I'm not sure how useful this construct is. For example consider a software developer. Is she a thinker, builder, improver or producer? Probably all of the above. An author is responsible for both the ideas and their implementation. What about a support person in a call center? Historically we might say he runs a repeatable process, but increasingly we want him to show creativity and initiative working within constraints, and to help us improve the system. A soldier? Used to be that the job was about following orders, but increasingly it requires creativity and initiative as well as execution.

I took a look at the Adler article and have a hard time seeing it as anything I could find useful in recruiting or hiring.
