stack rank ideas by importance
Placing a importance high, med, low is great. But too often you get individuals that will rank everthing as "high" to force a priority on their ideas. Ideally it would be great if there was a way for product management to select a set of ideas and ask customers to stack rank them or assess priority of each idea based on a pool of points.
There are many techniques out there that help support this. For example, instead of stack ranking. Give every voter 100 points and ask them to apply those points to a group of ideas. This could be a curated set of Ideas PM is looking for feedback on or it could be all the customers submitted ideas. Having customers stack rank or vote with points on their ideas is great for large accounts that have generated over 5 ideas. Helps you understand what is important for that customer.
