This is a basic difference between good and bad planning. In bad planning, it is routine to leave problems, challenges, and unknowns to be figured out later. That’s how the Sydney Opera House got into trouble. In that case, Jørn Utzon did eventually solve the problem, but it was too late. The budget had exploded, construction was years behind schedule, and Utzon was ousted with his reputation in tatters. In many projects, the problem is never solved.
