Confession Innovation or Confession Problem Solving.
The core idea here as Isak Bukhman puts it “problems are secret”, so we cannot ever solicit people to share their problems in public. It never works.
So create a confession booth, no need for an overly engineered one, but just enough to ensure we cannot spot whose problem it is and who is trying to solve it. As usual the problem goes through the regular series of problem solving stages of TRIZ.
I was even thinking of a series of confession booths like an assembly line.
One difficulty I foresee is continuity from stand to stand, but it can easily solved by grouping the stands in a circular fashion or forwarding a cryptic message to the next stand etc.
At the end of the booths we can even have a box for donations 🙂 for delivering a special prayer to Almighty Bob.
