A project is a temporary endeavor undertaken to create a unique product, service or result. It has established objectives, a defined life span with a beginning and end, involves several departments and professionals, and is usually doing something that has never been done before with specific time, cost, and performance requirements. A project manager is responsible for planning, scheduling, motivating and controlling the temporary and non-repetitive activities of a project to meet its objectives and ensure its successful completion. Effective modern project management takes an integrative approach to select, prioritize, and implement projects that support organizational strategy and mission.
