The collapse of complex software

Nolan Lawson:

Anyone who’s worked in the tech industry for long enough, especially at larger organizations, has seen it before. A legacy system exists: it’s big, it’s complex, and no one fully understands how it works. Architects are brought in to “fix” the system. They might wheel out a big whiteboard showing a lot of boxes and arrows pointing at other boxes, and inevitably, their solution is… to add more boxes and arrows. Nobody can subtract from the system; everyone just adds.

Nolan posits the center cannot hold and the current market shift from bull to bear might help bring the collapse of complex software. But it’s never that simple, is it?

One thing working in complexity’s favor, though, is that engineers like complexity. Admit it: as much as we complain about other people’s complexity, we love our own. We love sitting around and dreaming up new architectural diagrams that can comfortably sit inside our own heads – it’s only when these diagrams leave our heads, take shape in the real world, and outgrow the size of any one person’s head that the problems begin.
