Studies has shown that, on average, developers produce between
50 and 100 lines of code a day. And that
might not seem much. Why, why only 50 to
100 lines of code in a whole day? And the
answer is because coding is not everything. When you
develop a system writing code is not the only thing
you have to do. It's not the only activity that
you have to perform. And that's a very important point.
