lifecyclerelevant

lifecyclerelevant is an adjective used to describe factors, data, decisions, or requirements that influence or are consequential across the full life cycle of a product, service, system, or process. The term emphasizes that the significance of an element is not confined to a single stage but extends from early design through manufacture, use, maintenance, and end-of-life disposal or recycling.

In sustainability and product development, lifecyclerelevant considerations are identified and prioritized to improve environmental, economic, and social outcomes. The concept is closely related to life cycle assessment (LCA), life cycle costing (LCC), and design for lifecycle thinking, which provide methodologies to evaluate impacts and costs along the cradle-to-grave path.

Assessing lifecyclerelevance involves defining scope, stages, and impact categories, then screening data accordingly. It helps guide decisions such as material selection, durability, energy efficiency, recyclability, maintenance requirements, and data management across stages.

Examples: choosing a polymer with high recyclability is lifecyclerelevant because it affects production, use, and end-of-life; a software architecture decision may be lifecyclerelevant if it impacts long-term maintenance and data portability; in construction, building envelope choices influence energy use over the building's life.

Limitations: the term is context dependent and not universally standardized; what is lifecyclerelevant can vary among stakeholders and regulatory frameworks.
