We are using Trello for project management of a dev project. Here is how we are working currently:
Developer takes a card assigned to them from the Todo pile and moves it to Doing then the Developer works on card and moves it to Done.
Then the task / module / card has to be tested for functionality / bugs etc so what often happens is that the cards get moved back to Doing as more info is added into the comments section of the card about something not working / looking right.
Is this the best way to iterate / give feedback on cards? Or is there a better / more accepted or standardized workflow? Would you have a staged or for testing column in between Doing and Done?
