Analysis on nine knowledge fields of PMBOK

Gao maoyuan's nine knowledge fields:

I. Scope Management

The most important concern is the requirement. It is necessary to reach an agreement with the important stakeholders of the project to reach a commitment. The core is to create the WBS document for the project, detailed segmentation of the entire project. The most basic thing is to compile the sow of the project. At the same time, sow updates run through the whole process of the project.

Ii. Time Management

The most important thing is to estimate the activities included in the project based on the project's multi-dimensional splitting and the project's WBS. At the same time, we also need to take into account the debug time, which generally accounts for 2/3 of the entire development cycle. Time management focuses on workload estimation of project activities. The estimation methods adopted include bottom-up WBS-based estimation, analogy estimation, expert estimation, and function point estimation.

Iii. Cost Management

As the name suggests, cost management focuses on money calculation, while cost calculation is based on the detailed splitting WBS to estimate costs. The estimation method is consistent with the estimation method of time management. Here, an important concept is EVM (Earned Value Management). PV considers the budget cost, while AC considers the actual cost, ev considers the progress. Sometimes, we also say that the EVM puts the range, time, and workload together and is uniform. Ev (Earned Value) is used to measure the workload.

Iv. Quality Management

Quality management focuses on seven figures:

1. Checklist Diagram

2. The Fishbone Diagram also becomes a causal relationship

3. Histogram

4. Multi-Party Diagram

5. Six Sigma chart

6. statistical process control diagram

7. Time trend chart

V. Human Resource Management

First, it must be clear that people are resources, also known as "things", and resources measured by money.

Several well-known theories

1. Maslow's hierarchy of needs theory

2. haizberger's incentive theory

3. x, y, and z Theories

4. Leadership theory, which is also called the Ohio Theory

5. The leader's life cycle theory, also known as the contingency theory

The purpose of team building is to increase productivity. division of labor is more important than morale, and a responsibility allocation matrix needs to be created.

For the handling of conflicts in team building, major conflicts are ignored.

6. Communication Management

It should be noted that there are problems with both Chinese translation and our understanding, and communication management should be more appropriate.

There are two ways of communication here. One is face-to-face communication. The key point is that it is not the right person. At this time, we will always stand in the opposite party's perspective and listen from our own perspective, at the same time, you must take the initiative to understand the intention of the other party and repeat it to let the other party confirm whether the information you understand is consistent.

The second is the communication of documents, which transfers the project progress report and Project Performance Report to the people who need it most, so as to effectively transmit information. We generally think that in communication management, document communication is very important. To a certain extent, it can determine the success or failure of the project.

Communication Management can also be understood as relationship management to a certain extent. It is an important indicator to determine the quality of a project manager.

VII. Risk management

We are used to saying that we have nothing to do with finding things. We usually focus on common risks, and we should not identify too many risks. It should be around 10, take effective measures to cope with risks. If the risk of a small profile occurs, the premise of the entire risk will be problematic. You need to carefully and systematically analyze it.

VIII. Procurement Management

It can be summarized into three words, when Party. Clarify the workflow of bidding.

IX. Overall Management

Is the management in management, is the integration of the other eight knowledge areas, forming a project plan.
