Which of the following is correct?

Question

Options

• AImpact analysis assesses the effect on the system of a defect found in regression testing.
• BImpact analysis assesses the effect of a new person joining the regression test team.
• CImpact analysis assesses whether or not a defect found in regression testing has been fixed
• DImpact analysis assesses the effect of a change to the system to determine how much

• B
  4% (1)
• C
  9% (2)
• D
  87% (20)

Explanation

Impact analysis is a technique used to evaluate the consequences of a proposed change to a system - specifically, identifying which parts of the system are affected so testers can determine the scope and extent of regression testing required. Option D captures this definition correctly: it assesses the effect of a change to determine how much of the system (and test suite) is impacted.

Why the distractors are wrong:

• A is close but inverts the relationship - impact analysis precedes or guides testing; it doesn't analyze defects discovered during regression testing.
• B is off-topic entirely; adding team members is a resource management concern, not a testing analysis technique.
• C describes confirmation testing (re-testing to verify a fix), not impact analysis.

Memory tip: Think of impact analysis as answering "If we change X, what else breaks?" - it's always about a change driving the analysis, not a defect or a person. If the option mentions a change to the system, that's your signal.
