I think that the construct of the job, with its defined skills, effort, responsibilities and working conditions, is a key limiting organizational factor for the creative economy …

A big BINGO ! to that.

The Taylorist job concept, with its constrained set of objectives, skills and defined relationships to other jobs is by its fundamental logic set opposed to the dynamics of individuals and groups operating in networks. A job is like a part in a machine .. a spark plug, or a filter, etc. The machine is supposed to function the same way and do the same thing all the time, which is fine for mass assembly lines but less and less effective an a constantly shifting-and-moving environment.
