So first of all, regulations are rarely released by surprise. When a government entity releases a new version of a regulation they generally give a company plenty of advance notice and time to comply. What this means for the project manager is that the upcoming release of new regulations should be discussed early in the project planning process. This should also be included in the project risk management process. Additionally all this information should be communicated to stakeholders. Having open and honest dicussions with the regulatory agencies is also helpful. There should absolutely be no unethical conduct to get around regulations. This is a great way for company executives to end up in jail.
