Key focus of defect prevention

Which of the following best describes the main goal of defect prevention in software testing?

A To increase the number of test cases executed

B To find and fix defects after the software is released

C To reduce the time spent on testing activities

D To identify and eliminate the root causes of defects before they occur

💡 Hint

Think about stopping problems before they happen, not after.

Defect prevention aims to stop defects from occurring by addressing their root causes early in the development process.

Common defect prevention technique

Which technique is commonly used in defect prevention to reduce errors during software development?

A Automated regression testing

B Code reviews and inspections

C Load testing

D Random exploratory testing

💡 Hint

Think about checking code carefully before it runs.

Code reviews and inspections help find defects early by having peers examine code, preventing defects from progressing further.

Assertion on defect prevention benefits

Which of the following assertions about defect prevention is TRUE?

A Defect prevention reduces the number of defects found during later testing phases.

B Defect prevention eliminates the need for any testing activities.

C Defect prevention delays the delivery of software products.

D Defect prevention increases the overall cost of software development significantly.

💡 Hint

Think about how preventing defects early affects later testing.

By preventing defects early, fewer defects appear in later testing phases, reducing rework and improving quality.

Role of training in defect prevention

How does training and education contribute to defect prevention in software projects?

A It only helps testers find defects faster during testing.

B It replaces the need for formal testing processes.

C It equips developers and testers with skills to avoid introducing defects.

D It increases the number of defects by adding complexity.

💡 Hint

Think about how knowledge affects quality.

Training improves skills and awareness, helping team members avoid mistakes that cause defects.

Defect prevention and process improvement

Which statement best explains the relationship between defect prevention and process improvement?

A Defect prevention is a part of process improvement aimed at reducing defects by improving development processes.

B Process improvement focuses only on speed, while defect prevention focuses only on quality.

C Process improvement and defect prevention are unrelated activities.

D Defect prevention replaces the need for process improvement.

💡 Hint

Consider how improving how work is done affects defects.

Defect prevention is achieved by improving processes to avoid defects, making it a key part of process improvement.
