O2’s Financial Data Hub: going beyond IFRS compliance to support digital transformation

O2’s Financial Data Hub: going beyond IFRS compliance to support digital transformation

Thursday, April 19

Room V

In order to support the new IRFS 15 global accounting standards, O2 UK needed a new reliable, robust solution that could also be used to trigger a new wave of transformational activities. The main idea was to ensure that the basics were met by building a centralized, highly reconciled financial data hub that in time could be used to support all financial and additional business reporting.

Requirements from business stakeholders were well defined where the data was to be refreshed daily with yesterday’s data being available by 9 a.m. the following day. Full data lineage must be known and reference data and business rules needed to be automated.

O2 working with its service integrator, Accenture, brought together a team to design and develop a new big data architecture. The overall solution was based on a hybrid architecture, where Big Data Open Source technologies were brought together with Ab Initio to meet the overall requirements.

The Financial Data Hub went live in August 2017 and has ensured that O2 meets its compliance obligations as well as having a hybrid big data architecture built for the future.
