A strong product starts with a specific problem, not a long feature list. Before committing to a build, describe who experiences the problem, when it happens, and what they do today.
Talk to the people doing the work
Ask for concrete examples. Watch the current workflow where possible. The gap between what people say and what they actually need is often where the most useful opportunities appear.
Make the first version focused
Choose one meaningful outcome. Define how you will know the product helps, and keep the first release small enough to learn from. A focused launch gives you better evidence for the next investment.
