9. It’s all about the biz

10. Hiring

11. Relative number of programmers

12. Relative number of programmers

13. Is it harder to find functional
programmers?

14. Is it harder to find good
functional programmers?

15. Relative number of programmers

16. Relative number of programmers

17. Good programmers only
matters for hard problems

18. Functional programmers are a
little more expensive (on
average)
(citation needed)

19. But you need fewer to do the
same work
(citation needed)

20. Code Quality

21. # of bugs is correlated with
lines of code
(defect density)

22. Functional code is often
significantly smaller
(by orders of magnitude)
(citation needed)

23. ∴ FP results in fewer bugs
(citation needed)

where other methods have
failed
(citation needed)
