The developer who knew everything is gone. Your software is running, but nobody knows how much longer. Many SMEs are stuck with systems that nobody understands anymore. A failure? Would paralyze everything.

Are you looking for a software development partner in Switzerland who specializes in software reengineering? soxes analyses, optimizes and modernizes your software. Our customers benefit from more than 24 years of experience in modernizing software solutions.

Don’t wait until the next failure hits you. Let us analyze your legacy software.

What is software re-engineering all about?

Software re-engineering is the structured process of technically and conceptually revising existing applications without developing them from scratch. The aim is to transform outdated, difficult to maintain or poorly documented systems into modern, scalable and future-proof solutions.

Code, architecture and functions are analyzed, optimized and, if necessary, restructured so that central business processes remain reliable in the long term.

We offer solutions for your problems.

Your technology is lagging behind, performance is suffering and knowledge within the team is being lost - do you want to future-proof your company and make progress in the area of digitalisation?
Your standard software cannot be customised to your specific requirements - do you need more flexibility?
In your company you lose too much time with inefficient processes and outdated software and you want an efficient software solution from A to Z that covers all important processes?

How do companies benefit from software reengineering?

Re-engineering applications is much more than just software maintenance. Through software re-engineering and digitization of processes, companies regain the upper hand over their systems.

The goal of reengineering is to ensure the software quality and its maintainability for a company in the long term. A Refactoring describes likewise quality-improving adjustments of a software, however on operational and rather short term level. A software Reengineering can contain Refactoring measures.

Re-engineering vs. new development

Re-engineering	New development
Optimizing and modernizing existing software.	Design and develop a completely new application.
Less expensive as existing components are used.	Higher investment due to completely new development.
Less time required as many structures are retained.	Less time-consuming as everything is created from scratch.
Lower technical risk because familiar processes and functions are retained.	Higher, as everything has to be retested and integrated.
If core functions are to be retained but need to be modernized.	If the existing solution is outdated, inefficient or unusable.

3 common reasons that speak for software reengineering

Is one of your legacy systems keeping your company on its toes? Software systems may be candidates for reengineering for reasons including the following:

Outdated technologies: Resulting lack of patches can lead to security vulnerabilities.
Loss of know-how: The company does not (or no longer) have the necessary expertise (e.g. programming language) to maintain and operate the software.
Expansion of an existing application: The requirements for an application change. In order to meet the new requirements, existing hurdles or weaknesses of the existing application must first be eliminated.

Our approach to software reengineering projects

Thanks to years of experience, re-engineering at soxes is approached with a proven Methodology.

First, the existing software (legacy software) is analyzed:
Based on the analysis, approaches to improve the software system are designed. Changes and restructurings are examined in detail.
The revision of the system is then carried out in the usual manner of software projects. The implementation of the revised software takes place only after extensive testing.

To what extent can software be modernized?

Reengineering can affect an entire software application or only selected software components. At soxes, experts analyze, evaluate and modernize your applications and show you ways to improve architectures with re-engineering. With architecture adaptation, modernization and process digitization, soxes creates security and opens up new integration possibilities for companies.

Robert Schmuck, CTO soxes

Modernizing your legacy software through re-engineering optimizes your IT infrastructure and at the same time increases the efficiency and competitiveness of your company. All without throwing proven processes overboard.

A practical example:

For a customer, soxes migrated a customer service application from the outdated programming language Delphi to the modern alternative C# in combination with .NET. Subsequently, the functionality of the software could be improved: Thanks to the reprogrammed centralized management of the database, the local installations of the software now draw their information from a single SQL Server database.

Modernizing legacy software at an early stage pays off

Outdated software can initially “only” lead to compatibility problems and instability. In a further step, they often entail high costs in maintenance and operation. In addition, they can also represent a significant security risk for your company and not only a danger to smooth business processes, but also to your data.

The sooner you address the problem, the cheaper it will be for your company to maintain the old system until it is modernized or replaced by a completely new system.
