The impact of employees’ attributes on the quality of food products

Abstract

Purpose

The purpose of this paper is to analyse the importance of specific, quality-related employees’ attributes to the enhancement of product quality in food companies. The main goal is to examine the synergistic relationships between specific employees’ attributes, which have been related in literature to ISO 9000 successful implementation, to continuous improvement, operational performance and product quality.

Design/methodology/approach

The analysis includes an initial exploratory factor analysis, followed by confirmatory factor analysis and structural equation modelling, in order to investigate the relations between the constructs of the proposed model.

Findings

The findings reveal that although the examined quality-related “employees’ attributes” do not directly contribute to “product quality”, they influence both “continuous improvement” and “operational performance” of food firms. The results also confirm the impact of both “continuous improvement” and “operational performance” on “product quality” and also that “continuous improvement” helps explain “operational performance”.

Research limitations/implications

The domain in which the model has been validated, the restricted use of moderators in the model and lack of empirical validation of the model in non-food sector companies, based on various respondents from each company, are a number of limitations associated with this study which suggest future research proposals.

Practical implications

The findings of this study can motivate managers of food companies to focus on certain quality-related employees’ attributes in order to boost continuous improvement of ISO 9001 systems and operational performance of their companies, leading to product quality enhancement.

Originality/value

This study finds particular relevance in emphasizing that although specific quality-related employees’ attributes, as these are detected in literature, have a significant contribution towards continuous improvement and operational performance, they are not the only critical factor leading to product quality. More complex relationships need to be considered by integrating other constructs as major antecedents of food product quality.
