Causal Analysis Techniques in Project Management 5

To use this method, we must first distinguish between cause and effect; Secondly, we should pay attention to the causal correspondence, any result is caused by a certain cause, and a certain cause produces a certain result. Cause and effect are often one-to-one correspondence and cannot be confused; Finally, it is necessary to follow the cause and effect, grasp the cause and effect, and use different ways of thinking to conduct causal analysis from different directions, which is also conducive to the development of multi-directional thinking.

According to the causal relationship between things, know the cause and measure the effect or reverse the effect to find the cause. Causal analysis is the basis of the entire analysis.

Causal analysis (technique) is applied in project management, which is a method that takes the result as the characteristic and the cause as the factor, and gradually studies and discusses the current problems of the project. The deliverable of causal analysis is a causal analysis diagram.

Once the cause-and-effect diagram has been identified, the project team should interpret it to identify the most basic cause through statistical analysis, testing, collecting more data about the problem, or communicating with the client. Once the underlying cause has been identified, the project team can begin to develop a solution and make improvements. The characteristics of the problem are always affected by some factors, and we find out these factors through brainstorming, and together with the characteristic values, organize them into a hierarchical and well-organized pattern according to interrelatedness, and mark the important factors in the graph.

Because its shape resembles a fishbone, it is also called a fishbone diagram (hereinafter referred to as a fishbone diagram), and it is an analytical method that looks at the essence through phenomena. At the same time, the fishbone diagram is also used in production to visually represent the process of the production workshop.

Brain Storming (BS): A meeting method that uses brainstorming and group wisdom to identify all the causes or components of a problem from a variety of different perspectives. BS has four principles:

Criticism, free-spiritedness, more is better, and free-riding are strictly prohibited. Basic structure of a fishbone diagram.

a. Organize the problem-type fishbone diagram (there is no causal relationship between each element and the characteristic value, but the structural composition relationship, and the problem is structured and organized).

b. Cause-type fishbone diagram (the fish head is on the right, and the characteristic value is usually "why......)."to write)

c. Countermeasure fishbone diagram (the fish head is on the left, and the characteristic value is usually "how to improve and improve......"to write)

Binary is , if you want to calculate by hand, for example, the algorithm that becomes the base is one, =, and the remainder;

2. = , remainder ;

Three, =, remainder ;

4. = , remainder ;

5. = , remainder ;

6. =, remainder ; So the binary of is ; The order of the remainders from bottom to top is his binary number.

1. The tools and techniques for qualitative analysis in project risk management include: the tools and techniques for qualitative risk analysis mainly include risk probability and impact assessment, probability impact matrix, risk qualitative analysis tool data and risk level, etc., which are all indicators that should be considered to determine risk priority. In some qualitative analyses, a combination of these can be considered.

2. Project risk management refers to a series of processes such as identification and analysis of project risks and even taking countermeasures, which includes maximizing the impact of the project risk management process generated by positive factors and minimizing the impact of negative factors.

Although there are many functions and techniques for risk management qualitative analysis, we have to take our functional responsibilities seriously. The treatment that can be solved is normal.

Program Review Techniques.

Refers to the use of network diagrams.

to express the progress of the various activities in the project and the interrelationships between them, and on this basis, network analysis and time estimation are carried out.

This method considers the duration of the project, as well as the length of time it takes to complete the project as a whole, to be random, following some probability distribution.

You can take advantage of the activity relationship and the weighted sum of the duration of the project, which is the mathematical expectation of the duration of the project.

Calculate project time.

Program Evaluation and Review Technique (PERT) and Critical Path Method (CPM) are an important part of network analysis, which is widely used in system analysis and project management, and the Program Evaluation and Critical Route Method was proposed and developed in the 50s of the 20th century. In 1956, DuPont proposed the Critical Route Method in order to coordinate the systematic planning of different business departments of the enterprise. In 1958, when the US Navy Armed Forces Department was developing the "Polaris" missile program, because the missile development system was too large and complicated, it designed a plan review method in order to find an effective management method.

Since PERT and CPM have the same target applications and many of the same terms, the two methods have been merged into one method, which is called Pert CPM in China and the scheduling method in China.

CPM and Pert are independently developed planning methods, but differ in their specific practices. CPM assumes that the time of each activity is deterministic, while the time of PERT's activity is based on probabilistic estimates; CPM considers not only the time of the activity, but also the cost of the activity and the trade-off between cost and time, while PERT considers less cost. The CPM uses a node-type network diagram, and the Pert uses an arrow-type network diagram. However, the basic principle on which the two are based is basically the same, that is, the logical relationship between the specific activities in a project plan is expressed in the form of a network, which is now collectively referred to as the network planning technology.
