The best way to improve deliverable quality is to embed continuous feedback and inspection throughout the process, rather than relying solely on late-phase inspections. By breaking the project into iterations (an Agile principle), the team can apply automated testing early and often, while also using retrospectives (quality improvement sessions) to continuously improve.
According to the Agile Practice Guide (Chapters 3 and 5), Agile frameworks encourage frequent quality checks, test automation, and continuous integration to reduce defect rates. This approach aligns with "Build Quality In," a principle emphasized in both the PMBOK Guide (Seventh Edition) and lean/agile practices.
Option A addresses training but lacks ongoing quality integration.
Option B is reactive and too late in the process.
Option C is better than B, but quality auditing alone is not sufficient.
