Toyota employs the A3 thinking process format in their Toyota lean manufacturing process in three areas: proposals, status and problem-solving.

  • Solutions: Decide the countermeasures necessary to correct the situation. Short-term solutions might be necessary.
  • Plan: Have a plan to implement the countermeasures. The plan should identify roles and a timeframe.
