To maintain product delivery times, Ready Energy  production lines have increased work and handling of finished material and raw materials have taken a backseat. Initially, the delivery of finished material was successful. Production, handling, shipping and delivery times were optimal. However, poor management due to the speed with which the product is required to be finished has caused its quality to drop and customers are not completely satisfied.

 

Ideally, about 2000 batteries are manufactured per week divided into two shifts, with a rate of 95% of the total produced successful. 3% goes to reworking the product and only 2% of the total production is discarded.

 

Currently, 3,250 batteries are manufactured per week divided into two shifts. The successful battery rate is 82%. The percentage of rework on failed products is only 3%, while scrapped material is 15%.

 

Group leaders on production lines have given the order to discard products that require rework that takes considerable time. Likewise, it has been requested that material with defects (minor or considerable) be immediately discarded.

 

On the other hand, the management of the material for manufacturing the product faces its own problems. The fact that the quality of materials has dropped has received little attention. To date, no approaches have been carried out with suppliers to address this fact.

   Identify the times in the process cycles found in the case. Then create a table that contains the following elements and fill it with the corresponding information: 

a)     Ideal process time per shift.

b)    Current process time per shift.

c)     Observations supported by the phases of Porter's value chain.

 

d)    Possible causes.

e)     Personnel involved.
