My last attempt after some time on Google
Order-To-Delivery (OTD): A philosophy that encompasses both Deliver-To-Order and Build-To-Order and thus takes a holistic view of how Original Equipment Manufacturers can fulfill customer orders.
Kumara is working with General Motors' Enterprise Systems Laboratory to develop an Order to Delivery (OTD) simulator system. As the name implies, the OTD allows users to tell the time it takes between order placement and delivery.
"We collected data on how long it takes to put a car out, how long it takes to get to a dealer, and when customers can get it," Kumara states. He and GM's Jeff Tew included factors such as machine utilization and the time taken to create specific car configurations.
"We made the OTD system Web-based so that many people at GM could access it. Each decision maker needs a different type of data," Kumara says. For example, one person might need to know about machine use, another breakdown statistics.
