Abstract
The study examined the effect of organizational culture parameters on organizational performance with particular reference to MTN, Nigeria. The study employed a purposive sampling technique to choose MTN, Nigeria, as the research subject, and a simple random sampling method was employed to select 125 respondents from a total population of 3,150 permanent staff members. A structured questionnaire was used to collect data from the respondents. Regression analysis was employed to assess, elucidate, and forecast relationships between the variables. The study established a significant positive association between innovation and risk-taking, attention to detail, outcome orientation, team orientation, aggressiveness culture and organizational performance. This finding underscores the importance of meticulousness in ensuring high-quality service, network reliability, security, and customer satisfaction. It also facilitates compliance, efficiency, and innovation in a competitive telecommunications sector. Subsequently, the study recommended that telecom companies in Nigeria should create a dynamic and adaptive environment that is responsive to customer needs, innovative, and competitive. These cultural attributes can help them navigate the diverse and challenging landscape of the Nigerian telecommunications industry, resulting in higher customer satisfaction, sustained growth, and a strong market presence.
