Problem

You want to assign new issues to the user with the least number of tasks to balance the workload across the team.

Solution

Add a SIL

action

1. Create a draft workflow.

2. Go to the Create transition.

3. On the Post Functions tab, select the Add checkbox.

4. Select (k) SIL Post-functionAction and click Add.

For more information on configuring workflows, go to the Atlassian documentation.

Write the code

After you’ve added the post functionaction, the user interface is displayed.

Enter a name for your program. This is used in the name of the file where the program is saved. For more examples, go to our documentation on writing condition validators and post functionsactions.

To assign an issue while also maintaining the user load, enter the following code.

string[] prjMembers = projectMembers(project);
string minUser;
number minIssues = -1;
number issuesNumber = -1;
string query = "project = " + project + " AND status in ('Open', 'In Progress', 'Reopened') AND assignee = ";
string jql;
 
for (string user in prjMembers) {
  jql = query + user;
  issuesNumber = arraySize(selectIssues(jql));
  if ((minIssues == -1) || (issuesNumber < minIssues)) {
    minIssues = issuesNumber;
    minUser = user;
  }
}
 
assignee = minUser;

Click Add.

Test the code

Publish your draft workflow to activate it.

To test the post functionaction, create a new issue. Complete the required fields and click Create. The issue is assigned to the user with the smallest number of tasks.

Example

This is an example of how you can randomly assign an issue to project users.

To assign the issue randomly, enter the following code and make sure to use the random function.

string[] prjMembers = projectMembers(project);
number n = arraySize(prjMembers);
 
if (n > 0) {
 assignee = arrayGetElement(prjMembers, random(n));
} else {
 assignee = projectPM(project);
}
