S+B: How do you find the right approach, the right methodology, to reach excellence in your plants?
LURQUIN: Over the past decades, I have seen methodologies come and go: total quality management, quality circles, outsource everything, lean manufacturing, Six Sigma, and so on. You need to find the methodology that suits your company, its culture, and its level of evolution. It has to be adaptive. Having said that, the foundations of an adaptive culture are a strong vision and, even more important, strong values. There needs to be both trust and transparency among the various actors in the operations. The rest you can then tailor and fix. To me, there is nothing worse in improvement programs than following a mechanistic, Cartesian, one-size-fits-all model.
