Debate on the effectiveness of ISO 9000

The debate on the effectiveness of ISO 9000 commonly centers on the following questions:

• Are the quality principles in ISO 9001:2000 of value? (Note that the version date is important: in the 2000 version ISO attempted to address many concerns and criticisms of ISO 9000:1994).
• Does it help to implement an ISO 9001:2000 compliant quality management system?
• Does it help to obtain ISO 9001:2000 certification?
