Estimate Cost Process has a Tool (Vendor Bid Analysis), This is nothing but getting quotes from the Potential Vendor and include that in the cost.

The Question i have is, We shoud have an Input to get this informatioin from Procurement Knowledge area but there are no input from procuement for Estimate Cost process and we have a tool which might need this information.

On the contrary same information is requried in Define budget and this has an input of contract from Procurement knowledge area.
