A traceability matrix is a document that maps the requirements of a project to the deliverables, test cases, and
changes that are produced to meet those requirements. It helps the project manager to track the origin, status,
and impact of each requirement throughout the project life cycle. A traceability matrix can also identify who
requested or approved each requirement. Therefore, the project manager can use the traceability matrix to
identify who requested the specific item that caused the regression test to fail12.

The project manager should use synchronous communication methods if they prefer to have immediate contact
with team members. Synchronous communication is a type of communication that occurs in real time and
allows for faster response times and more interactive discussions. Examples of synchronous communication
methods include phone calls, video conferences, instant messaging, and face-to-face meetings. Synchronous
communication can help to build rapport, clarify doubts, and resolve issues quickly among team members.
Synchronous communication should be used when the project manager prefers to have immediate contact with
team members. Synchronous communication allows for real-time interaction and feedback, enabling faster
response times and more interactive discussions. References: CompTIA Project+ Study Guide Section 3.1.3

The system is lacking proper access controls if a third-party vendor was able to see secured project
information in a recently implemented system that resulted in a fine for the organization. Access controls are
security mechanisms that regulate who or what can view, use, or modify data or resources in a system or
network. Access controls typically involve authentication and authorization processes that verify the identity
and permissions of users or devices before granting them access. Access controls can help to protect data
confidentiality, integrity, and availability and prevent unauthorized access, misuse, or theft12

A dashboard is a visual tool that displays key project metrics and indicators in a single view12. A dashboard
can help a project sponsor to provide the latest project status information on a weekly executive call by
showing the project progress, budget, schedule, risks, issues, and milestones in a clear and concise way34. A
dashboard can also facilitate communication, collaboration, and decision making among project
stakeholders56. A dashboard should be reviewed and updated regularly to reflect the current state of the
project7. References = CompTIA Project+ Certification Study Guide8, CompTIA Project+ Certification Exam

A wiki knowledge base is a collaborative online platform that allows users to create, edit, and share information about a specific topic or domain1. A wiki knowledge base is best to use for storing lessons learned because it enables easy access, retrieval, and update of the lessons learned by project teams and stakeholders2. A wiki knowledge base can also support keyword search, version control, and linking of related documents3. A wiki knowledge base is different from a whiteboard, which is a physical or digital board that can be used for brainstorming, sketching, or presenting ideas; a content management system, which is a software application that allows users to create, manage, and publish digital content; and a workflow platform, which is a software tool that automates and streamlines business processes4.
