Points to consider
Do the selected suppliers have viable, credible proposals fully capable of meeting the requirement?
Have the right number of suppliers been selected taking account of the need for competition, VfM, and the costs falling to both sides during the rest of the procurement?
Do not include suppliers that have no viable solution simply to introduce a spurious appearance of competition
If few proposals were received and/or only one supplier is deemed capable of meeting the requirement, it could be because the requirement is too complex or suppliers do not consider the project to be achievable. Decide whether the procurement should continue in its present form.
