Use/Calculate PERT in JIRA?

Ti Nguyen

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?
