Dear Friends,

I some confusion in process charts mentioned in PMBOK ed. 4, for example

To determine budget (7.2) one of input is 'contract document'. Contract document is out put of process 'conduct procurement' (12.2). Now one on input of conduct procurement is Plan procurement (12.1). So process flow becomes 12.1 then 12.2 and then 7.2.

One of input of Plan procurement (12.1) is 'cost performance baseline'. Cost performance baseline is out put of determine budget (7.2) so 12.1 can not be completed unless 7.2 process is completed.
