If a project manager continues to receive project-related work after the project has been released into production, it suggests that the project closure phase was not completed properly. The project closure phase involves several activities, including ensuring that all project deliverables are accepted, documenting the lessons learned, releasing project resources, and formally closing the project. If these activities are not completed, the project can remain 'open' in a sense, leading to continued work and inquiries.
References = The answer is based on standard project management practices and the importance of the project closure phase as described in project management literature. For detailed information, please refer to the CompTIA Project+ Study Guide and other official CompTIA resources. Specific references to the closure phase can be found in the CompTIA Project+ PK0-005 Cert Guide1 and the CompTIA Project+ Certification Exam Objectives2.

The project manager can use the survey results as an input for performance feedback for the project team members. Performance feedback is a process of providing constructive and timely information on the performance of individuals or teams in relation to project goals and expectations. Performance feedback can help to motivate, improve, and recognize project team members345 The survey results can be used as an input for performance feedback. Performance feedback involves analyzing and evaluating the performance of the project team and project management against the project plan, including identifying areas for improvement. The survey results can help identify these areas for improvement and provide feedback to the project team on their performance. Reference: CompTIA Project+ Study Guide Section 4.1.1

The project manager should use a Pareto chart to prioritize which defects to address for the product. A Pareto chart is a type of bar chart that shows the frequency or impact of different causes of problems or defects. It also shows a cumulative line that represents the percentage of the total frequency or impact. A Pareto chart can help to prioritize the causes that have the most significant effect on the quality of the product and apply the
80/20 rule, which states that 80% of the problems are caused by 20% of the causes.

A business case provides justification for undertaking a project, programme or portfolio. It evaluates the
benefit, cost and risk of alternative options and provides a rationale for the preferred solution. A business case
is essential for demonstrating the value of the project and securing the approval and funding from the
governance. A business case is different from a scope statement, which defines the project boundaries and
deliverables; a sponsor request, which initiates the project idea and seeks support; and a project charter, which
authorizes the project and assigns the project manager. References = CompTIA Project+ PK0-005

A finish-to-start relationship is a type of logical dependency between two tasks, in which the first task must be
completed before the second task can start. In this scenario, the document containing information about how
the new system will interact with other systems within the organization is a prerequisite for the configuration
of the system in development. Therefore, the document writing task must finish before the configuration task
can start, which is a finish-to-start relationship. References = CompTIA Project+ Study Guide: Exam
