I can see the value of a "Content Strategist" role in organizations, but the part of Scott Kubie's description that resonated with me is "Bulldog"; as in, someone who stays on people to get all the bits done on schedule.
Perhaps the image of a bulldog is a bit menacing, but tenacity is a handy skill in a project manager (to use a much less sexy job description- "Content Strategist" is so shiny and new!). There is a balance to be made between "just get something out the door" and "wait until everything is perfect", and having all of the parts be pretty good, or at least present.
In our new App World, users are accustomed to steady improvement of products, so go for incremental processes rather than all-or-nothing. Things get shipped.
Bring out some of your inner bulldog.
