In Quality Assurance, what is provided as proof of work performed?

In the context of Quality Assurance, documentary evidence of maintenance records serves as proof of work performed. These records document the specific activities, tests, inspections, and maintenance tasks completed during a project or on equipment, which demonstrates compliance with established standards and procedures. This documentation is critical for verifying that the work was done correctly and meets quality expectations. It also provides traceability and accountability, allowing auditors or stakeholders to confirm the quality assurance processes have been followed.

Other options do not fulfill the role of direct proof of work in the same way. Project timelines and deadlines outline planned work but do not show completed actions. Employee attendance sheets indicate who was present but not the quality or completion of their work. Training manuals provide guidelines and instructions but do not serve as evidence of specific tasks performed or their outcomes.
