Abstract
Purpose
The purpose of this paper is to present a framework to assist the selection of certification bodies in the implementation of quality management system (QMS) based on ISO 9001 taking into account a set of criteria organized in a multi-level hierarchical form. To deal with this complexity, the multi-criteria decision-making method (MCDM) analytic hierarchy process (AHP) was used in this research.
Design/methodology/approach
The research was conducted in small and medium-sized companies certified to ISO 9001. The MCDM method AHP was used as a method for developing the model to support the selection of certification bodies.
Findings
This paper provides a framework for companies seeking to hire certification bodies, mainly for ISO 9001 certification, which help identify the companies that best fit the certification objectives. Additionally, a ranking of the main criteria to select certification bodies for ISO 9001 was obtained.
Research limitations/implications
The decision-making method was applied to Brazilian companies from different sectors. As the results can vary between regions and sectors, this is a limitation of the research. In addition, the number of ten respondents could be higher to increase the robustness of the results.
Practical implications
The model assists companies looking for certification, mainly ISO 9001, in the selection of certification bodies contributing in the search for deeper implementations of QMS.
Originality/value
This work has the originality of the application of a decision-making method in the final process of ISO 9001 certification, scarce in the literature. In addition, it defines weights for the criteria involved in the process of selecting certification bodies.
