解説
問 42
Incorrectア
An ASP (Application Service Provider) refers to a business (a service model) that provides application software functions to users over a network. It is not a document for agreeing on quality levels, so it is wrong.
Incorrectイ
An ISP (Internet Service Provider) refers to a business that provides internet connection services. It is not a document for agreeing on service quality, so it is wrong.
Incorrectウ
An RFP (Request For Proposal) is a document created by the ordering party to present the requirements of the system it wants to procure and to solicit proposals from vendors. It is used at the entry point of procurement, not for agreeing on quality levels after a contract, so it is wrong.
- エ
正解 The correct answer is エ “SLA”. An SLA (Service Level Agreement) is a document in which the service client (user side) and contractor (provider side) agree on the quality levels of the service provided — such as availability, response time, failure recovery time, and support scope — by setting specific metrics and target values. This directly matches the question’s description of something created to reach agreement between the client and the contractor on the service quality level.
ここがポイント
- An SLA is a document in which the service provider and user (the contractor and the client) agree on quality levels using numerical targets, and it forms the basis of SLM (Service Level Management).
- ASP and ISP are “businesses / service models,” and an RFP is a “request for proposal used during procurement”; distinguish them by the fact that none of them is a quality-agreement document.
