Marketers must do no harm. This means doing work for which they are appropriately trained or experienced so that they can actively add value to their organizations and customers. It also means adhering to all applicable laws and regulations and embodying high ethical standards in the choices they make.
Marketers must foster trust in the marketing system. This means that products are appropriate for their intended and promoted uses. It requires that marketing communications about goods and services are not intentionally deceptive or misleading. It suggests building relationships that provide for the equitable adjustment and/or redress of customer grievances. It implies striving for good faith and fair dealing so as to contribute toward the efficacy of the exchange process.
Marketers must embrace, communicate and practice the fundamental ethical values that will improve consumer confidence in the integrity of the marketing exchange system. These basic values are intentionally aspirational and include honesty, responsibility, fairness, respect, openness and citizenship.
