This research used quantitative and qualitative methodologies to investigate how working professionals are impacted and account for workplace cultural differences. This paper also sought to make a case for additional quantitative and qualitative research into what shapes and maintains culture by looking at leadership's knowledge of their organization's way of doing things and the impact these multiple knowledge areas have on performance. The literature review section analyzed performance improvement models, the effect of leadership, the behavior engineering model (BEM) and related models, organization culture, and performance. This work also outlined the methodology utilized in studying and reviewing culture and performance. This research aimed to determine a better understanding and increase the use of performance improvement and cultural models to aid organizations in achieving their missions.

Likewise, it can help to create …
