Explanation: The sequence represents the working steps of a Wideband Delphi technique

A. Two
B. Three
C. Four
D. All of the mentioned

Explanation: Preparation, Execution and Follow up are the three phases to be achieved for a successful brainstorming session.

A. System Analyst
B. Scribe
C. Facilitator
D. Manager

Explanation: A Facilitator (a customer/developer/an outsider) controls the FAST meeting.His role is to ensure that the meeting is productive.

A. It incorporates human element into design
B. SSM is in its infant stage
C. SSM is suitable for new systems
D. Standard methodologies like Role Exploration, Issue Resolution and Reorganization support SSM

Explanation: SSM is still in its infancy.It is evolving and its industrial usage is low.

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.

A. C – Customer
B. A – Actor
C. T – Transformation
D. E – ER Model

Explanation: ‘E’ in CATWOE stands for Environmental constraints.

A. True
B. False

Explanation: QFD involves heavy investment in initial stages, thus bounding the management to provide appropriate funding for the development process .

A. It involves successive steps
B. It involves just one task
C. The prototype is built with the idea that it will eventually be converted into final system
D. It has a shorter development time

Explanation: Except option b all other options represent the characteristics of an evolutionary prototype

A. Portability
B. Maintainability
C. Availability
D. Both Portability and Maintainability

Explanation: Availability is user specific requirement.
