The model makes use of preventive measures and regular service as well as updates such as Service

The repair model is the transference of risk to an insurance company that covers the costs of replacing the critical assets within your network. The drawbacks are increase in premiums after making a claim, high premiums anyway, down time while the insurance company is processing the claim, and claim may not pay what replacement costs are today.

Assets will typically cost much more than the original capital outlay that it took to purchase it long ago.

Repair costs can be very high and a decision to exercise this model should not be made in haste. There are also depreciation issues to deal with as well. In any case, this model should be the last resort because of cost and may be the most time consuming.

The repair model makes use of the acknowledged skills and abilities of the existing personnel. Knowing that assets have very specific dollar values assigned to them, the choice on how to manage the asset is based on the experience of the personnel.

Before incurring the cost for repair of an inoperative asset, check for maintenance agreements that may include the cost of repair or the actual repair itself. Nevertheless, the repair model should focus on the restoration of the downed asset to its working status within the network infrastructure. Keep in mind that after hardware costs, costs for the reloading or replacement of software can be a large cost factor as well.
