As an operations manager of a firm what significant issues you have to consider while implementing supply chain management? 

Elements of Supply Chain Management (page no, 174) 

Question No: 50 ( Marks: 3 )

Question No: 52 ( Marks: 5 ) 
What is bullwhip effect? What are its consequences? 

Bullwhip effect represents the real life time situation that Inventories are progressively larger moving backward through the supply chain. 

Consequences: 
In addition to greater safety stocks, the described effect can lead to either inefficient production or excessive inventory as the producer needs to fulfill the demand of its predecessor in the supply chain. This also leads to a low utilization of the distribution channel. In spite of having safety stocks there is still the hazard of stock-outs which result in poor customer service. Furthermore, the Bullwhip effect leads to a row of financial costs. Next to the (financially) hard measurable consequences of poor customer services and the damage of public image and loyalty an organization has to cope with the ramifications of failed fulfillment which can lead to contract penalties. Moreover the hiring and dismissals of employees to manage the demand variability induce further costs due to training and possible pay-off
