Create WBS and determine team

According to Rita's book 7th edition, the team should be determined before creating a WBS.


I don't understand how it is possible to determine a team even before creating a WBS in a large project?


Any input would be appreciated.


Thanks,

Can you give reference/ page number

 It is on page 57

Here concept is  - work of create WBS requires - working staff (for planning)


It does not mean team required for execution, it will come after estimate activities resources.

That makes sense.


Thankyou Sir.
