Application Architecture and Process Design
Identifying the discrepancies and shortcomings of our previous system proved much easier than developing the application architecture and process design of the proposed system. According to the National Institute of Open Schooling, the next step following the initial study was to test the feasibility of the new system. This step included verifying that the proposed process met the needs of the organization, was cost effective and that the process made effective use of company resources, to include people and equipment. "The main goal of feasibility study is not to solve the problem but to achieve the scope."

During the feasibility analysis, we identified which of our current resources could be utilized during the implementation of the new process. We researched the capabilities of our current infrastructure to determine if our network, peripherals and servers could support our proposed solution. This analysis showed that additional hardware, software and connectivity would be required. Although a preexisting intranet was in place, we determined that the load and network traffic that would be produced by the new process 's extensive data transfer warranted a dedicated system. The backbone of the new system was comprised of a new HP ProLiant DL580 G3 Server. According to Hewlett-Packard, the new server 's dual Xeon Processor and 6 gigabytes of read only memory (RAM) would provide sufficient power to support the requirements of the new system. The DL 580 's Integrated Smart Array would also provide ample storage with the capability to house up to 1.2 terabytes (TB) of internal storage. (Hewlett-Packard Development Company, L.P. 2006) In addition to the hardware, additional licensing was required for both Windows 2003 Server Enterprise and Microsoft SQL Server. An additional HP ProLiant DL380 G4 Server was also required to support the Linux based Docutron system (www.docutronsystems.com) that would be responsible for storing and
