Presentation from Service North: SIAM Edition, a conference held in Leeds UK on March 30th 2017. Littlefish and Historic England have both seen a dramatic change as organisations and have been working together in partnership since late 2016 to on-board and run a new SIAM model involving new some insourced and outsourced IT services. They explain how the experience has been from a customer and supplier perspective before, during and after implementation. This includes lessons learned, organisational change and how collaboration, partnership, principles and a twist of DevOps, have helped (or hindered) progress.
