The plugin that helps alleviate inconsistencies in company names is the Normalization Data Services plugin, which is part of the ServiceNow IT Asset Management suite1.
The Normalization Data Services plugin provides a set of features and capabilities that enable you to standardize and normalize data across various tables and fields in ServiceNow, such as manufacturer names, model names, software names, and company names12.
The Normalization Data Services plugin uses a combination of rules, dictionaries, and algorithms to identify and correct data inconsistencies, such as spelling errors, abbreviations, synonyms, and duplicates12.
The Normalization Data Services plugin can help you improve the quality and accuracy of your data, reduce manual efforts and errors, and enhance reporting and analysis12. References:

Delegated Developers are granted access only to scopes in which they are working1. A scope is a set of application files and data that are isolated from other applications on the same instance2.
Scopes allow developers to create and modify applications without affecting the functionality or security of other applications or the platform2.
Delegated Developers can be assigned developer permissions for specific scopes by an application administrator or a system administrator1. These permissions determine what types of files and data they can access and modify within the scope1.
Delegated Developers can also request cross-scope access to access resources from another scope, which must be approved or denied by the owner of the target scope1.
Delegated Developers do not have access to interfaces, APIs, or instances, unless they are explicitly granted by an administrator or a cross-scope request1. References:
