Which is better, PM or PMO?

Neither is "better" — a PM (project manager) and a PMO (project management office) do different, complementary jobs. A PM owns one project end to end: scope, schedule, budget, and delivery. A PMO sits above individual projects, setting standards, governance, and reporting across all of them, and supporting PMs with tools and training. If you run one or two projects at a time, a strong PM is enough. If you juggle many projects across teams or locations, a PMO keeps them consistent and aligned with strategy. Either way, both drown without good tooling — AgentUI gives PMs and PMOs the same live, role-based view of operations, so status reports build themselves instead of eating hours every week.
