The document summarizes a case study where a luxury retail company needed to upgrade its contact center software before the busy holiday season. The company's existing workforce optimization (WFO) vendor was unable to complete the upgrade on time. Dimension Data, the systems integrator working with the retail company, recommended Calabrio as an alternative. Senior Calabrio executives then met with the retail company and Dimension Data to assure them Calabrio could complete the WFO implementation within the tight deadline, avoiding potential problems during the crucial holiday period. Calabrio was able to deploy the new WFO system across 329 agents within 28 days, meeting the retailer's requirements before the start of the holiday season.
