- Certificação pela ISO 9000 não é gestão da qualidade!Publication . Cândido, CarlosMas o que disse então este nosso conferencista de tão estimulante? O Professor apresentou os resultados de um estudo que efectuou em Espanha. Com base num inquérito realizado aos turistas no seu país, construiu um indicador do grau de satisfação para cada destino turístico (Costa da Luz, Costa do Sol, etc.). Paralelamente, o estudo recorria ainda à consulta do número total de empresas turísticas certificadas pela ISO 9000. Analisando estes dados, seria de esperar que os destinos que apresentam graus de satisfação mais elevados dos turistas fossem aqueles com maior número de empresas certificadas. Ora, surpreendentemente, o que aquele Professor descobriu foi exactamente o contrário. Os destinos turísticos com maior número de empresas certificadas apresentavam indicadores de satisfação dos turistas mais baixos!
- The financial impact of a withdrawn ISO 9001 certificatePublication . Cândido, Carlos; Coelho, Luís; Peixinho, RúbenThe purpose of this paper is to assess to what extent the loss of the ISO 9001 certification affects the decertified firms’ financial performance. Design/methodology/approach – Using standard event-study methods, this paper matches a sample of 143 Portuguese companies that lost their ISO 9001 certification with similar non-event counterpart firms (according to return-on-assets and size) and compares the performance of these two groups of firms using financial data collected from the AMADEUS database. Findings – Results show no statistical significant differences in the financial performance (as measured by return-on-assets, return-on-sales, and sales growth) between companies that lost their ISO 9001 certification and their matched firms. Although the literature suggests that certification improves firms’ performance and that the benefits of certification may last over long periods of time, this paper’s results suggest that, after decertification, companies do not exhibit over or underperformance in their operations vis-à-vis comparable firms that do not undergo the same event. Originality/value – As far as the authors are aware, this is the first study assessing the impact of ISO 9001 certificate withdrawal on the decertified firms’ financial performance.
- Firm preparation for ISO 9001 certification: the case of the hotel industry in PortugalPublication . Esgarrancho, Sandra; Candido, CarlosThe purpose of this study is to assess whether companies conduct preparations, such as managing culture, before starting to implement an ISO 9001 Quality Management System (QMS). Based on a literature review, the paper develops a model of firm preparation for ISO 9001 certification and several research hypotheses. The survey research method adopted consists of data collection through questionnaires – sent to hotels of four and five stars, in Portugal, in two different moments (2012 and 2014) – and of a longitudinal data analysis based on non-parametric statistical tests. Results show that the majority of companies conduct preparations before starting to implement an ISO 9001 QMS. However, most companies do not assess their initial situation, nor do they plan for the preparations. One of the significant implications from this research is that a more coherent and integrated approach in ISO 9001 preparation is required. Other implications for practice and for research are also noted. This is the first study, as far as the authors are aware of, that addresses the topic of planning for the preparations that a company can make before starting to implement an ISO 9001 QMS.
- Factors influencing firm propensity for ISO 9001 withdrawal: Evidence on decertification tendency and antecedentsPublication . Ferreira, Luís M. F. R.; Cândido, Carlos J. F.There are approximately 1,000,000 ISO 9001 certified companies worldwide. Every year, one third of these companies must decide whether to renew, or not, their certificate. The number of companies that abandon or lose the certificate has been growing and reached an average of 60,000 per year. Considering that there is currently no theory or model to explain this propensity of firms to decertify (18%), the aim of this study is to identify the underlying factors influencing firm propensity for ISO 9001 withdrawal and to analyse the relationships between these factors. In order to achieve these aims, the research develops a structural equation model (PLS-SEM), from extant literature, and estimates the model with survey data from a sample of 221 ISO 9001 certified companies. Results show that the main antecedents to decertification propensity are barriers to the initial certification, (absence of) external certification benefits, decertification motivations, and expected performance after decertification. This is the first study to address decertification from a systemic and comprehensive perspective and to present a structural equation model of the phenomenon. The study makes an integrated contribution to explain decertification propensity with the help of novel research variables. Results suggest several contributions to theory, and practice, and contribute to clarify a major contradiction in the field.
- ISO 9001 internal decertification motivations: exploring barriers and benefits of certification as withdrawal antecedentsPublication . Candido, Carlos J. F.; Ferreira, Luis M. F. R.Thousands of companies worldwide lose their ISO 9001 certification every year. Considering the relevance that this decertification phenomenon has achieved, this study examines the internal motivations for decertification and explores the relationships between motivations and firm's previous certification barriers and benefits. To achieve this purpose, the study develops a partial least squares structural equation model (PLS-SEM) from the literature and estimates the model based on data collected from a sample of 248 certified organisations. Results reveal that the main antecedents of internal decertification motivations are external factors, namely external decertification motivations and external certification barriers. External barriers do not disappear after certification and have a stronger influence on motivations than (lack of) certification benefits. Internal and external benefits have a small effect on motivations, and internal barriers have no significant effect. In addition, the relationship between external barriers and internal decertification motivations is mediated by external motivations. Similarly, the relation between external benefits and internal motivations is mediated by internal benefits. Currently, there are no other studies on the relationship between internal and external decertification motivations, nor studies identifying the antecedents of both motivations. Thus, the research findings constitute novel contributions to the literature and suggest relevant implications for practice.
- ISO 9001 maintenance, decertification and recertification: A systematic literature reviewPublication . Camango, Crispim; Cândido, Carlos J.F.Previous research on ISO 9001 certification maintenance, decertification and recertification is fragmented and lacks an integrated theoretical framework. Thus, the aims of this study are to provide an overview of current research, develop an integrated framework and identify research gaps. The research methodology consists of a systematic literature review (SLR) which starts with the definition of a research protocol, proceeds with searches in Web of Science and Scopus, and selects a final sample of 32 articles for analysis. Results show that the research interest in certification maintenance, decertification and recertification is growing, but is still scarce. Extant research focuses on certification maintenance factors, benefits and frameworks; decertification reasons and consequences, and recertification impact on efficiency. There is a lack of consensus on these topics, but the data extracted from the literature is used to develop a theoretical framework of what companies do in the post-certification period. The framework identifies the main variables involved in certification maintenance, decertification and recertification, and establishes the main relationships between them. This is the first SLR conducted on these topics, which provides the first integrated framework of the research phenomena, a comprehensive list of research gaps to guide future studies, and relevant management recommendations.
- Determinants of expected performance after ISO 9001 certification withdrawalPublication . Candido, Carlos; Ferreira, Luís M. F. R.ISO 9001 certification impact on firm performance has been extensively researched. However, despite the high number of firms withdrawing from this certification, the impact of decertification has not received much research attention. This study contributes to filling this gap by analysing the factors that influence the expected performance after decertification (EPAD). The study reviews relevant literature and develops a structural equation model (PLS-SEM) with data from 231 certified organisations. Results reveal that the main factors influencing EPAD are external decertification motivations and internal certification benefits. Internal benefits have a U-shaped relationship with EPAD and external decertification motivations a positive linear relationship. Results show also a negative direct impact of external benefits on EPAD, which is counterbalanced and cancelled by a positive indirect impact from the same variable. Certification barriers and internal decertification motivations have no significant effect. This study is the first to identify and analyse the factors affecting EPAD and, as such, the study findings constitute innovative contributions to the literature. These findings have theoretical and practical implications for (1) the estimation of EPAD, (2) the decision to renew (or not) the certificate, and (3) further suggest that EPAD is a better predictor of decertification than past certification benefits.
