Week 4 Assignment 2: Use Cases
CIS 210: Systems Analysis and Development November 3, 2013
A use case with typical and alternate courses that documents the event of a bank customer withdrawing money from an ATM. In this particular use-case scenario a system analysis will be identified when a bank customer interacts with an ATM to withdraw money. Typical and alternate courses will be identified. A use-case diagram will be used as a tool to provide clarification of the necessary components or processes including hardware, system software, process and human interaction to layout or plan and identify the various components necessary to produce the desired session outcome. Rouse (2007) describes the use-case methodology; “A use case is a methodology used in system analysis to identify, clarify, and organize system requirements. The use case is made up of a set of possible sequences of interactions between systems and users in a particular environment and related to a particular goal. It consists of a group of elements (for example, classes and interfaces) that can be used together in a way that will have an effect larger than the sum of the separate elements combined. The use case should contain all system activities that have significance to the users. A use case can be thought of as a collection of possible scenarios related to a particular goal, indeed, the use case and goal are sometimes considered to be synonymous.” In this project a use case methodology will be used to illustrate the required elements to successfully plan and implement a system that will allow a user to make a withdrawal from their banking institution and have all the necessary components interact in such a way as to successfully track the transaction and allow the user to make the transaction without error. A typical course of action would be…...
