Software analysis and migration: Success strategies from the field

The first impression counts

A successful software project begins with a clear analysis of the current situation. In an example project, which included a ticket store for local public transport, the software was introduced without detailed knowledge of the code base that had been adopted. It was therefore necessary to first gain a rough overview of the system. By providing experts to analyze the code base, it was possible to determine whether the system was at all viable and maintainable. There were numerous surprises and ambiguities in the code, which made the start of the project more difficult.

Automated analyses as the key to success

Automated tools such as SonarQube played a central role in analyzing the code quality. Static analyses provided valuable insights into the maintainability, robustness and security of the system within a very short time. These tools identified critical weaknesses and provided concrete suggestions for improvement. This made it possible to carry out a well-founded evaluation of the system even under high time pressure.

The challenge of missing documentation

Insufficient or non-existent documentation was one of the biggest hurdles in the project. Some system components were delivered late or were only available as black boxes. This made it considerably more difficult to understand the entire system. However, these hurdles were overcome through close cooperation and clear communication. The team's flexibility and adaptability proved to be decisive factors here.

Agile mindset as a success factor

An agile mindset was essential in order to be able to react quickly to unexpected challenges. Flexibility was required from both the customer and the team. This attitude made it easier to find solutions to problems that suddenly arose and to successfully complete the project despite numerous surprises. The client's willingness to actively participate and apply agile methods also contributed significantly to the success.

Top learnings for future projects

A diversified team setup is a key factor for successful projects. Even if a project seems easy to plan at first glance, there should always be room for adjustments. In addition, testing should never be neglected. A comprehensive testing strategy saves time and money in the long term, as it helps to identify and eliminate weaknesses at an early stage. These findings are essential for the successful implementation of future projects.
