Expert Solution & Answer
Chapter 10, Problem 10.3E
Explanation of Solution
Dependable Systems and Socio-technical systems:
Dependable system is the system in which the software is developed using dependable process to reduce errors and avoid failure.
A complex organization design that recognizes the interaction between technology and people and is not limited only to software is known as socio-technical system.
It is important when developing dependable systems to consider these as socio-technical systems and not simply as technical software and hardware systems because:
- A socio-technical system considers requirements spanning hardware, software, personal, and community aspects and applies an understanding of the social structures, roles and rights to inform the design of systems that involve communities of people and technology and it is a dependable process and also reduces errors and avoid failure...
