IS.5:5.3 - Continue among independent carriers

Several independent repair practitioners use a published diagnostic method. They have no common employer and do not communicate as a community. The source publisher maintains the explanation and a correction channel; each practitioner supplies its own tools and follows the method’s applicability limits.

The support question is whether those contributions continue to make the practice available. A maintained correction, discoverable source and actual local access can be sufficient. If a new equipment family breaks an assumption, the publisher needs a qualified method revision or an explicit limit; a new discussion group would not repair the missing diagnostic operation.

A later proposal for peer learning can be useful if its intended contribution warrants the work. It is an additional obtaining way, not evidence that the earlier independent practice was impossible.
