Fiserv first encountered Fresche’s X-Analysis documentation tool while working with one of its clients and was impressed by the tool’s flexibility, ease of use, and reputation as the leading IBM i modeler on the market. When Fiserv decided to document its core banking engine, which is used by almost 300 financial institutions to deliver integrated banking and data warehousing solutions, X-Analysis was the logical choice, says Carol Cowen, Fiserv’s Vice President of Marketing and Strategic Business Growth.

Challenge

Fiserv Inc is a leading global provider of end-to-end business and technology solutions for retail financial organizations, consumer finance institutions, and credit unions. The advancement of technology began to place pressure on the static documentation process, and the need for comprehensive and flexible documentation became critical.

Solution

With Fiserv’s RPG code documented and kept up-to-date in the X-Analysis data repository, solving problems or adding functionality became much easier. X-Analysis combines highly detailed crossreferencing with high-level analysis and documentation in a single product, making it the ideal tool for IBM i application design recovery, analysis, and documentation. Some of the advantages of the tool include data modeling, structured English source code views, application subdivision, static project document wizards, data analysis, and business rule logic analysis. Fiserv programmer Malcolm Sharp was particularly impressed with the tool’s easy-to-use and highly interactive graphical structure, which lets both IBM i programmers and those with little or no programming knowledge use the tool, a feature that distinguishes X-Analysis from other programmer-oriented tools and standard IBM i cross-referencing features. In addition, the tool is capable of accurately documenting even the largest systems and now functions as a plug-in to WDSc and other Eclipse-based editors.

Results

Once the RPG code of Fiserv’s application was documented and kept up-to-date in the X-Analysis data repository, solving problems or adding functionality became much easier.

 

“Fiserv’s experience with Fresche’s support team has also been phenomenal”, says Rohit Patel, Fiserv’s Vice President of iSeries Technical Development. “Fresche is extremely receptive to questions and suggestions and helped Fiserv modify the tool and configure the system to do exactly what the company needs. Fresche was willing to bend over backward for us,” Sharp adds.

 

X-Analysis has helped Fiserv enhance productivity and understanding of its core banking application environment and is now a standard part of Fiserv’s development process. Fiserv’s customers have also benefited by the company’s increased awareness, which has resulted in faster development time and problem determination and has also let Fiserv add valuable technical documentation to its product. “From Fiserv’s perspective, the use of X-Analysis has been a smashing success,” says Carol Cowen.
