Structural analysis of a process map: re-work (self-loops) and transfers

Types of process flow structural changes

Process mining can reveal two main types of structural changes in process flow fabric: self-loops / re-work (repeated activities) and transfers in-between different activities. 


Examples Self-loop Transfer
Healthcare post-surgery re-admission to hospital ward;

repetition of the same kind of lab tests

in-between hospitals | wards
Manufacturing re-servicing of a pallet by the same manufacturing cell (processing errors detected at the exit from the cell);

re-circulation of pallets on the same conveyor belt (bottleneck detected further in the line)

in-between manufacturing cells | conveyors | robots 
Insurance re-submission of a claim  transfer of claim processing from one service provider to another

Wanted or unwanted? 

Wanted (and expected) process flow transitions  are generally dictated by upper management / high level controllers, and often are included as normative guidelines. 

Unexpected transitions are footprints of waste, i.e. system inefficiencies / malfunctions, redundancies and unnecessary allocation of processes / time / resources.
