“SEQUENCE ERROR” (Computer Science) SEQUENCE ERROR is an error that arises when the arrangement of items in a set, does not follow some specified order. “Sequence Error” is inspired by the well known Karl Marx quote, “History repeats itself first as tragedy and than as farce”, and re-uses parts of two famous speeches of the 20th century delivered by Che Guevara (1963) and George Marshal (1947). In a contemporary corporate environment and on the occasion of a sudden system crisis, two leaders of two different groups (workers vs. executives) deliver some parts of the two aforementioned speeches.
