Was bedeutet Softwaremodernisierung?

Softwaremodernisierung bedeutet, eine bestehende Anwendung gezielt technisch oder strukturell weiterzuentwickeln. Dabei muss nicht automatisch alles neu gebaut werden. doubleSlash prüft deshalb zunächst, welche Geschäftslogik erhalten bleiben sollte und ob Weiterbetrieb, Modernisierung oder Ablösung wirtschaftlich sinnvoll ist.

Wann sollte man ein Altsystem ablösen?

Eine Ablösung wird sinnvoll, wenn Architektur, Technologie oder Abhängigkeiten die nächsten geschäftlichen Anforderungen nicht mehr wirtschaftlich tragen. Das lässt sich nicht allein am Alter festmachen. Deshalb vergleichen wir Weiterbetrieb, Modernisierung und Ablösung anhand Ihrer konkreten Anwendung.

Was kostet die Ablösung eines Altsystems?

Die Kosten hängen vor allem von Geschäftslogik, Daten, Schnittstellen, Dokumentation und Anforderungen an den laufenden Betrieb ab. Das Assessment schafft zunächst einen belastbaren Scope und eine Aufwandsspanne. Ein konkretes Umsetzungsangebot folgt erst danach.

Kann das Software-Assessment auch den Weiterbetrieb empfehlen?

Ja. Weiterbetrieb ist ein vollwertiges Ergebnis, wenn die Anwendung ihren Zweck weiterhin wirtschaftlich und verantwortbar erfüllt. In diesem Fall benennen wir die Maßnahmen, mit denen Sie Betrieb und Wissen absichern.

Ist eine Altsystem-Ablösung zum Festpreis möglich?

Ein Festpreis ist für einen ausreichend geprüften und klar abgegrenzten Scope sinnvoll. Das Assessment schafft dafür die Grundlage. Ob Festpreis und verbindlicher Termin angeboten werden können, entscheidet sich anhand der konkreten Anwendung und eines Delivery-Commitments.

Müssen für das Software-Assessment Quellcode und Dokumentation vorliegen?

Für eine belastbare Bewertung benötigen wir ausreichenden Zugang zum System und zu seinen Abhängigkeiten. Fehlende Dokumentation schließt ein Assessment nicht automatisch aus, beeinflusst aber Prüfumfang, Aussagekraft und Aufwand.

What does software modernization mean?

Software modernization involves the targeted technical or structural enhancement of an existing application. This does not necessarily mean that everything has to be rebuilt from scratch. doubleSlash therefore first assesses which business logic should be retained and whether continued operation, modernization, or replacement makes economic sense.

When should you replace a legacy system?

Replacement becomes a viable option when the architecture, technology, or dependencies can no longer support future business requirements in a cost-effective manner. This cannot be determined solely by age. That is why we compare continued operation, modernization, and replacement based on your specific application.

How much does it cost to replace a legacy system?

The costs depend primarily on business logic, data, interfaces, documentation, and operational requirements. The assessment first establishes a reliable scope and an estimated range of effort. A concrete implementation proposal is provided only after that.

Can the software assessment also recommend continued operation?

Yes. Continued operation is a valid outcome if the application continues to fulfill its purpose in an economical and responsible manner. In this case, we will outline the measures you can take to ensure continued operation and preserve knowledge.

Is it possible to replace a legacy system at a fixed price?

A fixed price makes sense for a scope that has been sufficiently evaluated and clearly defined. The assessment lays the groundwork for this. Whether a fixed price and a binding deadline can be offered depends on the specific application and a delivery commitment.

Is source code and documentation required for the software assessment?

To conduct a robust assessment, we need sufficient access to the system and its dependencies. A lack of documentation does not automatically preclude an assessment, but it does affect the scope, validity, and effort involved.

Modernizing Software: Making the Right Decision

ASSESSMENT OF EXISTING SOFTWARE

Make Clear Decisions. Implement Them With Confidence.

Request an Assessment

Your existing application contains valuable business logic and supports core processes. Through targeted modernization, you can lay the foundation for faster further development, stable operation, and new digital opportunities.

The right approach depends on your specific situation. That’s why our software assessment compares continued operation, modernization, and replacement. You’ll receive reliable scenarios for effort, duration, and risks –, and, if you wish, we’ll support you all the way through implementation.

Neutral & unbiased: We recommend the approach that makes the most sense from both a technical and economic standpoint.
Tailored to your existing systems: For off-the-shelf software, custom software, portals, and departmental solutions.
Thought through all the way to implementation: Aclear starting point, a reliable roadmap, and experienced engineering.

Get More Out of Your Existing Software

We assess the potential of your existing software and determine which approach will most effectively expand your scope for action: targeted security measures, modernization, or a controlled phase-out.

Implement changes more quickly: New features and requirements are rolled out into production faster and in a more controlled manner.
Make operations predictable: A stable technical foundation facilitates releases, support, and secure further development.

Embedding Knowledge in the Team: Documented business logic spreads system knowledge and reduces dependence on individuals.
Use the budget more effectively: Prioritized measures direct investments toward the greatest business and technical leverage.

YOUR DECISION-MAKING PROCESSES

Should We Modernize, Replace, or Continue Using the Software?

Software modernization enhances existing applications without having to rebuild everything from scratch. For business-critical legacy systems, this is often referred to as legacy modernization. We’ll determine whether this approach offers the greatest benefit for your application during the assessment. To do so, we’ll compare continued operation, modernization, and replacement based on technical, economic, and organizational criteria.

Continue Operations and Implement Targeted Safeguards
The application continues to serve its purpose. Specific measures safeguard knowledge, operations, documentation, and technical dependencies.

Modernize in stages
Valuable business logic is preserved. Critical technologies, modules, interfaces, and user interfaces are updated in a targeted manner.

A Controlled Transition
When the existing infrastructure can no longer support operations, a realistic path for migration or a new build becomes available. Data, integrations, and ongoing operations are taken into account from the very beginning.

Here's How We'll Work Together to Move Your Software Forward

Our software assessment is technology- and industry-neutral.

We evaluate your software within the context of specific business processes, identify valuable business logic, and determine how it can be preserved.
