Additionally, the new ordering system should reduce existing expenses associated with the current order processing system.

The new ordering system will require a minimum of 256kpbs between each warehouse and Tokyo. Management has budgeted $250,000 USD for new network equipment and $100,000 per year for circuit costs. XYZFoodCorp’s IT department consists of two technical support technicians who currently have no expertise with networking. The new CTO plans to outsource the design and implementation of the network and hire one new technician to perform network management. XYZFoodCorp’s Management is very concerned with the security of the new application and the new threats posed by connecting the headquarters to the Internet. What major goals does XYZFoodCorp hope to achieve from this project? (Choose two.)

a. Increase market share
b. Roll out a new ordering system
