Use Atlassian's end-to-end design language to create straightforward and beautiful experiences.
It's fair to say that a lot of designers have a dislike (or probably a fear!) of going anywhere near tools like Jira or Confluence - while everyone else in a product team will be using them.
But as an organisation it's clear that Atlassian have recognised this, and are making steps in the right direction to create better designed products. Their software is super complex so it will be a difficult task to simplify and redesign the UI across the board, but when they get there I think they might just earn some credibility with designers along the way.
It's great to see that a company like Atlassian are starting to see the importance of design and making steps in the right direction.
It would have been nice to see more reference to 'jobs to be done' rather than personas, which feel a bit stuffy.
