A project charter is a document that authorizes the project to exist within the organization. A project charter is the output of the initiation stage of a project, which involves identifying the problem or opportunity that the project intends to address, and defining the purpose, objectives, scope, and justification of the project. A project charter formally approves and initiates the project, and grants the project manager the authority and responsibility to manage the project. A project charter also identifies the key project stakeholders, roles, responsibilities, and expectations, and establishes the high-level requirements, assumptions, constraints, and risks of the project12. A project network diagram is a graphical representation of the logical relationships among the project activities. It shows the dependencies, sequence, and duration of all the activities in a project. A project network diagram is the output of the planning stage of a project, which involves defining the project requirements, scope, schedule, cost, quality, resources, and risk. A project network diagram helps to determine the critical path, the float, and the milestones of the project, and to monitor and control the project performance13. Project integration management is a process that coordinates and integrates all the aspects of a project. It involves developing, executing, and controlling the project management plan, which includes the subsidiary plans for scope, schedule, cost, quality, resources, communications, risk, procurement, and stakeholder management. Project integration management is performed throughout the project lifecycle, and helps to ensure that the project deliverables meet the project objectives and the stakeholder expectations14. Project boundaries are the limits or edges of the project scope that define what is and what is not included in the project. Project boundaries are determined by the project requirements, assumptions, constraints, and exclusions, and help to clarify the project scope and avoid scope creep. Project boundaries are established during the planning stage of a project, and are documented in the project scope statement1 . References:
