The overall project management knowledge field includes the various processes and activities required to identify, determine, combine, unify and coordinate different processes and project management activities within each project management process group. It is an overall and comprehensive management.

1. Project Charter Concept. The project charter is the document that formally approves the project. Because the project charter authorizes the project manager to use the organization's resources in project activities, the project manager should be delegated at any time before planning begins, preferably when the project charter is developed. The approval of the project charter marks the official launch of the project. In a project; the project manager should be identified and appointed as early as possible. Since the project charter will authorize the project manager to use organizational resources in project activities, the project manager should be involved in developing the project charter. Projects are approved by people outside the project, such as the sponsor, the project management office, or the portfolio steering committee. When the project charter is signed by the initiator, the project is approved.

2. Contents of the project charter. The project charter should contain the following content (directly included or referenced from other documents):

3. Statement of work. Project Statement of Work: A statement of work is a written description of the products or services to be provided by the project. For internal projects, the project sponsor or sponsor provides a statement of work based on business needs, product or service requirements. For external projects, the statement of work is part of the customer's bidding documents, such as an invitation for proposals, a request for information, an invitation to bid, or part of the contract. The statement of work specifies one of the following matters:

4. Business environment factors include but are not limited to the following matters.

5. Organizational process assets: Organizational process assets reflect the organization's lessons learned and learnings from previous projects, such as completion schedules, risk data, and realized value data. Can be summarized into two categories: ① Organize the process and procedures for carrying out work; ②Organize the overall information storage and retrieval knowledge base.

6. Financial considerations have always been an important consideration in the project selection process. The three main project financial value evaluation methods include net present value analysis, investment income and investment recovery rate analysis.

7. The project kickoff meeting is the beginning of a project, and is generally organized and held by the project manager. The main purpose of convening a project kickoff meeting is to make the main stakeholders of the project clear about the project's goals, scope, needs, background, and their respective responsibilities and authorities.

8. Project goals include achievement goals and binding goals. There are often contradictions or even conflicts between achievement goals and binding goals. Has the following characteristics: ①The goals of the project have different priorities; ②The project goals are hierarchical.

9. Facilitation techniques can be used to guide the development of the project charter. Brainstorming, conflict management, problem solving, and meeting management are all key techniques that facilitators can use to help teams and individuals complete project activities.

1. A project management plan generally includes project scope management plan, schedule management plan, cost management plan, quality management plan, process improvement plan, staffing management plan, communication management plan, risk management plan, procurement management plan, etc. The project management plan can be as detailed as possible.

2. The project management plan records all results of each planning sub-process of the planning process group, including:

3. When formulating the project management plan for the first time, since all aspects of the information are not very clear, the project manager only needs to grasp the main management ideas of the project from a macro perspective, and remember not to idealize and expect the project management plan to be in place in one step.

4. A project management information system consists of tools and techniques used to summarize, synthesize, and disseminate the output of project management procedures. A project management information system mainly consists of two parts - the planning system and the control system.

5. The configuration management system and change control system are subsystems of the project management information system.

1. Guiding and managing the project execution process requires the project manager and project team to take a variety of actions to implement the project management plan and complete the work specified in the project scope statement.

2. Expert judgment: Invite some experts to come over and provide some suggestions and opinions on project construction.

3. Work performance data are the raw observations and measurements collected from each activity being performed during the execution of the project work. Data refers to the lowest level details from which other processes will extract project information. Data is collected during work execution and passed to each control process for further analysis. Job performance data includes, but is not limited to, the following items.

4. Updates to the project management plan.

5. Project files updated.

1. Monitoring the project work process is to monitor and control the various processes required to initiate, plan, execute and close the project. Take corrective or preventive actions to control project implementation effects. Monitoring is an aspect of project management that occurs throughout the project. Monitoring involves collecting, measuring, disseminating performance information, and evaluating measurement results and trends to implement process improvements. Continuous monitoring allows the project management team to gain insight into the status of the project and identify any areas that may require special attention.

2. Progress forecast: A schedule forecast, an estimate of how long it will take to complete, is calculated based on a comparison of actual progress with the schedule baseline, usually expressed as schedule deviation and schedule performance index.

3. Cost forecast: The estimate to completion, calculated based on comparison of actual progress to the cost baseline, is usually expressed as cost variance and cost performance index.

4. Confirmed changes: Approved changes are the result of implementing an overall change control process. Their implementation needs to be confirmed to ensure that they are implemented correctly. Confirmed changes use data to demonstrate that the changes have been correctly implemented.

5. Analytical techniques: In project management, analytical techniques are used to predict potential consequences based on possible changes in project or environmental variables and their relationships with other variables. For example, analysis techniques that can be used on projects include: regression analysis; grouping methods; causal analysis; root cause analysis; predictive methods (such as time series, scenario building, simulation, etc.); failure mode and effects analysis; fault tree analysis; reserve analysis; Trend analysis; earned value management; variance analysis.

6. A job performance report is a physical or electronic project document that compiles job performance information for the purpose of making decisions, taking action, or raising concerns.

1. The overall change control process runs throughout the project. Because projects rarely follow the project management plan exactly, change control is essential.

2. Several configuration management activities in the overall change control process are as follows.

3. The overall change control process includes a change control board responsible for approving or rejecting change requests.

4. The change log is used to record changes that occur during the project. These changes and their impact on project time, cost, and risk should be communicated to relevant stakeholders. Denied change requests should also be recorded in the change log.

1. Ending a project or phase is the process of completing all activities of all project management process groups to formally end the project or phase. The main function of this process is to summarize experiences and lessons, formally end the project work, and release organizational resources for new work.

2. Acceptance deliverables may include approved product specifications, delivery receipts, and work performance documentation. Phased projects or canceled projects may include incomplete or intermediate deliverables.
