Calculation of Percentage in Jira Structure

Tristen John Bagain

Hi,

I need to understand the math behind the calculation in Jira Structure at parent level.

On the sample below I need to know formula used to determine 66% at parent ticket level. I included screenshots on how the Progress by Percentage was configured.

Hope to hear from your team soon!

The percentage with purple icon is the parent ticket

The percentage with the green icon are the child tickets

Hello @Tristen John Bagain ,

I see from your screenshots that your progress is weighted by story points. In this case, the total progress is going to be the sum of individual issue Progress (P) multiplied by individual issue Story Points (SP) and then divided by the sum of the story points.

∑(SP*P)/∑SP

Please let me know if this helps!

Thanks, David for the feedback. Can you share how it is computed manually? I tried the formula you gave but I can't get the 66% completion progress on the original screenshot I shared

Hello @Tristen John Bagain ,

You are very welcome! I see two things that are happening here.

The first is the 20% should be 30%, making the SUM of your Progress 950%.

The second is how undefined values are handled. If an issue has an undefined value (blank) in the field you are considering for weight, the progress calculation will assume a value for it.

The assumed value is the average of the values from the issues that do have one defined. In this case the average is 4.69. If you want the weight of the issue to be 0, you will need to enter 0.

Thanks, David. Is the above algorithm true for all other fields that will used for "Weight" (other than "All Sub-Issues are Equal")?

I am trying to understand using this question what is happening on my Structure.

It looks as the picture below, where the right column is the Progress (Rendimiento) based on Status with Weight based on Story Points (the SP are shown on the left column, 3 for the first child issue and 1 for the second).

However for the Parent issue the progress show 88% (average of 76% and 100%) while it should be 82% (76%*3=228 ; 100%*1 = 100%; 228+100 =328: 328/4 = 82%) if the first one is weighted 3 and the second one is weighted 1.

Any idea for the reason to do the average even if the SP are defined for the 2 issues (and the flag "Ignore Parent Issue Progress" is on)

Thanks in advance

Hello @Javier Tejero

The DIFI Epic is also a parent, and its progress comes from the progress of its sub-issues. When it comes to calculating the progress of Ejecutamos issue, the progress and Story Points of sub-issues is being considered, i.e. the values of SOLUCI... issue and the values of sub-issues of DIFI.

I hope this helps. If you have more questions, please reach out to us directly at our support portal.
