Explain 'Who' and 'Why' in problem scoping.

Who: The "Who" block helps identify the people who are directly or indirectly affected by the problem. These people are called stakeholders, who are involved in the problem and will benefit from the solution.

Why: The "Why" block helps us think about why the given problem is worth solving and how the solution would benefit the stakeholders as well as society, such as by improving quality of life, increasing efficiency, or enhancing safety.
