ISTQB Certified Tester Advanced Level – Test Analyst (CTAL-TA) — Question 3

A major upgrade of business software has been undertaken, with many new facilities added in response to the wishes of the (internal company) staff. There are now very different screens presented to users, depending on their roles within the business. Due to the nature of the business, computational accuracy is regarded as the area of greatest business risk.
Which of the following quality characteristics would you focus on the MOST when testing the system?

Answer options

• A. Functional correctness.
• B. Functional appropriateness.
• C. Installability.
• D. Functional completeness.

Correct answer: A

Explanation

The correct answer, Functional correctness, is crucial because it ensures that the software performs its intended functions accurately, which is vital given the high risk associated with computational accuracy in the business. The other options, while important, do not directly address the need for precise functionality, which is the primary concern in this scenario.
