Research on the Maturity Evaluation Model of Reliability Engineering Capability

Reliability engineering capability mainly refers to a level of measurement in which product development enterprises integrate reliability engineering theory and technology into the entire life process of product development, production, and after-sales through a series of engineering practice activities, so as to form or achieve a certain level of reliability. It is closely related to the organizational structure, personnel literacy, management ability, and technical level of product development enterprises. This study comprehensively evaluates the advantages and disadvantages of various aspects, and proposes an innovative Reliability Capability Maturity Model Integration (CMMI) maturity evaluation system for electronic product development enterprises, based on typical product development engineering practice experience. This system establishes a reliability engineering capability evaluation model based on the work required for the entire process of electronic product development. The evaluation is divided into four dimensions, namely organizational capability, management capability, technical capability, and support capability. Each dimension is divided into several sub dimensions, which subdivide the specific evaluation process, totaling 29 processes. Develop corresponding evaluation terms for each process to conduct evaluations. In this model, the maturity level of reliability engineering capability is divided into five levels, namely initial disorder level, basic execution level, comprehensive management level, quantitative management level, and excellence level. In the specific evaluation implementation, the corresponding process maturity level is first given based on the content of the evaluation terms, and then the domain level is calculated based on the weight coefficient of the process, finally obtaining the maturity level of each dimension and the overall reliability engineering capability of the enterprise. On the basis of building an evaluation model, this study provides an application example of reliability engineering capability maturity evaluation. In engineering practice, self-evaluation can be carried out for evaluation items with low maturity, and targeted reliability improvement work can be carried out to achieve the overall improvement of enterprise reliability engineering capabilities.
