A snap back time study was conducted on a tablet compressor machine where machine time is completely automated and a full time worker requires some manual tasks. Necessary information is as follows;

Pieces produced per cycle = 2

Average OT for manual tasks time = 5.75 min

Average OT for machining time (power feed) = 4 min

Performance rating = 105 %

Machine time allowance = 5%Manual task allowance = 10%

Cycle time = Manual time + Machining time
