ISO standards are widely used by organizations to define processes and maintain consistency in different areas of business operations. Standards such as ISO 9001, ISO 14001, ISO 45001, ISO 22000, and ISO 27001 are applied across manufacturing, service, healthcare, education, food, and information technology sectors. These standards provide a framework for quality management, environmental management, occupational health and safety, food safety, and information security. Many organizations adopt ISO systems to document procedures, monitor performance, and maintain records that support ongoing business activities. The use of internationally recognized standards helps organizations follow structured management practices and maintain documented processes across various functions.
