Reminder--What the LEM Is
Insight Tool
− a framework for organizing lean principles, practices &
supporting examples
− value stream focus on customer; product creation,
fabrication & assembly; supply chain; people &
organizations; policy & environment; information systems
!
Electronic Library
− originally for LAI research mapped to LEM
