In 50′ and 60′ input data for programs from those years were written on paper tapes or punch cards. Writing code, compiling and testing loop took from a few hours to even few days. It was the beginning of programming we know it.

At this time Dijkstra started his discovery. He conceived the algorithm called his name. He also noticed that programs become too complicated to be fully understood by one person. A single developer can miss something, forget or misunderstand. This situation could cause that program could work incorrectly. The program’s invalid behavior could be noticed after some time. In industries like financial or telecom it could lead to high costs, be hard to debug and fix.
