Kaizen, lean production, and agile principles were brought to widespread attention in the 1980s and 1990s as approaches to operational efficiency and effectiveness.

The document asks for an assessment of the ongoing relevance of kaizen, lean thinking, and agility in today's business operations and supply networks based on post-2000 literature.
