“…The Software Engineering Institute (SEI) is considered a pioneer in the field of determining the maturity level, as in the 1980s, it came to the conclusion that the most reliable contractor (executor, supplier) is a counterparty that has a high level of production and managerial maturity [8]. Since then, scientists and project management specialists have developed about 30 different maturity models [9], the most popular of which are OPM3 [10], IPMA DELTA ® [11], PMMMsm [6], P3M3 ® [2], SPICE [12], PM2 [13], PMMM [14][15][16][17] and ProMMM [18,19]. It should be noted that the development of project management maturity models stimulate the creation of a maturity model in terms of risk management, which, with increasing maturity, can eliminate the most dangerous risks [20,21].…”
