Purpose
The purpose of this paper is to identify the influence exerted by a quality management system (QMS) under ISO 9001: 2015 on the quality of public services organizations in Mexico.
Design/methodology/approach
The methodological design was quantitative, explanatory, observational and transversal, for which a sample of 461 public servants from the state of Guanajuato, Mexico was obtained. To test the hypotheses, a structural equation model (SEM) was developed through the statistical software Amos v.21. For the analysis of the data, software SPSS v.21 was used. Regarding the goodness and adjustment indices of the SEM (χ2 = 720.09, df = 320, CFI = 0.933, TLI = 0.926 and RMSEA = 0.05) which, therefore, proved to be acceptable.
Findings
According to the results obtained through the SEM model, the QMS under ISO 9001: 2015 is positively and significantly influenced tangible aspects (β1 = 0.79, p < 0.01), reliability (β2 = 0.90, p < 0.01), related to response quality (β3 = 0.93, p < 0.01), guarantees (β4 = 0.91, p < 0.01) and empathy (β5 = 0.88, p < 0.01) of the quality related to public services in Mexico. The study’s key contribution is that it discovered that implementing a QMS in accordance with the ISO 9001: 2015 standard has an impact on the quality of public services, with the most influential quality of response. Similarly, the assurance and dependability of service quality turned out to be important in providing public service quality.
Research limitations/implications
In this paper, the QMS was only evaluated as a variable that intervenes in the process of obtaining quality in public service under the ISO 9001 standard in its 2015 version. In this regard, the results’ trustworthiness is limited to the extent that the findings may be generalized in the state of Guanajuato, Mexico’s public service. As a result, the scientific community is left primarily focused on service quality to promote new future research.
Practical implications
The ISO 9001: 2015 standard’s QMS is one of the tools for success in both the commercial and government sectors. However, there are practical limitations, which focus on the time during which managers exercise their vision in the public sector: first, the dynamics that managers play in public policy; second, the length of time they have served in public office; and third, the interest of directors of public institutions to improve the quality of service provided by the government. Other practical consequences concern organizational culture and identity, public servant commitment, senior management or secretaries of government, as well as work and training.
Originality/value
The findings of this paper are important and valuable because they foster knowledge generation in the public sector through the ISO 9000 quality area. A model that permits the adoption and implementation of a QMS based on the ISO 9001: 2015 standard in public organizations that seek to provide quality in their services offered to the user is also presented to the literature. Similarly, the paper is important because there is currently insufficient research focusing on the variables examined in the context of public service in Mexico.
