Due Diligence Review Checklists are a comprehensive set of detailed processes and procedures used in business to ensure that important tasks, such as compliance with regulations, prevention of legal risks, management of financial data, and avoidance of operational losses, are completed successfully. A series of checklists should be established to cover all relevant areas of the business. At each stage of the review process different questions should be asked to evaluate the status, risk and outcome of a task or project. By conducting regular due diligence reviews throughout the year, a business can identify and avoid potential problems before they have a chance to cause damage to operations or reputation.
