Most stakeholders don't understand software-development, development cycles, or even SCRUM (the most known collaboration framework for software development). It always amazes me how managers and even seasoned developers do not understand these things. They don't understand estimates, roadmaps, task division, the value of software architecture nor exploration, nor just how complex it is to write software.

This also leads to them not understanding the tools used to manage the process, the developers, the software, nor the outcomes.

Everyone just wings it.
