What is the difficulty when requirements are unstructured? Does the customer not understand the business?

Unstructured requirements create several key challenges:

• Uncertainty and ambiguity: without a clear structure, it's difficult to understand exactly what needs to be implemented, leading to discrepancies between the team and the customer.
• Difficulties in estimation and planning: it's hard to estimate the scope of work and timelines if requirements are not specified.
• Risk of not meeting expectations: without clear acceptance criteria, there's a high chance that the customer will be dissatisfied.

If the customer does not understand the business, it worsens the situation because they cannot clearly articulate tasks and priorities. In such cases, the analyst should actively engage in clarifying business goals, ask clarifying questions, conduct interviews, and use process modeling techniques to structure requirements and make them understandable.
