Final answer:
Whether a problem-based approach is the most productive for generating concepts depends on the context; different strategies can be effective in different scenarios. Engineers use both structured and unstructured approaches, including brainstorming, expert information, and gathering customer feedback.
Step-by-step explanation:
The statement regarding the problem-based approach as the most productive concept generating system or technique can be subjective and context-dependent. While problem-based approaches are widely used and can be very effective in generating practical solutions because they are rooted in real-world issues, it is not categorically true that they are the most productive in all cases. There are various techniques for generating concepts and defining problems such as brainstorming, mind searches, design sessions, and idea dumps; each has its own merits and can be more effective in different scenarios.
Engineers often use a structured approach that may blend unstructured and step-by-step methods to explore a wide variety of ideas. Understanding the design problem involves multiple strategies such as finding expert information, identifying the real problem, and gathering customer feedback. Additionally, approaching a problem from multiple directions enhances flexibility and validation of potential solutions.
