Dual Diligence is a method of due diligence which seeks to maximize the efficiency and accuracy of business decisions. It involves assessing every aspect of a potential investment or merger before making a commitment. It takes into account financial, legal, operational, environmental and social aspects, as well as other relevant areas. In order to reduce risk and ensure thoroughness, two separate teams of experts are relied upon to independently assess the viability of an investment. This comprehensive approach allows for informed decision-making and reduces the likelihood of failure.
