The challenge

Legacy systems are the unsung heroes that are driving your organization’s achievements. They are the foundation of your success, containing essential domain knowledge and unique processes, which unfortunately are not always properly documented. However, the high-tech world is moving forward at a high speed. Therefore, systems need to do more than just exist and function in their original form. They must be adapted, expanded and transformed to meet the demands for the next generation platforms.

Continuously maintaining and evolving the software of existing machines within your portfolio presents significant challenges on many fronts. It can put a big strain on resources – time, budget, people involved and domain knowledge. In addition, there are technical hurdles, including outdated technology, scarce documentation, security risks and challenges related to domain knowledge that may have left the company. Addressing this complex topic creates the urgent need for modernization and strategic solutions.

In today’s dynamic high-tech market, standing still means falling behind. Innovation, agility and swift response to emerging demands and requirements are paramount. Legacy systems that once drove progress, can now limit or even stagnate growth. Modernization ensures improved efficiency, cost reduction, optimization of expandability and obsolescence management. This forms the foundation for future product releases and prevents potential disqualification. Sioux helps you achieve these goals.

The solution: System evolution through module revolution

Legacy systems are typically monoliths; highly complex, intertwined, and inflexible software components based on old concepts and dependent on outdated tools. Sioux has developed a unique approach to ease the maintenance and modernization of these systems and uses a practical incremental process of continuous improvement and innovation. This approach is called “System Evolution Through Module Revolution “, and it empowers us to transform your legacy systems into a manageable state.

Services

Sioux can act as an extension to your R&D department and provide excellent aftercare over the entire lifetime once your product is on the market. In addition, we provide the tools to customers that enable them to continue to make modifications at the same level of abstraction.

Assessment, identification and prioritization
The Sioux Brownfield project starts with an assessment of the current situation: What is the current status, what is already in place, what are the dependencies? Then we look at where you want to go and what the criteria are to meet the current and future demands. Key pain points are identified and prioritized, and a plan of action is put into place. A small adjustment in the existing software can already be sufficient to achieve the goal. If a more radical step is required, we tackle this incrementally in order to be able to validate the correct functioning of the software at any time.
Isolate hot spot (problem) modules
When a software system’s maintainability is too low and a system revolution is needed, the next step is to isolate the software modules that need urgent attention. Sioux recreates an orderly layered architecture, including corresponding interfacing. This way, intervening in the hot spots does not affect the functioning of the entire system. This allows us to realize the necessary modernization work in parallel with the ongoing work.
Greenfield approach
When new System Control Software needs to be developed, Sioux utilizes on its proven solution for Greenfield System Control Software. This entails, among other things, a model driven approach to code generation, digital twinning and the use of Sioux assets and reference architecture, alongside an improved testability. This results in high quality, cost efficiency, speeding up development and adaptability for future upgrades.
