Q1) Describe the cycle view of the processes within a supply chain.
Answer: The cycle view divides the supply chain into a series of 4 cycles between the 5 different stages of a supply chain. The cycles are the customer order cycle, replenishment cycle, manufacturing cycle and procurement cycle. The customer order cycle occurs at the customer/retailer interface and includes all processes directly involved in receiving and filling the customer. The replenishment cycle occurs at the retailer/distributor interface and includes all processes involved in replenishing retailer inventory. The manufacturing cycle typically occurs at the distributor/manufacturer (or retailer/manufacturer) interface and includes all processes involved in replenishing distributor (or retailer) inventory. The procurement cycle occurs at the manufacturer/supplier interface and includes all processes necessary to ensure that the materials are available for manufacturing according to schedule.
Q2) Which of the following statements about push processes is accurate?
A) They may also be referred to as speculative processes.
B) Execution is initiated in response to customer orders.
C) At the time of execution, demand is known with certainty.
D) They may also be referred to as reactive processes.

Q1) Sketch the generic value chain for a company and briefly describe the contributions of each of its elements.
Answer: The value chain diagram from the text is:
11ea0c5d_5231_abdc_b35c_eb93172e2d0a_TB2979_00
The value chain begins with New Product Development, which creates specifications for the product. Marketing and Sales generate demand by publicizing the customer priorities that the products and services will satisfy. Marketing also brings customer input back to new product development. Operations transforms inputs to outputs to create the product according to new product specifications. Distribution either takes the product to the customer or brings the customer to the product. Service responds to customer requests during or after the sale. These are core processes or functions that must be performed for a successful sale.
Finance, accounting, information technology, and human resources support and facilitate the functioning of the value chain.
Q2) Intercompany scope is broader than intrafunctional scope.
A)True
B)False
