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.

Evaluate building a custom ML inference platform versus using a managed provider to serve low-latency predictions at 100k QPS. Propose architectures for each option, discuss scaling strategies (autoscaling, batching, sharding), caching, hardware choices (GPU vs CPU), cost-per-inference estimation, and maintenance/operational trade-offs.

Explain how you would estimate compute, storage, and networking resources for a new service expected to reach 10,000 daily active users in year one. Describe the data sources you would use (benchmarks, historical analogs), assumptions to document, safety margins, and how you would validate and iterate on the estimates after launch.

An enterprise asks you to modernize a large monolithic application into microservices to reduce deployment time from days to hours. Outline a 12-month migration strategy covering phases (strangler pattern, API stabilization), data partitioning, CI/CD changes, team organization, risk mitigation, rollbacks, and how you would measure progress with milestones.

Draft a risk register template for a 9-month implementation of a customer portal. Include risk categories (technical, operational, legal, market), likelihood-impact scoring, mitigation actions, owners, trigger conditions, and escalation path. Describe how you would keep this register current during delivery.
