Source of my problems: design issues 5% architecture constraints 5% language shortcomings 1% mental blocks 5% personal time management 4% personal energy 5% communication with others 75% I waste more time just trying to figure out what others are trying to say, sometimes in person and by voice, but mostly in writing. For most emails, I have to click "reply" or call back simply because what you're trying to tell me is…
Overwhelmingly, projects I've been involved in that failed or nearly failed did so because of basic communication problems - misunderstanding someone, not clarifying, not getting enough detail, making assumptions, etc. Yet these skills are hardly ever taught anywhere. Hard tech skills in schools, certification progams, etc. all cover less than half of what makes a truly useful developer.
