What's the difference between a product manager and a project manager?
Model answer
Model answerA project manager ensures things are delivered on time and to spec. A product manager decides what should be built and why. The confusion is common because both use roadmaps and run meetings — but the core job is different. PMs own the problem space; project managers own the execution process. A PM who only manages timelines and stakeholders is doing project management. The PM's unique value is bringing user insight, business context, and product judgment to decide what problem to solve next.
