Download file to see previous pages The project closes with the quality assurance plan that ensures efficient development and use of the resources. This is vital for the development of any system (Systems Development Life Cycle, 2014).
A data flow diagram is well-drawn as it disintegrates the system into smaller parts called processes that characterize the pizza system. Data also appropriately enters the system from an external environment. These data then flows between the processes undergoing processing and then finally the result is produced. The data flow diagram also provides a clear representation of the system. The model starts well with the overall picture of the pizza system and then continues to analyze each of the functional areas of interest. The analysis is carried out to precise the level of details required. The student uses the top-down expansion to accomplish the analysis in the best way possible (“Data Flow Diagram Software”, 2014). A data flow diagram is also simple and straightforward (Kozar, 1997).
The use case diagrams are also excellently constructed. At the initial step, all the top-level behavior have been identified. Details are then continually added to the use case by decomposing the use cases. The use cases are an actual depiction of the system functionality (Heywood).
The functional decomposition diagram also shows on a single page the functions of the system. From this diagram, it is simple to develop the models of the system. (, 2013). Heat maps are also layered on top of the functional decomposition diagrams to show their scope and decisions. The diagrams are linked to other parts of the model to show how the applications support each other hence a comprehensive diagram.
The sequence diagrams models the flow of logic within the system and shows the steps and the interaction between objects. The diagram enables for the documentation and validation ...Download file to see next pagesRead More

Systems Analysis and Design

...Systems Analysis and Design If I were a systems analyst building a detailed test plan, I would use the Software Testing Approach as my main testing strategy. The Software Testing Approach is acquired largely from the Business Requirement Specification record (Shelly and Rosenblatt 502). This strategy is a static record implying that systems do not update it frequently. I would use simulated data in my test plan because it is suitable for testing limited situations within the plan or organization. The data values I use can simulate live information and additionally test limited situations. The most crucial security issues facing organizations today are...
