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’.
