Project management involves planning, organizing, and controlling project resources to meet goals and expectations. It applies knowledge, skills, tools, and techniques across project activities. Key aspects of project management include planning, organization, objectives, policies, the project life cycle, control, and human factors. The project life cycle has four phases - initiation, planning, implementation, and closure. Planning defines tasks and assigns resources, implementation performs the outlined work, and closure hands over the final deliverable and identifies lessons learned. Control involves regularly comparing performance to targets and taking corrective actions when needed.
