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 308 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.

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.

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 Cost Estimation in Agile Software Development written by Stefan Luckhaus and published by tredition. This book was released on 2016-08-15 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whenever software is developed based on contracts with binding agreed conditions it is exposed to risks; conditions such as the delivery of a clearly defined functional scope at a fixed price and at an agreed delivery date. Many of these risks can be mitigated by the principles of agile development. Being able to navigate projects within all agreed parameters requires cost estimation methods to be integrated into planning and controlling processes. In order to prevent these methods from eroding the advantages of agile development, they must be rapidly applicable - ideally automatable - and allow for self-calibration after every sprint. This book illustrates, how size metrics can be utilised profitably in software development processes oriented towards agile values. It points out differences and restrictions, how the accuracy of cost estimations can be increased with each sprint and examines the feasibility of automated measurements.

Download or read book Software Estimation Best Practices Tools Techniques written by Murali Chemuturi and published by J. Ross Publishing. This book was released on 2009-07-15 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Almost every software project begins with the utterances, “What will this cost?” and “When will this project be done?” Once those words are spoken, project stakeholders begin to wrestle with how to produce an estimate. Accurately estimating the cost or time to complete a software project is a serious problem for many software engineers, developers and project managers who struggle with costs running double original estimates, putting their careers at risk. It is reported that nearly 50% of all software projects are shelved and that one of the major causes is poor estimation practices. If developing software for internal use, poor estimates can represent a significant drain on corporate profits. Worldwide growth in the number of companies specializing in the development of software for use by other companies is staggering. India alone has nearly 20,000 such companies. Intense competition has led to an increased demand for fixed-bid pricing in client/vendor relationships, and has made effective cost estimation even more important and, in many cases, critical to a firm's survival. There are many methods of estimation. Each method has its strengths and weaknesses, proponents and opponents. Knowing how and which one to use on a given project is key to developing acceptable estimates for either internal or external projects.Software Estimation Best Practices, Tools, & Techniques covers all facets of software estimation. It provides a detailed explanation of the various methods for estimating software size, development effort, cost, and schedule, including a comprehensive explanation of Test Effort Estimation. Emphasizing that software estimation should be based on a well-defined process, it presents software estimation best practices and shows how to avoid common pitfalls. This guide offers direction on which methods are most appropriate for each of the different project types commonly executed in the software development space and criteria for selecting software estimation tools. This comprehensive desk reference explains software estimation from scratch to help the beginner and features advanced techniques for more experienced estimators. It details project scheduling, including resource leveling and the concept of productivity, as applicable to software estimators, demonstrating the many benefits of moving from the current macro-productivity approach to a micro-productivity approach in software estimation. Software Estimation Best Practices, Tools, & Techniques: A Complete Guide for Software Project Estimators caters to the needs of all software project stakeholders, from novice to expert. It provides the valuable guidance needed to estimate the cost and time required to complete software projects within a reasonable margin of error for effective software development.

Download or read book Estimating Packaged Software written by Eric van der Vliet and published by Nesma. This book was released on 2016-10-03 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: In software intensive organizations there is a trend towards less custom made software and an increasing use of packaged software. There is no generic framework for estimating the effort and cost of implementation and maintenance of packaged software. Each vendor and implementation partner uses its own proprietary techniques for estimation. This makes it hard to compare estimates from different sources or to build up benchmark data for public reference. Because of the many questions and discussions within the Nesma community about estimating implementation and maintenance of packaged software Nesma created an estimating framework that is presented in this guide. This document consists of three parts: Part 1: Packaged Software – Estimation ModelPart 2: Packaged Software – Cost DriversAppendices with practical examples to apply the Estimation Model
