Dead on arrival

Dead on arrival or DOA is a notation that a patient was brought to a hospital and immediately pronounced dead by a physician. The term arises because first responders such as emergency medical technicians (a.k.a. paramedics or ambulance drivers) do not have the authority to pronounce a patient dead (in the U.S. at least), and they are obliged, in the absence of a do not resuscitate order, to attempt resuscitation if there is any possibility of life and to continue resuscitation until the patient has been examined by a physician, which usually occurs only after the patient has been brought to a hospital.
Colloquially, anything which is received in a non-operational (broken) state can be called DOA or dead on arrival. If a new product, such as a computer, arrives "DOA" then it is likely that the recipient will call the supplier to get a Return Merchandise Authorization (RMA), a transaction that acknowledges that (apparently defective) goods will be returned to the supplier for refund, replacement or credit. Sometimes it is difficult to actually detect a defective or DOA product. With computers, for instance, it might require a boot image to be installed and run through a test suite to detect any failed parts.
When, as with computers, product complexity is high and diagnostics are involvee, the medical metaphor is perhaps appropriate, as complex diagnostics might be required to determine if the product "is really dead".nl:DOA Template:Med-stub
