This one is really difficult to assess. Their ideas about worker owned and operated businesses are not new, but the idea of "job complexes" is intriguing and would probably benefit workers.
On the other hand, the ideas about consumers planning their consumption over the period of a year and submitting anonymous requests, using computers to assess the bulk of the data involved in these requests, etc really date the book to the early 90s. Google, Facebook, and the owner of this website, Amazon, use tons of user data in much the same way that the authors suggest. Granted, these companies are not worker-owned or operated, so the context is quite different.
In addition, just looking at the planning aspect, this is in general a horrible idea. Even in market economies, most businesses are terrible at planning. People in general are not very good at predicting the future.
