R1,408 Discovery Miles 14 080 Ships in 9 - 15 working days

Google's Programmable Search Engines (PSEs, previously called Custom Search Engines) provide search opportunities that are unavailable with any other tool. PSEs have advanced settings and search operators that are not supported by "regular" Google. With PSEs, it is possible to perform filtered searches within parts of the web as if they were databases! While lots of professionals use existing PSEs to source for talent or with other research goals, few people have experience creating them. Even fewer know about powerful PSE-only search operators. The main reason PSEs are not as popular as they should be is that it is not easy to get educated on PSE creation. There is little information online and no books (other than this one) on the subject. Even less info is available on the "structured" operators that allow for filtered searches. The first of its kind, this book hopes to popularize these fun and powerful tools so that many more people can include PSEs in their work. Key Features: A detailed introduction to creating PSEs, including info absent in Google's help A "hack" for creating PSEs that look for profiles in seconds An introduction to advanced PSE-only search operators allowed to perform filtered searches of parts of the web A "hack" for expanding Google's search limits to 500 terms Use cases, examples, and approaches that would be educational for those doing online research This book will be of interest to researchers, OSINT specialists, investigative journalists, Competitive Intelligence people, recruiters, and Sourcers, to name a few categories, and to the general public interested in how to search better.

After reviewing the benefits of identifying opportunities, the book steps through the opportunity identification and management process in detail, describing proven tools and techniques as well as specific tips to make them work in practice. The book places opportunity management in the context of traditional risk management, providing a familiar pathway that leads project managers to discover new benefits and successes. David Hillson is one of the foremost authorities on risk management. With his latest book he presents a strong case for managing opportunities. As with all of David's books, the style of writing is engaging and easy to understand. There are many nuggets of wisdom in this book, as well as a hands-on approach to leveraging opportunity management as a way of improving project performance. - Cyndi Snyder Dionisio, PMI Fellow, Coronado CA, USA. (Chair of the PMBOK (R) Guide, Sixth Edition) I enjoyed reading this book, which is precise, clear, logical, and persuasive. The clarity of thought and expression explains why David is such a sought-after speaker. This book is a must-read for project risk practitioners, as well as for project professionals who are serious about addressing all the risks on their project, including the good ones. - Dr Dale Cooper, Cammeray NSW, Australia. (Director, Broadleaf Capital International) At last, a clear and valuable book linking both sides of the coin in risk management: threats and opportunities. David Hillson truly engages the reader on how to deal with these two types of risk in projects, sharing his wisdom and extensive experience in creating value from risk management. Anyone who has to manage risk in real-world projects should read this book to enhance their opportunity management skills. - Professor Salim Al-Harthi, Muscat, Oman. (Director of Risk Management Office, Sultan Qaboos University) It is vital for value creation in business and in life that we consider uncertainties that would have upside impacts on our objectives (opportunities), as well as downside impacts (threats). Business gets confused between opportunities where there is a binary choice to take or not, and true uncertain opportunities that can be seized, or left to chance. David has persevered in helping us understand this and this important book is a must-read for all leaders who want to create value through the proactive management of risk. - Dr Ruth Murray-Webster, Wakefield, UK. (Partner, Beyond the Deal LLP and Editor, APM Body of Knowledge, 7th Edition) As project managers, we always seem to focus on threats, negative risks. David Hillson, one of the foremost thought-leaders on risk management, explains approaches to identify and manage opportunities, positive risks and how this will help achieve project success. As with his previous books, David provides a structured approach with examples, tools, and techniques.

Project or program health checks provide tremendous value to businesses and pay for themselves by multiples of magnitude. No matter how well a project or program is performing, there are always activities that can provide better value, reduce costs, or introduce more innovation. IT project and program health checks can help organizations reach their goals and dramatically improve Return on Investment (ROI). IT Project Health Checks: Driving Successful Implementation and Multiples of Business Value offers a proven approach for evaluating IT projects or programs in order to determine how they are performing and how the eventual outcome for the initiative is currently trending. The project or program health checks provide a set of techniques that produce actionable recommendations that can be applied for any combination of the following outcomes: Drive more business and technical value from a program Set a project or program back on track for successful implementation as defined by executive management Rescue a program that is heading towards failure Act as additional insurance for initiatives that are too important to fail Protect executive careers by creating transparency within the inner workings of complex initiatives. The book shows how a review can quickly identify whether an initiative needs to be rescued even when the project team is not aware that it is hurtling towards failure. It also provides techniques for driving business value even when a project team believes it's been stretched as much as possible. Other outcomes covered in this book include: Objectively develop a project Health-Check Scorecard that establishes how well a project is doing and the direction it is headed Demonstrate how to drive business value from an IT program regardless of how well or badly it is tracking Provide surgical advice to improve a project's outcome How to use the many templates and sample deliverables to get a quick start on your own health check. Designed to provide significant value to any member of a project team, program team, stakeholders, sponsors, business users, system integrators, trainers, and IT professionals, this book can help find opportunities to drive multiples of business value and exceed project success metrics.

Focusing on concepts and principles, rather than commercial offerings by cloud providers and vendors, The Cloud Computing Book: The Future of Computing Explained gives readers a complete picture of the advantages and growth of cloud computing, cloud infrastructure, virtualization, automation and orchestration, and cloud-native software design. The book explains real and virtual data center facilities, including computation (e.g., servers, hypervisors, Virtual Machines, and containers), networks (e.g., leaf-spine architecture, VLANs, and VxLAN), and storage mechanisms (e.g., SAN, NAS, and object storage). Chapters on automation and orchestration cover the conceptual organization of systems that automate software deployment and scaling. Chapters on cloud-native software cover parallelism, microservices, MapReduce, controller-based designs, and serverless computing. Although it focuses on concepts and principles, the book uses popular technologies in examples, including Docker containers and Kubernetes. Final chapters explain security in a cloud environment and the use of models to help control the complexity involved in designing software for the cloud. The text is suitable for a one-semester course for software engineers who want to understand cloud, and for IT managers moving an organization's computing to the cloud.

The Integrator - A Change Management Framework for Achieving Agile IT Project Success (Paperback): Scott Coplan The Integrator - A Change Management Framework for Achieving Agile IT Project Success (Paperback)

When a $145 million IT project failure pushes Los Angeles to the edge of financial meltdown, the County CEO asks Max McLellan, a harried IT project manager, aka The Integrator, for help. The County Board gives Max 30 days to identify the problem and find a solution. At first Max finds the usual missteps, but something bigger and darker beckons, an explosive source of project failure. He must do something different, rattling ghosts of previous County IT failures, uncloaking crookedness, and exposing truths that shatter careers. With some people rooting for his failure, Max battles to fit all the pieces together with the County team, applying his proven framework to define the problem, plan a solution and execute it successfully. It's common knowledge that barely 50% of IT projects succeed, per a 2017 Project Management Institute report. Equally well-known, approximately 70% of large-scale change management initiatives fail according to a 2017 McKinsey & Co. report. Given the challenge to overcome these low success rates, The Integrator offers a proven narrative on the organizational change framework for achieving Agile IT project management success based on the author's 45+ year client experiences and published research. The Integrator defines change management as the single overarching methodology integrating Agile IT and project management. It does this because all projects are about change - significant organizational and personal change. The people involved - their participation in and understanding and support of these changes - ultimately determine IT projects success or failure. In fact, while all IT projects are about change, successful projects change human behavior. The methodologies included in the framework, described in The Integrator, include: * Change management as defined by AIM (Accelerating Implementation Methodology). * Project management as defined by the Project Management Institute (PMI) Guide to the Project Management Body of Knowledge (PMBOK Guide) standard. * IT management as derived from the Institute of Electrical Engineers (IEEE) Guide to the Software Engineering Body of Knowledge (SWEBOK) standard. * Agile as defined by the Agile Alliance's Agile Manifesto. Written by a certified Project Management Professional and accredited change management practitioner, The Integrator chronicles the challenges involved in applying this framework in a real-world setting to achieve successful project implementation.

In this book, Edosa explores common challenges which limit the value that organisations can get from data. What makes his book unique is that he also tackles one of the unspoken barriers to data adoption-fear. Fear of the unknown, fear of the intangible, fear of the investment needed and, yes, fear of losing your job to a machine. With his talent for distilling clarity from complexity, Edosa tackles this and many other challenges. -Tim Carmichael, Chief Data Officer, Chalhoub Group This book offers fresh insight about how to solve the interactional frictions that hamper the flow of data, information and knowledge across organisations. Yet, rather than being stuck with endless polarising debates such as breaking down silos, it shifts focus back towards the ultimate "to what end." -Jacky Wright, Chief Digital Officer (CDO), Microsoft US If you care about AI transformation, empowering people or advancing organisational success in an increasingly digital world, then you should read this book. -Yomi Ibosiola, Chief Data and Analytics Officer, Union Bank A retail giant already struggling due to the Covid-19 pandemic was faced with a disastrous situation when-at the end of a critical investment in an artificial intelligence project that had been meant to save money-it suddenly discovered that its implementation was likely to leave it worse off. An entire critical service stream within an insurer's production system crashed. This critical failure resulted in the detentions of fully insured motorists for allegedly not carrying required insurance. Making Data Work details these two scenarios as well as others illustrating the consequences that arise when organizations do not know how to make data work properly. It is a journey to determine what to do to "make data work" for ourselves and for our organisations. It is a journey to discover how to bring it all together so organisations can enable digital transformation, empower people, and advance organisational success. It is the journey to a world where data and technology finally live up to the hype and deliver better human outcomes, where artificial intelligence can move us from reacting to situations to predicting future occurrences and enabling desirable possibilities.

Enterprise Agility - A Practical Guide to Agile Business Management (Paperback): Gizem Ozbayrac Enterprise Agility - A Practical Guide to Agile Business Management (Paperback)

Despite the astonishing technological developments in our times, it is surprising how little has changed in the way organizations are structured and managed. However, organizations are finally changing as they embark on agile transformations. Agility concepts emerged from the dynamics of project management and have evolved as they are being applied to organizational structure and operations. This phase of the agile evolution is known as enterprise agility. Filled with real-world scenarios and company case studies, Enterprise Agility: A Practical Guide to Agile Business Management covers the evolution of agility, including applied processes, lessons learned and realized outcomes. The book starts with the initial phase of the agile evolution, project agility and describes how waterfall project management is transformed into scrum, which can have positive effects on project timelines, scope and budget, as well as team motivation. The second phase of agility, organizational agility, is the evolution of the agile principles from temporary projects to permanent organizational structures. The book explains the main components of organizational agility, including structures, roles and ways of organizing work. It emphasizes the advantages of transitioning from traditional organizational management to agile. Finally, the latest phase, enterprise agility, transforms each function of the organization. The book acts as a guide and describes the change through the lens of each managerial domain (sales, marketing, HR, finance etc.) and by presenting the positive impact generated on the company's overall performance based on case studies. The last chapter illustrates the enablers of this transformation and how they can help the change to be internalized so that the enterprises realize improvements. The book is based on the author's over 15 years of experience of supporting more than 25 companies in varied sectors on their transformational journey, with the last 5 years concentrating on agility. By combining business management trends and principles of agile business development, it shows managers how to lead the transformation to enterprise agility by following the path from project agility to full enterprise agility.
