Our scrum room looked like this:
Despite making my living utilizing tech, it proved difficult to defend the 'old school' post-its and whiteboards. There were a few things that compelled me to keep my distance from Agile tool sets. For those of you that utilize more sophisticated tool chains, good on ya and I'm not implying there is anything wrong with them.
Licensing costs, risk of loss of proprietary information in cloud-based systems, feature sets that I trust we'd never use (e.g. burn-down charts and metrics) and most importantly I personally felt the satisfaction of disclosing your task completion and physically moving a task from 'in progress' to 'complete' with a sense of accomplishment. My resistance was reinforced when participating in sprints led by other scrum masters that used 'MS Excel' (I know, wrong tool) and the tone of the meeting became more a status meeting than a scrum.
I yearned for a scrum room with a wall-sized electronic smart board; electronic equivalent of post-its and baby, Trello is pretty close to what I wanted.
Free to use, flexible, and pretty much what the doctor ordered. I invite you to take a look. I've found myself using it at work, home and play and use it from such mundane tasks as packing luggage items to coordinating my blog backlog.
Take a peak, you'll be glad you did.
