Use/Calculate PERT in JIRA?

Hello everybody,

As the title said, I want to use/calculate PERT for all issues, included subtasks

I have created some custom fields:

  • number fields: mintime, maxtime, normaltime, perttime
  • scripted field: pertcalc

here is the inline script for pertcalc:

import com.atlassian.jira.issue.CustomFieldManager;
import com.atlassian.jira.issue.fields.CustomField;
import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.Issue;
import com.atlassian.jira.issue.ModifiedValue;
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder;
import com.atlassian.jira.util.ImportUtils;
import com.atlassian.jira.config.SubTaskManager;
def cfManager = ComponentAccessor.getCustomFieldManager();
def pertsum = 0;
pertsum += calc_pert(issue);
SubTaskManager subTaskManager = ComponentAccessor.getSubTaskManager();
Collection subTasks = issue.getSubTaskObjects();
if (subTaskManager.subTasksEnabled && !subTasks.empty) {
  subTasks.each {
    pertsum += calc_pert(it);
def pert = cfManager.getCustomFieldObjectByName("perttime");
pert.updateValue(null, issue, new ModifiedValue(issue.getCustomFieldValue(pert), pertsum), new DefaultIssueChangeHolder());
   return pertsum.toString();
double calc_pert(Issue issue)
    double p = 0;
	def min=issue.getCustomFieldValue(cfManager.getCustomFieldObjectByName("mintime"));
       def mindouble = (double) min;
	def mayx=issue.getCustomFieldValue(cfManager.getCustomFieldObjectByName("maxtime"));
       def maxdouble = (double) max;	
	def nnormal=issue.getCustomFieldValue(cfManager.getCustomFieldObjectByName("normaltime"));
       def normaldouble = (double) normal;
    p = (mindouble +  maxdouble + 4*normaldouble)/6;
    return p;


The problem is the number field "perttime" does not get any result

so I guess I should have made some mistakes, maybe at those with "getCustomFieldValue" and "getCustomFieldObjectByName"


Hopefully someone may help me solving this

Start with debugging what the fields are returning - your code assumes they are numbers, and that they are all filled in for every issue you are examining - are both of those actually true?

Did you mean that I should try with script console?

if yes, i got the error:

No such property: issue for class: Script71

groovy.lang.MissingPropertyException: No such property: issue for class: Script71 at

If you are going to try this in the script console, then you will need to add code to the top of it to say which issue to work on.

but is it the right syntax to read the value of the custom fields?

for example:

def min=issue.getCustomFieldValue(cfManager.getCustomFieldObjectByName("mintime"));

if i remove those code with getCustomFieldValue, then the number field perttime receive "0" from scripted field "pertcalc"

so I guess everything else works correctly except those with getCustomFieldValue

That looks right to me.
