Abstract:
The productivity of employees is a key driver of organizational success, particularly in the energy sector where competition is intense, and operational efficiency is crucial. The main objective of this study is to examine the effect of manpower development on productivity in NNPC Gas & Power Investment Services (NGPIS) Abuja, Nigeria. A descriptive research design was employed, utilizing a structured questionnaire distributed to 150 employees of NGPIS. Data was analyzed using regression via the Statistical Package for Social Sciences (SPSS). The results indicated that manpower development (employee retention rates, skills assessment and career progression) had positive and significant effect on productivity (efficiency) in NNPC Gas & Power Investment Services. Specifically, skill assessments (SKA = 0.482) had the most significant impact on productivity, followed by career progression (CAP = 0.334) opportunities while retention rate (RER = 0.139) had the least significant effect on employee efficiency. The findings highlight the need for the company to invest more in regular skill evaluations and provide clearer career advancement pathways to improve job satisfaction and organizational performance. The study concluded that effective retention strategies, skills assessment, and career progression opportunities are critical for enhancing employee productivity at NNPC Gas & Power Investment Services. The study recommended that NNPC Gas & Power Investment Services should focus on improving retention strategies, investing in continuous skill assessments, and ensuring that career progression opportunities are clearly communicated and accessible to all employees. These practices will contribute to the long-term success and competitiveness of the organization in the energy sector.

Keywords: Efficiency, Career Progression, Manpower Development, Productivity, Retention Rate, Skills Assessment.
