A survey on the maturity state of Iranian grade one construction companies utillzing OPM3 maturity model

The OPM3 self-assessment questionnaire is utilized in this paper first to evaluate maturity state of the large sized construction companies in Iran based on a survey of 81 companies out of 326 which hold a grade one certificate. The main acquisitions of the research are as follows: although all companies having a grade one license are authorized to perform projects of the same size and complexity which practically they do, but definitely they are not in the same level in terms of organizational project management maturity. The data reflected that companies are in reasonable condition in the standardize stage, but they have to put in a lot of effort to improve their situation in other stages mentioned in OPM3. In addition, the band scores achieved by this test are related to some of companies' success factors. The results showed some 59% of Iranian largest companies have a maturity degree less than 50%. Also, no remarkable consistency between the company's maturity degree extracted from OPM3 questionnaire and its historical precedence was observed. Above all, it was conceded that only companies which demonstrate noticeable maturity levels have been able to win the tenders of international projects.
