The term reduce is from the late 14c., reducen, "bring back" (to a place or state, a sense now obsolete), also "to diminish" (something), from Old French reducer (14c.), from Latin reducere "lead back, bring back," figuratively "restore, replace," from re- "back" (see re-) + ducere "bring, lead." 

How do we reduce the complex to simple? Occam's razor is a great guiding principle in life and business. Simple is always best. Many processes are overly complex. Reduce the number of steps in processes if possible. Strive to reduce and simplify.
