What does a life cycle perspective in decision making consider?

• A. Initial design cost only.
• B. Costs and impacts from conception to disposal; integrates sustainability, operability, and long-term value.
• C. Only maintenance costs.
• D. Only energy usage.

Answer: (B)

A life cycle perspective looks at every stage of an asset’s life, from conception and design through construction, operation, maintenance, renewal, and disposal. It considers all costs and impacts across those stages, not just the upfront price, and it aims to optimize total lifecycle cost and performance. This approach integrates sustainability, operability, reliability, and long-term value, recognizing that decisions made early can influence costs and outcomes for decades.

Focusing only on initial design cost misses future expenses and impacts; concentrating solely on maintenance costs ignores the broader lifecycle; and considering only energy usage overlooks other economic and non-economic effects across the asset’s life.
