As we know from many publications, it is worth using Lean Management in modern enterprises. On the other hand, as scientists and practitioners emphasise, developing an appropriate organisational culture is necessary to obtain the proper results as part of Lean Management. Therefore, in parallel with the organisational changes related to implementing the Lean concept in the enterprise, various activities should be carried out to change the organisational culture into a culture favourable to Lean. There are many studies on how to change an organisation's culture, although it takes much work. Also, many publication threads in the recent period concern the features of the Lean organisational culture (the culture of a lean organisation) or the potential ways of creating this culture. However, knowledge on this subject still needs to be improved, especially from the point of view of management practice. Therefore, the main purpose of this article is to present basic information on the ways of shaping Lean organizational cultures in enterprises in Poland, with particular emphasis on manufacturing companies, based on literature studies and the results of empirical research carried out as part of the doctoral dissertation of one of the authors. The survey was conducted in 2022, using the CAWI method, on a sample of 55 companies. The presented results can be a valuable contribution to understanding the phenomenon of creating a Lean culture in enterprises in Poland. They can be also the basis for further research or analysis in this area.
