Software Dependability:
Software dependability is a measure of software’s availability, reliability, and its maintainability, and maintenance support performance and characteristics such as durability, safety and security.
Expert Solution & Answer
Explanation of Solution
Importance of software dependability:
Software dependability is a measure of software’s availability, reliability, and its maintainability, and maintenance support performance and characteristics such as durability, safety and security.
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.
Software dependability is most important in socio-technical system because of the following reasons:
- Unreliable software is liable to be discarded by users: Users May not use the system if they don't trust it.
- System failure costs may be enormous: System failure may lead to a loss of business.
- Unreliable systems may cause information loss: An undependable system may damage its external environment.
- An undependable system may lose or damage valuable data.
- Unreliable systems are difficult to improve: The reputation of the company who produced the system may suffer.
- Inefficiency is predictable: Software that is unreliable can have hidden errors which can violate system and user data without warning and whose consequences are not immediately obvious and the system may be in a breach of laws of consumer protection.
