The 8 Subtle Wastes

While the more obvious forms of the 8 Wastes are more readily noted, the greatest opportunities can be found hiding in the 8 Subtle Wastes:


Intermittent pauses prevent us from reaching an effective flow, either mentally or physically. Your system should allow you to keep a steady rhythm until it’s time for a proper break.


Adjustments are often necessary in existing processes, but the long term goal should be to get it right on every first attempt.


Even if nothing has to travel a significant distance, transfers can easily lead to a similar problem, if not worse.

Much like tweaking, everything should flow and fit right the first time. It is distracting and draining to regularly monitor and shift to correct for poor fits.


It is human to make mistakes, but systems should compensate for and prevent our errors. Targeting mistakes offers far more opportunities than waiting to fix the resulting defects.

People cannot utilize or learn the necessary skills and abilities if they lack clarity, of vision or situation.
