Pick several metrics that are relevant to you (such as market size, revenue potential, chance of completing the project (and time it will take to complete), how interesting the work is, confidence in how good the idea is). Use each metric as an axis of a graph (it could be multidimensional) and then place each idea you have on that graph. For inspiration look at the BCG matrix: http://en.wikipedia.org/wiki/Growth-share_matrix http://en.wikipedia.org/wiki/Growth-share_matrix
