The lengths of the bars represent frequency or cost (time or money), and are arranged with longest bars on the left and the shortest to the right.

Create a cumulative count of all errors and graph it as a new line. Pareto chart (also referred Pareto diagram) is a problem solving tool which is based on the assumption that a majority of problems is caused by a handful of root causes. A Pareto chart is a histogram or bar chart combined with a line graph that groups the frequency or cost of different problems to show their relative significance. You may find in your root cause analysis that multiple errors add up to 80% of problems. You’ll need to change the cumulative data to a line and plot it on the secondary y-axis so that it shows the correct proportion of errors. In essence, the problem-solver estimates the benefit delivered by each action, then selects a number of the most effective actions that deliver a total benefit reasonably close to … It’s important to note that not all problems are equally important to solve. RCFA Training covers the methodology to perform Root Cause Failure Analysis, Failure Modes and Effects Analysis (FMEA), ARCA (Apollo Root Cause Analysis™), and other hot topics currently in maintenance engineering. If the line can’t move because the area ahead of it isn’t moving, record an occurrence in the blocked line category.
