A major program to redesign the rewards structure of a frequent flyer program was implemented. The challenge was to smoothly integrate eight different front-end systems as well as middleware and back-end structures. A precise test strategy ensured that all relevant business processes and technical workflows functioned flawlessly.
An end-to-end integration test ensured that all systems involved delivered consistent results. The focus was on transparency of the test steps and stable processes, especially in critical phases. The tests were carried out manually and supported by offshore teams. Tools such as BrowserStack (mobile app testing), Postman, Jira, Xray and Confluence were used. Due to the one-off conversion process, test automation was deliberately avoided.
The project was interrupted by the coronavirus pandemic and later continued with new participants. The testers worked with high-level test cases based on experience and exploration, which saved time and resources. A key success factor was the early identification and resolution of potential problems in the team before they escalated. Pragmatic solutions were preferred in order to ensure efficiency and quality.
The successful changeover was business-critical, as the new points system was particularly important for status customers. The tests were instrumental in providing a stable, reliable system that met both business requirements and high customer expectations. The go-live went smoothly and the new program was successfully introduced.
This project shows how essential structured test management is for the smooth implementation of complex IT projects. Thanks to the targeted use of resources, clearly defined processes and an agile approach, the changeover was implemented efficiently and to a high standard.
