The goal of the data conversion, cleansing and enrichment approach was to complete and support the data cleansing activities required to convert release data from all our heritage data sources into our new platform START.
The goal included completing and supporting data enrichment initiatives which supported the realisation of benefits from the transformation.
Success required a collaborative and coordinated approach to data cleansing and enrichment across all of Inland Revenue, something which we learnt along the way as the release became more complex.
The willingness of the operations teams outside the programme to support the data cleanse activities contributed significantly to the success of each go-live. Teams from across the customer facing business, from frontline people to legal specialists, did their share of what was termed burndown work. This allowed us to head into cutover with our data in the best shape it could be, which played a major role in reducing risk.
Data governance
All work was overseen by the Data Owners Forum, a data governance group led by a customer segment lead from the business whose membership was made up of representatives from all functional areas within the programme.
