A map for decisions, drawn by someone who already knew the answer.

means A diagram that uses boxes and arrows to lay out the steps and decision points of a process from start to finish.

from A compound of 'flow' (the movement or progression of something) and 'chart' (a map or graphic display of information), 'chart' itself tracing back through French 'carte' to Latin 'charta,' meaning a sheet of papyrus or paper. The flowchart as a technique emerged in the early 20th century among industrial engineers mapping manufacturing processes, then was adopted by computer programmers in the mid-1900s to sketch the logic of a program before writing code — boxes for steps, diamonds for decisions, arrows showing the flow.

origin
Industrial engineers used it before programmers stole it
shape rule
Diamonds mean decisions, rectangles mean no thinking required
dirty secret
Often drawn after the code, to justify it
infinite loop
Every bad meeting is one with no exit arrow
