Effect of leadership and quality culture on quality management practices and operational performance of construction companies in Oman

Purpose Construction companies play a vital role in the development of any country. The objective of the study is to evaluate the influence of leadership and quality culture (QC) on quality management (QM) practices and operational performance (OP). Design/methodology/approach The questionnaire method was used to collect raw data from 325 construction companies in Oman. Confirmatory factor analysis was applied to evaluate the measurement, model reliability and validity. The relationship between the latent constructs was investigated by Partial Least Square - Structural Equation Modeling (PLS-SEM). Findings The findings indicate that, leadership significantly affected QM practices and OP. Moreover, while the QC has significantly influenced QM practices, QC had not influenced OP. One reason is the lack of knowledge of the employee that the quality procedures have the power to reduce rework, waste, and decrease the project's period. And the study found that the QM practices have significantly influenced OP. Research limitations/implications The limitation of this research is that some construction companies have no quality assurance leaders in the project; therefore, the questionnaires were circulated to project managers or project management leaders and that negatively affect the quality of data collecting from the responses. Eventually, the framework is considered to be the main contribution and is recommended for usage in the project. This study gives guidelines for leadership and leadership's accountabilities to provide a keen decision that to improve OP and to ensure the competence of employees. Originality/value The limitation of this research is that some construction companies have no quality assurance leaders in the project and so the questionnaires were circulated to project managers or project management leaders, which could influence the value of the responses. Eventually, the framework appeared to be the main contribution to awareness and is recommended for use to ensure a successful construction project in both the public and private sectors. The current study lays out some relevant roles for leadership and its accountabilities to provide a keen decision to improve OP and to ensure the competence of employees.
