Which of the following is NOT a step commonly found in the engineering design process?

The engineering design process typically involves a series of steps that guide engineers from identifying a need to developing a solution. The common steps in this process include defining the problem, conducting research to understand the context and requirements, developing concepts, creating prototypes, and testing those prototypes to refine the solution.

The option that is not a standard step of the engineering design process is market analysis. While understanding market needs can be important for the overall success of a project, it is not inherently a part of the design process itself. The focus of the engineering design process is primarily on solving the technical aspects of a problem rather than analyzing the market's response to a product. Market analysis often comes into play after the solution is developed and is typically part of product development or business strategy rather than the design process itself.

In short, market analysis can inform decision-making and guide how a product might be positioned, but it is distinct from the technical iterative steps involved in designing and testing a solution.
