Factors correlating with revisions of ISO 9001 Quality Management Standard
Because of the importance placed on quality, many organizations are implementing the International Organization for Standardization (ISO) 9000 family of quality management standards. Today, these standards have been adopted by more than one million organizations in 170 countries around the world. The success of ISO 9001, one standard within the family, which has attracted significant attention of academics and practitioners, applies to quality assurance in design, development, production, installation, and service. This particular standard sets out quality management system criteria and provides guidelines and tools for organizations and companies to ensure that their products and services meet consumer expectations. Effective implementation of such systems can lead to a significant increase in a company`s performance, stability, and competitiveness. Since its initial publication in 1987, ISO 9001 has been revised four times, often justified by market changes. Macroenvironmental data representing six categories, used to track market changes from 1987 through 2017, were obtained from various databases. U.S. macroeconomic data were obtained from the U.S. Bureau of Labor Statistics, U.S. Bureau of Economic Analysis, and U.S. Bureau of Statistics, whereas global data were obtained from the World Bank database. Levels of correlation among factors were quantified using multivariable analysis. By utilizing multiple regression analyses, both U.S. and global sets of data indicated a statistically significant trend in the gross domestic product (GDP) over the study period. Consequently, an autoregressive integrated moving average (ARIMA) model was fitted to the U.S. data, which was then used to forecast future revisions of the standard. Results indicate that with a sustained increase in the U.S. GDP, revision periods are expected to decrease. According to the model, revisions of the ISO 9001 standard are likely to take place by 2019. U.S. companies that are certified under ISO 9001-2015 have two years to plan and budget for recertification.
