Is it possible to automate t shirt sizing?

[Erica Hughes]

I have been asked by my PO's if it is possible to automate t shirt sizing by using the start and end date?

[Nic Brough -Adaptavist-]

Welcome to the Atlassian Community!

Yes, it is possible, and with many different tools.  Without reaching for any add-on apps, you could create an Automation that, when an issue is updated, reads the two dates, works out how many minutes/hours/days there are between them and then sets your t-shirt size accordingly.

Hi Nic,

Thanks for your response, this would work to add the sizing after the feature is closed but is there a way for the size estimate to be taken from the expected start/end dates?

Hi @Erica Hughes -- Welcome to the Atlassian Community!

Yes, and...to Nic's answer: please see the diff() function to calculate the difference between the dates.  And then you could use either if/else conditions or a lookup table to select your t-shirt sizing.

To get you started on creating your rule, please refer to these documentation and example sources:

Kind regards,

Thanks Bill, i will take a look.

I have a feeling this is not going to make the process any shorter which is what my PO's are hoping for :-)

Agreed...perhaps consider teaching your product owner an idea from Mike Cohn: "estimate size; derive duration".

That is, the team forecasts effort (as needed) and scheduling is a separate activity (as needed).
