The Project Charter is a formal document that authorizes the existence of a project and provides the project manager authority to allocate resources. It gives the high-level project goals, objectives, and stakeholders. The project charter is usually created by the project sponsor or initiator and addresses the project's purpose, measurable objectives, high-level requirements, and the project manager's authority. It is essential to establish consensus among stakeholders, communicate expectations, and provide a basis for decision-making.

Develop Project Management Plan is a process that defines, prepares, and coordinates subsidiary plans to create a holistic project management plan. It is a comprehensive document that details the entire project scope, cost, schedule, risk, communication, and other plans into one road map. The project management plan serves as a guide for project execution and control. It is a living document that is continuously updated throughout the project life cycle. This process ensures alignment between project objectives and strategies, as well as clarifying roles and responsibilities.

Direct and Manage Project Work is a process where the project manager and the project management team lead and perform the work required to achieve project goals. They implement approved plans, follow processes, and create project deliverables. This process also involves monitoring risks, managing issues, and ensuring timely completion of activities. It is crucial for the successful implementation of the project management plan and helps the project manager to deal with uncertainties, changes, and project constraints.

Monitor and Control Project Work is a process of tracking, reviewing, and reporting project progress to ensure that the project stays on course and within defined parameters. It involves comparing actual performance with planned performance, analyzing variances, determining if corrective action is necessary, and updating the project management plan. The main objective of this process is to maintain control over the project, ensuring that it meets the project goals and objectives, and provide stakeholders with accurate, timely, and relevant information.

Close Project or Phase is a process that finalizes all activities across all Project Management Process Groups to formally complete the project, phase, or contractual obligations. This process ensures that all project work is completed, lessons learned are documented, resources are released, and final project deliverables are accepted by the customer or sponsor. It is essential for ensuring that project success is recognized, stakeholders are satisfied, and valuable knowledge is captured for future projects, preventing the loss of critical information.

Develop Project Charter is a crucial process in the Integration Management area, where the project's purpose, authority, and preliminary scope are documented. The project charter is a formal document that authorizes the project's existence and gives the project manager the necessary authority to allocate resources and make strategic decisions. This document includes key project stakeholders, project objectives, success criteria, high-level risk, and constraints, and it sets the foundation for the entire project, as well as acting as a reference point for subsequent project planning and management activities.

Develop Project Management Plan is a process in which a comprehensive and integrated plan is prepared to guide the execution, monitoring and control, and closure of a project. The plan outlines various aspects of project management such as scope, schedule, cost, quality, resources, communications, risk, and procurement. It also integrates and consolidates subsidiary plans like scope management, schedule management, and cost management. The Project Management Plan is a living document that is updated and refined throughout the project as changes occur, requirements are clarified, or new information is uncovered.

Manage Project Knowledge is a critical process in Integration Management that involves creating, capturing, sharing, and retaining relevant knowledge achieved throughout the project lifecycle. This process ensures that valuable experiences, lessons learned, and best practices are documented and made available to team members and other stakeholders, enabling them to benefit from past experiences and avoid making the same mistakes. It also helps to enhance the decision-making capability of the project manager and the project team by providing systematic access to relevant information and reducing the impact of knowledge loss due to staff attrition.

Perform Integrated Change Control is a process for reviewing and approving any changes to the project scope, schedule, and cost baseline as well as assessing the impact of change requests on other aspects of the project, such as quality, risk, and procurement. This process aims to ensure that changes are introduced systematically, evaluated thoroughly, and approved by the appropriate stakeholders before being implemented. It includes the use of change control board (CCB) to review, analyze, and decide on the approval or rejection of change requests. It also facilitates the coordinated communication of approved changes to all affected parties, to maintain the integrity and consistency of project documentation.

Validate Scope is a process in Integration Management that confirms the project deliverables' compliance with the project requirements and stakeholders' expectations. It focuses on the formal acceptance of completed project deliverables by the stakeholders, ensuring that they meet the pre-defined requirements, specifications, and quality standards. This process is carried out periodically throughout the project or at the end of specific project phases to monitor and control the project scope and avoid scope creep. The Validate Scope process also helps to identify any improvements, adjustments, or further requirements that may be needed in future project phases, enabling proactive scope management and enhancing stakeholders' satisfaction.
