| Improving Competitiveness of Proprietary Developments Over Standard Software |
| The Problem |
An increasing number of proprietary developments in RPG and Cobol are being replaced by standard software like SAP. It often only becomes apparent after such a replacement that the familiar functionality and individuality which sets the company apart from the competition is only feasible with standard software or a high degree of effort. The triggering factor lies in (apart from golf-playing managers) the presumption that the existing RPG or Cobol application lacks sustainability.
|
| The Solution |
The application's sustainability should be verified in due time so that no thoughts on replacement arise in the first place. This can be done step-by-step over the course of modernization. With the help of tools, a modern user interface is created, the application is modularized to improve the ease of modifications and make it SOA-capable, and the application is updated.
|
| Procedure |
 Analysis of the application and rough draft of concept with initial cost estimate
Through a transition assessment, an extensive plan including detailed costs is drawn up for  the application's modernization
Through a prototype (proof of concept), the procedure is checked on the basis of a small
part of the application

Reengineering Tools 400
EGL
The reengineering tools 400 EGL break down existing RPG and Cobol applications into their components and extract business rules, data models, etc. in order to reconstruct them in a new and highly agile application architecture based on IBM's Enterprise Generation Language (EGL).
Universal Client
The Universal Client consists of a well-balanced range of various clients for the web, Windows and the green screen, all of which can communicate via the XML standard with migrated apps in Windows, Linux or Unix, as well as the original RPG and Cobol programs in System i.
