Understandability, usability, robustness and survivability

Abstract

The design of systems and components during the design stage of the systems life cycle requires specific purposeful actions to ensure effective designs and viable systems. Designers are faced with a number of core viability concerns that they must embed into the design to ensure the system remains viable. The ability for a system to remain viable is critical if it is to continue to provide required functionality for its stakeholders. Core viability concerns includes the non-functional requirements for understandability, usability, robustness, and survivability. Purposeful design requires an understanding of each of these requirements and how to measure and evaluate each as part of an integrated systems design.
