What is the process of research?
How do we know when we are
on the right track?
It’s not what you don’t know that kills you,
it’s what you know that isn’t so.
Tom deMarco
The research process
should concentrate on feedback.
Why is it so difficult to get feedback?
The engine of research is the PhD student.
The PhD student must be distant enough
from anyone around him.
Real feedback comes from interested people.
