• The PPM Expense report development consists of adding JSP pages to interact with the JSPF code (SQL) that includes parameters to pull the data and then generate/display very professional tabular expense reports using HTML, cascading style sheets (CSS)
• All these projects followed a very light-weight, iterative, software development method, with constant team communication including end-user requirements. These were very dynamic, fluid projects in that user requirements were being finalized only as they were able to use the various application interim releases.
