The lifecycle of development refers to the series of stages that a product or project goes through from conception to completion. This process typically includes phases such as planning, design, implementation, testing, and deployment. Each stage is crucial for ensuring that the final product meets the desired requirements and quality standards. In software development, for example, the lifecycle often follows models like Waterfall or Agile. These models provide structured approaches to manage tasks and timelines, allowing teams to adapt to changes and improve efficiency. Understanding the lifecycle helps organizations deliver successful projects on time and within budget.
