The first thing to say is that project management is more than just a kind of professional knowledge, let one-and-a-half-way into the river and lake era has passed. The needs of project managers in today’s knowledge economy and WTO era will become stronger and stronger, will not only multinational enterprises need it, any government, enterprises and different industries are indispensable, but also the “amulet” of personal career.
Now this era is different, guerrilla style of play is no longer suitable for this era, this era more need professional regular army play, with project management knowledge is AL MUST rather than PLUS. We do not have to take into account the PMP certificate spotodumps.com gold content problem, learn knowledge, in the work practice, show practical ability, is a PM should do.
To put it bluntly, let’s talk about the PMP exam. PMBOK this book is a project management professional Bible, many universities and institutions are learning from this book to build their own project management courses. The author suggests that it is absolutely beneficial to read more than a few times, for the number of questions is also a lot of people are asking. At least three times during the training phase is necessary. Then listen carefully in class and interact actively to understand the difficult knowledge points in PMBOK. Can not rush in a few short lessons to eat this book through, in fact, it is also very difficult, after all, the project management profession is a very practical, but also a sustainable development of the subject, first pass the PMP exam is the most important.
Regarding the fifth space for PMBOK explanation, other training institutions are in accordance with the knowledge of project management areas to explain, only Zhu teacher is in accordance with the project management process group to explain. In practice, in the application of knowledge, the project manager will not manage the project according to the knowledge area of project management, but to manage the project integrated. Therefore, Zhu teacher’s explanation, can help you to establish the framework of project management knowledge system as soon as possible, systematic learning PMBOK, but also for students after the PMP exam work practice, lay a good foundation. PMI was established in 1969. In 1976, PMI proposed the idea of establishing project management standards. After ten years of hard work, PMI launched the “Project Management Knowledge System” in 1987, referred to as PMBOK. PMBOK has become a globally recognized project management industry standard. It is distributed globally in 11 languages and is known as the “Bible” in the field of project management. Most project management research institutions regard it as the basis of the project management qualification certification exam and always maintain its authoritative status. The International Organization for Standardization uses PMBOK as the framework to formulate the ISO1006 standard.In 1999, the PMP certification exam was the first to obtain ISO9001 international quality certification among all certification exams, thus becoming one of the most authoritative certification exams in the world.According to the “China PMP Development Status Report” issued by the State Administration of Foreign Experts Affairs in 2014, the PMP certification exams are currently in 192 countries around the world, with a total of 550,000 members worldwide. In 2014, the number of PMP certifications increased by 15-20%.The PMI certification system provides a structured approach to career development, which not only contributes to the improvement of project management knowledge and skills, but also contributes to the development of personal careers.
In the last issue, we talked about a difficult point in the PMP exam – the tight-forward relationship drawing method, that is to say, when we draw the schedule, we can’t help but consider the logical relationship between the activities, and often draw the network diagram first. In the last issue, we only talked about one of the network diagram methods, that is, PDM (interested students can go out and turn left to see the content of the previous issue of the public account – the tight relationship drawing method – PDM). Today we’re going to talk about ADM.
Arrow Diagram Method (ADM), also known as The Vector Diagram Method or The Activity-On-Arrow (AOA) is a method for the specific application of the plan review method in quality management, so that the planning of quality management has a time schedule content. It is conducive to proceeding from the overall situation, making overall arrangements, grasping key lines, concentrating forces, and completing plans on time and ahead of schedule. It is the application of network diagrams in quality management.
The arrow line diagram method uses the arrow line to represent the activity, the activities are connected by nodes (called “events”), can only represent the end-beginning relationship, each activity must be described by a unique front event and a unique close event; the number of the front event must be less than the number of the close event; each event must have a unique event number. For example, the following graphic:
From the above description, the main differences between ADM and PDM are as follows:
PDM is a graphic in which the box is active and the arrow line is the logical relationship; the arrow line of the ADM represents both the activity and the logical relationship;
Since the arrow line has only one direction, the logical relationship in the graph is only the FS (finish to start) relationship;
Due to the need for four logical relationships in the network diagram (four kinds of FS/SS/FF/SF, etc.), the dotted line in the diagram can represent the virtual activity (for example, in the above figure, in order to start the C activity, you need to complete the B activity and the D activity first).
In summary, the basic logic of ADM and PDM is the same except for the representation, so any topic can be drawn using either PDM or ADM. It’s just that the PDM way of thinking is simpler, so PDM is more popular. However, in PMP exams, ADM questions still appear frequently. For example, the following question:
Example 1.
The project sponsor asks the project manager to reduce the total duration of the project by one day, what should the project manager do next?
Rush to activity I-J for a day
On the activity G-K rush work day
For activities A – B rush a day
On the activity H-J rush work day
To solve this problem, it is not enough to read ADM, but also to know another knowledge point – the critical path method. That is to say, the current network diagram has multiple paths, and only by finding the critical path can we start to determine which activities are most appropriate to shorten. When doing this kind of problem, you must do more hands and do the math.
Analysis: Answer A. This question is the Alignment Activity Order Tool— The Close Relationship Drawing Method (ADM), the Scheduling Tool— the Critical Path Method. The title shows an ADM arrow line chart, and the duration of the project is determined by the critical path. There are several paths in the figure:
Path number
Path
Duration
1
A-B-E-G-K
10
2
A-C-F-G-K
11
3
A-C-F-I-J-K
12
4
A-D-F-I-J-K
12
5
A-D-H-J-K
8
Explain that the 3rd and 4th paths are the critical path, if you want to shorten the duration of the day, you have to start from the 3rd and 4th paths, the two paths coincide: F-I, I-J, J-K, only the A option in the title meets.
Then let’s look at the question again:
Example 2.
According to the project network diagram, the project manager finds which of the following is the highest progress risk point in the project?
In fact, this topic is relatively simple. The key word is “the highest progress risk point”, so what is the highest progress risk point? It depends on which point has the greatest chance of causing a delay in progress.
Parsing: Answer C. This question is a network diagram of the project progress of 6.3.3.1. This question tests the content of the arrow line diagram, the question requires to point out the highest risk point, then you need to see which point is most likely to cause progress delay, that is to say, which point is the most passed by each path. It has been judged that 1, 6, and 8 are the most passed points, but the two points of 1 and 8 represent the beginning and completion respectively, so only the point 6 meets.
In the PMP exam, there are many similar drawing questions, and the tight relationship drawing method is only part of it, and this kind of problem requires candidates to practice more, practice makes perfect, and correctly do all the problems correctly at once.click\here
