         16 . A system comprising:
 one or more processors;   memory accessible to at least one of the processors; and   processor-executable instructions stored in the memory and executable by at least one of the processors to instruct the system to:
 operate a pump system; 
 determine a condition associated with the pump system, wherein the condition comprises a rod failure time, a rod guide failure time, or a tubing wear parameter; and 
 control the pump system based at least in part on the condition. 
   
     
     
         17 . The system of  claim 16 , further comprising at least one electrical interface that is operatively coupled to at least one pump system for control of at least one of the at least one pump system.
