Your leadership team should start with a list of problems that have already happened, or problems that nearly happened ("near-misses"), or problems that happened to someone else but could happen to you. You should add to the list the events or issues that potentially threaten your product quality or your business, that keep you awake at night. If you can elaborate what answers you are looking for, the user community here is very helpful.
The greatest value of the Risk Identification exercise is to recognize new Risks which are valid concerns which have not happened yet or the idea hasn't occurred to anyone. There are tools and frameworks for brainstorming risks, you could buy a book or browse the Internet for ideas, look up
FMEA for example. For example, list all the important functions which must occur for your product or business to be successful, then think of scenarios where any one of those functions fail. If you take raw material delivery as an example function, a crucial shipment could arrive late, or a partial shipment, the material arrives damaged, or not what you ordered. The shipment arriving early could also be a problem, if these are perishable items and you have no place to store them. Once you identify Risks, you would prioritize the list, and think of countermeasures or contingencies to reduce the greatest risk items. But you only asked how to
identify risks and opportunities.
A similar thought process could generate a list of potential Opportunities, and you would devise action plans to capitalize on opportunities or put your company in position to increase your benefit.
