• Small enterprises do not use SCM systems
– Affect more powerful organization to which small
enterprise is linked
• Inventory turns: the number of times the
business sells its inventory per year
• When SCMs of companies are not linked,
demand requirements are unknown, so supply
companies must overstock inventory
• One company “sits” with lean inventory while
other stands with “overstock,” hence musical
chairs

1990s failed, ERP systems helped realize many
of those ideas
– ERP systems forced changes in processes

managing of processes at the organizational
level instead of at the organizational unit level
