What is the benchmark to decide which SCOPE is best suited for app development ?

[Snehal13]

1) What is the benchmark to decide whether development should be done in custom scope or global scope ?

2) In the event of changed requirements and needs realignment, can app development changes be moved to custom scope from global scope or vice versa ?

Any ServiceNow utility or tool to do the same, If not, what are the options on manual front.

Hi.

I will answer about number 1.

Application scope identifies and restricts access to application files and data.

Ensures that no other application interferes with the normal functioning of this application unless explicit permissions are granted.

You can judge whether the change is system-wide or not.

Thank you.

I think you misread my question. Your response talks of what the "scope" does.

I want to know "what" decides whether app must be developed in global or custom scope ?
