In my company, we plan our develpment work with scrum.

We track progress using post-it stickies on a big whiteboard, and it works great. It is my understanding that's kind of standard. We are just one location, so we don't need or want to do this electronically.

But to our (and the Q/A rep's) annoyance, the sticky notes begin to fall off the whiteboard after a week or two, or even sooner if you stick them on top of each other. I've experimented with extra tape on the stickies. That helped, but it also ruins the whiteboard.

So I am looking for a pragmatic and preferably low-cost alternative. Are some post-it brands better than others? Or do you have another solution for a scrum board does not suffer from this?
