　　An organisation is reviewing the way that Information System (IS) projects are accounted for in the organisation. At present the Information Systems department (which undertakes the IS projects) is a non-recharged cost centre.
　　However, the organisation wishes to explore the advantages and disadvantages of other charging approaches.
　　Four approaches are being considered
　　(1)Non-rechargeable cost centre (current situation)
　　(2)Recharged at cost
　　(3)Recharged at a mark up (profit centre)
　　(4)Setting up a separate IS company
　　Required:

　　An organisation wishes to purchase a software package to administer its workflow requirements. It is currently drawing up an Invitation to Tender (ITT) to send out to potential suppliers.
　　Required:
　　(a)Identify and briefly describe the contents of FOUR possible sections of the Invitation to Tender which will be sent to the potential suppliers.(12 marks)
　　(b)Some of the managers are sceptical about the formal drawing up of an ITT. Project manager, Mary Mendes,claims ‘our approach is to select a software package from a well-established software house, show it to the users and convince them that it is what they want. Ours is a much quicker approach than all this formal ITT stuff’.
　　Explain the potential problems of Mary’s approach to software package selection and explain how these are overcome by a formal approach that includes the production of an ITT.(8 marks)
