1/3 of a user story is devoted to the persona - but how teams usually spend far less than that on designing and understanding the persona we are creating work for!
Personified helps by bringing the persona to the forefront of every user story and with the ability to link to more details if required.
Best yet, you control where and how the persona is shown. On installation, a new custom field is created which can be shown on any issue type.
Once a persona is selected within an issue the persona image is updated and the summary details are shown.
