Abstract The development of big data technology provides new ideas and choices for the change of enterprise management style, and informationization management innovation becomes an important means to enhance enterprise competitiveness. In this paper, we mainly use the enterprise informatization maturity model, critical success factor method PDCA management cycle, and other methods combined with the Internet big data technology to study the optimization scheme of enterprise informatization management innovation. The evaluation model is used to evaluate the enterprise’s performance after informatization management innovation to assess the effect of enterprise informatization management innovation. Through the case study of Enterprise-A, which is mainly engaged in the manufacture of steel structure parts for new energy power generation equipment, it is concluded that the management structure of Enterprise-A is clearer, and the authority and responsibility of each department are more explicit after the optimization of information management innovation. The optimized collaboration platform system, human resource management information system, and mobile office system have contributed to Enterprise A’s increased competitiveness in the market and industry. The evaluation index system of Enterprise-A, after the optimization of information technology management innovation, is constructed with 1 target layer, 8 criteria layers, and 24 index layers using the topological evaluation model. After calculating the weights and other work, it is concluded that the performance of enterprise A after informationization management innovation reaches grade 4, which is in the state of “good”. The optimization program of Enterprise A’s information management innovation is effective, as evidenced by this.
