Do you know which models you are willing to accept and which diplomats can provide those? If not, I think you should run a rfp first to narrow down the possibilities. Then you can run an auction with a line item for each different model you are willing to accept.
Sorry, I think the spellchecker changed a word with "diplomats", but I think you probably understand the intended meaning!
How would it be if you asked suppliers to bid on a monitor that meets or exceeds your minimum spec and maybe invite bids on different specs i.e. lot 1 is a 17" monitor, lot 2 is a 19" etc ?
So building an RFx that lists your Minimum Equipment Level / Minimum Spec and it may include items like
- Aspect ratio
- Response time
- Refresh rate
Minimum connection spec
(I'm not a tech guy, so there may be more or less items to your spec you'd want to include)
The suppliers could confirm if they meet or exceed your spec and confirm the spec details. Asking if they meet or exceed will allow suppliers to demonstrate how they add extra value.
You may want to include additional qualitative questions that deal with warranty and repair process too.
I've just been asked to set up an auction in the manner that Chen described; supplier can provide more than one product that meet our requirements and we want them to bid with both options in a single line in the auction. We also want visibility to which product they are bidding on, so we came to the same conclusion of having multiple IDs for that supplier.
In our scenario, we have a set up like this:
Supplier A - Product 1 - exceeds our requirement, cost is higher
Supplier A - Product 2 - meets our requirement, cost is lower
Supplier B - only 1 product - meets our requirement
Supplier C - only 1 product - exceeds our requirement
We suspect there may be a point where product1 from Supplier A becomes very competitive against the other suppliers products. We also want the flexibility to select Supplier A-Product 2 if the pricing for that item leads to considerable savings.
Is anyone else structuring events in this way? Any other options? We do not want to compare two unique line items as only 1 of our suppliers has multiple products.
You could also let supplier A bid on the primary item and use alternate bidding for the other item. The alternate item would not be used in the ranking, so that might preclude its use, but an idea.
