Systems Modeling and Requirements Specification Using ECSAM: An Analysis Method for Embedded and Computer-Based Systems

Discover ECSAM, a method for requirements engineering and the modeling of computer-based systems (CBS). Practiced since 1980 in evolving versions by systems and software engineers, ECSAM was developed in part at Israel Aircraft Industries for the analysis and design of complex reactive embedded systems and software and has been presented in numerous undergraduate, graduate, and industrial courses.

The method guides engineers in modeling operational, functional, and design requirements, considering both static and dynamic aspects of systems.

With an end-to-end example of the method, developed throughout the book, readers learn how to

* develop conceptual models of the structural and operational properties of computer-based systems and their software
* develop systematically operational scenarios and use cases describing the interaction of the system with its environment
* elicit and specify functional and nonfunctional requirements
* allocate requirements to components of a conceptual model and use the model for the refinement and derivation of requirements
* understand the issues of mapping the conceptual model to the design model

Core audiences include those involved in the development of complex or mission-critical computer-based systems and their software, systems engineers, computer-based-systems engineers, software engineers, engineering managers, and students at undergraduate and graduate levels.

Jonah Z. Lavi, the lead developer of ECSAM, consults and teaches industrial and university courses in the modeling and requirements specification of computer-based systems. He is the founding chair of the IEEE Computer Society ECBS Technical Committee and a laureate of the IEEE Computer Society Outstanding Contribution Award.

Joseph Kudish is an independent consultant specializing in systems and software engineering and in the appraisal and improvement of technical and management processes. He has researched, developed, taught, and implemented ECSAM in industrial projects since 1989.
