• Scrum guide is intentionally unclear and incomplete (lacks methodological guidelines / foundation rules. Therefore one is forced to interpret terms and meanings. 
• Vagueness makes it possible to interpret scrum differently to fit different peoples' situations and opinions. Allows people to generate any scrum interpretation they want to agree with. 
• This vagueness has created an entire commercial industry around scrum, selling frameworks / scaled models. 
• Because of above, Scrum cannot be judged as wrong or right. Every interpretation appears okay within its own context.
• Absence of guidelines leads people to count a particular term in the scrum guide hoping that a higher frequency of a term would mean something. 
• None of the Scrum guides explain how Scrum views or defines value, what product management is, nor how value is tied to the product manager role or product management.
