The BEST way to coordinate management of multiple related projects is to establish a program. A program is a group of related projects that are managed together to achieve specific strategic business objectives. References: CompTIA Project+ Study Guide Section 2.2.1 The organization should establish a program to coordinate management of multiple related projects. A program is a group of related projects, subprograms, and program activities that are managed in a coordinated way to obtain benefits and control not available from managing them individually. A program can help to align multiple projects with strategic goals, optimize resources and risks, and deliver value to stakeholders.

The percentage of risk investments with defined business cases is a metric that measures how well the information security program aligns with the operational objectives of the organization. It indicates how many of the security-related investments are justified by a clear analysis of the expected benefits, costs, and risks, and how they support the business goals and priorities. This metric can help the organization optimize its security spending, demonstrate the value of security to the stakeholders, and align the security strategy with the business strategy1. References = Performance Measurement Guide for Information Security, Section 3.2.3, page 16; Key Performance Indicators for Security Governance, Part 1, Section 3, page 3.

The project manager should have generated a contingency plan first to alleviate the impact of this issue prior to deployment where a major malfunction resulted in an inoperative product condition during a code implementation. A contingency plan is a plan that outlines alternative courses of action or strategies to deal with potential problems or risks that may occur during a project. A contingency plan can help to prevent or minimize the negative impacts of unforeseen events or issues on the project objectives and deliverables and ensure business continuity and stability.

The project manager and team should review assumptions and constraints for input to the risk register during the planning phase of a project. Assumptions are statements that are considered to be true for the purpose of planning, but may or may not be valid in reality. Constraints are factors that limit the project scope, time, cost, quality, or resources. Both assumptions and constraints can introduce risks to the project, which are uncertain events or conditions that can have a positive or negative impact on the project objectives. The risk register is a document that records the identified risks, their causes, impacts, probabilities, responses, owners, and status. Reviewing assumptions and constraints can help the project manager and team identify, analyze, prioritize, and plan for the potential risks that may affect the project12.
The other options are not the correct activities that the team should do during the planning phase of a project.
Identifying and assessing stakeholders (option A) is an activity that is done during the initiating phase of a project, not the planning phase. Stakeholders are individuals or groups that have an interest or influence in the project, and their identification and assessment is important to define the project scope, objectives, and success criteria, and to establish a communication plan12. Holding daily status meetings (option B) is an activity that is done during the executing and monitoring and controlling phases of a project, not the planning phase. Daily status meetings are short and frequent meetings where the project team members report on their progress, issues, and plans for the next day. Daily status meetings can help the project manager track the project performance, resolve problems, and communicate updates12. Removing access and planning the project sign-off (option C) is an activity that is done during the closing phase of a project, not the planning phase.
Removing access is a security measure to ensure that the project resources do not have access to the project systems, data, or assets after the project is completed. Planning the project sign-off is a process to obtain the formal acceptance and approval of the project deliverables from the stakeholders and customers12.

Explanation
The project manager should notify the functional manager that resources are released after completing a project successfully in a functional organization. A functional organization is a type of organizational structure where employees are grouped by their functions or specialties, such as finance, marketing, or engineering. In a functional organization, the functional manager has more authority and control over the resources than the project manager. Therefore, the project manager should inform the functional manager when the resources are no longer needed for the project and can be reassigned to other tasks or projects.
