What is Production Data?

I received an interesting email recently that made me stop and think a bit… so I thought I’d blog about it. Basically, the email posed the question in the title of this blog entry – “What is production data?”

The email read as follows:

I’m looking for a one paragraph definition of “production data.” What do you think of this: “Production data is data recorded for the purpose of controlling/managing/reporting/researching events, processes or states.”

I’m trying to get around the belief that data recorded by a development team to manage its projects and resources is somehow less than production data. To me it should be regarded as the development team’s “production data” and so I’m looking for a definition that satisfactorily encompasses that belief, as well as encompassing regular business production data.

You know, I do not recall ever seeing an actual definition of the term “production data.” The above definition is a good starting point, but I do not think it is complete. The author of the email makes a good point about different types of production data. The data used by an application development team to conduct their business (writing computer programs to support business processes) is definitely production data… to the application development team.

Here is my take on a definition:

Production data is information that is persistently stored and used by professionals to conduct business processes. It must be accurate, documented, and managed on an on-going basis to ensure its value to the organization.

I say information instead of data because the data must be defined and in context in order to be useful for production work. And I say persistent because even though there may be many forms of transitory data used by production processes, it is the data that is stored over periods of time that needs to be managed.

I think this definition should serve the needs of the emailer… and more. What do you think?

Did I miss anything?
