The best way to lower development costs is to hire great engineers: they don’t cost much more than mediocre engineers but have tremendously higher productivity. However, the best engineers care deeply about good design. If your code base is a wreck, word will get out, and this will make it harder for you to recruit. As a result, you are likely to end up with mediocre engineers. This will increase your future costs and probably cause the system structure to degrade even more.
