Project management is the discipline of initiating, planning, executing, controlling, and closing the work of a team to achieve specific goals and meet specific success criteria. Aproject is a temporary endeavor designed to produce a unique product, service or result with a defined beginning and end (usually time-constrained, and often constrained by funding or deliverables) undertaken to meet unique goals and objectives, typically to bring about beneficial change or added value.The temporary nature of projects stands in contrast with business as usual (or operations), which are repetitive, permanent, or semi-permanent functional activities to produce products or services. In practice, themanagement of these two systems is often quite different, and as such requires the development of distinct technical skills and management strategies.
The primary challenge of project management is to achieve all of the project goals and constraints.; these information are usually described in a user or project manual, which is created at the beginning of the development. The primary constraints of many things]. The secondary — and more ambitious — challenge is to optimize theallocation of necessary inputs and integrate them to meet pre-defined objectives
