Public health accounting/medical billing software. Right now we are "sponsored" by the CTO, but he's quite hands off and leaves us a lot of autonomy. Our charter is heavily influenced by the scientific method and intense, rigorous study, which is paradoxically not as regimented in the business-level work we do because ever changing priorities and customer influenced decision making by our project managers and enterprise leaders.

The guild, not beholden to the enterprise itself we are INFINITELY better about scope creep and velocity for the projects originating from and ultimately brought into maturity by us-without that outside influence of the rest of the business.

Metrics was actually the topic of our most recent congregation, looking into new and creative ways of establishing both performance and delivery metrics aligned with the DevOps way for our own "pet projects" as a guild, which we (hope) translate back up and into what we do for the day-to-day business objectives. So none. Yet :)
