How can firms ensure that their code of business ethics is read, understood, believed, remembered, and acted on rather than ignored?

Answer: The best way to ensure that your company has read and understand the code of ethics is to establish a policy for employees to read it every year and that at the end of the reading, take a knowledge test with a minimum of 90% to pass.

Explanation: The code of ethics establishes parameters that standardize the behavior of people linked to a company. By conducting the assessment every year you ensure that people refresh the code of ethics. You can also offer tutorials that serve to get the message better before the evaluation and if someone fails the evaluation, that person must repeat it until they qualify at this 90%.
