Result
The platform has been implemented successfully. All required data is stored on the cloud platform and is available for insight and analytics, and because data is also stored in its raw form, it can be used for other future purposes. The software services have been delivered successfully as well in several releases; the design and development know-how are continuously shared with the client. Furthermore, the test framework is successfully used within the company to test their software automatically
