A3 problem solving method
People are the first asset of a company.
Economy during the last 50 years gradually came from the era where cost of products - at the time rare (6 months of waiting for a car,…)- was relatively more important than human cost, to an era where human cost is dominating compared to cost of materials and components. The
development of people competence at all levels is a major factor of good health for companies.

 A3 is the paper sheet format (approx 11"x17") on which the synthesis of the problem solving path is written and told as a story to people taking part in this resolution. A3 = 420mm X 297mm sheet of paper. Toyota adopted this format because it is a wasting to present a work in more than one page.
 Jidoka, sometimes translated Autonomation, or automation with human judgement, is a whole set of techniques. Jidoka is firstly the will to use only one operator to control several machines. Secondly production of a defect or the possibility of producing a defect is immediately announced by the automatic machine which stops instantaneously. Thirdly in manual operations, operators who encounter a “problem” (defect, variation, impossibility of following “standard” of work) must immediately warn their team leader by drawing on a cord. Line is stoped at the end of the operating cycle.
