A control chart (Shewhart chart) provides more information and is more sensitive than a run chart
. In a control chart, control limits and zones are added to the chart and allow the team to predict process behavior and capabilities.
The run chart
in Figure 3 shows the overall process behavior for the AOI over the 7 years (Quarter 1-2006 through Quarter 4-2012).
How can one use the run chart
information for each individual process measure to create a single indexed number to reflect the organization's performance for the so different processes?
As well as averaging in excess of 80 in first-class cricket this summer, he also topped the domestic Twenty20 run chart
The ninth anaesthetist's data was then analysed separately, using a simple run chart

deficiency reports by provider or location.

data must be collected over time in an orderly time sequence (monthly, weekly, quarterly, etc.).
New features include: an overlay run chart
)that compares individual sample observations for a process characteristic; a high/low run chart
that compares extreme spreads in sample data; a capability report that features both box chart and tabular displays when capability indices are applied to the process data; charting on user-defined ranges of data as well as entire sample populations; global reporting across multiple parts or processes on management reports; real-time e-mails for out-of-control conditions; automatic control trend warnings triggered by non-random patterns in the data; and simplified data relinking when file locations change.
Another way to look at process phenomena is with a "run chart
," which plots the value of a particular process variable over numerous shots.
