They can set up then and there and get the same look and feel from any PC,\u201d says Hrycyk.\nPart of that desktop toolset is email, which for a highly reactive customer-centric utility like Severn Trent can be business critical. Quest Software signed up to migrate email from Lotus Notes to Exchange and automate user provisioning through its identity management solutions.\nSpeed of response when customers have problems is vital, so there was no room for downtime during the migration.\nAt the bottom of the move is an intention by Hrycyk to improve on opportunities ofcollaborative working for the company\u2019s workforce.\nHe says: \u201cNow that we have virtual desktops, there is a greater opportunity for virtual teams to form. People can work more flexibly to come together to complete a task. Back-office staff sit alongside front-office staff to break down siloes.\u201d\nEmail is the basic building block of this collaborative working environment as with any other workplace, but Hrycyk expects to integrate dedicated shared working applications, and thinks the move to Exchange will allow him to move to hosted desktop applications in a few years, once Microsoft has established a solid cloud offering.
