will yield 80% of the results, but constraint management says that there are
few things you can do to have a significant impact; the rest have a minimal
impact. The 80/20 percentage changes to 99/1.
To see if you are working on the constraint, look at the history of net
profit and return on investment. If profitability is constantly rising, the constraint
is always being elevated. If your profits are not growing, you are not
paying attention to the constraint. You can ignore it, but it will not ignore you.
