For Op-1 Time For Per Pcs Production (T) 60/120 .5min

This document provides information from an activity sampling analysis and production summary sheet to calculate the standard minute value (SMV) of various operations. It gives the percentage of time spent on different activities for 8 operations. It also provides the hourly production and time taken per piece for each operation. The SMV is then calculated for the first two operations as the sum of the basic time value, mental/attention time value, and rest/avoidance time value. The individual target rate is calculated by dividing the time period by the SMV.
