What is the process of judging how well a design meets the specification and identifying areas for improvement?

• A. Evaluation
• B. Fitness for purpose
• C. Product life cycle
• D. Design for recycling

Answer: (A)

Evaluation is the process of judging how well a design meets the specification and spotting areas for improvement. After a design is developed or a prototype is built, engineers compare its performance against the stated requirements, using tests, measurements, and criteria like accuracy, durability, safety, and cost. When gaps or weaknesses are found, the gathered information guides changes and iterative refinements to enhance the design. The other terms describe different ideas: fitness for purpose is about whether the product can do its intended job, product life cycle outlines stages from concept to disposal, and design for recycling focuses on making products easier to recycle.
