令和7年度 ITパスポート試験 問7
This question's explanation and your answers so far.
解説
問 7
Incorrectア
CRM (Customer Relationship Management) is a management approach and system for managing and strengthening relationships with customers over the long term to raise satisfaction and sales. It has nothing to do with the prior verification of a new concept, so it is incorrect.
- イ
正解 The correct answer is イ, PoC. PoC (Proof of Concept) refers to an activity of testing on a small scale, before full-scale development begins, whether a new concept, idea, or technology can actually be realized, in order to verify its effectiveness and feasibility. This matches the question's description of “verification carried out in the stage before development, aimed at demonstration,” so イ is correct.
Incorrectウ
RAS (Reliability, Availability, Serviceability) is a collective term for performance indicators used to evaluate the stable operation of a system. It is not a term for pre-development concept verification, so it is incorrect.
Incorrectエ
SLA (Service Level Agreement) is an agreement or contract between a service provider and a user that defines the service level. It differs from the empirical verification of an idea, so it is incorrect.
ここがポイント
- PoC (Proof of Concept) = an activity of verifying, on a small scale before full-scale development, the feasibility and effectiveness of a new concept, idea, or technology.
- Distinguishing confusing IT abbreviations: CRM = Customer Relationship Management, RAS = Reliability/Availability/Serviceability, SLA = Service Level Agreement.
