A value chain dissects the firm into its value-adding components, including primary activities and support processes. The primary activities of the value chain model are as follows:

a. Inbound logistics

b. Operations

c. Marketing and sales

d. Outbound logistics

e. Service 

Consider a value chain model of an office equipment manufacturer (e.g., photocopiers). For each of the primary activities, discuss a potential audit risk inherent to it, including any accounts and audit objectives that would likely be affected.
