Unstructured requirements should be organized, validated, and prioritized collaboratively with the customer before solution design begins. Preparing a requirements template and working through each item with stakeholders creates a controlled mechanism for determining business value, urgency, dependencies, feasibility, scope, and priority.
Salesforce's Business Analyst guidance specifically identifies the need to verify and prioritize existing requirements, identify new requirements, and manage them in a controlled repository. Salesforce project-management guidance likewise emphasizes that project teams help stakeholders clarify requirements and classify what represents essential needs versus lower-priority wants or expectations.
Creating a Solution Design Document at this point would be premature. The technical design should be derived from validated business requirements, not from an unprioritized collection of requests.
Option C improves the structure of the requirements but incorrectly places the consultant in a position of evaluating business impact and value independently before discussing them with the client. Prioritization must involve business stakeholders because they own the business outcomes, constraints, and relative importance of the requirements.
The collaborative approach in option A therefore provides the correct transition from raw requirements into an agreed project scope and subsequent design activity.
