Which of the following is NOT one of the six steps in the design process?

• A. Define Problem
• B. Generate Concepts
• C. Develop a Solution
• D. Market Analysis

Answer: (D)

Understanding the design process means focusing on how a problem is defined, explored, and turned into a workable solution. Defining the problem is the starting point, clarifying what needs to be solved and what constraints exist. Generating concepts is the brainstorming phase to create multiple potential approaches. Developing a solution is where one of those ideas is refined into a concrete plan with details and feasibility in mind. Market Analysis, while important for business planning, is not one of the standard engineering design steps. It deals with understanding customers, demand, pricing, and competition—information that informs broader strategy but isn’t itself a step in designing a product. So Market Analysis doesn’t fit into the six design-process steps, making it the correct choice for what doesn’t belong.
