Available in PDF, EPUB and Kindle. Book excerpt: Software cost estimation has been growing in importance till today. This is not a surprising fact that various difficulties are observed when estimating software costs. The major amount of the total costs of a project arises from the salaries of the personnel. Other costs, as license fees or new equipment for example, occur only once and are not too hard to estimate. Its a difficult task to measure software cost. These are various methods which were evolved time to time for cost estimation. A lots of examples of are given for cost estimation by different methods like Delphi, Analogy, COCOMO II etc.

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.
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.

Available in PDF, EPUB and Kindle. Book excerpt: Effective decisions are crucial to the success of any software project, but to make better decisions you need a better decision-making process. In Evaluating Project Decisions, leading project management experts introduce an innovative decision model that helps you tailor your decision-making process to systematically evaluate all of your decisions and avoid the bad choices that lead to project failure. Using a real-world, case study approach, the authors show how to evaluate software project problems and situations more effectively, thoughtfully assess your alternatives, and improve the decisions you make. Drawing on their own extensive research and experience, the authors bridge software engineering theory and practice, offering guidance that is both well-grounded and actionable. They present dozens of detailed examples from both successful and unsuccessful projects, illustrating what to do and what not to do. Evaluating Project Decisions will help you to analyze your options and ultimately make better decisions at every stage in your project, including: Requirements–Elicitation, description, verification, validation, negotiation, contracting, and management over the software life cycle Estimates–Conceptual solution design, decomposition, resource and overhead allocation, estimate construction, and change management Planning–Defining objectives, policies, and scope; planning tasks, milestones, schedules, budgets, staff and other resources; and managing projects against plans Product–Proper product definition, development process management, QA, configuration management, delivery, installation, training, and field service Process–Defining, selecting, understanding, teaching, and measuring processes; evaluating process performance; and process improvement or optimization In addition, you will see how to evaluate decisions related to risk, people, stakeholder expectations, and global development. Simply put, you’ll use what you learn here on every project, in any industry, whatever your goals, and for projects of any duration, size, or type.

Available in PDF, EPUB and Kindle. Book excerpt: On behalf of the PROFES Organizing Committee, we are proud to present to you the proceedings of the 9th International Conference on Product-Focused Software Process Improvement (PROFES 2008) held in Frascati - Monteporzio Catone, Rome, Italy. Since 1999, PROFES has established itself as one of the recognized international process improvement conferences. The main theme of PROFES is professional so- ware process improvement (SPI) motivated by product and service quality needs. Focussing on a product to be developed, PROFES 2008 addressed both quality en- neering and management topics including processes, methods, techniques, tools, - ganizations, and enabling SPI. Both solutions found in practice and the relevant research results from academia were presented. Domains such as the automotive and mobile applications industry are growing r- idly, resulting in a strong need for professional development and improvement. Nowadays, the majority of embedded software is developed in collaboration, and distribution of embedded software development continues to increase. Thus, PROFES 2008 addressed different development modes, roles in the value chain, stakeholders’ viewpoints, collaborative development, as well as economic and quality aspects. - ile development was included again as one of the themes. Since the beginning of the series of PROFES conferences, the purpose has been to bring to light the most recent findings and novel results in the area of process - provement, and to stimulate discussion among researchers, experienced professionals, and technology providers from around the world.

Available in PDF, EPUB and Kindle. Book excerpt: Inhaltsangabe:Einleitung: Software ist ein Produkt, dessen Preis nur schwer zu bestimmen ist. Die Softwareindustrie als Teil der so genannten New Economy kann mit alten Ideen der Kosten- und Preisberechnung nur wenig anfangen. Wissen gilt als wichtigster Produktionsfaktor und die Anpassung der Produkte an Kundenwünsche wird immer wichtiger. In diesem Umfeld ist es schwierig, Preis und Kosten an den Produktionsfaktoren festzumachen; Wissen ist schließlich kaum adäquat zu bewerten. Während die Distributionskosten (auch mit der weiten Verbreitung des Internets) immer geringer werden, können die Herstellungskosten enorme Ausmaße annehmen. Diese Ausmaße sind zudem besonders bei neuen Softwareprodukten, für die noch keine entsprechende Erfahrung vorhanden ist, schwierig abzuschätzen und explodierende Softwareentwicklungskosten haben schon die Fertigstellung einiger Projekte gefährdet oder sogar verhindert. Eine gute Abschätzung der Softwareentwicklungskosten ist daher bei jedem Projekt unumgänglich. Dazu gibt es bereits zahlreiche Softwaretools, die anhand einer Vielzahl von externen und internen Faktoren die Kosten abzuschätzen versuchen (z.B.: Costar, Cost Xpert). Allerdings sind diese Programme in erster Linie auf die Entwicklung neuer Software ausgerichtet und bieten meist nur wenig Unterstützung, wenn bereits bestehende Softwareproduktlinien eingeschätzt werden sollen. Zudem liegt bei diesen Modellen der Fokus auf einzelnen Produkten; Wiederverwendung wird oft nur unzureichend berücksichtigt. Bei Softwareproduktlinien werden mehrere Softwareprodukte zu Produktlinien zusammengefasst und teilweise gemeinsam entwickelt. Speziell die im Voraus geplante Wiederverwendung von Code in Softwareproduktlinien ist bei vielen Kostenmodellen nur ungenügend berücksichtigt. Dies führt zu einer unpräzisen Abschätzung der Kosten und damit auch zu einer Verzerrung des Return on Investment (ROI) beim Vergleich von Einzelentwicklung und Entwicklung im Rahmen einer Produktlinie. Um kosteneffziente Wiederverwendung zu ermöglichen, wird eine gemeinsame Software Plattform entwickelt, auf der die einzelnen Softwareprodukte aufbauen. Die Plattform enthält jene Komponenten der Software, die in mehreren Softwareprodukten verwendet werden. Wie dies im Mobilfunkbereich aussehen könnte, wurde exemplarisch in erläutert (siehe dazu auch Abschnitt 2.4). Bei einer bestehenden Softwareproduktlinie wäre es wünschenswert, wenn Verkauf und Marketing ein Werkzeug zur Hand haben, [...]

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.
