Quality Assurance and Data Integrity for the new Application "ZLPro" (AZL, Department for additional contributions to retirement provisions of the City of Zurich)
In a classic end-of-life project, the existing application had to be replaced by a modern solution.
The new application for processing investments, payment initiation and bookkeeping must fulfill various critical requirements: system stability, usability and (processing) quality are just some key figures.
As a public office with a major economic responsibility (annual cash flows in the high nine-figure range), AZL is highly exposed and therefore has a very high demand on the quality of the processing and the control of the cash flows.
Hence the quality assurance in the transition phase (parallel operation) from the existing to the new solution was of great importance in this project.
OMrun was used as a quality gate and final control instrument: with OMrun, all data products and key figures identified as critical for success between the legacy system and the new building were compared, rule-based and workflow-controlled. Only after all defined go-live measuring points published in OMdashboard turned green, the final go-live decision was made.
In the operation of the new ZLPro application, which was awarded a "Best of Swiss Web 2018" award, OMrun is part of the infrastructure as a permanent data integrity and data quality monitor and serves the responsible persons as an actual early warning system.
As a data governance tool, OMrun ensures that any rule violation - caused for example through hot fixes, due to legislative changes or planned release updates - are immediately displayed. The list of rule violations can then be analyzed by the specialists and passed on to the development department for correction. This itarative process is repeated eternally, causing only little maintenance effort, because we all know: after the system changeover is before the system changeover...
