Final answer:
The quality of a system, as described, revolves around its integrity and secure performance, which requires a mixture of engineering knowledge and expertise in systems design, security, and technology.
Step-by-step explanation:
The quality that a system has when it performs its intended function in an unimpaired manner, free from unauthorized manipulation of the system, refers to its integrity and usability in a reliable and secure context. This concept encompasses the ability to apply knowledge of mathematics, science, and engineering to ensure the system operates correctly. Moreover, it involves the ability to design and conduct experiments, as well as to analyze and interpret data to maintain the system's integrity and performance. The definition from NIST SP 800-27 Rev. A implies a focus on the security aspect of systems, reflecting principles of computer security and technology.
Understanding system design also requires familiarity with various constraints including economic, environmental, social, political, ethical, health and safety, manufacturability, and sustainability. These constraints guide the design process to meet desired needs and ensure the system functions as intended within the specified limitations.
In engineering terms, the quality of a system can be quantified by measures such as angular frequency and its stability within an isolated system, where external forces do not affect its operation. Thus, the knowledge and expertise in engineering and technology disciplines are crucial to maintaining the quality of systems.
