A better collection of data at the shop floor level, serious analysis

and to turn its attention to a more difficult one, the loss of confidence
that had resulted in greatly reduced orders. The supplier analysis
of the biggest customer showed clearly though that things were improving
very quickly and greatly. This helped not only with this customer.
The percentages in the above graph are production hours out of total hours
available. The unproductive hours therefore include such necessary
times as re-tooling and maintenance which can only be done during production
hours in a plant that runs 24 hours a day.
