Client Admine is a B2B marketplace targeted at local and regional advertisers to buy and sell proven and original print, radio and television advertising. Challenge Admine’s goal is to become the first Internet marketplace to offer local and regional businesses instant, on-line access to entire print, radio and TV advertising campaigns for a fraction of the usual cost. Admine had already worked with a couple of other development firms but had experienced significant delivery problems. WebCritical was selected to pick up the pieces, resolve the design and development issues and deliver the final site within an extremely tight deadline. Solution Using our Rapid Application Development methodologies the site was brought under control, developed and delivered in less than four months. WebCritical quickly documented the business, functional and technical requirements for the site. The User Interface was designed to support both buyers and sellers for the submission, selection and purchase of ad campaigns. We created the information architecture and integrated the existing brand identity into the application. WebCritical developed a scalable, real-time database requiring update, search and maintenance features that could support a frequently changing environment and support multiple transactions. The extensive database required multiple search capabilities including 15 industry sectors, license markets by DMA, zip, county and state. Additionally we: Developed credit card processing functionality with CyberSource. Extended site functionality through the use of ScreamingMedia.
