Release Defect Trend

The Release Defect Trend app allows you to view cumulative defects opened versus closed over the course of a release, showing whether the trend is increasing or decreasing. The chart visually shows the rate at which defects are being activated (red line), the rate at which defects are being terminated (green line) and the trend for the total number of active defects (black line).

Release Defect Trend

Data displayed in the app is in the same format as the Release Defect Trend chart. Select the chart to go to the Reports tab , where you may view additional information including a key and summary metrics. You may also print, email, and export the chart from the Reports tab.

How the Data Is Calculated

The data for the chart is collected at midnight (in the workspace timezone).

The chart looks at defects in project scope during the time frame of the release. For "today" it looks for defects created today, defects closed today to get today's values for opened and closed, and all defects in project scope not in a "Closed" state for the total active count. Basically, the release's purpose is to provide the time frame.

The chart does not look at the revision history. In the future, you can run analytics based on the revision history. See our Lookback API documentation for more information.

The report and all subsequent data being displayed obeys project scoping.

Data in the chart includes:

  • Cumulative Activated: Defect field OpenedDate for the selected Release.
  • Cumulative Terminated: Defect field ClosedDate for the selected Release.
  • Total Active: Count of all defects where State < "Closed".
    • The Total Active value counts non-closed defects based on the chart's project scoping activity during the release's timebox . This means the count is not limited to defects scheduled during the particular release.
    • Also, multiple actions are being counted against a single defect. This then causes the cumulative defect count to be higher than what you have scheduled into the filtered release.

What About...

Q: So what happens if a defect was created (outside of the release), closed, then assigned to a release, re-opened, and then re-closed, would it appear on this chart?

A: When those things happened comes into play, but if it was closed today, it should show up in the Cumulative Terminated count for today. Timezones could also come into play here, too. Did the defect in question ever belong to a project that isn't in scope? The historical data is pulled from metrics collection run at midnight of the workspace timezone based on projects in scope so if it wasn't in scope when that processing was done, there would not be an entry for it there. In that case, the "today's" value is calculated separately.
