Summary Review of Chapter 7: Quality and Innovation in Product and Process Design
Designing Products for Quality
The process of designing products consider many aspects such as the functions, capabilities, limitations, better options, production cost, and selling price. The Kano Quality/ Design Model identifies exciting quality, performance quality, and basic quality, showing that quality is defined as a function obtaining the requirements of the customer and high satisfaction levels. In the Kano Model it is also analyzed that as time passes, there is an increased demand making the exciting quality turn into a basic expectation.
The Design Process
1 Generation of product idea: This is the initial stage for brainstorming from internal and external sources. External sources are customers, consultants, manufacturers, inventors, experts, etc.
2 Projection of customer’s future needs: The product design should exceed the current needs of the customer with strategic planning with consideration to the future needs of the customer.
3 Feasibility statement of technology: Quality-testing of the product is done to assess performance, limitation, special considerations, etc.
4 Process selection technology development: The process of how the product is transformed from its raw materials to the final output is carefully selected.
5 Definition of final product: This is the finalization of drawings and specifications, as well as the identification of similar products and derivative products.
6 Marketing Plan: The customers, supply chain, and the distribution process are defined. Also, the maintenance, repair, and warranties are designed during this stage.
7 Evaluation of Product: The product design specification (PDS) containing the design, functions, and features of the product is made.
8 Design of manufacturing system: The technology that will be able to produce specific, high-quality products at minimal cost is identified.
9 Manufacture, delivery, and use: This is the stage where the products reach and are enjoyed by the consumer.
Quality Function Deployment (QFD) This approach by Dr. S. Mizuno involves translating the needs of the customer into product design. The “house of quality” is used in this approach, tackling customer requirements and technical elements. With these two categories, the relationship, correlations, and competitive assessment are identified to meet the customer’s requirements.
Technology in Design
The technology used nowadays is called computer-aided design (CAD) system. This is used to help designers with unique and various ideas. An advancement that is found very beneficial to designing is the multi-user CAD systems enabling simultaneous collaboration from different parts of the world. CAD systems can be us...
