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 ivetigatesany current system, identifies . (71) and develops a concept for the new system. This phasehas three steps: first, . (72) is developed to guide the project team's efors. It usuallyincludes an analysis of the current system and its problems, and the ways to design a newsystem. The nextstep is _(73)_ . The analysis of this information in conjunction with inputfrom the project sponsor and many other people . leads to the development of a concept for anew system. The system concept is then used as a basis to develop a set of business analysismodels that describes how the business will operate if the new system were developed. The setof models typically includes models that represent the  (74)necessary to support theunderlying business process. Last, the analyses, system concepts, and models are combinedinto a document called the (75) , which is presented to the project sponsor and other keydecision makers that decide whether the project should continue to move forward.
