Thun Implements Sigma in Process Optimisation

The American Sigma method of statistical standard deviation is used to evaluate process quality. Optimum processes are designated as 6 Sigma, whilst a totally unregulated process is 1 Sigma.

The better the process quality, the higher the Sigma rating and the lower the associated quality costs. Investigations have shown that the non-conformity costs for a 3 Sigma production process (66,807 defects per million opportunities) amount to approximately 20 to 30 % of turnover. 3 Sigma processes are the standard in German industry, which means that a company with a turnover of ten million euros will waste over € 2 million on ‘defective’ production costs.

These figures enable us to easily work out the potential savings of a 5 Sigma or, even more so, of a 6 Sigma process: instead of the 66,807 defects that occur with a 3 Sigma process, a 6 Sigma process gives just 3.5 defects.

Thun GmbH & Co. KG manufactures its products according to the 5 Sigma processes. Their quality goal for 2009/2010 is the reach the 6 Sigma.

Identification and Traceability

Appropriate tools such as barcodes or RFID are used to identify products throughout the manufacturing process. If traceability is a specific customer requirement, these documents are recorded and retained by the relevant staff involved in the process.
