解説
問 96
Incorrectア
The combination of ① the purchase cost and ② the delivery cost. ① is the payment for procuring the goods handled by the system, and ② is the logistics cost of delivering those goods; both are costs that accompany the sales business rather than costs of owning and operating the system, so neither is included in the TCO. Because it includes none of the TCO costs, it is wrong.
Incorrectイ
The combination of ① the purchase cost and ④ the hardware maintenance cost. ④ is included in the TCO, but ① is the procurement payment for the goods handled by the system, a business cost outside the TCO. Because it includes ①, which is outside the TCO, and lacks ③, which is within the TCO, it fails to list all and only the TCO costs, so it is wrong.
Incorrectウ
The combination of ② the delivery cost and ③ the software maintenance cost. ③ is included in the TCO, but ② is the logistics and business cost of delivering the goods, outside the TCO. Because it includes ②, which is outside the TCO, and lacks ④, which is within the TCO, it is wrong.
- エ
正解 TCO (Total Cost of Ownership) refers to the total amount of cost needed to keep owning a system, covering not only its introduction cost but also operation, maintenance, management, and disposal. Both ③ the software maintenance cost and ④ the hardware maintenance cost are maintenance (operating) costs for keeping the introduced sales management system running, so they are certainly included in the TCO. The combination that lists all and only the costs included in the TCO is ③ and ④, so the correct answer is エ.
ここがポイント
- TCO (total cost of ownership) refers to the total cost of keeping ownership of a system from introduction through operation, maintenance, and disposal; costs related to IT assets, such as hardware/software maintenance costs, fall within its scope.
- The purchase cost and delivery cost of the goods handled by the system are costs of the sales business itself; the key point is to distinguish them from the system's ownership cost (TCO), as they are not included in the TCO.
