Program Plan Intro

Given scenario:

• QueVision system is an enterprise Information System (IS) which depends on real-time data that feeds from point-of-sale system.
• It uses infrared sensors to count customers entering the store and checkout lanes.
• It provides feedback by displaying customer checkout time on a screen that should be seen by both customers and employees.
• The store manager receives complaints about the system from cashiers and baggers.
  • The employees requesting the manager either turn off the screen that displays customer checkout time or add more cashiers and baggers to each shift to reduce checkout time.
