Step 1 Step 2 Step 3 Step 4 Unpack & place on unit Strip off bad habits Scrub & clean mind Insert modern methods 1 minute 1.5 minutes 0.8 minute 1.0 minute

Questions a/ what is the current max output of the process? b/ should we add a worker to step 2 ( as it is bottleneck)?

Answers a/ Operation Output unpack & place on belt (60 min per hour/1 minute per order) X 8hours = 480 students per day
Strip off bad habits (60 min per hour/1.5 minute per order) X 8hours = 320 students per day scrub & clean mind (60 min per hour/0.8 minute per order) x 8 hours = 600 students per day
Insert modern methods (60 min per hour/1 minute per order) X 8hours = 480 students per day
Polish & pack (60 min per hour/1.2 minute per order) x 8 hours = 400 students per day
Max output = 1600 students per day step 2 can only produce 320 students per day which is where bottleneck is.

b/ unpack & place on belt 480
Strip off bad habits x 2 workers 640 scrub & clean mind 600
Insert modern methods 480
Polish & pack 400 step 2 can now do 640 students per day but step 1 (480) is the max output in one day but will satisfy the order of 2000 students per week.
