Course details


In order to address long-standing problems in a process and to ensure solutions are of value, we need to identify the root causes driving process problems. We need to analyze the impact of each potential input (X) on the output (Y), both graphically and statistically. If we can’t create a graph to show the impact, or non-impact, it will be very difficult to convince the stakeholders to take action or discard the myths. Statistical analysis then validates the graphical analysis.

In this 90-minute online session, we will introduce you to a fundamental concept of process data analysis and a structured approach. This will enable you to identify and qualify the impact of your inputs on your process output.

Agenda topics:

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 purposeful 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 graphical techniques to visually assess an input’s effect on the response, and communicate these preliminary results with others. We will introduce the following to begin this journey:

  • How to select the appropriate chart for your inputs.
  • How to use control charts.
  • Other charts useful for analyzing variable output.

Applying statistical techniques. A fundamental piece of analysis is to discern your data from a desired target. The tests we introduce will provide backup to the indications that we obtained from our graphical analysis. We will use:

  • Hypothesis tests to determine significance for means and variance.
  • Regression analysis to explore relationships between X and Y variables.
  • ANOVA to distinguish sources of variation and how they can affect your primary metric.
