Common mistake
- •"Simple" and "easy" are not perfect synonyms: a surgical procedure can be "simple" (one-step protocol) but not "easy" (requires years of training).
- •A magic trick can be "easy" (learned in 5 minutes) but not "simple" (it has many complex steps).
Trick to remember it
- •Diagnostic question: is the issue complexity (many parts or layers)? = not simple.
- •Is the issue required effort (skill or time)? = not easy.
- •Something can be simple but difficult, or easy but complex, they are different dimensions.
Quick rule
- •"Simple" = no complexity, no extra parts.
- •"Easy" = no effort, no difficulty.
Did you know?
"Keep It Simple, Stupid" (KISS) is a design principle attributed to the US Navy in the 1960s. Engineer Kelly Johnson formulated it so that complex systems could be repaired by an average mechanic in combat conditions, without specialized tools. The principle underlines that COMPLEXITY is the enemy of reliability, not difficulty. A system can be difficult to design (not easy) but must be simple to operate and repair (simple). "Keep It Easy" would not have the same meaning or impact, because the problem was not the mechanics' effort but the too many internal parts and layers of the systems.
