Thanks for the post!
I think these are excellent points. I've heard the first described as insisting that people who identify a problem bring a proposal for a solution. On one hand, it forces people to consider how a problem might be fixed and take a degree of ownership in the solution. A downside though is that some problems might not be raised as early, as some people might become aware of a problem before they are able to determine its cause and how to fix it.
As management still likely wants to be aware of issues, what do you think is a good approach there?
cheers,
p.s. I think your Markup formatting didn't correctly create lists -- they each have "1." rather than numbering properly.
