Final answer:
The incorrect step in the heuristic approach to problem solving is 'After completing step 1 go to step 2, and so on until the last step in the solution,' as the process does not necessitate sequentially going back to prior steps after step 1.
Step-by-step explanation:
Heuristic Approach in Problem Solving
When solving a problem using a heuristic approach, certain steps are typically followed as part of the strategy. The steps are usually: 1) Understand the problem, 2) Devise a plan, 3) Carry out the plan, and 4) Look Back to evaluate the solution and the process.
The option in the question, "4) After completing step 1 go to step 2, and so on until the last step in the solution" is incorrect. This because the process is not strictly linear and does not necessarily require going back to previous steps sequentially after step 1 is completed.
Heuristic strategies may include practices like mind searches and brainstorming, especially in the understanding and planning phases. Engineers, for example, use a more structured approach during idea dumps and design sessions, to ensure they generate ideas methodically in their design process.
In defining the design problem, a heuristic approach would involve techniques such as finding expert information, trying to identify the real problem, and gathering information from customers to ensure a comprehensive strategy.
