Most software design is lousy. Most software is so bad, in fact, that if it were a bridge, no one in his or her right mind would walk across it. If it were a house, we would be afraid to enter. The only reason we (software engineers) get away with this scam is the general public cannot see inside of software systems. If software design were as visible as a bridge or house, we would be hiding our heads in shame.
We would not accept a new house with sloping floors, holes in the ceilings, nails sticking out of the walls, and an outrageous price -- even if it minimally met basic needs. We would not be content with the explanation: "Well, it has a front door, which usually opens. You can find your way to the kitchen, but watch out for the nails. The holes in the ceiling don't really leak. And sure it ran 300% over budget, but houses often do." Rather than crooked floors, the software manifestations of poor design are redundancy, unnecessary performance bottlenecks, intertwined bugs that cannot be fixed, impenetrable code, and other ills. Unfortunately, we often accept software in just such a state. Regularly, companies release code like this to external and internal customers. And customers accept delivery. Businesses pay billions of dollars per year for this kind of software during mergers and acquisitions.
