unmanageable sytems are those where the communication necessary for control cannot be coded because control requires a communication interface between the one system and another - so where the variety of states of each system is unequal there must be both compression and expansion in communication - that is, the varieties must be compressed to be expressed to the system which has less, and expanded where there is communication back from that system
therefore a 1:1 mapping is not in principle possible - so no means of communication that depends on a 1:1 mapping can be used for control, which means that it cannot be by software coding which requires 1:1 - as an example, a computer monitor is a mesh of interfaces that transform internal electro-magnetic states via databuses, oscilloscope, fluorescent material etc., to electro-magnetic states cognizant in our visual range of wavelengths. a differential equation of the whole thing on a microscopic level is in contradistinction to the intuitive notion of interface that resides on a human scale of cognition, ie relatavistic and "endovistic"
if a system is unmanageable there are three possible strategies towards its control:
1) reduce it so that its variables are contained by the posited control system, 2) change the organisational structure (how their management works), 3) change attitude to unmanageability
1) is an attempt to bring within range of the controlling system, to reduce it, for example, to a narrative object. it is a methodology that can be despotic - when it appears as permament and all-pervasive; or benign, where individual variety is given up temporarily in order to gain something else. (examples might be laws for the former and playing sports for the latter.)
2) the use of mutual control within groups where instead of one system controlling all the others, they all participate in shifting coalitions of group control, modifying how control operates (example of micro-democracies)
3) the acceptance of uncontrollability - Deleuze's stutterer is the one who messes up all codes and transmits "decoded flows of desire", stuttering in his own language. Anarchical machines are those machines that experiment in confounding the codes and "liberating the flux of revolutionary desire"
