ABSTRACT
If some evil genius were given the job of creating an activity guaranteed to produce an abundance of errors, he or she would probably come up with something that involved the frequent removal and replacement of large numbers of varied components, often carried out in cramped and poorly lit spaces … and usually under severe time pressure. …those who started a job need not necessarily be the ones required to finish it … a number of different groups work on the same item of equipment (Reason and Hobbs, 2003: 1).
