Software Project Management (SPM) is the process of planning, organizing, and overseeing the development and delivery of software projects to ensure they are completed on time, within budget, and meet quality and client requirements. It involves applying specific knowledge, skills, and techniques to coordinate resources, manage scope, mitigate risks, and facilitate communication among stakeholders. SPM is essential because many software projects fail due to poor planning and management, and it provides the structure needed to transform complex, intangible software development processes into successful outcomes.
