JANET(UK) provides one of the world's leading research and education networks serving 18 million users. Operating as JANET(UK) the company is constituted as the JNT Association, a company limited by guarantee and owned by the four categories of members: the UK higher and further education funding bodies, the higher education institutions and research councils, the further education colleges and individual members. Accountability is derived through an annually reviewed Service Level Agreement with the Joint Information Systems Committee (JISC).There are several reasons why JANET(UK) needed to change. Most critical was the growing pressure to reduce the cost of service provision from both the Government, committed to stringent cuts across public funding, and user institution customers who, in a challenging financial environment, become increasingly discerning in what they require. In response to these shifting market dynamics, JANET(UK)'s CEO, Tim Marshall, was driving the transition from a largely centrally funded model to one where there may be a variety of variable revenue streams.Tim and his team were clear what was needed to achieve this change: understanding and acting upon customer needs through high trust relationships, driving the market through innovation, value-driven partnerships with customers, suppliers and staff and delivery on promises. The Board was equally clear on the essential programmes needed to effect the change, which spanned customer intimacy, product development, delivery processes and culture.A primary component in achieving the shift to a commercial model was the development of a Balanced Scorecard to reflect the new value dynamics, with which to track and correct performance across the company. It was decided to build a Dynamics Model with which to define and quantify the most critical performance measures. The model evolved through a number of workshops with senior JANET(UK) staff.
