A. Quality Function Deployment (QFD)
B. Prototyg
C. Soft Systems Methodology (SSM)
D. Controlled Requirements Expression (CORE)
Explanation: Soft systems methodology (SSM) is a systemic approach for tackling real-world problematic situations.It is a common misunderstanding that SSM is a methodology for dealing solely with ‘soft problems’ (problems which involve psychological, social, and cultural elements). SSM does not differentiate between ‘soft’ and ‘hard’ problems, it merely provides a different way of dealing with situations perceived as problematic.
A. Ease of software installation
B. Overall operational correctness and reliability
C. Specific system functions
D. Quality graphical display
Explanation: Expected requirements are so fundamental that a customer does not explicitly state them.System functions comes under the category of Normal requirements in QFD which is compulsory to be defined,hence is not an expected requirement.
