For the past two years, XYZ Company has issued Requests for Proposals (RFPs) for event...

The primary risk XYZ Company faces when issuing a new RFP, after previously not selecting any supplier, is the potential reluctance of suppliers to participate again:

Suppliers may decline to respond because XYZ has issued RFPs twice in the past without selecting anyone: This is a significant risk as suppliers may perceive it as a waste of resources and time, reducing the pool of potential responses.

Procuring the app from a third party when it was not purchased from a supplier during the previous years could result in the firm exceeding its budget: Budget management is a concern but not the greatest risk.

XYZ may be forced to accept a proposal that does not meet its business requirements: This can be mitigated by clearly defining requirements.

XYZ's timetable might place an unreasonable burden on the ability of suppliers to prepare and submit responses: While timeline concerns are valid, suppliers declining to respond due to past experiences is a more immediate risk.

Therefore, the greatest risk is that suppliers may decline to respond because XYZ has issued RFPs twice in the past without selecting anyone.
