Aims to eliminate:
1) Over production- producing more than needed- stop flows of matieral
2) Waiting Time- Waiting for next step or not enough inputs to comintue process
3) Transportation time- Wastes energy, resources and fuel. Significant costs spent moving stock
4) Excess processing- extra processes taking original raw matierals furthur from natural state
5) Excess stock- Over produced, stored untill needed. Warehousing, tracking and monitoring, risk of products becoming absolute
6) Excess motion- Unnecersarry activites within the workspace. Bending, motion, lifting, stretching
7) Product Quality- Quality is inferior, cause scrap and rework, costs to manafacutring process and waste
