摘要:The article concerns the impact of stakeholders on project management in non-profit organizations. This issue was presented from the perspective of the organization’s project management maturity. It seems that this issue has not yet been adequately researched by scientists. Contribution was made to the theory of project management by highlighting the need to adjust the level of project management maturity and stakeholder management maturity, and by recommending areas for further research. It has been noted that stakeholder management and risk assessment are just as important as the issues of financing projects and planning their purpose, scope and selection of project teams. The conclusions were based on the analysis of the results of empirical research. The empirical material came from a study based on a sample of 93 non-profit organizations operating in Poland.
