Centralized Software Change Option Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Complex software systems like SAP R/3 require customization and updates, but existing methods for managing change options across multiple systems are time-consuming and error-prone, especially when different systems are affected by different projects, and there is a need to restrict changeability to prevent disruptions in the productive system.
Innovation Solution
A method and system that provide an interface for read and write access to change options in each system, allowing for centralized management of change options across interconnected logical systems through a central control software system, enabling selection of systems based on software service parameter data and managing change options to restrict or allow changes accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If change options are managed manually in each system, then system stability is maintained through local control, but time consumption and error risk increase significantly
Solution Approach 1:
A central control software system is introduced as an intermediary between operators and multiple software systems. This central system manages change options centrally, eliminating the need for manual local configuration in each system while maintaining system stability through coordinated control. The central system acts as a mediator that reduces time consumption and error risk associated with manual management.
2Reliability
If change options are restricted to prevent disruptions, then system stability is improved, but operational flexibility and adaptability decrease
Solution Approach 1:
The system implements dynamic change option management where restrictions are not static but can be adjusted based on system state and operational context. The central control software enables flexible configuration of change options, allowing the system to adapt between restricted and permissive modes as needed, thereby maintaining both stability and operational flexibility.
3Ease of operation
If manual logging and configuration is required for each system, then precise control over changes is achieved, but complexity of operation increases
Solution Approach 1:
Multiple separate control functions for different software systems are merged into a single central control software system. This consolidation simplifies operation by providing a unified interface for managing change options across all systems, while the underlying complexity is encapsulated within the central system rather than being distributed across multiple local configurations.

AI summary
A method for setting change options of software systems of a software system landscape, wherein the systems are interconnected by logical transport paths for the transport of software services therebetween, the software services defining changes to at least one of the code and the data of at least one system, each system having change options that define changeability restrictions pertinent to the system, is described. The method includes providing an interface in each system, the interface allowing read and write access to the change options of the respective system from the outside of the system; providing a central control software system; providing an interface in the central system for communication with the interfaces of the systems; selecting a group of systems based on software service parameter data; and accessing the group of selected systems from the central system via the interfaces and centrally managing a change option in each system of the group.
