Dear all,

I am currently reading the excellent file "00_PMP_Notes_Chowdary_Anil.xlsx" available on this website.
I stumbled upon something:

" Estimate Costs [...] is performed after Define Scope, Create WBS, Define Activities, Estimate Activity Resources, and Estimate Activity Durations."

In the PMBok, it seems being described as a sequencial process. But "Estimate Activity Resources" essencially depend on the amount of ressources the PM is willing to spend on the activity to make it quick or slow.
