* Micromanagement of skilled people. * Over-investing when things have gone badly wrong, and being sluggish to invest in a team which is having success. * Hiring unskilled engineers to develop features which are meant to be reused by other teams. Bad or complex architecture leads to lots of workarounds and bugs, which destroy efficiency in other teams. * Not investing in fixing inefficiencies, instead just asking people to work longer hours.
