- 21 - were developed. Another problem that arose was the development of a so-called pointer system which allowed the end user to access information about a customer through one of various identification sources (e.g., name, account number, Social Security number, etc.). The pointer system was one of the more critical functions of the SBS software. Many of the problems were reviewed and corrected during the testing phase by Norwest technical staff, who would inform EDS personnel of the problems and recommend corrective changes to the software. (A small group of programming experts was assembled specifically to handle the SBS problems through the use of a specialized case tool called PACBASE, which was selected by EDS.) Norwest employed a repeatable testing process to isolate problems and find solutions.12 A running list of these technical problems was maintained in a system provided by EDS. Not all problems were resolved in this process, and often new problems arose from the correction of old ones. Some of the problems that arose in the development of SBS were attributable to poor programming and the 12 This was a particularly difficult process because three different entities were working on the development of SBS. Norwest had to reconcile all of the changes and discover the source of the problems. This process required the isolation of each change made by each entity for testing purposes. Often the attempts to correct one set of problems created new ones.Page: Previous 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 Next
