What do you like best?
How easy it is to create stories and tasks.
Also documenting Acceptance Criteria and task details such as test processes and results.
The multiple views of stories is great too:
Iteration Status, team status, Team Board, Swim lanes organizing related stories.
We started using colors and swim lanes as soon as they were available. There great.
What do you dislike?
The Swim Lane view of stories does not include the points for each story in the bottom right corner
as is shown for stories in the Iteration Status view.
We would use the Swim Lane view more if the points were shown there too.
Especially in PI planning meetings.
We assign colors to related stories and the swim lane view groups them by color but
then we can't see how big each story is or set the number of points to each story there.
We have to go to the Iteration Status for that, causing lots of flipping back and forth.
All story info should be displayed any where a story shows up.
Recommendations to others considering the product
Better abilities to fully document stories and tasks with large documentation fields such as descriptions, acceptance criteria, test results, notes, etc. that other tools I've used.
Also lots of ways to organize and group stories:
By Release, iteration, expedite, milestone, story type, colors, swim lane priority, etc
We don't always use all of them but the are nice to have if we need them.
What business problems are you solving with the product? What benefits have you realized?
Creating typical agile stories and tasks, documenting Acceptance Criteria.
Also sometimes test processes and results for future reference.
