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.

Effort estimation is used for planning and managing all phases of software development. Traditional estimation methods rely on having a mostly ?complete? and ?fixed? specification of a system. In agile software development, cost and effort estimation is challenging, as the requirements cannot be specified entirely upfront and are evolved as development progress and users interact with the product. Current practice in this context relies heavily on human judgment which has several limitations. It is based on limited information (subjective opinion), hampered by wishful thinking and prone to human judgment bias (individual and group effects). Estimates produced by these methods are often inaccurate. Experts recognize the need and importance of more objective information that includes historical data from previous iterations. Moreover, current estimation methods do not objectively consider the potential impact of a change on existing software and custom factors that contribute to the effort overhead. Thus, considerable improvement potential exists concerning systematic effort estimation in this environment and marks the contribution of this research to the body of knowledge.

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.

Agile Estimating and Planning is the definitive, practical guide to estimating and planning agile projects. In this book, Agile Alliance cofounder Mike Cohn discusses the philosophy of agile estimating and planning and shows you exactly how to get the job done, with real-world examples and case studies. Concepts are clearly illustrated and readers are guided, step by step, toward how to answer the following questions: What will we build? How big will it be? When must it be done? How much can I really complete by then? You will first learn what makes a good plan-and then what makes it agile. Using the techniques in Agile Estimating and Planning, you can stay agile from start to finish, saving time, conserving resources, and accomplishing more. Highlights include: Why conventional prescriptive planning fails and why agile planning works How to estimate feature size using story points and ideal days–and when to use each How and when to re-estimate How to prioritize features using both financial and nonfinancial approaches How to split large features into smaller, more manageable ones How to plan iterations and predict your team's initial rate of progress How to schedule projects that have unusually high uncertainty or schedule-related risk How to estimate projects that will be worked on by multiple teams Agile Estimating and Planning supports any agile, semiagile, or iterative process, including Scrum, XP, Feature-Driven Development, Crystal, Adaptive Software Development, DSDM, Unified Process, and many more. It will be an indispensable resource for every development manager, team leader, and team member.

Book Series: "Increasing Productivity of Software Development": In software development, productivity is a measure of how much functionality can be developed in a given time and in compliance with specified quality criteria. If an increase in productivity succeeds, this increases the scope of the developed functionality and reduces the required time. Both features are desirable because software is the stuff innovations are made of. IT has changed almost all areas of life thanks to fundamental innovations. Our future will be dominated by virtualization and smart helpers, that is, devices equipped with intelligence. This makes software development a key competence. Today, for companies that develop software, productivity as well as time and quality, are critical success factors. By introducing standards and automation, productivity in software development has been demonstrably increased by a factor of 20. The reutilization of functional and technical components has already enabled measurements of a factor of 100. Such performance differences are only reproducible by measurements and the consistent use of measurement results within a management model designed for continuous optimization. Part 2: Management Model, Cost Estimation and KPI Improvement: This book describes a model based on three key performance indicators: productivity (measured using the measurement methods described in the first book), cost and quality. It explains their cyclical collection, analytical evaluation and indicators that lead to improvement measures in important areas of influence. In order to be able to assess the benefits of the measures in advance, it provides empirical values as well as a method for calculating their effectiveness. The model described above serves as a navigation tool for the management, enabling them to constantly view both direction and speed of its key performance indicators.

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.

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.
