First of all, I would like to thank my girl, Verónica, for her essential support while writing this book. Without you, this manuscript would have been simply impossible. But, most importantly, thank you for sharing your life with me. I would also like to thank to my sisters, Yoly and Inma, for all their help, not only with this book, but in life in general. Thank you for being always there. In addition, I want to dedicate this book to my nieces, Andrea, Silvia, and Laura, who are the most amazing people in the universe (at least the part I know). I also would like to remember here my parents, Pablo and Dolores. There is nothing I would like more than if you were here. I know that a part of you is living with us, in your daughters, grandchildren, and myself. I miss you so much. Finally, I also want to dedicate this book to the most important person in the world, my little boy, Pablo. Son, whenever you read this, I want you to know that I learned what happiness really means by looking into your eyes. I would like to believe these words can travel in time and space to give you a big hug anytime. Remember that your parents love you more than anything. About the Reviewers Luis Fernández Muñoz in the last 25 years he has been serving as a Professor and Researcher at Technical University of Madrid (UPM) and King Juan Carlos University (URJC), both in Spain. he has also collaborate as Consultor and Trainer in different public and private national and international institutions. His main expertise comprises all the software engineering disciplines, from coding and testing, to analysis, design, architecture, and project management, usually around C++/Java and Web/JEE technologies. As a Consultor in private companies, he has participated in different projects as different roles, from management to development of code and tests. In the different areas he has worked, he highlight cloud computing, combat simulation and physical activity expert systems, among others.

  • Survey of Verification and Validation Techniques for Small Satellite Software Development
    Survey of Verification and Validation Techniques for Small Satellite Software Development Stephen A. Jacklin NASA Ames Research Center Presented at the 2015 Space Tech Expo Conference May 19-21, Long Beach, CA Summary The purpose of this paper is to provide an overview of the current trends and practices in small-satellite software verification and validation. This document is not intended to promote a specific software assurance method. Rather, it seeks to present an unbiased survey of software assurance methods used to verify and validate small satellite software and to make mention of the benefits and value of each approach. These methods include simulation and testing, verification and validation with model-based design, formal methods, and fault-tolerant software design with run-time monitoring. Although the literature reveals that simulation and testing has by far the longest legacy, model-based design methods are proving to be useful for software verification and validation. Some work in formal methods, though not widely used for any satellites, may offer new ways to improve small satellite software verification and validation. These methods need to be further advanced to deal with the state explosion problem and to make them more usable by small-satellite software engineers to be regularly applied to software verification. Last, it is explained how run-time monitoring, combined with fault-tolerant software design methods, provides an important means to detect and correct software errors that escape the verification process or those errors that are produced after launch through the effects of ionizing radiation. Introduction While the space industry has developed very good methods for verifying and validating software for large communication satellites over the last 50 years, such methods are also very expensive and require large development budgets.

  • Patterns for Implementing Software Analytics in Development Teams
    Patterns for Implementing Software Analytics in Development Teams JOELMA CHOMA, National Institute for Space Research - INPE EDUARDO MARTINS GUERRA, National Institute for Space Research - INPE TIAGO SILVA DA SILVA, Federal University of São Paulo - UNIFESP The software development activities typically produce a large amount of data. Using a data-driven approach to decision making – such as Software Analytics – the software practitioners can achieve higher development process productivity and improve many aspects of the software quality based on the insightful and actionable information. This paper presents a set of patterns describing steps to encourage the integration of the analytics activities by development teams in order to support them to make better decisions, promoting the continuous improvement of software and its development process. Before any procedure to extract data for software analytics, the team needs to define, first of all, their questions about what will need to be measured, assess and monitored throughout the development process. Once defined the key issues which will be tracked, the team may select the most appropriate means for extracting data from software artifacts that will be useful in decision-making. The tasks to set up the development environment for software analytics should be added to the project planning along with the regular tasks. The software analytics activities should be distributed throughout the project in order to add information about the system in small portions. By defining reachable goals from the software analytics findings, the team turns insights from software analytics into actions to improve incrementally the software characteristics and/or its development process. Categories and Subject Descriptors: D.2.8 [Software and its engineering]: Software creation and management—Metrics General Terms: Software Analytics Additional Key Words and Phrases: Software Analytics, Decision Making, Agile Software Development, Patterns, Software Measurement, Development Teams.

  • Evaluating and Improving Software Quality Using Text Analysis Techniques - a Mapping Study
    Evaluating and Improving Software Quality Using Text Analysis Techniques - A Mapping Study Faiz Shah, Dietmar Pfahl Institute of Computer Science, University of Tartu J. Liivi 2, Tartu 50490, Estonia {shah, dietmar.pfahl}@ut.ee Abstract: Improvement and evaluation of software quality is a recurring and crucial activ- ity in the software development life-cycle. During software development, soft- ware artifacts such as requirement documents, comments in source code, design documents, and change requests are created containing natural language text. For analyzing natural text, specialized text analysis techniques are available. However, a consolidated body of knowledge about research using text analysis techniques to improve and evaluate software quality still needs to be estab- lished. To contribute to the establishment of such a body of knowledge, we aimed at extracting relevant information from the scientific literature about data sources, research contributions, and the usage of text analysis techniques for the im- provement and evaluation of software quality. We conducted a mapping study by performing the following steps: define re- search questions, prepare search string and find relevant literature, apply screening process, classify, and extract data. Bug classification and bug severity assignment activities within defect manage- ment are frequently improved using the text analysis techniques of classifica- tion and concept extraction. Non-functional requirements elicitation activity of requirements engineering is mostly improved using the technique of concept extraction. The quality characteristic which is frequently evaluated for the prod- uct quality model is operability. The most commonly used data sources are: bug report, requirement documents, and software reviews. The dominant type of re- search contributions are solution proposals and validation research.

What makes it stand out from the crowd is its beautiful and highly expressive specification language.
