Why are public frameworks, such as 1TIL, attractive when compared to proprietary knowledge?

Public frameworks such as ITIL are thoroughly documented and openly available, enabling organizations to easily adopt, replicate, and transfer practices across teams or organizations. Because proprietary knowledge often exists only in the heads of individuals or in internal, unpublished documents, it creates dependency and risk. This makes well-documented public frameworks far more portable and scalable.

Cost is not guaranteed to be lower - public frameworks can involve licensing fees, training costs, and implementation expenses that may match or exceed proprietary alternatives.

ITIL and most public frameworks are deliberately descriptive and adaptable, not prescriptive - they provide guidance and best practices but do not dictate exact steps.

Proprietary knowledge is typically tested only within the limited environments of the organization that created it, not across a wide range of diverse environments.
