1 - How do I define the List of Legal Regulatory Contractual and Other Requirements? I read all the articles about it, but I still don't know how to define it. There's also no video tutorial on how to identify these requirements.
Answer: The most common ways to gather this kind of information is by interviewing people involved in the process (e.g., operators, technical staff, process owners, contract managers, legal support, etc.), reading the available documentation, and by doing an Internet search. By applying these three methods you will have a good base for which legal, regulatory and other requirements you must comply.
2 - And what if my organization has several locations in different countries?"
Answer: The methods described are still applicable, but you have to ensure to collect this information also from people living in those countries, not only from someone who made an Internet search, because they generally have a closer and better view of what is relevant and needed in terms of requirements.
