- 11 - 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 ofPage: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 Next
