Why Modeling?

Why Modeling?• Modeling will:

– Captured and simplified requirements– Visualize the entire systems and process in an easy to understand

diagram

– Specified the process, features, or functionality of the entire systems

• Eventually, modeling will:– Sharpen user understanding on fundamental processes

– Allowed user to compare alternative

– Help to make decisions and improve system behavior

– Provide a guidelines for future enhancement

– Reduce unnecessary risk.

ScenarioScenario 1• Your team has been hired as software integrator to provide an application that stores various substations

documents in a server. The application shall have at least two type of users of which one type of user is allow accessing all applications features whereas the other user is allow to access limited features. The application shall be able to store documents, perform folder and document manipulation (print, upload, download, etc). You are required to perform business analysis and create at least one of UML diagram.

Scenario 2• Your team is required to perform analysis and design a system that able to interrogate primary and

secondary equipment’s condition (including health, status, and performances) in a substation. Perform business process analysis and using Enterprise Architect to design UML diagram that will explain the detail of the process, activities, and entities involves in the system.

Scenario 3• A new application that runs on web is required to enable engineers to perform analysis on fault and

disturbance records. The applications shall be able to download complete records automatically upon engineer click on the fault information display on the screen and shall be automatically display the wave signal captured in the recorded files. The application shall allow user to perform analysis such as fault identifications, fault locations, etc. Your team is required to design a UML diagram to describe the overall process or activities that will be implemented in the applications.
