CEO and COO

From Marissa Lavin of http://www.successfulculture.com/when-the-ceo-must-become-the-cpo-chief-process-officer/

Traditionally, the CEO is responsible for the “heart” of the organization… the vision, culture, mission, strategy, and values. They are the “Chief Evangelist Officer,” or the “Chief Cultural Officer” or even the “Chief Emotions Officer” (yes I’ve seen that one too).

Conversely, it’s usually the COO that is responsible for the “blood and guts” of the organization” – the person that ensures the day-to-day and long-term operations within the organization can support the vision.
