PurposeRapid changes in the business environment and the accelerating dynamics and increasing complexity shaping the functioning of organizations have given rise to modern concepts of people management. The Management 3.0 (M3.0) concept was developed based on agile project management concept; however, it can be implemented not only in projects, but also in the entire organization. It consists of six pillars such as: energizing people, empowering teams, aligning constraints, developing competencies, growing structure, and improving everything. The paper aims to present the relationships between the level of implementation of the above-presented pillars and such variables as the scope of use of agile project management methodologies, and project managers' (PMs) as well as HR practitioners' knowledge in this area.Design/methodology/approachMembers of PMI and IPMA representing 34 companies located in Poland took part in the research which was based on a CAWI method.FindingsResearch shows that the level of M3.0 implementation – in terms of its six pillars – is internally consistent but mostly on a “defined” level. No correlation was observed between the implementation of M3.0 and the frequency with which agile project management methodology is applied. On the other hand, there is a strong correlation between the level of PMs' knowledge and the implementation of some of the M3.0 pillars. HR specialists' knowledge in the field of M3.0 is not associated with organizational advances in the implementation of M3.0.Originality/valueAs the first research project in the area of M3.0, this study proposes practical implications as well as topics which require further empirical exploration.
