Selecting the right vendor starts with knowing what you want and then finding the supplier that will get you what you want. Here's a breakdown of what this might entail:
Step 1) Understanding the requirement
Step 2) Generating the options
Step 3) Analyzing the options
Step 4) Selecting the best option
Step 5) Getting the decision to proceed
Informal vendor selection (Fast track)
Use this approach if you need to turn around a decision really quickly and you have the remit or necessary sponsor support to keep it informal.
Step 1) Understanding the requirement
Try to have the target budget identified. This may need to be challenged later depending on the criticality of the desired outcome.
Step 2) Generating the options
Contact them by phone at first to weed out the obvious mismatches. Once you've got a short list together send them your problem statement via email (or mail). Follow this up with a phone call explaining your time constraints and openly request their support. Be sure to share any information fairly across your vendors. (e.g. an answer to a question may need to be shared with the other vendors)
Set-up a demo day for all your vendors.
Step 3) Analysing the options
Create a score card with the selection criteria down one side in rows and the vendor options in the columns for assessment. The intention is to score each criteria out of five for each vendor (where 5 = 'excellent fit for purpose' and 1 = 'unfit for purpose').
Apart from the usual logistics (meeting rooms, diaries etc.) make sure you have briefed your assessors on the problem and the instructions for filling in the score cards.
Step 4) Selecting an option
Make sure the vendor demonstrations focus on addressing the problem statement. Collate the score card results. Add the scores up for each vendor and calculate the percentage of the maximum available. You can express this percentage as 'the estimated percentage match to requirement'.
Offset these percentages against the cost profile for each vendor. Try to identify the vendor with both the highest percentage match and the lowest price.
Discuss your findings with the other assessors (make sure you have consensus).
Step 5) Getting a decision to proceed
In part two we'll look at fast tracking this with little more formality.
