With 4 years of continuous efforts in bringing Quality Improvement through DOFR the yield of continuous casting plant (Stand Pig Casting Machine) could not be improved beyond 92 to 93% by any of the available improvement theories & techniques like:
- TPM (thru JIPM)
- Theory of Constraints
- TOP (McKinsey model)
- Six Sigma
