How do you measure the success of a technical program once it is launched? Define a balanced KPI framework, explain leading and lagging indicators, and describe how you would set targets, establish baselines, and evaluate trade-offs. Assume access to launch plans, product and operational telemetry, adoption data, incident logs, customer feedback, and stakeholder reports; include the measurements, review cadence, and decision rules you would use.
