Objectives:
1. identification of the core of the title process and its comparison with known types of patterns of improving management, 2. elaboration on the proposals and topics that enrich knowledge about the processes of HRM improvement, including the problem of institutional isomorphism.

Material and methods:
Literature studies allowed us to identify patterns of organizational improvement change. The subject of empirical research was the content of Polish-language offers posted on websites for consulting companies improving Human Resources Management. The analysis was conducted based on content analysis guidelines. The obtained analysis results were compared with theoretical patterns of changes. In this way, the features of the examined core were identified.

Results:
The identified core of dissemination consists of four phases and three processes with different logic. The interaction of processes can create inconsistency in the entire solution. The dominance of behaviors securing and facilitating HRM operations over other types of managerial behaviors was found. There are no methods of dealing with this asymmetry in the offers.

Conclusions:
The inconsistencies between the core processes of pattern dissemination should encourage practitioners to determine their level of acceptance of the heterogeneity of patterns. For this, it is necessary to develop practical competencies in managing contradictions. Future research should provide a more complete understanding of the specificity of different sources of patterns, the nature of operations performed on patterns, and the identification of inconsistencies in the processes of pattern dissemination. It is also valuable to draw attention to the specific forces of institutional isomorphism that shape the similarity of patterns and ways of disseminating them
