Organizational Process Recommendation - Essay Example The control chart is basically a graph which is used to study the changes in processes over a particular period of time. The chart has a central line for the average, an n upper line which represents the upper control limit and a lower line which represents the lower control limits. The lines are determined using historical data. The comparisons of the current data to the above lines, a conclusion can be drawn about whether the variation in the process is consistent (implies process in control) or unpredictable (implies process out of control which are affected by special causes of variation). A control chart is based upon the statistical feature of normal distribution. The considerations of probability form the basis of the control limits. These basically depict whether the system in control are supported or not. The control charts can also be used to warn about the potential system problems. These charts also reveal the need for corrective action. Control charts are always prepared in real time. The procedure involves choosing an appropriate control chart for a particular data set, this is followed by determining the appropriate time period for plotting and collecting the data. The next step involves collecting the data, constructing the chart and analysing the data. Further the out of control signals on the control charts are determined and suitable steps to correct them are undertaken. The values that are obtained for repetitive measurements processes are plotted sequentially for evaluating the stability of the measurement process. These should be very similar to the test samples of interest. The absolute differences (R) of the duplicate measurements are sequentially plotted for evaluating the precision of management process. The average range which is related to the short term standard deviation. A t test is undertaken to assess whether the mean of the second set of data is has significant differences from the first set of
