On 1 November 2011 the Auckland Council inherited a complex IT environment that was the result of the amalgamation of 8 different organisations. As a result, the Auckland Council now has to address the challenges related to a multitude of systems serving the same basic purpose but with differing implementations. This challenge is further compounded by the Council's accountability for an efficient management of the IT assets through a value-based capital expenditure plan, while improving on the maturity of its Information Services and the inherited IS architecture. In this talk we will provide details of these challenges and present the current thinking that is addressing the challenges with the consolidation of IS assets, the revamping of the architecture using a balanced Enterprise Architecture-driven portfolio and programme of work and a focus on improving the maturity of the IS organisation. We will also show how this is being effectively done by presenting an example of a consolidation project.
