Software modernization: When should you replace an old system?
The customer has an older application. It was developed quite a while ago, utilizing outdated technologies and processes. Despite this, it works, and users are satisfied with it—not to mention the established workflows and accumulated data. However, new functionalities need to be added, and security risks are also significant. In some cases, the team (or supplier) responsible for developing the application is no longer available.
How should we proceed? Should we modify the existing application? Or should we replace it with a new one?
What are the options?
Sometimes, starting from scratch is necessary; other times, continuing with existing projects makes sense. At what point do you decide that further modifications to the existing application are no longer feasible, and building a new one is the better option? The decision depends (not only) on your plans for the application.
If the current functionality meets all your needs, maintaining the application in its present state might suffice. However, if you have ambitious growth plans, you need to ensure that the application can support new features that align with your business goals. Additionally, you need to guarantee its operational stability—technically and infrastructurally—and have an operational team and support in place to meet the needs of the business team.
On the other hand, a new application brings new opportunities and technologies. However, implementing and rolling it out will place a significant burden on both your business and IT teams. It will likely involve considerable financial and organizational demands that the organization must be prepared to handle.
How do we proceed?
We analyze. We ask questions. We strive to understand and familiarize ourselves with the current solution. We examine the application’s state, architecture, technologies, and infrastructure. We assess the size and quality of the code and identify its weaknesses. If good and up-to-date documentation exists, the task is more straightforward. Without it, the process is still doable but more challenging.
We evaluate the deployment and operational processes of the application. We engage with the business team to understand their needs, priorities, and experiences. Based on this, we can prepare materials and recommendations to guide your decision on the next steps.
