Add new state option for task in TFS 2012

Question

How can I add new state value for task item in web TFS 2012. I use agile template.

Answer 1

Yes, you can't for the TFS Service but in general for how to do that, you can use GUI by installing Team Foundation Power Tool and start using Process Customization Tool, you will open the Work Item that you want to customize and drag and drop new state, see the following image:

For more information you can see detailed video on how to do that here: http://mohamedradwan.wordpress.com/2011/10/06/customize-tfs-process-2010-video/

Answer 2

Sorry, you cannot modify the process templates on Team Foundation Service at the moment.

There's quite a few restrictions that you can compare here.
