Re: "no business plan"
I don't think the OP was slagging off the planners. I think he was saying they are different roles, with difference skillsets.
If that's what he is saying, then I agree.
There are a lot of roles, many I'm not good at. Phone support, sales... there are reasons I don't do these things, but I don't badmouth those who do. If not for them, I wouldn't get a paycheck either!
