: In only 15 years the role of information in our society has changed dramatically. We are in the middle of an information revolution guided by the need to put the right information in the right people’s hands at the right time. Information flows within and between organisations as if there are no boundaries between them. It requires infrastructures built on open standards and designed to enable individuals as well as their IT systems to all work together. Managers have to make decisions on the investments they make in information provision. These decisions have become complex and must be taken more often and faster than ever before. Enterprise Architecture is a maturing profession that can help management to understand this growing complexity. Enterprise Architecture can reduce complexity by making plans schemes and designs of the organisation and its information systems and the infrastructure it runs on and therefore emerges as a true profession. TOGAF the Open Group Architectural Framework is a fast growing, worldwide accepted standard that can help organisations build their own Enterprise Architecture in a standardised way. This book explains why this upcoming profession is important and what TOGAF can do to support you and your organisation. This book explains to management how TOGAF can help to make an Enterprise Architecture.

Simply stated, the goal of DSR is to generate knowledge on how to find innovative solutions to important problems in the form of models, methods, constructs and instantiations. Over the past 20 years, the design science research (DSR) paradigm has developed into an established paradigm in Information Systems Research and it is of strong uptake in many other disciplines, including Management Science and Computer Science. This book provides a collection of twelve DSR cases, presented by experienced researchers in the field. It offers readers access to real-world DSR studies, together with the authors’ reflections on their research processes. These cases will support researchers who want to engage in DSR, and represent a valuable addition to existing introductions to DSR methods and processes. Readers will learn from the hands-on experiences of respected experts who have conducted extensive DSR in a range of application contexts.
