Get approval of the purchase order for the correct replacement first, while the decision-makers still have a crisis mentality about the problem. Then get the approval for the temporary fix. But note that purchase orders can be cancelled. To prevent this:

  •  Develop a total cost of ownership comparison of the two fixes.
  • Develop a disposal, re-use, or resale plan for any expensive assets used in the temporary fix.
