I like your goal

“To engage the maximum number of people and consider the maximum number of ideas and implement the most impacting of those ideas in the fastest amount of time with the least amount of cost.”

All organisations have a bottleneck that regulates how many ideas get implemented. Often this is simply a question of the amount of peoples time dedicated to implementing the changes. I am a big fan of GE “work out” as a mechanism to engage people in fixing their own problems.

In this instance though, I guess the bottle neck is the fact that the suggestion box is placed by the gents bathroom.

Probably not the best place.
