What is the significance of template architectures?

In essence, an architectural framework, in this context, is described as a collection of viewpoints that is standard across industry, sector, or organization. 

These frameworks can be used by business analysts as predefined templates to start from when defining their own requirements architecture. 

For example, an organization has defined its own custom requirements architecture that was based on the industry architectural framework published by the International Institute of Business Analysis. This requirements architecture consists of various templates and notational modeling guidelines (viewpoints) that must be applied when a business analyst prepares the requirements documentation for a particular initiative of the organization.
