So sang Pink Floyd in 1979 on their Christmas number 1 single Another Brick in the Wall Part 2 from their album The Wall. It was a protest against rigid, didactic education.
During the early start of my professional career, I gave a lot of value to get things done fast. I was an impatient operator whose only focus was execution with acceptable results. Now, ‘acceptable’ is very subjective word that can have a lot of different meanings depending of the one who use it. Later I found out that acceptable results often lead to rework.
