A. i, iii, ii, iv, v, vi
B. iii, i, ii, iv, v, vi

Choose the disadvantage of using SSM as an elicitation technique ?

by
Choose the disadvantage of using SSM as an elicitation technique ?

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.

Which of the following Requirement Elicitation Techniques is applicable to messy, changing and ill-defined problem situations ?

by
Which of the following Requirement Elicitation Techniques is applicable to messy, changing and ill-defined problem situations ?

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.

Keeping the requirements of QFD in mind which of the following is not an example of an Expected Requirement ?

by
Keeg the requirements of QFD in mind which of the following is not an example of an Expected Requirement ?

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.

To ensure that a given root definition is rigorous and comprehensive, The Lancaster team proposed several criteria that are summarized in the mnemonic CATWOE in Soft Systems Methodology (SSM).Which of the following alphabet is representing an entirely different meaning to SSM ?

by
To ensure that a given root definition is rigorous and comprehensive, The Lancaster team proposed several criteria that are summarized in the mnemonic CATWOE in Soft Systems Methodology (SSM).Which of the following alphabet is representing an entirely different meaning to SSM ?

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

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

How is throwaway prototype different from evolutionary prototype ?

by
How is throwaway prototype different from evolutionary prototype ?

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
