Same question on ITPEC: Apr 2025 Q96
Which of the following is a term that represents the practical verification of a new concept or idea before development?
Explanation
PoC — proof of concept, a small practical test of whether a new concept or idea can actually work, done before full development.
Before committing budget and time to development, a PoC tries the idea on a small scale, often with real data or in a real setting, to check that the technology works and that the expected effect appears, for example whether AI image recognition reaches the accuracy an inspection line needs. If it fails, the idea is revised or dropped at low cost; if it succeeds, it gives the evidence for going ahead.
Answer (c)
Why not others:
- •(a) CRM — customer relationship management, managing customer information to build long-term relationships
- •(b) KPI — key performance indicator, a measure of progress toward a goal, such as the monthly number of new customers
- •(d) SLA — service level agreement between a service provider and its customer on the level of service, such as availability or response time
Key rule: A PoC answers "can this idea work?" cheaply before development; a KPI measures progress and an SLA fixes service levels once something is running.
