‘That discussion starts with a very concise and useful distinction between project management (the world the government knows) and product management (the world it doesn’t). Project management, they write, is “focused on managing to a plan” – such as managing schedule, budget, risk, policy compliance and then reporting status to stakeholders. “Success for a project manager is delivering a defined scope of work on-time and on-budget,” Johnston and O’Connor note. Product management, meanwhile, “is focused on delivering a product a user wants or needs.” Success for a product manager “is delivering a product that users love — and use to complete tasks (or in the private sector — a product customers will pay for).”’
