A.T. Kearney Procurement & Analytic Solutions, a unit of the global consulting firm A.T. Kearney, is a leading provider of technology solutions for procurement challenges. While deploying a series of Web-based tools for clients, the unit identified the need for a more effective collaboration mechanism between its consultants and clients. This led to the establishment of a client extranet based on technologies from Microsoft and SharePoint Solutions, a Microsoft® Gold Certified Partner. The use of familiar Microsoft technologies made the extranet as easy for clients to use as it was fast for the unit to deploy. Thanks to the extranet, the unit has increased the range and usefulness of its services, and clients have round-the-clock access to comprehensive and meaningful information.
