The Blocking Analysis view helps you to analyze the most common reasons for blocking the cards by teams. You can do a Pareto analysis by looking at causes of bottlenecks because it helps stimulate thinking, organize thoughts, and continuous improvement. You can take corrective measures to address these reasons based on priority in the retrospectives.
To do a Blocking Analysis, ensure that the policy 'Attach reason code while Card Blocking' is set for your board.
On selecting the required filter
options, the chart shows total Blocked Time of cards that were blocked/unblocked in any columns within the Start and End column. It includes cards that have been blocked/unblocked within the Filter date range and includes cards blocked before the Start date or remain blocked until the End Date.
The Blocking Analysis view shows two charts:
- The Time Lost to Blocking histogram on the left side, which enables a Pareto Analysis of Blocking Reasons and the time loss each Root Cause is contributing to. It plots the total Blocked Time of cards on the X-axis for a particular blocking reason. Hover on the bar to view the blocking reason and card count.
- The # of Cards Blocked chart, which gives you a visual on the relative distribution of cards across different Blocking reasons. Hover over a pie to view the blocking reason and the card count.
Click on the bar/pie to drill down to view the card-level details.
In short, you can analyze what was the loss of productivity/time/value because a card was blocked during that time for any period of time.
