The difference from project management I understand, but a lot of what you described regarding keeping the progress going seems to be a SCRUM master's job. Would you say that is also management? Its all a bit fuzzy to me, because for example these are still engineering tasks for me:

>- Saying yes/no to projects

>- Medium term planning, resource balancing

>- Helping to set team vision and mission

>- Keep up to date and abreast with what’s happening in the org, filtering info to the team (down)

>- Often acting as a tie breaker for decisions (including technical)

>- Often involved in steering technical design and solutions

I think it should be done by senior engineers organically as engineering is a social activity. No one person can achieve greatness and to me an engineer becomes a senior engineer not by being a brilliant coder (for example) but by understanding that the job is to solve problems.
