We present an empirical study of a service system in which the servers have discretion over both selecting which tasks a customer requires and the duration of task completion. Using operational data from a hospital emergency department, we show that when crowded, multiple mechanisms act to retard patient treatment, but care providers adjust their clinical(More)
Successful application of concurrent development processes (concurrent engineering) requires tight coordination. To speed development, tasks often proceed in parallel by relying on preliminary information from other tasks, information that has not yet been finalized. This frequently causes substantial rework using as much as 50% of total engineering(More)

A distinctive feature of this retailer is that it allows consumers to repeatedly submit offers on one and the same product.

Rather than posting a price, the retailer waits for potential buyers to submit offers for a given product and then chooses to either accept or reject them. Consumers whose offers have been rejected can invest in additional haggling effort and(More)
