At the heart of IR’s business transformation is the replacement of the legacy tax system with a new custom-off-the-shelf solution. IR shares information from this core tax system with other government agencies, software providers, partners and suppliers, which integrate with its systems for the delivery of IR services countrywide. In an increasingly common IT challenge, the systems are being upgraded without interruption to services provided – the equivalent of changing engines on an aeroplane whilst in flight.
IR’s Director of Digital Change Rogan Clarke describes the business transformation as one of the most ambitious he’s ever seen. “IR got into the transformation programme because legacy systems limited our ability to adapt to new policy. At the heart of it, it was decided that if we’re going to change, let’s think big – and IR really did think big. Exceptionally big.”
IR Business Transformation Testing Lead Chris Hourigan points out two essential factors relating to the organisation’s systems: “We operate complex systems engaging with hundreds of thousands of customers across multiple channels. At the same time, the requirement for accuracy is high, so we must execute assurance practices which maintain a level of integrity and consistency for all channels and customers.”
