What is the general process of product design and development?

The product design process consists of four stages: development and product planning, detailed design, small-scale production, and incremental production.

1. At the stage of concept development and product planning, integrate information about market opportunities, competitiveness, technical feasibility, and production needs to determine the framework of the new product. This includes the conceptual design of new products, target markets, level of expected performance, investment requirements and financial impact. Before deciding whether a new product is developed, companies can also use small-scale experiments to verify concepts and opinions. Experiments can include sample production and soliciting opinions from potential customers.

 2. The detailed design stage, once the plan is passed, the new product project will be transferred to the detailed design stage. The basic activities at this stage are the design and construction of product prototypes and the development of tools and equipment used in commercial production. The core of detailed product engineering is the "design-build-test" cycle. The required products and processes must be conceptually defined and reflected in the prototype of the product, and then the simulated use of the product should be tested. If the prototype does not reflect the expected performance characteristics, the engineer should seek design improvements to make up for this difference and repeat the "design-build-test" cycle. The end of the detailed product engineering phase is marked by the final design of the product meeting the specified technical requirements and signing approval.

3. The stage of small-scale production. In this stage, the single parts processed and tested on the production equipment have been assembled together and tested in the factory as a system. In small-scale production, a certain number of products should be produced, and the ability of new or improved production processes to cope with commercial production should also be tested. It is at this moment in the product development process that the entire system (design, detailed design, tools and equipment, parts, assembly sequence, production supervision, operators, technicians) is combined.

 4. The final stage of development is incremental production. In incremental production, production starts at a relatively low quantity level; when the organization's confidence in its own (and suppliers') continuous production capacity and ability to market products increases, output begins to increase.
