This book reveals how business and enterprise architects can deliver fast solutions to an always-on-the-go business world.To begin, you'll review a new technique called "context-space mapping," which provides a structured method for sense-making across the entire context of an enterprise.

A service-oriented architecture is fundamental to many new IT applications, from web development to social software and cloud computing. The same principles can be applied to every aspect of the service-oriented enterprise – not just in IT. In this book, you’ll explore how an enterprise architecture and viable services can link together to create a simpler yet far more powerful view of the enterprise, as a dynamic, unified whole. You can use the ideas, principles and methods described here in business transformation, workflow mapping, system design and much else besides, in every type of enterprise - including those in which there may be little or no IT at all. Step by step, you’ll walk through the basics of service-oriented architectures, the four key categories of services and how they connect, and how all of this comes together in real-world service design, implementation and operations. From this, you’ll discover how to identify and describe the different types ofservices that you need for your enterprise, and how to distinguish between the services that you can safely outsource, versus those that you do need to keep in-house. By the end of this book, you’ll learn how to construct function models and service models of your enterprise as a base for service-mapping, and how to pinpoint and map the information flows you need for service-management and service-performance, to keep everything on-track to purpose. What You'll LearnSee how an enterprise architecture can work as a literal architecture Understand Stafford Beer’s "Viable System Model" and adapt it as a robust modelStudy how a Viable Services Model provides a template for service design that covers functionals, non-functionals and operational governance for servicesWho This Book Is ForEnterprise architects, Business architects, Service designers, Workflow designers

One of the hardest tasks strategists and enterprise architects face is mapping an enterprise in a form that creates and supports making sense of the whole. This book introduces an alternate approach to create consistency at every level by modelling the enterprise as services with the Enterprise Canvas. This new model type that can be used to describe just about anything in any area and at any level of the enterprise, and that acts as a consistent frame for all the other models that we need in our architectures. It is also simple enough to scribble on the back of a napkin - and engage all of your stakeholders in the enterprise-scale conversations you need. There is also a simple notation for Enterprise Canvas that is suitable for use in service-design toolsets.The book teaches the use of architectural techniques to describe any aspect of the enterprise. It will help you identify the business reasons and business value for every activity, and you will also learn how to align strategy, tactics and operations to enterprise vision and values. By the end of this book, you will understand how an enterprise works as a web of services, and what needs to be done to make your enterprise work in the best possible way. What You'll LearnGain insight into the concepts of service to enhance agility, adaptability and resilience.Understand how to enhance efficiency and effectiveness throughout the enterprise.Grasp how an enterprise is made up of services that each serve an overall set of needs Who This Book Is ForEnterprise architects, Business architects, IT architects and process designers.
