Developers Under Stress:
The challenging legacy of legacy applications – Refusing the „inheritance“ is not an option!

Legacy applications on IBM Power i (AS400) or IBM Z (mainframe) - often still written in COBOL, PL/I, RPG or Assembler - need to be kept running and should be modernised or replaced. The weight of the task is placed on the employees in application development and IT operations. And the experts in legacy applications and technologies are becoming fewer and fewer due to retirement. Although these are business-critical applications, too little is being invested in them because decision-makers underestimate the challenge and focus on other hype topics. Read how you can remedy this situation with tool-supported code analysis and which innovative features of eXplain, the leading source code analysis tool from PKS, you can use to do so.

Get the best toolbox for your difficult task with eXplain and show your boss that you know how to gain transparency and control over legacy applications! With the right approach, you will also convince decision-makers that it is worthwhile to lead the legacy transformation to success systematically and with the right resources.

In this white paper you will learn:

All about code analysis, clustering, quality assessment and job net visualization

Functional scope and use cases for eXplain

Application examples and experiences of other companies

All the advantages of an innovative approach that will also convince your superiors

With eXplain from PKS, we were able to identify a significant portion of unnecessary code in our Natural and COBOL-based core banking system, thereby fundamentally cleaning up and streamlining the system. The fully automated documentation generated by eXplain also comprehensively meets our audit requirements. These are just two examples of how eXplain supported us in our „Core Banking System Stabilization“ project. I would particularly like to highlight the extremely pleasant collaboration with the competent PKS team and the flexible project options, which allowed us to always accommodate Helaba-specific requirements.
