Details

1. What does the expression do?

This expression counts how many times the assignee of a work item has been changed or cleared. In other words, it tells you the total number of times the "Assignee" field was updated in the work item's history.

2. Step-by-step breakdown

Let’s break it down:

• issue.changelogs: This refers to the complete change history (changelogs) of the current work item. Each changelog entry represents a set of changes made at a specific time.

• .filter(changelog => ...): This filters the changelog entries, keeping only those where the assignee field was changed.

• changelog.items: Each changelog entry contains a list of items, where each item represents a single field that was changed in that update.

• .some(item => item.fieldId == 'assignee'): This checks if any of the changed fields in that changelog entry is the "assignee" field.

• The filter keeps only those changelog entries where the assignee was changed.

• .length: This counts the number of changelog entries that passed the filter, i.e., the number of times the assignee was changed.

3. Examples

• If a work item was assigned to Alice, then to Bob, then cleared (set to no one), and finally assigned to Carol, the expression would count 3 changes (Alice → Bob, Bob → none, none → Carol).

• If the assignee was never changed, the result would be 0.

4. Real-life use cases

• Audit and reporting: Track how often work items are reassigned, which can help identify bottlenecks or frequent handovers.

• Team workload analysis: See if certain work items are being passed around too much, indicating unclear ownership.

• Process improvement: Monitor if work items are often unassigned, which might signal process gaps or delays.
