If you check is not seller proposals only. It is procurement documentation too. On the other side, organizational project assessts is the only component related to procurement. So, you have all you need to conduct procurements.
The PMBoK is written from the owner perspective, so outputs are RfPs and inputs proposals.
Looking from the seller perspective, there is another project, owned by the seller, with input RfP and output proposal.
Have been on both sides.
But you also need to eventually obtain the selected vendors.
Sellers Proposal is thus at one point an output. And then later becomes an input.
Say I need to build a wall. I have done the make/buy analysis and decided to outsource. I will need proposals from invited vendors. That’s an output at one point in the conduct procurement. Then later I will have to analyze these proposals to select a vendor. At this time it’s an input. I am wondering why PMBOK didn’t capture this nuance.
OUPTUT means AFTER doing this you GET that.
In the first instance after advertising and conducting bidders conference.
INPUT means BEFORE you do this you NEED that.
In the second instance before you do proposal evaluation.
as I see it:
the output of a make/buy analysis is not any proposal, it is the decision to buy and further down the road the procurement documents including the RfP. A proposal is always - as the name suggests - proposed by someone, in this case the sellers who are asked to bid. So any proposal can only be a input for the buyer/owner, or they had to propose to themselves.
Make or buy isn’t really a part of the question though.
What I was trying to arrive at is say you want to outsource something. (Won’t call it a wall and won’t reference make or buy as an activity to arrive at decision to outsource).
The emphasis is sellers proposal. At one point it’s an output of an activity. At another point it’s also an input to another activity.
Advertising and bidders conference in the first
Proposal analysis in the second.
I am hoping this explanation is clearer now.
Next is wondering if there is any possible reason why PMBOK didn’t capture it as both.
Sergio made good points.
According to PMBOK the bid documents are an output of plan procurement though. Not conduct procurement.
The sellers response is same as the sellers proposal. And this is what you get AFTER you issuing out your RFP or RFQs
Since it’s coming after at this point based on the general definition of output (the sellers proposal) is also an output although PMBOK doesn’t also capture its dual nature.
