"The most interesting book ever written about Google" (The Washington Post) delivers the inside story behind the most successful and admired technology company of our time, now updated with a new Afterword. Google is arguably the most important company in the world today, with such pervasive influence that its name is a verb. The company founded by two Stanford graduate students-Larry Page and Sergey Brin-has become a tech giant known the world over. Since starting with its search engine, Google has moved into mobile phones, computer operating systems, power utilities, self-driving cars, all while remaining the most powerful company in the advertising business. Granted unprecedented access to the company, Levy disclosed that the key to Google's success in all these businesses lay in its engineering mindset and adoption of certain internet values such as speed, openness, experimentation, and risk-taking. Levy discloses details behind Google's relationship with China, including how Brin disagreed with his colleagues on the China strategy-and why its social networking initiative failed; the first time Google tried chasing a successful competitor. He examines Google's rocky relationship with government regulators, particularly in the EU, and how it has responded when employees left the company for smaller, nimbler start-ups. In the Plex is the "most authoritative...and in many ways the most entertaining" (James Gleick, The New York Book Review) account of Google to date and offers "an instructive primer on how the minds behind the world's most influential internet company function" (Richard Waters, The Wall Street Journal).

This book highlights the essence of information technology in the modern digital world in relation to improvements and threats to organisations and e-business in the era of the digital economy. Rapid IT development has created modern business proposals such as digital and virtual currencies, crowdfunding, peer-to-peer lending, mobile banking, online investing and new payment systems. This allows organisations and firms to increase competitiveness by using financial products and services, thus increasing their value. Information technology users receive significant timesaving and a choice of investment options. At the same time, there is a new challenge for regulators who must monitor how this or that technology affects the financial sector. The authors have collected and systematised information on the models of using information technology in e-business as well as issues of applying information technology in smart organisations and public institutions. The book addresses the issues of risk management in organizations and the problems of personal and social risks resulting from the use of information technology. In addition, the book presents a review of e-commerce sectors and models as well as e-commerce tools, international payment systems and modern money systems. Risks, threats and security rules for using banking services, e-commerce and payment systems are reviewed and systematised.

Managers in organisations must make rational decisions. Rational decision making is the opposite of intuitive decision making. It is a strict procedure utilising objective knowledge and logic. It involves identifying the problem to solve, gathering facts, identifying options and outcomes, analysing them, considering all the relationships and selecting the decision. Rational decision making requires support: methods and software tools. The identification of the problem to solve needs methods that would measure and evaluate the current situation. Identification and evaluation of options and analysis of the available possibilities involves analysis and optimisation methods. Incorporating intuition into rational decision making needs adequate methods that would translate ideas or observed behaviours into hard data. Communication, observation and opinions recording is hardly possible today without adequate software. Information and data that form the input, intermediate variables and the output must be stored, managed and made accessible in a user-friendly manner. Rational Decisions in Organisations: Theoretical and Practical Aspects presents selected recent developments in the support of the widely understood rational decision making in organisations, illustrated through case studies. The book shows not only the variety of perspectives involved in decision making, but also the variety of domains where rational decision support systems are needed. The case studies present decision making by medical doctors, students and managers of various universities, IT project teams, construction companies, banks and small and large manufacturing companies. Covering the richness of relationships in which the decisions should and must be taken, the book illustrates how modern organisations operate in chains and networks; they have multiple responsibilities, including social, legal, business and ethical duties. Nowadays, managers in organisations can make transparent decisions and consider a multitude of stakeholders and their diverse features, incorporating diverse criteria, using multiple types and drivers of information and decision-making patterns, and referring to numerous lessons learned. As the book makes clear, the marriage of theoretical ideas with the possibilities offered by technology can make the decisions in organisations more rational and, at the same time, more human.

This book addresses the important role of communication within the context of performing an audit, project, or review (i.e., planning, detailed testing, and reporting). Intended for audit, information security, enterprise, and operational risk professionals at all levels, including those just starting out, Say What!? Communicate with Tact and Impact: What to Say to Get Results at Any Point in an Audit contains an array of practical and time-tested approaches that foster efficient and effective communication at any point during an engagement. The practical and memorable techniques are culled from author Ann M. Butera's CRP experience as a trusted advisor who has taught thousands of professionals how to develop and hone their interpersonal, communication, and empathic skills. Those familiar with the Five Tier Competency ModelTM she developed will recognize these techniques as a deep dive on the competencies comprising Tier 3: Project Management and Tier 5: Managing Constituent Relations. The author discusses the following behaviors in one's dealings with executives, process owners, control performers, and colleagues: Demonstrating executive presence Becoming the trusted advisor Influencing others Communicating with tact, confidence, and impact Facilitating productive meetings and discussions Overcoming resistance and objections Managing and resolving conflict Knowing when to let a topic go and move on This book is a guide for professionals who want to interact proactively and persuasively with those they work with, audit, or review. It describes techniques that can be used during virtual, in-person, telephone, or video conferences (as opposed to emails, workpapers, and reports). It provides everyone (newer associates in particular) with the interpersonal skills needed to (1) develop and build relationships with their internal constituents and clients, (2) facilitate conversations and discussions before and during meetings, and (3) handle impromptu questions with confidence and executive presence and make positive first impressions. The topics and techniques discussed are accompanied by case studies, examples, and exercises to give the readers the opportunity to develop plans to bridge the gap between theory and practice. The readers can use the book as a reliable resource when subject matter experts or training guides are not readily available.

The Lean Approach to Digital Transformation: From Customer to Code and From Code to Customer is organized into three parts that expose and develop the three capabilities that are essential for a successful digital transformation: 1. Understanding how to co-create digital services with users, whether they are customers or future customers. This ability combines observation, dialogue, and iterative experimentation. The approach proposed in this book is based on the Lean Startup approach, according to an extended vision that combines Design Thinking and Growth Hacking. Companies must become truly "customer-centric", from observation and listening to co-development. The revolution of the digital age of the 21st century is that customer orientation is more imperative -- the era of abundance, usages rate of change, complexity of experiences, and shift of power towards communities -- are easier, using digital tools and digital communities. 2. Developing an information system (IS) that is the backbone of the digital transformation - called "exponential information system" to designate an open IS (in particular on its borders), capable of interfacing and combining with external services, positioned as a player in software ecosystems and built for processing scalable and dynamic data flows. The exponential information system is constantly changing and it continuously absorbs the best of information processing technology, such as Artificial Intelligence and Machine Learning. 3. Building software "micro-factories" that produce service platforms, which are called "Lean software factories." This "software factory" concept covers the integration of agile methods, tooling and continuous integration and deployment practices, a customer-oriented product approach, and a platform approach based on modularity, as well as API-based architecture and openness to external stakeholders. This software micro-factory is the foundation that continuously produces and provides constantly evolving services. These three capabilities are not unique or specific to this book, they are linked to other concepts such as agile methods, product development according to lean principles, software production approaches such as CICD (continuous integration and deployment) or DevOps. This book weaves a common frame of reference for all these approaches to derive more value from the digital transformation and to facilitate its implementation. The title of the book refers to the "lean approach to digital transformation" because the two underlying frameworks, Lean Startup and Lean Software Factory, are directly inspired by Lean, in the sense of the Toyota Way. The Lean approach is present from the beginning to the end of this book -- it provides the framework for customer orientation and the love of a job well done, which are the conditions for the success of a digital transformation.

Asynchronous On-Chip Networks and Fault-Tolerant Techniques is the first comprehensive study of fault-tolerance and fault-caused deadlock effects in asynchronous on-chip networks, aiming to overcome these drawbacks and ensure greater reliability of applications. As a promising alternative to the widely used synchronous on-chip networks for multicore processors, asynchronous on-chip networks can be vulnerable to faults even if they can deliver the same performance with much lower energy and area compared with their synchronous counterparts - faults can not only corrupt data transmission but also cause a unique type of deadlock. By adopting a new redundant code along with a dynamic fault detection and recovery scheme, the authors demonstrate that asynchronous on-chip networks can be efficiently hardened to tolerate both transient and permanent faults and overcome fault-caused deadlocks. This book will serve as an essential guide for researchers and students studying interconnection networks, fault-tolerant computing, asynchronous system design, circuit design and on-chip networking, as well as for professionals interested in designing fault-tolerant and high-throughput asynchronous circuits.

This book introduces a generic and systematic design-time/run-time methodology for handling the dynamic nature of modern embedded systems, without adding large safety margins in the design. The techniques introduced can be utilized on top of most existing static mapping methodologies to deal effectively with dynamism and to increase drastically their efficiency. This methodology is based on the concept of system scenarios, which group system behaviors that are similar from a multi-dimensional cost perspective, such as resource requirements, delay, and energy consumption. Readers will be enabled to design systems capable to adapt to current inputs, improving system quality and/or reducing cost, possibly learning on-the-fly during execution. Provides an effective solution to deal with dynamic system design Includes a broad survey of the state-of-the-art approaches in this domain Enables readers to design for substantial cost improvements (e.g. energy reductions), by exploiting system scenarios Demonstrates how the methodology has been applied effectively on various, real design problems in the embedded system context
