Value engineering is a systematic approach to providing necessary project functions at the lowest cost. It focuses on functions rather than physical attributes and promotes less expensive alternatives without sacrificing functionality. The standard process involves gathering information, analyzing functions, generating alternative solutions, evaluating options, developing plans, and presenting results. Functions are described using verb-noun pairs, and can be primary functions that cannot be compromised or secondary functions that provide convenience. Value engineering sessions take a step back to consider projects from a functional perspective to potentially innovate and save money compared to standard linear thinking.
