Digital transformation is a business concern; it is no longer just IT that must get things done. The disruptive force of start-ups focusing on IT-based services that can be consumed through mobile devices cannot be underestimated -- These start-ups eat away at the high-margin services provided by incumbents, leaving lower margin products and services that are rapidly being commoditized. This is happening in all industry sectors and it is the ones who are best able to adjust, innovate, and improve their service offerings that will survive. The question is: What do you need to do to ensure that your organization is one of the survivors? The core of the solution to the problem is to radically improve the way the IT organization works together with the business. To be clear, the digital transformation of your business depends on that relatively small group of people in the basement, or other out-of-the-way location, who make sure that your IT services work. So, building a cooperative model is vital for the success of the business. Which model has proven its worth in many industries? It is the application of Lean principles that gives organizations an advantage in delivering their products and services to their customers. Transforming your organization to high performance is, above all, a people-based movement with the acquisition and, most importantly, application of knowledge and skills necessary for the high performance way of working at its core. In teams, from boardroom to work floor, building a new way of thinking and acting is essential. This book aims to give insight into the reasons why you and your organization must consciously act to apply Lean principles to your IT organization. It explains the phases organizations go through as they start out with their initial attempts to gain advantages from Lean tools to the phase in which they reap the strategic benefits of Lean applied to IT. The real work of the transformation is described from two different perspectives: Leadership and Team. This book describes a complete set of principles, practices and tools In order to make the right decisions along the winding route of your transformation. The people who will guide, support and drive your transformation are the leaders and tem members who understand and apply those principles, practice and tools: your Lean IT Experts.

An effective blend of carefully explained theory and practical applications, this text imparts the fundamentals of both information theory and data compression. Although the two topics are related, this unique text allows either topic to be presented independently, and it was specifically designed so that the data compression section requires no prior knowledge of information theory.

The treatment of information theory, while theoretical and abstract, is quite elementary, making this text less daunting than many others. After presenting the fundamental definitions and results of the theory, the authors then apply the theory to memoryless, discrete channels with zeroth-order, one-state sources.

The chapters on data compression acquaint students with a myriad of lossless compression methods and then introduce two lossy compression methods. Students emerge from this study competent in a wide range of techniques. The authors' presentation is highly practical but includes some important proofs, either in the text or in the exercises, so instructors can, if they choose, place more emphasis on the mathematics.

Introduction to Information Theory and Data Compression, Second Edition is ideally suited for an upper-level or graduate course for students in mathematics, engineering, and computer science.

A fast-growing area in the communications industry is the internetworking of an ever-increasing proliferation of computers, particularly via local area networks (LANs). The LAN is a resource-sharing data communications network being used by many offices to interchange information such as electronic mail, word processing, and files among computers and other devices. This unique book shows the user how to establish the performance characteristics of a LAN before putting it to use in a particular type of situation. Simulation of Local Area Networks consists of eight chapters, each with its own extensive list of references. The first chapter provides a brief review of local area networks, and the second chapter gives the analytical models of popular LANs-token-passing bus and ring networks, CSMA/CD LANs, and star networks. Chapter 3 covers general principles of simulation, and Chapter 4 discusses fundamental concepts in probability and statistics relating to simulation modeling. Materials in Chapters 3 and 4 are specifically applied in developing simulation models on token-passing LANs, CSMA/CD LANs, and star LANs in Chapters 5 through 7. The computer code in Chapters 5, 6, and 7 is divided into segments, and a detailed explanation of each segment is provided. The last chapter reviews special-purpose languages such as GPSS, SIMSCRIPT, GASP, SIMULA, SLAM, and RESQ. Helpful criteria for language selection are included. The entire code is put together in the appendixes. This book has two major advantages over existing texts. First, it uses C, a well-developed general-purpose language that is familiar to most analysts. Second, the text specifically applies the simulation principles to local area networks.
