TC 176 / SC2 should follow relevant ISO 9001 principles/requirements in making the revision, including the following:
1. As per ISO 9001:2015 Section 4.2, they should understand the need and expectation of organizations that follow ISO 9001 for a clear and helpful standard.
2. As per ISO 9001:2015 Section 5.1.2 c, the top management of TC 176 / SC2 should ensure that the focus on enhancing customer satisfaction is maintained. It would be helpful if they also monitor customer satisfaction per section 9.1.2 and analyze data per 9.1.3 to help them in focusing on enhancing satisfaction and making changes that will improve customer satisfaction.
3. As per ISO 9001:2015 Section 7.1.6, they should ensure that they have the necessary knowledge to write a good standard. This should include gathering knowledge from customers (standards users) and incorporating the knowledge of standards users in how the standard is written. For subjects where the committee lacks sufficient knowledge (such as knowledge management and risk management), they should refrain from writing requirements or they should acquire sufficient knowledge.
4. As per ISO 9001:2015 Section 7.2, they should determine the necessary competence for standard writers and ensure that only competent personnel are involved in writing the standard.
5. As per ISO 9001:2015 Section 8.2.2, they should ensure that they can meet the claims that ISO makes about ISO 9001. Currently, ISO's website page for ISO 9001 claims that "Using ISO 9001:2015 helps ensure that customers get consistent, good quality products and services, which in turn brings many business benefits." Considering the recent decline in ISO 9001 certifications, and the significant user dissatisfaction with ISO 9001:2015, it is dubious that ISO 9001:2015 "brings many business benefits" - large numbers of businesses don't normally drop something which is bringing them many benefits. Either TC 176 / SC2 should write a useful standard which "brings many business benefits" or ISO should revise its claims to something more accurate, such as "ISO 9001 certification can help an organization to make sales to organizations which require external providers to have ISO 9001 certification."
6. Perhaps most importantly, as per ISO 9001:2015 Sections 8.3.3 - 8.3.5, TC 176 / SC2 should consider the functional / performance requirement for the standard that it be clear, unambiguous, and auditable, and should verify that the finished standard is clear, unambiguous, and auditable.
