Final answer:
To address concrete defects in a construction project, the project manager should first look into the Issue and defect management database to determine the best course of action based on past incidents.
Step-by-step explanation:
When facing a defect in a construction project, it's critical to consult organizational process assets that provide guidance on handling such issues. In this case, B Issue and defect management database would be the most relevant asset to reference first. This database likely includes records of similar incidents, their causes, and the remedial actions that were taken. It would serve as a valuable resource for understanding the problem at hand and determining the best course of action.
The project files from prior projects may also contain useful information but are secondary to the immediate concern of addressing the defect. The communication requirements are pertinent for handling coordination and informing stakeholders but not immediately applicable for identifying the defect cause. The process measurement database may provide data on performance but would not be specific to defect resolution.
