Problem

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

Solution

This recipe assumes that you already have a project and a workflow associated with it in your Jira installation. If not, go to the Jira documentation to find out how to do this.

Add a SIL post function

Create a draft workflow.
Go to the Create transition.
On the Post Functions tab, select the Add checkbox.
Select (k) SIL Post-function and click Add.

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

Write the code

After you’ve added the post function, 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 functions.

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.

It is recommended that you move the SIL™ post functions after all other post functions. To do this, click Move Down until the SIL™ post functions reach the bottom of the post functions list.

Test the code

Publish your draft workflow to activate it.

To test the post function, 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);
}
