“Business people can see features or apps, so getting funding for those is easy,” he continues. “But they don’t see the vast architectures underneath that support them, connecting systems, teams, and data to each other. And underneath that is something extraordinarily important: the systems that developers use in their daily work to be productive.

When people say, “It’s inevitable that a large program will have bugs,” they don’t mean inevitable in the sense, “It’s inevitable that cars will have accidents.” What they mean is, “We don’t have the proper software engineering techniques to root out all defects so we’re not even going to attempt to remove them all—and we’re not going to improve the techniques either.”

— Adam Barr, The Problem with Software

Since failure can arise from many causes, product processes typically demand consensus by many people, each expert in a separate cause of potential failure. Such consensus stifles great design in several ways. First, each expert watchdog is paid to avoid mistakes, not to make great things happen.

Many software researchers advocate rather than investigate. As a result, (a) some advocated concepts are worth far less than their advocates believe, and (b) there is a shortage of evaluative research to help determine what the value of such concepts really is.

Dealing with complexity is the most important challenge in software design.
