…easy way out
One of the reason people could not be bothered to employ decision-making tools is that they are lazy,
simple as that, because it seems like complex tools gives us more accurate and credible soulution than the simple ones.
Take simple grid analysis for example, it is a straightforward tool that requires less effort than say...SMART and AHP.
So I think the seriousness of problem and severity of consequences dictate decision makers' choice of tools.
Does that sound like we are not making a robust decision if we were to use simple tools that leave big space for incorrectness and unreliability?
