Engineering Change Order
Engineering Change Orders (ECO) are used for changes in components, assemblies, or documents such as processes and work instructions. They may also be used for changes in specifications.
ECOs are also called an Engineering Change Note or Engineering Change Notice (ECN) or just engineering change (EC).
In a typical system development cycle, the specification or the implementation is likely to change during engineering development or during integration of the system elements. These last-minute design changes are commonly referred to as engineering change orders (ECOs) and affect the functionality of a design after it has been wholly or partially completed. ECOs can compensate for design errors found during debug or changes that are made to the design specification to compensate for design problems in other areas of the system design.

Famous quotes containing the words engineering, change and/or order:
“Mining today is an affair of mathematics, of finance, of the latest in engineering skill. Cautious men behind polished desks in San Francisco figure out in advance the amount of metal to a cubic yard, the number of yards washed a day, the cost of each operation. They have no need of grubstakes.”
—Merle Colby, U.S. public relief program (1935-1943)
“Like dreaming, reading performs the prodigious task of carrying us off to other worlds. But reading is not dreaming because books, unlike dreams, are subject to our will: they envelop us in alternative realities only because we give them explicit permission to do so. Books are the dreams we would most like to have, and, like dreams, they have the power to change consciousness, turning sadness to laughter and anxious introspection to the relaxed contemplation of some other time and place.”
—Victor Null, South African educator, psychologist. Lost in a Book: The Psychology of Reading for Pleasure, introduction, Yale University Press (1988)
“The principles of the good society call for a concern with an order of being—which cannot be proved existentially to the sense organs—where it matters supremely that the human person is inviolable, that reason shall regulate the will, that truth shall prevail over error.”
—Walter Lippmann (1889–1974)
