HI

I am new to this forum. :)

I started reading Rita book ver 7.  I am on chapter 5.   I have been doing the practice questions at the end of each chapter.

I read a lot on this forum about ITTO but i dont know how people are using ITTO to answer questions. 

Does anybody has an example of how to use ITTO to answer a question?  Most of the questions i answered was through common sense and I am not referring to ITTO diagram at all. should i worry? any example of how to use ITTO diagram to answer a PMP question?
