This paper explores the significant impact of culture on organizational development and change management.

Various elements were analysed, including organisational culture, individual staff culture, customer culture, leadership styles, and the overall awareness and understanding of the organisational culture within the community context.

To foster a positive relationship between employee and organizational cultures, inclusivity is essential
