Yokoten is a Japanese term that can be roughly translated as "across everywhere." In a Lean company it is used to mean "best practice sharing".  This is an essential tool for implementation of the Lean principle of Standardized Work.   This is sometime called 'The One Best Way' to do an activity or task,  and it should be recognised and then Yokoten used to make sure that this 'One Best Way' is followed by all workers across the organization.
