“Internal loses” are loses resulting from insufficient quality before dispatch. They are caused by reduced labour efficiency due to additional work, incorrect ergonomics, etc. The term also covers costs related to nonconformities resulting from failure to meet product quality requirements before dispatch (e.g. repeated service provision, repeated production, rework, repeated tests, rejects, etc.). “External loses” are both tangible and intangible loses after dispatch caused by insufficient quality.
