The three major management systems—quality, environment, and safety—are key. Consistent product quality, the environmental impact of production processes, and worker safety management are essential. Specific industries such as medical devices (ISO 13485), food products (ISO 22000), and cosmetics (ISO 22716, GMP) require dedicated standards.

Construction : ISO 9001, ISO 14001, ISO 45001

Due to the high risks associated with construction quality, site environment (noise, dust, waste), and worker safety accidents, these three certifications are widely regarded as the industry standard. They are a critical evaluation factor in public bidding.

Information and Communication : ISO/IEC 27001, ISO 9001, ISO/IEC 20000-1

Protecting customer data and key information assets is the top priority, making information security (ISO 27001) the most crucial. Stable IT service delivery (ISO 20000-1) and service quality (ISO 9001) are also key.

Transportation and Storage : ISO 9001, ISO 14001, ISO 45001

The key aspects are the timeliness, accuracy, and standardization of transportation processes (ISO 9001); systematic management of negative environmental impacts such as exhaust gases, noise, and waste (ISO 14001); and the safety of drivers and workers (ISO 45001).

Accommodation and Food Service : ISO 22000, ISO 9001, ISO 14001

Hygiene management throughout the entire process, from receiving ingredients to serving customers, is essential, making food safety (ISO 22000) the most important.

Healthcare and Social Work Services : ISO 9001, ISO 13485

Quality management (ISO 9001) is fundamental for improving the quality of medical services and patient satisfaction. Specialized standards are essential for professional areas such as the use/manufacturing of medical devices (ISO 13485).

Arts, Sports, and Recreation Related Services : ISO 9001, ISO 14001, ISO 45001

In the arts, sports, and recreation services industry, customer safety and satisfaction are key to business success. Therefore, accident prevention (ISO 45001), quality management (ISO 9001) to enhance service quality and customer satisfaction, and environmental management (ISO 14001) to achieve eco-friendly operations by systematically managing waste, energy, and water usage from large audiences are important.

Wholesale and Retail : ISO 9001, ISO 45001

Service quality (ISO 9001), including stable product supply, inventory management, and customer service, is key. Ensuring worker safety (ISO 45001) is important when operating large logistics centers or stores.

Finance and Insurance : ISO/IEC 27001, ISO 9001, ISO 37001

Information security (ISO 27001) to protect customers' financial information and assets is the top priority. The quality of financial products and services (ISO 9001) and the organization's transparency and compliance management (ISO 37001) are the foundation of customer trust.

Real Estate : ISO 9001, ISO 45001

Quality management (ISO 9001) is important for the reliability and consistency of services such as brokerage, management, and appraisal. Ensuring facility safety (ISO 45001) is essential for building management.

Administrative, Support, and Rental Services : ISO 9001, ISO 45001

Ensuring the quality (ISO 9001) of various B2B services such as staffing, facility management, security, and call centers, as well as the safety (ISO 45001) of dispatched and managed personnel, is a key element of contracts.

Public Administration, Defense, and Social Security : ISO 9001, ISO 37001, ISO 27001

The quality of public administrative services (ISO 9001) and anti-bribery measures (ISO 37001) for the integrity and transparency of public institutions are key. As sensitive personal information is handled, information security (ISO 27001) is also important.

Education Services : ISO 21001, ISO 9001

ISO 21001, a management system specialized for educational services such as curriculum design and learner management, is the most suitable. It is an international standard that enhances the credibility of educational institutions.

Activities of Membership Organizations, Repair and Other Personal Services : ISO 9001

Ensuring customer satisfaction and trust through consistent quality (ISO 9001) of various services such as member management, beauty services, and laundry is the foundation of the business.

Water Supply, Sewerage, Waste Management, and Remediation : ISO 14001, ISO 9001, ISO 45001

As the business itself is closely related to the environment, environmental management (ISO 14001) is the most critical certification. Safety during the waste treatment process (ISO 45001) and service quality (ISO 9001) management are also important.

Professional, Scientific and Technical Services : ISO 9001
