Beyond the Production Line: Quality Control Management as a Lever for Employee Performance in Nigerian Manufacturing Firms

Abstract

This study examines the effects of quality control management (QCM) on employee performance in selected manufacturing firms in Delta State, Nigeria. Specifically, it investigates how conformance to standard, process adaptiveness, and employee competency, the three key dimensions of QCM, shape workforce performance outcomes. A descriptive survey design was adopted, with primary data gathered from 94 usable responses (87.04% return rate) derived from a target population of 332 employees across five manufacturing firms, using the Taro Yamane sampling formula. A structured, Likert-scale questionnaire with a Cronbach alpha reliability coefficient of 0.763 served as the research instrument. Data were analysed using descriptive statistics and multiple regression via EViews 13.0. Findings establish that conformance to standard (β = 0.1734, p = 0.046), process adaptiveness (p = 0.036), and employee competency (β = 0.0346, p = 0.010) each exert a statistically significant positive effect on employee performance. The model explains approximately 99.85% of variance in employee performance (R² = 0.9985; F = 890.53, p < 0.001). These results underscore the strategic imperative of institutionalising robust quality control practices in manufacturing settings. The study recommends sustained training investment, inclusive quality governance, and dedicated quality control units in Delta State manufacturing firms.
