At BISON-BIAL we take great pride in the fact that the BISON logo has long been a symbol of excellence, a reputation that has been supported by our ISO 9001:2001 certification. With the advent of globalization and increasing international trade came the need for an internationally recognized benchmark for quality. As a result, in 1987, the International Organization for Standardization (ISO) created the ISO 9000 series for quality standardization. ISO 9001 is comprised of universal quality management standards, based on eight principles: customer focus, leadership, involvement of people, process approach, system approach to management, continual improvement, factual approach to decision making, and mutually beneficial supplier relationships. In order to maintain its ISO 9001 certification status, a company must undergo multiple internal audits each year and an external audit every two years. In order to confirm compliance with the requirements of ISO 9001 and maintain certification, the external certification body, the Polish Center for Testing and Certification (Polskie Centrum Badan i Certyfikacji) conducts annual audits of supervision.
