Structured Analysis and System Specification
This classic book of tools and methods for the analyst brings order and precisions to the specification process as it provides guidance and development of a structured specification. Covers functional decomposition; data dictionary; process specification; system modeling; structured analysis for a future system. Suitable for practicing systems analysts.
How to Engineer Software
A guide to the application of the theory and practice of computing to develop and maintain software that economically solves real-world problem How to Engineer Software is a practical, how-to guide that explores the concepts and techniques of model-based software engineering using the Unified Modeling Language. The author—a noted expert on the topic—demonstrates how software can be developed and maintained under a true engineering discipline. He describes the relevant software engineering practices that are grounded in Computer Science and Discrete Mathematics. Model-based software engineering uses semantic modeling to reveal as many precise requirements as possible. This approach separates business complexities from technology complexities, and gives developers the most freedom in finding optimal designs and code. The book promotes development scalability through domain partitioning and subdomain partitioning. It also explores software documentation that specifically and intentionally adds value for development and maintenance. This important book: Contains many illustrative examples of model-based software engineering, from semantic model all the way to executable code Explains how to derive verification (acceptance) test cases from a semantic model Describes project estimation, along with alternative software development and maintenance processes Shows how to develop and maintain cost-effective software that solves real-world problems Written for graduate and undergraduate students in software engineering and professionals in the field, How to Engineer Software offers an introduction to applying the theory of computing with practice and judgment in order to economically develop and maintain software.
Software Quality - ECSQ 2002
Software professionals and companies live in a new world today. Increasingly complex systems need to be built faster and cheaper. While many of the est- lished approaches in software quality are still valid, the software quality c- munity is going through a paradigm shift that requires a re-assessment of our current method and tool portfolio, as well as creating new and more e?ective solutions. We have selected two themes for this conference to highlight this paradigm shift. Our ?rst theme, “production of attractive and reliable software at Internet speed” sums up the dilemma many software organisations face. In order to be competitive, software should contain advanced features and run reliably – yet it should be developed quickly and cost e?ectively for the right market window. Finding the right balance between these objectives is a critical question that will determine business success in the years to come. Our second theme, “production of software with a dynamic partnership n- work” highlights the current trend of using partnerships and subcontractors as integral players in the software development process. Partnerships sometimes need to be created quickly to respond to a market opportunity, yet the costs and speed of cooperation must be competitive. Di?erent companies have di?erent processes, quality tools and cultures, yet they should cooperate seamlessly for the best result.
