This is the initiation phase of a project where a project charter is formulated. The project charter is a document that formally authorizes the existence of a project and provides a project manager with the authority to apply organizational resources to project tasks. The charter includes information such as project purpose, measurable project objectives, high level requirements, project description, key deliverables, project boundaries, and other crucial information. This charter is the basis of a common understanding of the project, its scope, and its deliverables among all stakeholders.

This involves creating a comprehensive plan that outlines how the project will be executed, monitored, and controlled. The Project Management Plan includes all subsidiary plans from all knowledge areas (for instance, the Plan Scope Management, etc) and baselines. It contains strategies, tactics, and a clear roadmap for project completion. It serves as a guide that is followed throughout the project lifecycle.

This is the phase where the project team carries out the plan. It is during this stage that deliverables are developed and completed, often requiring a team of people working together. In Project Integration Management, the project manager coordinates all the efforts to keep the project on plan, and to respond to any issues as they arise. Good execution is a sign of good project management and helps ensure that the project will stick to its timeline and deliver all outputs as planned.

This is the chronic phase of the project where the project's performance is observed and measured regularly to identify any variances from the project management plan. In this phase, careful monitoring and controlling are performed to ensure that the quality of deliverables is meeting the standards, the scope of the project is not changing, the costs incurred are within budget, and the project is going to be completed on time.

This is a crucial final step in Project Integration Management that formally completes and finishes all project-related activities. It involves the transfer of finished deliverables to their respective recipients, the assessment of project performance, documentation of lessons learned, release of project resources, and the official termination of project work. The closing phase is critical because it verifies that the work and deliverables were completed satisfactorily and that the project objectives have been met.

Direct and Manage Project Work focuses on executing the tasks defined in the project plan to achieve the project's objectives. This includes directing and managing the work necessary to complete the defined project scope and deliverables. It involves tracking, reviewing, and reporting the progress to meet the performance objectives defined in the project management plan. This process aims to provide overall management of the project work, including the managing, executing, and making adjustments as needed to meet the project objectives.

Manage Project Knowledge involves using existing knowledge and creating new knowledge to achieve the project's objectives. It involves identifying, capturing, storing, and sharing knowledge to improve project outcomes. The main components of this process include creating a knowledge management plan, setting up and managing a project knowledge base, capturing and documenting lessons learned, and using knowledge management tools and techniques. This knowledge management process can help avoid repeating past mistakes and leverage existing knowledge to enhance project performance.

Perform Integrated Change Control is a process in project integration management that focuses on formally reviewing all change requests, approving changes, and controlling changes to the deliverables and organizational process assets. Its purpose is to ensure that only approved changes are implemented in the project. This process involves review, analysis, approval, or rejection of the changes in scope, cost, schedule, and quality of the project, which could impact the project's objectives and deliverables.

Monitor and Control Project Work involves tracking, reviewing, and reporting the progress to meet the performance objectives defined in the project management plan. The main benefit of this process is that it allows stakeholders to understand the state of the project, the ability to affect change to the baseline, and continued business justification.

Close Project or Phase involves finalizing all activities for the project, phase, or contract. This process is performed to formally complete the project or a portion of the project and includes the necessary actions to close each project or a project phase. Closing a project or phase is crucial for organizational learning and knowledge transfer. This process ensures that the project is officially concluded and lessons learned are documented for future reference.
