long-term impacts

The Toyota way or Entropy? What did we find when we went back 8-9 years after improving management in Indian factories?

David McKenzie's picture

Between 2008 and 2010, we hired a multinational consulting firm to implement an intensive management intervention in Indian textile weaving plants. Both treatment and control firms received a one-month diagnostic, and then treatment firms received four months of intervention. We found (ungated) that poorly managed firms could have their management substantially improved, and that this improvement resulted in a reduction in quality defects, less excess inventory, and an improvement in productivity.

Should we expect this improvement in management to last? One view is the “Toyota way”, with systems put in place for measuring and monitoring operations and quality launch a continuous cycle of improvement. But an alternative is that of entropy, or a gradual decline back into disorder – one estimate by a prominent consulting firm is that two-thirds of transformation initiatives ultimately fail. In a new working paper, Nick Bloom, Aprajit Mahajan, John Roberts and I examine what happened to the firms in our Indian management experiment over the longer-term.
