The Data Migration Test Team was struggling to keep pace with the delivery of new and updated pLDM and volume of data which was being migrated and transformed. We were tasked with implementing a mechanism to assure that the migration and transformation of data had quality gates and assure that the data transformation rules had been thoroughly tested. The goal was to assure the data was available in a correct format and location in the target database.
The health service customer is a central player in the UK health sector and is undergoing an internal transformation to one of its backbone applications. Testing had become inconsistent and caused a bottleneck when faced with the mass of coverage required to deliver confidence to stakeholders that the transformation process was implemented correctly. The Data Migration Test team’s approach had, therefore, become a risk to the project.
