Final answer:
No, the concept with the highest overall score in a decision matrix should not always be selected for the final design. Factors beyond the numerical scores, such as market acceptability and user comfort, must be taken into account. A qualitative assessment is essential in addition to the structured decision process offered by the matrix.
Step-by-step explanation:
The answer to whether the concept with the highest overall score should always be selected for use in the final design is B) No. After creating a decision matrix, the concept with the highest score is a strong contender, but one must also consider factors beyond the numerical scores. The decision matrix helps to structure the thought process and compare different design options against each other based on certain set criteria. However, it is also important to consider the qualitative aspects of each design, including potential market acceptability, user comfort, and other strategic factors.
In the referenced case study, even though Concepts 1 and 5 scored high regarding pollution, renewable energy usage, and cost, they were also the least comfortable for consumers. This suggests that these designs might not be successful commercially. Therefore, the design team must contemplate whether the criteria used were comprehensive and whether customer desires were captured accurately. If not, they might need to revise the criteria or explore different assumptions in the Concept Generation step. It is vital to understand that the decision to proceed with a design is not solely based on a quantitative score but also on qualitative judgment on whether it meets all project constraints and market needs.
