Which activity verifies a system's quality by identifying and fixing defects before deployment?

• A. Testing a System for Errors
• B. Designing the Components of the System
• C. Obtaining System Requirements
• D. Constructing a Personal Health Record System

Answer: (A)

Testing a system for errors is the activity that verifies quality by systematically running the software, comparing actual results to expected results, and capturing defects so developers can fix them before the product goes live. This pre-deployment defect discovery is how you ensure reliability, data integrity, and patient safety in a healthcare IT context. By exposing issues early, you reduce the risk of failures after deployment and increase confidence that the system meets its requirements. Designing the components of the system focuses on how the architecture and modules will be built and interact, not on evaluating overall quality before release. Obtaining system requirements is about gathering what the system should do and the constraints it must meet, not testing its behavior. Constructing a Personal Health Record System describes the actual creation of the software, not the verification process.
