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.

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.
Download or read book Systematic Review of Software Estimation written by Qamar Alam and published by LAP Lambert Academic Publishing. This book was released on 2012-08 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accurately estimating software size, cost, effort, and schedule is probably the biggest challenge facing software developers today. Traditional intuitive estimation methods have consistently produced optimistic results which contribute to the too familiar cost overrun and schedule slippage. It is observed that different methods give different results for the same inputs because many intangible of historical data and every software project will have its own unique features and cannot be compared with future projects. Experts suggest using more than one estimation method and analyzing the results before making a decision. An accurate estimate of software size is an essential element in the calculation of estimated project costs and schedules. In this paper we have taken different projects and estimate their effort using various models. We also used fuzzy logic approach.We also done its implementation.
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 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 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
