The right number of Perspectives varies by organization and depends on your requirements.
Typically, organizations tend to require 4 to 6 Perspectives to cover their entire infrastructure. When determining how many Perspectives to create, consider how many lenses you want into your infrastructure on an ongoing basis.
By default, you can create a maximum of 6 Perspectives in the platform. As the number of Perspectives grows, managing asset membership within Perspective Groups incurs a high computational and maintenance cost.
