Strategic Solution Design Questions

Covers the end to end process of diagnosing a business or customer problem and developing one or more viable solutions. Expect to generate multiple approaches with different risk and reward profiles, assess feasibility, implementation timeline, resource requirements, costs, trade offs, and alignment with business objectives. Include planning for execution details such as milestones, dependencies, and risk mitigation. Emphasize clear stakeholder communication and recommendation framing, customer focus, anticipation of implementation challenges, and creation of a coherent proposal that justifies the chosen approach and explains why other options were rejected.
