what six sigma tool do you actually use the most?
i've been thinking about how different six sigma can look when you're learning it vs actually using it at work...
you learn a pretty big toolbox during training, but realistically i don't think most people are pulling out every single tool on a regular basis.
for me, process mapping is probably the one i keep coming back to the most. it's simple, but just seeing how a process actually works vs how people think it works can uncover a surprising amount of stuff.
i also find myself using some of the simpler root cause tools way more often than the more advanced statistical ones...
for those who use six sigma/process improvement at work, what tool do you actually use the most? and is there anything you learned during your belt training that you almost never touch anymore?
