Abstract
Purpose
The economic effects resulting from the commitment to ISO 9001 certification is a controversial issue. Many authors have concluded about the positive economic effects resulting from the establishment of quality systems in accordance with the requirements established in the ISO 9001 standard, but other authors have not appreciated this positive relationship. The purpose of this paper is to provide a model that facilitates the valuation of the ISO 9001 quality system.
Design/methodology/approach
In the process of developing a valuation model, given the uncertainty this process involves, the use of fuzzy math is very useful. First, as for an internal valuation method, the authors highlight the discounted cash flow in a fuzzy environment. The internal valuation will be completed by external expert opinions. To improve the information supplied by experts, the paper makes use of the experton theory. In this context, the authors propose the aggregation of the experts’ opinion by using basic defuzzification distribution (BADD)-fuzzy induced ordered weighted averaging. Finally, the results undergo contra-expertise. After presenting the theoretical model, the authors proceed with its application by using a case study.
Findings
The paper develops a new method for the economic evaluation of the ISO 9001 certification.
Originality/value
The authors propose the valuation of ISO 9001 quality management system, and they do it using some interesting tools which fuzzy logic offers. In this way, it is possible to eliminate subjectivity and improve the final results.

Abstract
Purpose
This study explores the link between ISO 9001 certification, personal data protection and firm performance using financial balance sheet and survey data. The security aspect of data protection is analyzed based on the major requirements of the General Data Protection Regulation and mapped to the relevant controls of the ISO/IEC 27001/27002 standards.
Design/methodology/approach
The research analysis is based on 96 ISO 9001–certified and non-certified publicly traded manufacturing and service firms that responded to a structured questionnaire. The authors develop and empirically test their theoretical model using the structural equation modeling technique and follow a difference-in-differences econometric modeling approach to estimate financial performance differences between certified and non-certified firms accounting for the level of data protection.
Findings
The estimates indicate three core dimensions in the areas of “policies, procedures and responsibilities,” “access control management” and “risk-reduction techniques” as desirable components in establishing the concept of data security. The estimates also suggest that the data protection level has significantly impacted the performance of certified firms relative to the non-certified. Controlling for the effect of industry-level factors reveals a positive relationship between data security and high-technological intensity.
Practical implications
The results imply that improving the level of compliance to data protection enhances the link between certification and firm performance.
Originality/value
This study fills a gap in the literature by empirically testing the influence of data protection on the relationship between quality certification and firm performance.
