If you’re an industrial business that has to comply with ISO 9001 or any other derivative of an international manufacturing standard such as TS 16949 for those supplying the automotive industry, or maybe GMP for those supplying pharmaceuticals and healthcare, then running an annual customer satisfaction survey is a condition of doing business in your industry.
Any international manufacturing certification (such as ISO 9001, TS 16949, or GMP) requires regular customer satisfaction surveys, and they also require that those survey results drive the improvements in the business.
