I've been using a whiteboard to visualize client relation status.
________________Good______________ | | | | | | | | | |Cost____________|_______________|Revenue | | | | | | | | | |________________|_______________| Bad
Then we've been using logos of the customer + magnets to move them around the board.
This is an elegant way to visualize the client status. The upper right is the sweet spot where you would like all clients to be, and clients the lower left is those where you should end your relation.
Now we're a distributed team, so we need some web based tool to do this.
One could do it with an ordinary online drawing tool, for example https://sketch.io/sketchpad/, but it's not convenient to use for this purpose.
