Organizational values are established to have employees work in unison to achieve the company's common goals. It is one of the management strategies to achieve organizational success. Considering its importance, organizations need to understand the effect of organizational values on their performance. This study aims to assess the effect of organizational values (OV) on organizational effectiveness (OE) and to create an intervention program that helps drive employees to imbibe the values and improve the extent of their application in decision-making, behavior, and actions. The researcher employed quantitative research methods to collect primary data using the total elimination method from XYZ company in the Philippines, with 64 full-time employees from different departments in the head office, where 39 valid responses were obtained. Organizational values were further classified into business, relational, development, and contribution values. The hypotheses were tested using multiple linear regression and the results identified the effect of OV on the factors of OE. It was concluded that OV, as a whole, has a significant effect on OE. Thus, the more the employees apply all of the organizational values, the better their business performance will be. Furthermore, the action plan presented promotes and reinforces the application of the organization’s core values.
