Book Synopsis Software Estimation Without Guessing by : George Dinwiddie
Download or read book Software Estimation Without Guessing written by George Dinwiddie and published by Pragmatic Bookshelf. This book was released on 2019-12-19 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estimating software development often produces more angst than value, but it doesn't have to. Identify the needs behind estimate requests and determine how to meet those needs simply and easily. Choose estimation techniques based on current needs and available information, gaining benefit while reducing cost and effort. Detect bad assumptions that might sink your project if you don't adjust your plans. Discover what to do when an estimate is wrong, how to recover, and how to use that knowledge for future planning. Learn to communicate about estimates in a healthy and productive way, maximizing advantage to the organization and minimizing damage to the people. In a world where most developers hate estimation and most managers fear disappointment with the results, there is hope for both. It requires giving up some widely held misconceptions. Let go of the notion that "an estimate is an estimate" and estimate for the particular need you, and your organization, have. Realize that estimates have a limited shelf-life, and reestimate frequently if it's important. When reality differs from your estimate, don't lament; mine that disappointment for the gold that can be the longer-term jackpot. Estimate in comparison to past experience, by modeling the work mathematically, or a hybrid of both. Learn strategies for effective decomposition of work and aspects of the work that likely affect your estimates. Hedge your bets by comparing the results of different approaches. Find out what to do when an estimate proves wrong. And they will. They're estimates, after all. You'll discover that you can use estimates to warn you of danger so you can take appropriate action in time. Learn some crucial techniques to understand and communicate with those who need to understand. Address both the technical and sociological aspects of estimation, and you'll help your organization achieve its desired goals with less drama and more benefit. What You Need: No software needed, just your past experience and concern for the outcomes.

Available in PDF, EPUB and Kindle. Book excerpt: Recommends an approach to improving the utility and accuracy of software cost estimates by exposing uncertainty (in understanding the project) and reducing the risks associated with developing the estimates. The approach focuses on characteristics of the estimation process (such as which methods and models are most appropriate for a given situation) and the nature of the data used (such as software size), describing symptoms and warning signs of risk in each factor, and risk-mitigation strategies.
Book Synopsis Software Cost Estimation, Benchmarking, and Risk Assessment by : Adam Trendowicz
Download or read book Software Cost Estimation, Benchmarking, and Risk Assessment written by Adam Trendowicz and published by Springer Science & Business Media. This book was released on 2013-01-10 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Software effort estimation is a key element of software project planning and management. Yet, in industrial practice, the important role of effort estimation is often underestimated and/or misunderstood. In this book, Adam Trendowicz presents the CoBRA method (an abbreviation for Cost Estimation, Benchmarking, and Risk Assessment) for estimating the effort required to successfully complete a software development project, which uniquely combines human judgment and measurement data in order to systematically create a custom-specific effort estimation model. CoBRA goes far beyond simply predicting the development effort; it supports project decision-makers in negotiating the project scope, managing project risks, benchmarking productivity, and directing improvement activities. To illustrate the method’s practical use, the book reports several real-world cases where CoBRA was applied in various industrial contexts. These cases represent different estimation contexts in terms of software project environment, estimation objectives, and estimation constraints. This book is the result of a successful collaboration between the process management division of Fraunhofer IESE and many software companies in the field of software engineering technology transfer. It mainly addresses software practitioners who deal with planning and managing software development projects as part of their daily work, and is also of interest for students or courses specializing in software engineering or software project management.
Book Synopsis Benefit/Cost-Driven Software Development by : Jo Erskine Hannay
Download or read book Benefit/Cost-Driven Software Development written by Jo Erskine Hannay and published by Springer Nature. This book was released on 2021 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book presents a set of basic techniques for estimating the benefit of IT development projects and portfolios. It also offers methods for monitoring how much of that estimated benefit is being achieved during projects. Readers can then use these benefit estimates together with cost estimates to create a benefit/cost index to help them decide which functionalities to send into construction and in what order. This allows them to focus on constructing the functionality that offers the best value for money at an early stage. Although benefits management involves a wide range of activities in addition to estimation and monitoring, the techniques in this book provides a clear guide to achieving what has always been the goal of project and portfolio stakeholders: developing systems that produce as much usefulness and value as possible for the money invested. The techniques can also help deal with vicarious motives and obstacles that prevent this happening. The book equips readers to recognize when a project budget should not be spent in full and resources be allocated elsewhere in a portfolio instead. It also provides development managers and upper management with common ground as a basis for making informed decisions.

Download or read book Software Project Effort Estimation written by Adam Trendowicz and published by Springer. This book was released on 2014-05-07 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: Software effort estimation is one of the oldest and most important problems in software project management, and thus today there are a large number of models, each with its own unique strengths and weaknesses in general, and even more importantly, in relation to the environment and context in which it is to be applied. Trendowicz and Jeffery present a comprehensive look at the principles of software effort estimation and support software practitioners in systematically selecting and applying the most suitable effort estimation approach. Their book not only presents what approach to take and how to apply and improve it, but also explains why certain approaches should be used in specific project situations. Moreover, it explains popular estimation methods, summarizes estimation best-practices, and provides guidelines for continuously improving estimation capability. Additionally, the book offers invaluable insights into project management in general, discussing issues including project trade-offs, risk assessment, and organizational learning. Overall, the authors deliver an essential reference work for software practitioners responsible for software effort estimation and planning in their daily work and who want to improve their estimation skills. At the same time, for lecturers and students the book can serve as the basis of a course in software processes, software estimation, or project management.

Software has become crucial to the very survival of civilization. But badly written, insecure software is hurting people–and costing businesses and individuals billions of dollars every year. This must change. In Geekonomics, David Rice shows how we can change it. Rice reveals why the software industry is rewarded for carelessness, and how we can revamp the industry’s incentives to get the reliability and security we desperately need and deserve. You’ll discover why the software industry still has shockingly little accountability–and what we must do to fix that. Brilliantly written, utterly compelling, and thoroughly realistic, Geekonomics is a long-overdue call to arms. Whether you’re software user, decision maker, employee, or business owner this book will change your life...or even save it.

Book Synopsis A Cost Model for Expressing and Estimating Ecological Costs of Software-Driven Systems by : Thomas Schulze
Download or read book A Cost Model for Expressing and Estimating Ecological Costs of Software-Driven Systems written by Thomas Schulze and published by BoD – Books on Demand. This book was released on 2017-08-23 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ecological footprint of our every day activities has become one of the greatest problems facing mankind today. Reducing the environmental footprint of IT, which has become a major contributor to green house gas emissions in the last decade, is therefore a major research challenge for both industry and academia. The focus of this book is to provide the foundation for expressing and estimating ecological costs of software systems in all life-cycle phases including the earliest phases of software development, thus helping all stakeholders make well-informed choices. In particular, common eco-cost drivers as well as new metrics are defined which allow meaningful and precise descriptions of ecological costs. Based on these concepts, auxiliary models are introduced which allow ecological costs and the circumstances causing them to be expressed in a unified, unambiguous, and easy-to-understand way. These models provide input to algorithmic eco-cost estimation models which show the impact of development decisions on ecological costs even in early phases of software development. Both the estimation and auxiliary models accommodate different input, allowing them to deliver the most accurate eco-cost estimates possible based on the information available. The approach presented in this book can therefore be used as the fulcrum of green software engineering methods to explore the eco-costs of applications' features and architectures at early stages in the development process before significant resources have been invested in their implementation. It therefore facilitates the creation of eco-friendlier software systems and by that contributing to the solution of one of the greatest problems facing mankind today.
