Innovative e-commerce ideas are characterised by commercial products yet unknown to the market, enabled by information technology such as the Internet and technologies on top of it. How to develop such products is hardly known. We propose an interdisciplinary approach, e3-value, to explore an innovative e-commerce idea with the aim of understanding such an idea thoroughly and evaluating it for potential profitability. Our methodology exploits a requirements engineering way of working, but employs concepts and terminology from business science, marketing and axiology. It shows how to model business requirements and improve business---IT alignment, in sophisticated multi-actor value constellations that are common in electronic commerce. In addition to the e3-value approach methodology, we also present the action research-based development of our methodology, by using one of the longitudinal projects we carried out in the field of online news article provisioning.

Value-based requirements engineering: exploring innovative e-commerce ideas

Advances in scientific computing have made modelling and simulation an important part of the decision-making process in engineering, science, and public policy. This book provides a comprehensive and systematic development of the basic concepts, principles, and procedures for verification and validation of models and simulations. The emphasis is placed on models that are described by partial differential and integral equations and the simulations that result from their numerical solution. The methods described can be applied to a wide range of technical fields, from the physical sciences, engineering and technology and industry, through to environmental regulations and safety, product and plant safety, financial investing, and governmental regulations. This book will be genuinely welcomed by researchers, practitioners, and decision makers in a broad range of fields, who seek to improve the credibility and reliability of simulation results. It will also be appropriate either for university courses or for independent study.

Verification and Validation in Scientific Computing

In this innovative book, Scott Ambler reviews how to: 1. Model on an XP project without detracting from its fast-moving and agile software development approach. 2. Simplify the modeling disciplines/workflows of the UP without losing any of the true benefits of those disciplines. 3. Use modeling to explore an issue or to facilitate communication. 4. Effectively apply the UML, and extend it with other methodologies, to meet your real-world development needs. 5. Reduce the documentation burden on your project by writing agile documents. 6. Use simple modeling tools, such as index cards and whiteboards, and know when to use complex CASE tools. 7. Rethink your approach to work areas, modeling teams, and modeling sessions.

Agile modeling: effective practices for extreme programming and the unified process

This article compares traditional requirements engineering approaches and agile software development. Our paper analyzes commonalities and differences of both approaches and determines possible ways how agile software development can benefit from requirements engineering methods.

Requirements engineering and agile software development

Scott Ambler, award-winning author of Building Object Applications that Work, Process Patterns, and More Process Patterns, has revised his acclaimed first book, The Object Primer. Long prized by both students and professionals as the best introduction to object-oriented technology, this book is now completely up-to-date, with all modeling notation rewritten in the just-released UML 2.0. All chapters have been revised to take advantage of Agile Modeling (AM), which is presented in the new chapter 2 along with other important new modeling techniques. Review questions at the end of each chapter allow readers to test their newly acquired knowledge. In addition, Ambler takes time to reflect on the lessons learned over the past few years by discussing the proven benefits and drawbacks of the technology. This is the perfect book for any software development professional or student seeking an introduction to the concepts and terminology of object technology. Previous Edition Pb (2001): 0-521-78519-7 Scott W. Ambler is a senior object consultant with Ronin International, Inc. and a popular speaker at conferences worldwide. He has worked with OO technology since 1990 as a business architect, system analyst, system designer, mentor, Smalltalk/C++/Java developer, and OO software process manager. He is a member of the IEEE Computer Society, the ACM, and Mensa.

The Object Primer: Agile Model-Driven Development with UML 2.0

From the Publisher:
Without formal, verifiable software requirements -- and an effective system for managing them -- the programs that developers think they've agreed to build often will not be the same products their customers are expecting. In Software Requirements, Second Edition, requirements engineering authority Karl Wiegers amplifies the best practices presented in his original award-winning text -- now a mainstay for anyone participating in the software development process. In this book, you'll discover effective techniques for managing the requirements engineering process all the way through the development cycle -- including dozens of techniques to facilitate that all-important communication between users, developers, and management. This updated edition features new case examples, anecdotes culled from the author's extensive consulting career, and specific Next Steps for putting the book's process-improvement principles into practice. You'll also find several new chapters, sample documents, and an incisive troubleshooting guide.
