Ishikawa chart

a chart that breaks down the PRODUCTION of a product into its constituent operations as a means of identifying the source of a product defect. Fig. 41 shows a simplified fishbone chart for draught beer. Should a poor QUALITY batch of beer be produced this could be due to a malfunction in any one or more of the operations listed, including faulty or unclean equipment (mash mixers and filters, fermentation vessels), incorrect material mixes or poor strains of malt, hop or yeast, or incorrect boiling and cooling temperatures and periods. Fishbone charts can also be used more proactively to detect and prevent quality problems on a continuous basis as part of a commitment to TOTAL QUALITY MANAGEMENT. See QUALITY CONTROL, FIVE M.
