Users can define a follow-up NIs in the Diagnosis so that these NIs can be executed under certain conditions (inside the if/else clause), achieving multi-staging diagnosis.

With the Follow-up NI introduced:

▪Users can execute NIs based on conditions instead of executing all of them, then the diagnosis can be more efficient and the impact to live network could be minimized.

▪The follow-up NI diagnosis also can reduce unnecessary or redundant messages, then increase the readability to users, less noise.

▪Make it feasible that reuse other well-created Intents in customized NI diagnosis.
