Strategic IT Portfolio Management

Strategic IT Portfolio Management delivers a solution to the IT dilemma that has evolved over the past 40 years – namely, how do we get the most value from our IT investment? Author Jeff Kaplan, a lead partner in the Strategic IT Management Practice at consulting firm PRTM, puts nearly two decades of expertise to work exploring and identifying the knowledge, techniques, and strategies needed to maximize technology investments and achieve long-term business transformation for all types of organizations. Written for executives from all disciplines, the book highlights many of the root causes of the IT value dilemma and explains how executives can prevent and counter these issues. Readers will learn the portfolio management methods essential to achieving value. The book provides executives with the tools to: – Illuminate, assess, and improve existing practices – Design a governance structure and allocate appropriate decision rights – Ensure centralized control with decentralized execution – Increase collaboration between business-unit and IT leadership – Instill a culture of continuous improvement and innovation Executives, board members, policymakers, analysts, and the media all want to know: are companies spending too much on information technology (IT)? But the question they should ask is whether organizations are seeing sufficient value from their IT investment – the value that comes from effectively managing technology as part of overall business transformation. Many organizations don’t know how to move from managing technology to managing overall business transformation. Large-scale transformation efforts often go awry because the business leadership team and IT project teams are out of sync. In most of these cases, the organization lacks a governance method that fuses strategic management of the business, the technology, and the projects. Portfolio management is the governance method that’s needed. Strategic IT Portfolio Management describes the portfolio management governance method necessary for transformation success. This book highlights many of the root causes for the IT dilemma and explains how executives can prevent and counter these issues. Readers gain an inside look at how portfolio management can instill a culture of continuous improvement and innovation within the organization.

Enterprise Architecture As Strategy: Creating a Foundation for Business Execution

Enterprise architecture defines a firm’s needs for standardized tasks, job roles, systems, infrastructure, and data in core business processes. Thus, it helps a company to articulate how it will compete in a digital economy and it guides managers’ daily decisions to realize their vision of success. This book clearly explains enterprise architecture’s vital role in enabling – or constraining – the execution of business strategy. The book provides clear frameworks, thoughtful case examples, and a proven-effective structured process for designing and implementing effective enterprise architectures.

Lightweight Enterprise Architectures

The author developed Lightweight Enterprise Architecture (LEA) to enable a quick alignment of technology to business strategy. LEA’s simple and effective framework makes it useful to a wide audience of users throughout an enterprise, coordinating resources for business requirements and facilitating optimal adoption of technology. Lightweight Enterprise Architectures provides a methodology and philosophy that organizations can easily adopt, resulting in immediate value-add without the pitfalls of traditional architectural styles. This systematic approach uses the right balance of tools and techniques to help an enterprise successfully develop its architecture. The first section of the text focuses on how enterprises deploy architecture and how architecture is an evolving discipline. The second section introduces LEA, detailing a structure that supports architecture and benefits all stakeholders. The book concludes by explaining the approach needed to put the framework into practice, analyzing deployment issues and how the architecture is involved throughout the lifecycle of technology projects and systems. This innovative resource tool provides you with a simpler, easily executable architecture, the ability to embrace a complex environment, and a framework to measure and control technology at the enterprise level.

Dynamic Enterprise Architecture: How to Make It Work

This book presents an approach to enterprise architecture, which enables corporations to achieve their business objectives faster. Focusing on the governance of IT in the organization, it provides tangible tools, advice and strategies for implementing and designing the architectural process within a corporation that will make a major contribution in driving the business forward and achieve its goals.

The Practical Guide to Enterprise Architecture

The role of the enterprise architecture professional is one of the most challenging roles in information technology today. Many aspects of the role are technical, while much more of the job is becoming political. To say the least, it is a challenging position. Many enterprise architects have significant responsibility, but do not have the necessary authority to bring about success. The primary focus of this book is to be a guide and trusted advisor to those who want to be successful in this pursuit. Through real-world examples from experts who have filled the role of enterprise architect, the reader will learn how to solve complex problems, maintain technical competencies, and make a positive impact on the overall business. The most successful architecture will have an architect that can describe the motivation behind the technical choices; this book provides the background the practitioners will need to become the enterprise evangelist.

Enterprise Architecture at Work: Modelling, Communication and Analysis

An enterprise architecture tries to describe and control an organisation’s structure, processes, applications, systems and techniques in an integrated way. The unambiguous specification and description of components and their relationships in such an architecture requires a coherent architecture modelling language. Lankhorst and his co-authors present such an enterprise modelling language, ArchiMate, that captures the complexity of architectural domains and their relations and allows the construction of integrated enterprise architecture models. They provide architects with concrete instruments that improve their architectural practice. As this is not enough, they additionally present techniques and heuristics for communicating with all relevant stakeholders about these architectures. Since an architecture model is useful not only for providing insight into the current or future situation but can also be used to evaluate the transition from ‘as-is’ to ‘to-be’, the authors also describe analysis methods for assessing both the qualitative impact of changes to an architecture and the quantitative aspects of architectures, such as performance and cost issues. The modelling language and the other techniques presented have been proven in practice in many real-life case studies. So this book is an ideal companion for enterprise IT or business architects in industry as well as for computer or management science students studying the field of enterprise architecture.
