Answer: begins with evaluating potential vendor proposals
Step-by-step explanation:
A new-task buying in business refers to when a company is buying a good for the first time and so have no experience in the matter and do not have selected vendors that they can trust more in this endeavour.
In that case, the best first step would be to evaluate the proposals of different vendors so that the company can see which one would serve its needs best based on the different parameters that they have. They can then begin to source goods from that vendor after further scrutinization.
