TOPIC: Planning processes

Hi,

Can anyone let me know what is the best approach to plan the processes?

What i mean is:

While planning for a project, should we plan in the following order

1. Planning scope,
2, Planning time/schedule
3. Planning Cost
4. Planning quality
5. Planning Risk

or

1. Planning Risk,
2, Planning time/schedule
3. Planning Cost
4. Planning Scope
5. Planning Quality

I understand these processes can happen in parallel, i just want to know the best approach

Thanks,
Saravana
