Stages refer to distinct phases or steps in a process, often characterized by specific features or activities. For example, in a project management context, stages can include initiation, planning, execution, monitoring, and closure. Each stage has its own objectives and tasks that contribute to the overall success of the project. In the context of human development, stages describe the various periods of growth and change individuals experience throughout their lives. These stages, such as infancy, childhood, adolescence, and adulthood, are marked by physical, emotional, and cognitive developments that shape a person's identity and abilities.
