Control chart example ppt

A key SPC tool is the control chart, which is the focus of this presentation. Combines Example: Control chart of appointment access satisfaction. Johns Hopkins 

Client Retention Solution Ppt PowerPoint Presentation File Example File control chart, pareto analysis, scatter diagram, process flow chart, histogram. The chart is out of control if one or a combination of the following four examples occur: Process out of Control 1. If one point falls outside of the 3 sigma control limits (beyond zone A) Process out of Control If two out of any three successive points fall in zone A of the same side Process out of Control 3. Interpret control chart results • Range chart first to ensure stability of KPI metric process: because no ranges are outside the RLCL or RUCL, the wait time process is in control 21. Interpret control chart results • Rule violation 1 - four consecutive data points in a row trending up or down merits a caution. C CHART The procedures for c chart are the same as those for the p chart. If count of nonconformities, is unknown, it must be found by collecting data, calculating UCL & LCL. = average count of nonconformities ccUCL 3 ccLCL 3 g c c 13. Charts convey information through the aid of graphic symbols, images, and diagrams. There are several types of charts that we’re almost too familiar of, like flowcharts, pie charts, bar charts, etc., since we have been learning from them for quite a long time.One of such charts is a control chart, which we will be discussing in this post. Examples of Control Charts. The most typical examples of a control charts include the following; click on the links to download samples. U Charts – These variable types of control charts utilize an upper and lower range. Elements falling in the upper range need attention and analysis in order for the problem to be corrected.

10 Control Charts. Example 13.2.1 Telstar Appliance Company uses a process to paint refrig- erators with a coat of enamel. During each shift, a sample of 5 

In the example below, a bottle company fills their bottles to 16 oz. (mean); they are evaluating if their process is “in-control”. The amount in ounces over 16 oz. is normally distributed around the mean. Measurements need to be independent of one another. In the example, the measurements are in subgroups. Control Charts originally developed by Walter A. Shewhart Control Charts The control chart is a statistical quality control tool used in the monitoring variation in the characteristics of a product or service Control Charts The control chart focuses on the time dimension and the nature of the variability in the system. 13.1 Introduction 1 CHAPTER 13 of Chance Encounters by C.J.Wild and G.A.F.

Mean Value Control Charts Types • Laboratory Control Sample (QC samples) – Charting the results over time of the same sample • Matrix Spike Control Samples – With each batch (however defined) of samples a blank matrix sample is spiked with desired analyte.

The PowerPoint chart templates example cover a broad range and would include anything from pie charts, column charts, surface charts, stock charts or doughnut charts. If you are looking to stand out with your PPT, you must make sure to include the Chart Templates in your presentation. Why is the PowerPoint Chart Template Needed?

An example of a common quality characteristic classification would be designating units as "conforming units" or "nonconforming units". Another quality   quality control sample. • By plotting this information on a chart, a graph is produced in which the natural fluctuations of the measured value can readily
