               E.  Phase 5:  Physical Design                                          
               In the physical design phase, which is sometimes referred to           
          as the technical design phase, the technical solution to the                
          business problem described in the logical design phase is                   
          determined.  The technical approach to building the system requires         
          consideration of the interfaces; that is, how the software operates         
          in conjunction with other applications or systems.  During this             
          phase, the tools for building the system are described, as well as          
          the nature of the interfaces between the software and other                 
          systems, the estimates of volume that requires processing, and the          
          timeframe for processing.                                                   
               F.  Phase 6:  Development                                              
               In the development phase, physical system components are               
          constructed, documented, and verified.  During this phase, the              
          programmers write the source code that will allow the computer to           
          perform the required tasks, and initial plans are made for testing          
          the software.                                                               
               G.  Phase 7:  Testing                                                  
               In the testing phase, the technical development portion of the         
          project is completed.  During this phase: (i) Unit testing is               
          performed to determine whether the individual components of a               
          system are technically ready for production, (ii) integrated                
          systems testing is performed to determine whether all components of
