# ACE Documents (Accountability, Collaboration, Empowerment)

A specific tool used by an **industrial-services CEO** to translate abstract company values into tangible daily work. **ACE stands for Accountability, Collaboration, and Empowerment.** These documents **replace traditional job descriptions** by clearly specifying:

- **what each role owns** (Accountability),
- **how the individual is expected to collaborate** with others (Collaboration),
- **exactly where decision authority sits** (Empowerment), and
- **how success is measured.**

By making these explicit, ACE documents remove ambiguity and **structurally embed the desired culture into the organization's operational fabric** — a concrete instance of the [[concept-system-of-enforcement]] applied to culture. They are the mechanism behind [[concept-ownership-cultures]] and are deployed via [[action-ace-job-descriptions]] under the fifth of [[framework-5x-ceo-disciplines]]. Enrichment note: this is similar in spirit to the role-clarity and empowerment practices in Patty McCord's *Powerful* and the Netflix culture deck.
