  1. Construct a Fishbone Diagram




PROBLEM:                 Unable to meet the production quota resulting to opportunity loss



CAUSES:                     High Rate of absenteeism (Laziness of workers)




Idle Time of Workers (Laziness)


                                    Shortage of Materials


                                                Due to under-stock (supplier’s problem)


                                                Insufficient Number of Trucks (supplier’s problem)


                                    Longer Machine Downtime


                                                Lack of Technician (Machine cause)


                                     Bottleneck


            Poor Layout



DATA:


The company operates 9 hours a day with one hour organized lunch break


Total working days per month is 20 days


Production Quota is 40,000 units per day


Actual Output is 16,000 units per day


Rate of absenteeism is 8 workers per day


Machine Capacity is 4000 units per day per machine for 8 hours


Total number of workers is 50 workers (based on required quota)


Lost units due to under-stock of materials is 2000 units.


Truck capacity of 2000 units of raw materials equivalent to 1000 units of production output (2:1 ratio of raw materials to output)


There are 8 available trucks instead of 14 trucks for the required units of raw materials


Machine repair takes 4 hours per breakdown


There is only one machine technician available causing longer machine repair time


5 persons per day (Idle 50% of their time)


Lost units due to Bottleneck is 1,600 units


Lost units due to Poor Layout is 2,000 units
