Data (pirate ship) is a valuable asset in (pirate) organizations. Data Owners (captains) are usually senior managers in the organization that are accountable for data and have the authority to make decisions about data. They appoint Data Stewards (deckhands) to do all the work.
Data Stewards usually understand data much better. Their role is to test quality, fix data, document it, write definitions, policies and rules. Data Stewards is a role, and does not have to be job title.
Data is becoming an asset. An asset that should be managed, just as any other key asset – customers, employees, equipment or materials. It even got its own place in the C-suite – in the role of Chief Data Officer (CDO). The role begun in 2002 at Capital One, and has been becoming more popular ever since (according to Gartner – there were 15 CDOs in 2010, 400 in 2014 and 4,000 in 2017). But for many, it’s still unclear what it actually is.
