System and Software Quality Engineering: Some Application Contexts

This chapter discusses software quality engineering in the application context of two categories of software systems: the information systems subcategory of information management, and embedded systems. Information management systems are present in almost every domain of social life. Embedded systems are present in the life of almost every individual on the planet. Information management systems are systems that help the users better exploit and understand the information remaining in their access. The information management systems represent what employees use to execute their daily tasks. Commonly recognized categories of embedded systems include real-time interrupt-driven (RTID), mission-, or business-critical, and each have their sets of characteristics that position them on the scale of criticality.
