Question

Which of the following is NOT a phase in systems analysis? (Points : 2) Scope definition phase

Implementation analysis phase
Requirements analysis phase
Decision analysis phase
None of the above

Answer 1

Answer: Decision analysis phase

Explanation: System Analysis is the technique for analyzing and studying the components of a particular system .The perspective of system analysis is to find the requirement of every component in the system and the functioning performed by it.

Decision analysis phase is not the part of system analysis because most relevant solution for the system is not being searched. Functional Analysis System Technique(FAST) is the technique in which the decision analysis phase is used to find the best decision.

Other options are incorrect because implementation analysis phase,scope definition phase and requirement analysis are the part of the system analysis cycle.Thus the correct answer to the given question is decision analysis phase.

Answer 2

The phase of decision analysis

Step-by-step explanation:

The system analysis stages, generally incorporate arranging, examination, structure, execution, and upkeep/support. As such, SDLC is a reasonable model that aides venture the executives in data framework advancement.

Decision analysis is not a phase of the system analysis.

In the Functional Analysis System Technique abbreviated as FAST , Decision analysis is the final stage, to locate the best arrangement. Decision tree is one of the tool in decision analysis that uses a tree-like model which includes decision and their outcomes.
