I honestly am wondering if the OP is in my flight, as this looks like our playbook almost exactly.

And we do pretty good with it. If you have the right number of bodies and skillsets available, this works.

That's a big if, and I'm willing to bet the playbook isn't always going to work if you don'thave it all. It's like baking a cake without an ingredient. It might work... or you might get sludge or a dense mess.
