What time period does lifecycle of a system span?

The lifecycle of a system typically spans from the initial concept and planning stages through to the design, development, implementation, maintenance, and eventual retirement or decommissioning of the system. This period can vary significantly depending on the type of system and its complexity, often lasting several years to decades. Key phases include requirements gathering, system design, testing, deployment, and ongoing support. Ultimately, the lifecycle concludes when the system is no longer viable or needed, leading to its replacement or disposal.
