Sequence break
In mechanical engineering , a sequence break in parallel running sequences refers to the shifting of the process of at least one of the sequences (e.g. by leaving out an element of this sequence). At least two sequences are necessary for this.
example
During vehicle assembly, the engine is built into the engine compartment. The normal consequence without a sequence break could be that a 1.9 TDI is installed in a vehicle intended for this purpose, followed by a GTI engine in the corresponding next vehicle.
If a sequence break occurs, the 1.9 TDI engine could inadvertently be positioned in the GTI vehicle.
