The analysis phase answers the questions of who will use the system，what the system will do，and where and when it will be used．During this phase，the project team investigates any current system，identifies (71) ，and develops a concept for the new system．This phase has three steps：first， (72) is developed to guide the project team’s efforts．It usually includes an analysis of the current system and its problems，and the ways to design a new system．The next step is (73) ．The analysis of this information-in conjunction with input from the project sponsor and many other people-leads to the development of a concept for a new system．The system concept is then used as a basis to develop a set of business analysis models that describes how the business will operate if the new system were developed．The set of models typically includes models that represent the (74) necessary to suppor the underlying business process．Last，the analyses，system concepts，and models are combinedin to a document called the (75) ，which is presented to the project sponsor and other key decision makers that decide whether the project should continue to move forward．

A．improvement opportunities
B．logical model
C．system requirements
D．system architecture
