Summary

TLDRIn this video, Denmark discusses the concept selection phase in product design and development. The focus is on evaluating multiple concepts based on customer needs and additional criteria. Using a decision matrix, the process compares the strengths and weaknesses of each concept against a reference product. The highest-scoring concept, based on cleanliness values, is chosen for further development. The video also covers the creation of concept sketches and the assessment of secondary needs to determine primary need weights, ultimately leading to the selection of the most promising product concept.

Takeaways

  • 😀 The session is a continuation of a course on product design and development, focusing on the sixth topic of concept selection.
  • 🧐 The process of concept selection involves evaluating numerous alternatives based on customer needs and additional criteria.
  • 📊 A decision matrix is used for concept selection, prioritizing criteria such as comfort, ease of maintenance, durability, price, and functional design.
  • 👟 Two shoe experts and a researcher are involved in the concept selection process, using a plus/minus system to rate concepts against a reference product.
  • 📈 The reference product used for comparison is the 'Everbest' brand, chosen for its shape and comfort as per a previous study.
  • 📝 Each concept is evaluated based on how it compares to the reference product in terms of comfort, maintenance, durability, price, and design.
  • 📊 A clean value calculation is performed for each concept, summing positive, zero, and negative scores to determine the most promising concepts.
  • 📈 The concepts are ranked based on their clean values, with the highest values indicating the most favorable concepts for development.
  • 🎹 Sketches are created for the selected concepts to provide a visual representation for development teams and respondents.
  • 📊 Secondary needs are weighted to determine the primary needs' weights, which are then used to calculate the weighted scores for each concept.
  • 🏆 The concept with the highest total weighted score is selected for further development, moving on to the next stages of testing or production.

Q & A

  • What is the main focus of the lecture?

    -The main focus of the lecture is the concept selection process in product design and development, specifically how to evaluate and choose the best product concept based on customer needs and other criteria.

  • What is the first step after generating product concepts?

    -After generating product concepts, the next step is to evaluate and select the best concept. This is done by comparing the strengths and weaknesses of each concept relative to a reference product or other concepts.

  • What criteria are used in the concept selection process?

    -The criteria used in the concept selection process include customer needs (referred to as primary needs), as well as other factors like comfort, ease of maintenance, durability, price, and functional design.

  • How is the comparison between concepts made?

    -Concepts are compared using a decision matrix where strengths are marked with a plus (+), weaknesses with a minus (-), and if the concept performs the same as the reference product, it is marked with a zero (0).

  • What is the reference product used in the example, and why?

    -In the example, the reference product used is an 'Everbest' brand shoe, chosen because it is considered the best based on shape and comfort. All other concepts are compared against this reference product.

  • How are the concept scores calculated?

    -Concept scores are calculated by summing the positive, negative, and neutral evaluations for each concept. The concept with the highest net score is selected for further development.

  • What happens to the concepts with the highest scores?

    -The concepts with the highest scores, such as concepts C, D, and S in this example, are further developed. This includes creating detailed sketches to provide a clearer idea of the product design.

  • What role do secondary needs play in the selection process?

    -Secondary needs are used to explain the primary needs and are given weight during the concept scoring process. These secondary needs are averaged to obtain the weight for each primary need.

  • How are the final scores for each concept determined?

    -Final scores for each concept are determined by multiplying the score for each criterion (given by experts) by its corresponding weight. The total weighted score is used to rank the concepts.

  • What is the outcome for the concept with the highest total score?

    -The concept with the highest total score is selected for further development, such as testing or production. In the example, concept D has the highest score and is chosen for the next phase.
