Identifying High-Level Requirements

The requirements use case descriptions are not very specific. There are a number of areas where we've identified requirements but not specific functionality. For example, some of the requirements we can derive from the video rental use case could include:

• The store maintains an inventory
  
  
• The inventory must be available for browsing
  
  
• The store employs an attendant
  
  
• There is a mechanism by which the attendant can identify a specific customer
  
  
• The attendant can identify specific videos
  
  
• There is a security system triggered by videos leaving the store
