To be able to compete, corporations need to manage the complexity and uncertainty in the market environment by improving management. To date, few studies are available to verify the items required for business, particularly banking as a guide for designing such complexities. In this regard, this study seeks to provide validity items that are useful for the world of corporate banking, in managing the complexities of the external environment and in formulating and implementing strategies. By combining the concept of human resource management, socio-economic factors through a dimensional measurement with a stakeholder approach, the study findings demonstrate several important keys for banks to manage external elements and strategies as a guide to measuring effectiveness that can be used as a basis for further studies.
