Supply Chain Fundamental Rethinking

Continuing with the thoughts of Lean in 21st century I think, one major dramatic change vis-a-vis 20th century when Lean was introduced, is the element of "Information Systems". Lean was developed in a period of time when information integration was a major challenge. Hence many instances of Lean will find traces of efforts being put to facilitate information integration. e.g. Kanban system. Another supplementary issue is information distortion. This makes the entire organization be sub-optimal. Many information systems developed in Lean have roots of trying to over this issue. e.g. Moving from Push to Pull systems. While enterprises develop & deploy Lean in 21st century, Information distortion may still exist, courtesy various organizational practices & metrics. A culture of rewarding "Heroes" also creates the need to use information bias in ones favour. But that doesn't take away the reality that adopting technology solutions along-side the l

Taking it forward from the previous post ( http://blog.think-spark.com/2017/04/lean-people-element-in-21st-century.html ) the second most important need for Lean is "Demand".  Going by the philosophy in its true sense it states that Demand variability should be low & the  variety to be handled should not be very high. Both these have real life sense in the mid 70's & both were valid. (this also coincides with the time when the philosophy received a wide recognition around the world). The rapid change in the business environment over the past three decades has ensured that the rate of change & the variables impacting the change both have upward trajectory. A mid size organization today handles a few thousand SKU's. Applying any of the Lean principles or its techniques either on the Shop floor or in the Supply Chain under estimates the core element of Lean i.e. the ability to handle variety & variations. Most of the Supply Chains have evolved o
