FS1180-1 VARIABLES CONTROL CHART is one type of control chart suitable for recording and charting process performance data. Other types of charts may be used, as appropriate. The FSMS Variables Control Chart Template covers averages, ranges, date/time, readings, and more. The Food Safety Team Leader should analyze the data using appropriate statistical techniques.
To perform adequate and informative analyses, the Food Safety Team Leader should be adequately trained in the use of statistical analysis tools and techniques. Ongoing problems identified with statistical tools, such as the FSMS Variables Control Chart Template, should be subject to analysis, to discover root causes of the problems. Identifying and correcting root causes are central activities in continual improvement. Managers should review data analyses from the Food Safety Team Leader during management review meetings.
The purpose of this phase of the management review process is to analyze the variability of the process and product, using statistical indicators to identify opportunities to reduce or eliminate food safety hazards. After implementation and the collection of statistically significant data, an analysis of the data using techniques such as ANOVA (Analysis of Variance) will be conducted. This analysis will establish the magnitude and direction of the system response to the change.
