PBC Analyzer Preview
A Sneak Peek of My New Educational Tool for Creating and Learning About Process Behaviour Charts
THE AIM for this short post is to share a brief demo of a new tool I’ve been working on to for creating, experimenting with, and learning about PBCs while you use it. It’s called PBC Analyzer, and in the video above you can see how to:
Create a standard Process Behaviour Chart with highlighted Rule 1 and Rule 2 signals;
How to change the Baseline Period for calculating the process limits
How to add visual markers to aid in slicing the data
How to analyze a subset of the data by skipping and trimming rows
How to add/remove elements from the chart using the chart’s controls
How to plot a distribution chart of the results
How to export an analysis back to Excel with all required calculations done for you
My aim for the tool was to make analyzing data in a PBC quick and easy while teaching something about how they work for the bargain, particularly the relationship between the data points used for the baseline period and the calculation of the upper and lower process limits which affect the sensitivity of the chart for showing signals. Other options, like highlighting the sigma unit bands (not shown in the video) will also show how the process limits work to progressively filter out “noise” so only signals will show above or below the limits.
My hope is that by getting you involved in creating charts from real data straightaway, your desire to learn more about how they work and what they are and are not used for, and how to build them yourself is increased.
When Will It Be Generally Released?
As a thank-you to my paid-tier supporters, I’ve released the tool for their review and feedback first and plan to make it generally available in about a week, as I did with the Red Bead Experiment Simulator.
As a reminder, this is a step along the way to building a more interactive web-based application to enable even more advanced analyses with features to allow for recalculating limits at specific points to “shift” them and follow the variation as it moves through different periods.
