The integrated management system ISO audit benefits over individual ISO audits

The research study intends to analyse the effectiveness of the Integrated Management System over an individual management system or ISO audits like ISO45001:2018, ISO 14001:2015, and ISO 9001:2015. We prepared the hypothesis model to understand the IMS effectiveness over individual standards or management systems during the ISO audits at the company. We used the quantitative research technique with independent variable as IMS and dependent variable as operation performance evaluated during ISO audit. We prepared questionnaires to check the improvement of some key objectives of the company after the IMS application. The questionnaires were circulated among a sample of the 150 employees working in the company of 10,000 employee population. We received 110 responses. We concluded from the above study that IMS helps to save repetitive documentation time, improve synergy between different auditing systems, audit efficiency, and final customer trust with satisfaction.
