Integrating Lean and Agile Thinking: Concepts in Support of PracticeThe emergence of Just-in-Time (JIT) manufacturing in the 1980s signified a turning point in logistics management and the development of what is now called lean supply.
A paradigm shift in thinking occurred and the role of inventory was reversed: the emphasis changing from holding inventory to cover the disruption caused by system fluctuations, to removing inventory to expose the fluctuations. A systems approach to managing the supply chain emerged, which centred on the incremental reduction of wasteful internal variation supported by stable production schedules. This strategic approach, which is naturally suited to large and stable volumes, challenged established management theory and long established trade-off models.
