When analyzing a set of data, it can be useful to know if it fits a certain probably distribution, such as the normal distribution. One way to make this determination is by using the Anderson-Darling statistic. In our SPC Knowledge Base article, we look at how the Anderson-Darling statistic is calculated and how it is used to compare how well a data set fits different distributions. https://www.spcforexcel.com/knowledge/basic-statistics/anderson-darling-test-for-normality

Scatter diagrams examine the relationship between two variables and charts the corresponding data for further analysis. Scatter diagrams are one of many important process improvement tools found in SPC for Excel. Learn more about Scatter Diagrams in our instructional video. https://youtu.be/tKrpxfrcoAk

Control charts aren’t just useful for commercial purposes such as manufacturing, customer service, or sales. They can be extremely useful and insightful for personal use, particularly at the start of a new year when you want to track data over time. Today’s SPC Knowledge Base article applies the power of control charts to the sport of baseball. https://www.spcforexcel.com/knowledge/control-chart-examples/control-charts-and-americas-favorite-pastime-baseball

If you were able to produce a product to specification but with a lot of waste and delays, would this be considered efficient? Probably not. Similarly, if you are just able to meet production goals but with machinery and equipment running at only half of their capacity, this would not be considered efficient either. Our SPC Knowledge Base article examines production downtime, uptime, and Overall Equipment Effectiveness. https://www.spcforexcel.com/knowledge/control-chart-examples/spc-downtime-and-overall-equipment-effectiveness
Describes how to apply SPC to monitor downtime and overall equipment effectiveness.

Process capability measures how well your process meets the specifications required by the customer. This measurement is crucial to manufacturers so they know if they are meeting production goals, and what types of improvements may be needed if goals and specifications are not being met. In today’s SPC Knowledge Base article, we introduce a 15-step methodology for improving process capability by examining the accuracy and precision of test methods, reviewing sampling methods, and applying experimental design techniques. https://www.spcforexcel.com/knowledge/process-capability/cpk-improvement-methodology

Many companies rely on Key Process Indicators (KPIs) to gauge how an organization is performing based on specific metrics. Although KPIs can be invaluable to achieving goals and process improvement, some companies make the mistake of choosing the wrong KPIs to track, which can delay or completely derail process improvement measures. Today’s SPC Knowledge Base article looks at how to monitor KPIs over time and create performance measures that link to these KPIs. https://www.spcforexcel.com/knowledge/control-chart-examples/kpis-control-charts-and-linking-measurements
Describes what KPIs are, how to link them throughout the organization and how to use control charts to display them.

Part of creating a control chart is also setting control limits for your data points. However, these control limits may need to be adjusted as you gather more data points to analyze. Our SPC Knowledge Base article examines how to set control limits, when they should be recalculated, and when they should be locked in. https://www.spcforexcel.com/knowledge/control-chart-basics/when-calculate-lock-and-recalculate-control-limits

Process improvement isn’t truly effective if the focus is solely on the process and not on the people who perform or manage the process. For a process to truly be improved, it takes improved people skills and training in order to minimize variation and its causes. In our SPC Knowledge Base article for today, we examine the balance that must occur between improving process skills and people skills to achieve improvement. https://www.spcforexcel.com/knowledge/process-improvement/balancing-people-and-process

We often take samples to find something out about a process. But how many samples do we need? It depends on a number of items. What difference do you want to be able to detect? What is the variation in the process? And what power do you want? In SPC for Excel, we offer Power and Sample Size Analysis in our software for this very purpose. Learn more in our SPC Informational video. https://youtu.be/UG44F_-NMaE

Too often, companies can become overly focused on achieving goals without realizing there are slowdowns, inefficiencies, wastefulness, and repetitive issues that impact overall productivity. What if it was possible to achieve goals and meet customer specifications while also reducing waste and improving efficiency? Today’s SPC Knowledge Base article focuses on variation and how it can impact our process improvements and daily operations. https://www.spcforexcel.com/knowledge/variation/returning-basics-variation
January 2012. Our first newsletter of the year goes back to the beginning - variation - just where you should begin with statistical process control - ensuring that everyone understands the concept of variation. The control chart approach to quality (with common and special causes) is totally different from ...

Companies will often use pay for performance incentives to help motivate workers and teams to achieve specific production goals. However, this strategy can often be ineffective because it assumes that workers can control the system, and that money is an effective motivator for employees and teams. In today’s SPC Knowledge Base article, we study pay for performance incentives, and how variation is often overlooked. https://www.spcforexcel.com/knowledge/variation/variation-people-and-pay-for-performance
When we talk about statistical process control (SPC), we usually do so in terms of manufacturing of products. Of course, some of you have taken SPC to the service industries as well. But even then, it is usually in the context of how to apply control charts in the environment. Sometimes we forget that SPC ...
