Portfolio performance reporting should occur at what level of granularity for the executive steering committee?
Executives steer strategy, not delivery detail, so reporting must aggregate to summary-level status on strategic goals and financial health. Component-level or task-level data would obscure portfolio balance and overwhelm the steering committee, breaching the granularity the stem demands.
Why this answer
Executives need summarized, high-level reporting on strategic objectives rather than granular project task data.
