Digital Insights: Solution Architecture - Changing systems successfully

In many companies, a necessary but uncomfortable step has to be taken at some point: the replacement of a central system. Perhaps it is technically outdated, no longer maintainable, or simply no longer meets the growing requirements. The decision for a new system is often easier than the path to it — because it is precisely this that is associated with challenges.

Changing systems: more than just a technical project

Changing a central system always entails changes:

• Processes have to be adapted — because a new system often maps processes differently to the old one.
• Users need to be trained — new interfaces, new ways of thinking, new operating logics.
• Connections to other systems need to be reworked — data flows, APIs and interfaces rarely play along “just like that”.

These challenges often lead to project delays, uncertainty within the company and a temporary drop in productivity. This is precisely where we come in with our agnostic solution architecture.

Why solution architecture is the decisive success factor

Our task as solution architects is not just to select a new system, but to design a sustainable and future-proof architecture that is tailored to your goals and framework conditions. In doing so, we not only consider the system to be replaced, but also the entire system landscape and its long-term orientation.
Our consulting approach is agnostic, i.e. we do not select technologies, platforms and tools according to preference, but according to suitability — always with regard to:

• Your existing infrastructure,
• Your operational requirements,
• Your long-term business goals,
• your budget and your timeline.

Modern architecture paradigms for more flexibility and future viability

The choice of the right tool or system is not the only decisive factor in a system change - the architecture of the new system is also of central importance. We rely on modern architectural approaches that help companies to remain flexible in the future:

Best-of-breed approach

Instead of using a single system for everything, we rely on the "best-of-breed" approach, in which the best solution is selected for each problem. This allows each system to play to its strengths without having to compromise on functionality.

Microservices architecture

With microservices architecture, the application is divided into smaller, independent modules. These can be developed, deployed and maintained independently of each other. This enables a high degree of flexibility and scalability. This means that future adaptations and extensions can be implemented more quickly and cost-effectively.

Headless approaches

Headless architectures separate the backend logic from the user interface, which enables greater flexibility in presentation and interaction. This approach allows companies to operate different front ends (such as apps, web portals or IoT devices) independently of the back end. This simplifies future expansions or the replacement of systems or tools.

Step-by-step transformation: modular approach for sustainable results

A system change is a long-term process, and we recommend taking a step-by-step approach. Replacing a central system does not always have to be a “big bang”. Instead, a modular approach can help to minimize risks and ensure continuous improvement.

• Module by module instead of a one-off major conversion: By implementing new modules step by step, existing systems can remain in operation while the new solutions are integrated. This enables a smooth transition phase without major downtime.
• Methodical consulting for sustainable transformation: We offer not only technical expertise, but also methodical support for the implementation of the system change. This includes project management, change management and advice on organizational adjustments. We help you to make the change sustainable and efficient so that your employees adopt the new solutions quickly and easily.

From a patchwork quilt to a strategic system landscape

Even if the system change initially seems like an isolated project, it creates enormous added value in the long term:

1. Increased efficiency after the changeover
   After a short familiarization phase, processes usually run leaner, more stable and more automated — often with a better user experience.
   
   
2. Future-proof thanks to modern interfaces and standards
   New systems usually rely on open APIs, cloud capability and modular architectures. This not only facilitates the current project, but also future integrations.
   
   
3. Gaining experience within the company
   Once you have successfully replaced a complex system, you can approach the next replacement with clear processes and more security - change management becomes a skill.
   
   
4. More flexibility through strategic architecture thinking
   This metaphor sums it up well: in modern architectures, you "pull a plug" instead of cutting a “branched network of cables”. Targeted modularization makes the IT landscape more adaptable.
   
   

Our role: Enabler for sustainable digitalization

At basecom, we don't see solution architecture as pure IT design, but as a translation service between business, technology and organization. Our goal is to work with you to create a technological foundation that not only works today, but also thinks about tomorrow.
Whether you want to modernize individual systems, automate processes or strategically develop your entire IT landscape — we will accompany you along the way. With a deep understanding of technical realities, clear communication with stakeholders and a view of the big picture.

Conclusion: system change is an opportunity for the future

System changes are not risks, but opportunities that make companies competitive in the long term. With the right planning, architecture and agnostic advice, the path to this goal can not only be made more secure, but also strategically sensible. We help you to make your systems fit for the future — with a clear focus on flexibility and modularity for a sustainable transformation.
