Question

Given below are two statements:

Statement I: Cleanroom software process model incorporates statistical quality certification of code increments as they accumulate into a system.

Statement II: Cleanroom software engineering follows the classic analysis, design, code, test, and debug cycle for software development, focusing on defect removal rather than defect injection.

In light of the above statements, choose the correct answer from the options given below:

a) Both Statement I and Statement II are false.
b) Both Statement I and Statement II are true.
c) Statement I is false, but Statement II is true.
d) Statement I is true, but Statement II is false.

Answer 1

The correct answer is option b) Both Statement I and Statement II are true.

Step-by-step explanation:

Both Statement I and Statement II are true about Cleanroom software engineering; Statement I explains the incremental statistical quality certification, while Statement II emphasizes defect prevention over defect correction.

Cleanroom software engineering is a process where a software product is developed with the emphasis on quality and reliability. Statement I accurately describes that the Cleanroom software process model includes statistical quality certification of code increments. As the software is developed, smaller, statistically certified sections of code are integrated into the larger system ensuring that the overall quality of the software system is maintained.

Statement II describes another key principle of Cleanroom software engineering. This model focuses on defect prevention during the software development process, rather than on finding and fixing defects after they are injected into the code. This practice results in a decrease in the overall number of errors, as the process emphasizes rigorous engineering practices that prevent the introduction of defects in the first place.
