Online Training: The Story of Your Data -- Session 3: How to Become an Attribute Data Detective

In this 90-minute session we will discuss historical attribute data and, using a case study, we will explore what the data does and does not tell us. We will introduce specific statistical and graphical tools that process improvement practitioners can utilize to provide insights into their baseline process and identify root causes.

Overview

Process exploration and analysis for an attribute output can be tricky. As with all process improvements, we must implement change in a way that is sustainable, and be confident the change was successful. First, we must try to understand how the process currently functions by collecting and visualizing data on the process. Then we need to analyze the impact of each potential X (input) on Y (output). But does all of this work if we are counting things rather than measuring them?

In sessions 1 and 2 of this series, we focused on understanding and analyzing variable data. In this 90-minute session we will discuss historical attribute data and, using a case study, we will explore what the data does and does not tell us. We will introduce specific statistical and graphical tools that process improvement practitioners can utilize to provide insights into their baseline process and identify root causes.

Agenda topics:

This session will cover five key concepts that will enable you to effectively understand your attribute process output data and help you communicate the process performance to your organization:

Where to start with your data. When we get our data, one of the most helpful initial tasks is to determine that it is attribute data and that it is not possible or feasible to obtain process output in variable terms. Also knowing more about the root source of your data and confirming that it is attribute and not variable will help us embark on the correct journey. We will explore count data and how this differs from proportion data, introducing the Binomial and Poisson distributions. We can then produce simple summary tables to give us a sense of our process.

Using graphs to know your process. Graphical analysis is a powerful tool and can be used not only to get insights into your process but also to share these insights with others. Some graphs help us to know our data and others help us to show our data. We will introduce key charts that will help you to learn more about your process output. These are the:

  • Pareto chart
  • Pie chart
  • Bar chart

Assessing your process capability. Ultimately one of the key questions we can ask is whether our processes deliver what our customers desire. Capability analysis takes our data and compares it with our customers’ specifications. Using common probability models we can not only create a snapshot of our performance but also predict our future ability to deliver to the customer specification. We will specifically focus on:

  • How to run a capability analysis for defect data.
  • How to run a capability analysis for defective data.
  • How to get sigma level for attribute data.
  • How to work with summary data.

Y=f(x) is the basis of process knowledge. We may be unhappy with the performance of our process in terms of the output but until we understand the relationship between the inputs and the outputs, we cannot make considered changes to gain improvement. Exploring the relationship between the inputs and outputs is fundamental to our ability to conduct graphical and statistical analysis.

Identifying the “vital few” inputs. In the Analyze phase we begin the process of identifying the vital few inputs from the trivial many. We can use statistical analysis to uncover the main drivers of the process output. We will introduce the following to begin this journey:

  • Stratification of Pareto charts.
  • Chi-Square tests to explore the independence of defect data.
  • Hypothesis tests to determine significance for proportions.
