servicelife

Servicelife is the period during which a product, system, or service remains capable of delivering its intended functionality under defined conditions. It typically starts at commissioning or deployment and ends when performance, safety, or regulatory requirements are no longer met, or when the owner no longer supports or maintains it. Servicelife is distinct from shelf life, warranty, and total physical lifespan: shelf life concerns storage stability, warranty covers a contractual defect period, and lifespan may include non-operational time; servicelife focuses on operational viability.

Several factors influence servicelife, including design quality, materials and components, manufacturing tolerances, maintenance practices, operating environment, usage intensity, software compatibility, and external dependencies. Estimation of servicelife uses reliability and life data analysis, such as mean time between failures, failure-rate models, wear-out patterns, accelerated life testing, and field feedback. In software and services, servicelife may be tied to end-of-support dates, version lifecycles, and API deprecation.

Organizations define servicelife criteria to balance performance with risk, cost, and regulatory compliance. Maintenance, upgrades, and refurbishments can extend servicelife, while deterioration in performance or safety limits may trigger replacement. From an economic and sustainability perspective, servicelife informs depreciation, total cost of ownership, and decisions about recycling, remanufacturing, or disposal.

Examples include consumer electronics designed for a service life of several years under normal use, aircraft components with fatigue-based limits, and cloud services with defined support and update lifecycles. See also durability, warranty, depreciation, lifecycle assessment, end-of-life.
