What is the most comprehensive scope for QA/QC activities in a project?

• A. Spanning only the data collection phase
• B. Spanning only the reporting phase
• C. Throughout all phases
• D. Only during initial planning

Answer: (C)

Quality is built and verified across the entire project lifecycle, not just in one moment. If QA/QC happens only in data collection or only in reporting, issues can slip through in planning, processing, or analysis and then surface later, causing rework or unreliable results. By applying QA/QC throughout all phases, you establish quality objectives and standards at the outset, enforce proper procedures during data collection (calibration, sampling, chain of custody), implement validation and reproducibility checks during processing and analysis, and ensure complete, traceable documentation in reporting. This continuous span reduces risk, supports regulatory and stakeholder expectations, and leads to more trustworthy final deliverables. Limiting QA/QC to a single phase leaves those gaps that can compromise data integrity and overall project quality.
