Why was the quality of the data poor?: Validation

The amount of validation on fields was an issue that continued to be debated. The amount of validation in phase I meant that data loading and correction was more time-consuming than it needed to be as some fields could not be amended by underwriters (00644, 00609, 00689) resulting in the development team being asked to amend data (00903). In phase II some of the controls were relaxed allowing underwriters to save in the middle of a transaction but the data audit revealed that this led to more errors (00754) and a decision was taken to tighten up further on validation (01089).
