quality management Run charts and Scatter charts 60 50 40 30 20 10 10am 11am 12pm 1pm 2pm 3pm Run charts tell you about trends in your project by showing you what your data looks like as a line chart. If the line in the chart were the number of defects found in your product through each quality activity, that would tell you that things were getting worse as your project progressed. In a run chart, you are looking for trends in the data over time. Does it seem to be going up or down as the project progresses? Is there a steady climb or a spike when a particular activity occurs? Scatter charts show how two different types of data relate to each other. If you worked with your test team to create a bunch of new tests, you might use a scatter chart to see if the new test cases had any impact on the number of defects you found. The chart here shows that as more test cases pass, fewer defects are found. # of defects found 60 50 40 30 20 10
