Thank you Meenakshi for the excellent talk , there is a push to use framework that supports executable specs like cucumber , speckflow , Fitnesse etc where a BA , PO etc also can get involve in defining the requirements.
In Postman I prefer to use data driven testing and uses csv to drive my entire automation , but it would be great to have some central portal like the collection runner where BAs can define the buissness cases , eg like in Fitnesse table ;

Another thing all the people I interact with and myself voice for is to have something like htmlextra report in collection runner. There should be a way of downloading the run result has html report from the collection runner
