Using these data and certain DIES models, market analysts at Glaxo were able to track and size the sources of demand, generating summary reports and projections in minutes. The projected demand was fed into the D53 models to figure appropriate production plans, delivery schedules, and inventory levels along the supply chain . As a result ._ Glaxo streamlined its distribution process so that wholesalels and retailers around the world seldom ran out of the drugs. An added benefit was that operational costs were reduced. Finally, the system provided Glaxo's employee s with a tool that allowed them quickly and easily to access information from different sources.
