Assessment Item 2
Picture this: You and a few friends have just graduated from Charles Sturt University and see in the newspaper the opportunity to submit a tender to build 6 new medical centres. The medical centre is a franchisee of Mediocre Medical Centres. If the tender is successful part of the job will involve designing a prototype medical centre which will consist of 10 consulting rooms, 2 surgery’s, a community health section, pharmacy and a café. The difference in this design is the floor needs to be rotating enabling patients to be moved around without walking.
Your mates are Arty the architect, Doc the doctor, Mark the marketing manager and yourself a management accountant. As a group you work on the tender criteria together.
Question 2 (10 marks)
