At the BEGINNING Of the project: Yay!! Lets automate and cover all test scenarios!! Lets work towards increasing the test coverage !!
After 1 year: Regression suite is too bulky!! I can't maintain it anymore!! Its too flaky!! 
Does this conversation ring a bell? Well, this is a common scenario in projects. The UI test automation starts as a saftey net and then becomes a trap net!
Heavy Functional tests layer → Long execution time → Low confidence → Problem of Maintainence
This talk will address these problems in an Agile project. Some solutions that worked in our team. How working as a Team would help prevent these problem?
