Custodian
Role Attribute
Purpose
The Custodian improves quality by providing guidelines for other team members.
The Custodian investigates work done to ensure cohesion and completeness.
Notes
The Custodian protects a value stream from deteriorating due to bad quality.
The Custodian is similar to the System Owner in the “Spotify Model“ and the System Architect/Engineer in SAFe.
The Custodian is not the same as an Inspector. The Custodian (such as engineers and architects) would monitor how part of a value stream is created. The Inspector (such as testers and quality managers) would monitor how the value is delivered.
Rules / Constraints
There can be multiple Custodians, possibly with different areas of expertise.
