# Perform a life-cycle cost analysis.

## Definition

Performance should include the costs of a system or a component over its entire life span. Typical costs for a system may include- acquisition costs (or design and development costs)
- transportation costs
- operating costs, such as
- cost of failures
- cost of repairs
- cost for spares
- downtime costs
- loss of production

- disposal costs.

## Process/Skill Questions

- What are the considerations of true cost to include in a life-cycle cost analysis?
- What is a life-cycle cost analysis, and how can it inform consumer decision making?
- At what point during the cycle is system or product most expensive?
- Does the initial price of an object affect the life-cycle price?
- On what elements of a product’s cost do consumers traditionally focus? What elements of a product's cost do consumers traditionally ignore?
