If a manager changed quality reports to achieve bonus target which professional principle was broken?

Correct answer: Integrity and honesty

A quality report is expected to present truthful and reliable information about a product or process. Changing it merely to reach a bonus target is deliberate misrepresentation and violates the professional principles of integrity and honesty. Therefore option A is correct. Restricted entry, formal education, and division of work may relate to other organisational or professional ideas, but none addresses the manager’s deliberate falsification of records.

Integrity means remaining truthful even when dishonesty could bring a personal reward. Honesty requires the manager to report quality results accurately, disclose problems, and avoid manipulating evidence. Altering the report can mislead customers, supervisors, investors, or regulators and may expose people to unsafe or poor-quality outcomes. A bonus target does not excuse this conduct; it makes the conflict between personal gain and professional duty clear. Since the manager changed official information for reward, the broken principle is integrity and honesty. Hence option A is the appropriate answer.
