Poor project management. It's very rare you see a company/team come up with a plan and stick to it, without deciding to randomly overhaul a bunch of stuff or add more features/complexity midway through. Then again, it's a close one. I'd say also one of the following may take it: How the site/app/program always seems to fall apart whenever the boss looks at it, or how the developers struggle to replicate said issues when testing it later. How in web development, every browser seems to have its own half assed idea about which features to implement and how to implement them, rather than just sticking to the damn spec and keeping it consistent with other browsers. The flavour of the week stuff, with developers constantly wanting to use the latest shiny framework. Or perhaps how many designers seem to act like they're making a painting rather than an application, with zero thought put into how it scales between sizes, how things may fit in a grid, how various conditions (like errors) work etc.
