Concurrent  control  takes  place  while  operations  are  going  on  and  is  intended  to minimize problems as they occur. Concurrent control is a control type based on timing that involves the regulation, monitoring and adjusting of ongoing activities that are part of the transformation process to ensure that they conform to organizational standards.  Feedback control takes place after operations are finished and is intended to correct problems that have already occurred.  A feed forward control is a control type based on timing that focuses on the regulation of  inputs  to  ensure  that  they  meet  the  standards  necessary  for  the  transformation process.  Steering control is a technique used to detect deviations and allow corrective actions to be taken while the activity is being performed.
