The Effect Of Procedure Compliance On Employee Performance In The Aviation Industry
Abstract
Employee performance is critical in aviation, where reliable task execution, service quality, and adherence to operational standards are essential. This study examined the relationship between procedure compliance and employee performance among employees at Kualanamu airport, Indonesia. A quantitative cross-sectional survey was conducted involving 140 employees drawn from a population of 579. Respondents were selected using proportional stratified random sampling across five organizational units. Both constructs were measured using five questionnaire items on a five-point Likert scale. Data were analyzed using descriptive statistics, Cronbach’s alpha, and simple linear regression in IBM SPSS Statistics. The procedure compliance scale demonstrated high internal consistency (Cronbach’s α = .940), while the employee performance scale showed satisfactory reliability (α = .885). The mean score for procedure compliance was 4.304 (SD = 0.714), compared with 3.266 (SD = 0.794) for employee performance. Regression analysis revealed a positive and statistically significant association between procedure compliance and employee performance (B = 0.675, β = .607, t = 8.969, p < .001). The regression model explained 36.8% of the variance in employee performance (R² = .368; adjusted R² = .364) and was statistically significant, F(1, 138) = 80.446, p < .001. These findings suggest that adherence to established procedures is associated with employees’ reported work performance. The results highlight the relevance of clear operational procedures, employee training, and performance feedback. However, the cross-sectional design does not establish causality. Therefore, the findings should be interpreted as evidence of statistical association, with additional diagnostic analysis and future research using objective performance indicators recommended to strengthen the conclusions.
