process of designing and implementation alone would be harder because one critical error in one of the phases can cause multiple phases to be canceled, or redone. N. Suppose you are an analyst working for a small company to develop an accounting system. What type of methodology would you use? Why?If I were an analyst developing a methodology to use for an account system, I would still use the waterfall based method. As mentioned earlier, account in general deals with numbers, balance sheets and income statements and equity. Since each phase in account normally requires the previous to be competed to move on to the next, establishing a system where all steps are to be completed one by one before proceeding to the next is crucial for most account processing systems. The waterfall based method for these systems would be beneficial as it would encourage extensive and thorough analyzing before concluding to the next step .O. Suppose you are an analyst developing a new executive information system intended to provide key strategic information from existing corporate databases to senior executives to help in their decision making. What type of methodology would you use? Why?
As an analyst, if I were to develop an information system that would provide information from databases to senior executives, then the Unified Process is the way to go. Since this is object oriented, RUP method can allow me to test the software, then go back and make changes. I would also have the freedom to go back redesign if necessary, or even if I needed to go back to analysis phase, it would be no problem. An issue I would note though is that with RUP methodologies, one phase is not elaborated over another; in other words, the entire development process will be left unorganized. Also since this is a big project, multiple development process can lead to more confusion and can result in more errors being made. P. Investigate the Unified Modeling Language on the Web. Write a paragraph news brief describing the current state of the UML. (HINT: A good website with which to begin is .)When analyzing systems, UML helps greatly in visualizing, specifying and documenting models.
