Values manager vs. value manager [duplicate]

When writing software documentation I very often have to describe things like a value manager, a value cache or a device map. These are usually components of the software system.

In practice the manager does of course not manage a single value but many and the map does not map only a single device etc.

My question is: is it more common to speak of a values manager instead of a value manager and of a devices map instead of a device map etc.?

Solution 1:

The job title is awkward but clear enough. “Value” is about cost estimates, savings, and such. “Values” is about watching the moral compass.
