Perform a root cause analysis
Perform a root cause analysis by answering the questions in checklists
A checklist consists of a list of questions that define the possible root causes for a defect. You can answer the questions in checklists to identify the root cause of a defect. As you complete answering the questions in the checklists, you can provide comments about why you have provided a specific answer. Additionally, you can assign a resource to work on a question after you provide your answer. When you know the root cause, you can develop the relevant corrective actions and preventive actions.
Note
Before using checklists to perform a root cause analysis, the Quality manager must create the checklists for you in the Quality Master Data library, and add chapters, questions, and sub-questions to it.
