Global Eight Disciplines (usually abbreviated as G8D, 8D or 8D report) is an analytical technique for solving an unexpected problem. It is a method that is used after the problem occurs, i.e. it is not a preventive method. G8D comes from the USA, where it was developed by Ford. Its roots are therefore in the automotive industry.
