The concept of NPI (New Product Introduction)
Differences and connections between NPI (New Product Introduction) projects and R&D projects
NPI (New Product Introduction) must be aimed at outputting products that can be delivered in batches (regardless of batch size), but R&D projects may only output design results. From a certain perspective, NPI (New Product Introduction) serves R&D projects (helps improve design, helps design validated, and helps coordinate the design and manufacturing)
The main obstacles of NPI (New Product Introduction) are frequent design changes and difficulty in obtaining initial product materials, especially since many materials are also part of the new design, but the responsibility for organizing the material often falls to the manufacturer.
NPI (New Product Introduction) requires the manufacturer to respond quickly, to have a high degree of internal and external collaboration, to have the technical ability to move forward, and to organize the business ability of external resources backward. Some companies require NPI (New Product Introduction) to have an engineering background. On the one hand, when developing and designing products with a new process, they should point out mass production difficulties in a timely manner to avoid designing products that cannot be mass-produced, and on the other hand guide manufacturing plants to improve their process capabilities.
NPI (New Product Introduction) project manager is an important position for manufacturers or supply chain companies. NPI (New Product Introduction) engineers are responsible for the success or failure of the entire process from trial production to mass production of new products. The effectiveness of work directly affects the economic benefits of the NPI (New Product Introduction) project.
Three validation stages of NPI (New Product Introduction)
EVT: Engineering Validation Test
The design validation in the early stage of product development is generally an engineering prototype, which is used for debugging and verification by R&D engineers. Many things have just been designed, and there are still many problems so the R&D engineers keep testing feasible design solutions. All possible design problems must be corrected one by one. The R&D engineers focus on completing the design and product specification performance. Generally, R&D engineers conduct comprehensive validation of each function of the engineering prototype.
DVT: Design Validation Test
After solving the problems in the EVT (Engineering Validation Test) stage, test all signal levels and timings, and complete the safety regulations. The focus is on identifying design and manufacturing issues to ensure that all designs are within specification and ready for mass production. —Functional parameters meet requirements and design for manufacturability.
PVT: Production Validation Test
It mainly verifies the stability and consistency of various functions of new products, as well as manufacturing capability verification. The purpose of trial production is to do a lot of pre-production manufacturing process verification, so a certain amount of products must be produced, and all production procedures must comply with the standard procedures of the manufacturing plant. Generally, the new products developed are produced for the suppliers who conduct the PVT (Production Validation Test) stage trial production for them. If the situation is smooth, the new product will be trial-produced once in each verification stage. The derived new product can skip EVT (Engineering Validation Test) or DVT (Design Validation Test) according to the actual situation. There will be more than two trial productions in each verification stage.
The role of NPI in the three stages of validation
In the trial production stage, the NPI (New Product Introduction) team must work hard to find and eliminate problems, so as not to bring design problems and process problems to mass production, and SMT processing should timely feedback on the problems in the manufacturing process to the R&D team so that continuous improvement and perfect DFM design.
LKKER SCM emphasizes more detailed design when the product is first designed and solves problems that may occur in the manufacturing and testing process in advance to the design stage.
NPI (New Product Introduction) must integrate all the supply chain resources, and coordinate the trial production, production scheduling, and follow-up of the trial production process. Most of the trial production schedules are very urgent. Generally speaking, if the whole product is produced, it will be completed in one week or less.
