A time study is conducted on a process that has three (3) separate operations. The process involves five (5) masons placing 1 cubic yard of concrete for each cycle. Ten cycles of each operation are carried out to improve accuracy. The results of the study are as follows: Operation # 1 #2 #3 Total time (seconds) for 10 cycles or repetitions 975 643 917 Overall total 2,535 seconds (for 10 cycles) The observer assigns the following factors: Allowance = 14%, Rating = 125 % NOTE THAT IT IS NOT NECESSARY TO PROVIDE VALUES FOR EACH INDIVIDUAL OPERATION - ONLY THE TOTAL. a.) Determine a standard time in minutes per cycle for the entire process and record (FOR 1 CYCLE) the values for the following: 1. Select time PER CYCLE: 2. Normal time (seconds)= 3. Standard time (in minutes): b.) Using the standard time for the crew of 5 masons, calculate the work productivity as cubic yards per mason hour of material, OR mason hours per cubic yard. Productivity in: Cubic yards per mason hour OR Productivity in : Mason hours per cubic yard_
