Since  the  dawn  of  human  existence  evolution  in  all  sectors  of   society  has  occurred  due  to  Economic  factors.   This  has  mainly  happened  due  to  the  fact  that  all  technological  achievements  have  occurred  in  favor  of  money. Specifically  we  can  admit  that  Economy  is  the  main  reason  for  growth  and  development. By  these  means  it  is  in  our  interest  to  establish  strong  economies  either  as  societies (macroeconomics)  or  as  individuals (microeconomics). For  these  reasons  several  techniques  and  methods  have  been  initiated  in  order  help  modern  individuals  to  develop. Such  techniques  are  usually  Accounting  or  Managerial  in  their  nature. However  one  of  the  most  important  technique  is  both  an  Accounting  and  a  Managerial  technique  and  is  called  "The  just  in  time  method". Just  in  time  manufacturing "was  an  inventory  control  approach  that  was  developed  by  Taiichi  Ohno  at  Toyota  Motor  Company  of  Japan. Specifically  it  requires  that  "the  exact  quantity  of  defect-free  raw  materials, parts  and  subassemblies  are  produced  just  in  time  for  the  next  stage  of  the  manufacturing  stage" (Ivancevich-Lorenzi-Skinner, p 427). That  actually  means  an  inventory  is  never  large  and  by  this  way  cost  is  being  reduced  due  to  the  fact  that  there  are  no  losses  of  materials  due  to  bad  demand  or  spoilt. This  method  is  totally  a  demand - driven  process  since  inventory  value  represents  the  exact  value  of  raw  materials, parts  or  subassemblies  that  must  be  spent  to  satisfy  orders  that  have  already  taken  place. By  these  means  the  company  is  never  overstocked  and  that  has  as  an  affect  that  the  company  will  never  have  a  liquidity  problem  since  assets  as  stock  of  goods  are  smaller  and  cash  is  bigger. Another  reason  for  this  to  happen  is ...
