It truly does depend on the setting, industry, etc. In manufacturing
production, there’s no reason to not get well above 50%. In offices, 40%
starts being respectable unless the org has implemented cross-functional
work cells, technology solutions, sustainable pull systems, work
segmentation, etc. (Most pre-improvement office value streams hover in the
5-10% range.) In many patient care settings, you can get above 50% fairly
Bottom line: Begin where you’re at, seek 50% gains with every improvement,
and never stop.
