$r11$ Homework: Process Analysis and Resource Utilization

A medical equipment testing and calibration service $is$ shown below. The customer usually brings the equipment $to$ the service center. The service process requires service technicians $to$

perform three process steps #$1to$ #$3.$ Each technician $is$ cross$-$trained $so$ they can perform any $of$ the three steps. The inspector does step #$4$ alone. After step #$4,$ two parallel work

activities are performed. That $is,$ a shipping clerk packs the work $(step$ #$7),$ while simultaneously, a billing clerk prepares the invoice $(step$ #$5),$ and the customer $is$ contacted $by$ phone

for pick$-up(step$ #$6).$ The average throughput $is$ three equipment units per hour.

The table below shows the work content $of$ the process steps, activity times $in$ minutes per unit, shared and non$-$shared work activities, and the type $of$ resource required. There are three

service technicians $on$ duty, one inspector, one billing clerk, and one shipping clerk.

Round your answers $to$ the nearest whole number.

$a.$ What $is$ the service rate for the service technician?
