Purchase system: control procedures (ordering stage)

Good evening, Sir.

Sir, could you please tell me whether the listed control procedures below are suitable for achieving the control objectives in the purchase system of internal controls at ordering stage:

Ordering stage (placing an order)

Control objectives
1.The orders have been placed
with a supplier who could provide
quality goods, can be relied upon,
and has fair pricing.

Control procedures
1. Orders should be placed with a supplier from the approved supplier list.

In addition, can a different control procedure satisfy the same control objective? May I have a guidance on that?
