Software engineering has more to do with people than with software. Have you checked Peopleware? Also, perhaps The Phoenix Project could help as well.
I agree, that's why I'm asking this question. I think these particular books are mostly helpful to the junior engineer.
But it's hard to believe that from here on out the only thing that's left is to learn how to deal with people. Surely there's more to the software side of software engineering than what TPP and Code Complete have covered. Surely very experienced engineers have written books on software engineering that cover something more than entry-level knowledge. (Clearly, since I haven't found such books yet, there's a chance they haven't been written. But I find that hard to believe, considering the broad audience of software engineers that are interested in that knowledge.)
The perfect BA should be someone directly from a SE team but with more people skills and are willing to take the burden of that position. He should be expected to increase the efficiency of the WHOLE team by say 20%.
- A bunch of devs. - A BA exactly like you described. Usually 50% on one team. - QA lead, able to pull from the set of devs at will. Must have deep automation and QA skills. - A scrum person ( 20% on the team ) - a tech lead.
