Suffolk CC and Mid Suffolk DC are to embark on a customer service contract with BT and CGI Group Inc.

There will also be a single point of access for health and social care, a short and simple list of telephone numbers, and a fully transactional website.
The deal is also the first to bring in a dedicated change management consultancy as a strategic partner, CGI. While BT provides the technology, and some change management expertise, CGI will deal with the detail of cultural change to ensure the new systems are embedded in working practices.

who live alone and depend on us for support. I know how frustrated they are when they go to our offices and are told the services they need are not handled there.
'The joint venture is all about becoming more customer-focused.'
