ABS 2000 – O2K –Work Order TDS Improvement:
Developed and Maintained Enterprise (J2EE) Application for to indicate which surveyors have been trained and who trained them. It will also provide clarity on why someone is listed as a trainee/observer. The reports that are generated will also satisfy the objective of “explicit approval” meaning the trainer, trainee and reviewer will all be involved in the training process. The new TDS system will explicitly detail who trained a surveyor. Trainees will be provided with a UI that will allow them to mark which process codes they have completed. Trainers can review this page and sign-off with their approval. When a reviewer signs off on the final work order they will see a pop up summary view of the surveyor’s qualifications. This summary view will list why a trainee is not eligible for credit and will detail training counts if a surveyor is eligible. The surveyor certification report will be modified to include a new column with the trainer’s name and this report will be sent to the training development system. This application will use Java Class as controller and EJB Beans, Data Writer and DAOs (Java helper classes) for data manipulation, Servlets, Java Helper classes and JSP for presentation layer.
Responsibilities:
• Understand User Specification Requirements Analysis Creating use cases and detailed design. Creating interaction and class diagram. Designing interface using MVC design pattern. Capturing business logic in form of Java beans.
