Quality Engineering

Step 1: Analyze the core concept in the definition. Step 1: The definition focuses on achieving required "functions" at a "minimum cost" while maintaining "quality" and "reliability." This ratio of function to cost is the classic definition of "value."
Step 2: Define Value Engineering.
Step 2: Value Engineering (also known as Value Analysis) is a systematic method to improve the value of products, services, or processes. It does this by analyzing the functions and seeking to achieve those functions at the lowest possible life-cycle cost without sacrificing performance or quality.
Step 3: Match the definition to the term.
Step 3: The provided definition is a textbook description of Value Engineering. The other terms are too general or do not fit the specific methodology described.
