Dear Kevin,
At the outset thank you very much for your quick reply. I am extremely grateful to you for the same. In the mean time from your reply i have made following observation
1. As per as PMBOK Process Chart is Concerned, it is a broad generic chart as defined in Page 173 of PMBOK Guide. It does not goes into the ACTION STEPS of each Process area.
2. Moreover, as per as understanding of the concept is concerned, Understanding of each and every individual could be different from each other. For instance, if i take the first case cited by me in the above few lines, we at our work place never take approval of the team member in preliminary schedule. We consider it unnecessary workload. I am currently working in a multi billion dollar World Bank Project and we donot have any such system of taking approval from team member in preliminary schedule. Hence on the basis of my experience in WB if i write PMP exam, i shall be declared fail since my reply to the question will be different from the above answer. So how understanding ITTO and KA is helping me to know the PMI Action steps for PMP Process which is very much critical for me to pass the exam.
Looking forward
Joydip
