Research method is based on in-depth empirical qualitative analysis, results are subject of quantitative verification using statistical methods which allows reaching better results. Research proceeds inductively, it means that new knowledge is generated as outcome and matched to theories. Decisions are examined as responses towards business environment components, correlations and significances between active or passive managers’ behavior are demonstrated. Proactive managerial approach is characterized by frequent change and diversification in suppliers, customers, human resources and product portfolio. As a conclusion, managerial response can be interpreted as a product of managers’ activity, personal preferences and abilities. The re-orientation towards recognition of active or passive behavior is developed and matched towards current theories. It can be assumed, that the current scientific discussion is potentially relevant in seeking to explain the role of individual manager.
