The paper discusses the importance of maturity models in IT management, which have become essential tools for assessing and improving organizational capabilities. Over a hundred maturity models have been developed, but their development processes are often poorly documented. The authors propose a scientific approach to develop criteria for creating maturity models, which are then used to compare and consolidate these models into a general procedure model. This model serves as a manual for designing and evaluating maturity models methodically. The paper includes a case study on the development of the IT Performance Measurement Maturity Model (ITPM), which aims to enhance Business Intelligence (BI) applications for IT management. The ITPM was designed through an iterative process, combining elements from existing models and tailored to the specific needs of IT performance measurement. The authors emphasize the need for well-documented and methodologically sound development processes to ensure the effectiveness and reliability of maturity models.The paper discusses the importance of maturity models in IT management, which have become essential tools for assessing and improving organizational capabilities.
