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.
What is G8D used for?
G8D method is suitable for situations where the problem needs to be resolved as quickly and efficiently as possible while protecting customers from unwanted consequences. The method consists of completing the questionnaire, called 8D report (8 Discipline Report) - hence its name. The questionnaire consists of eight parts, disciplines as follows:
