After the project started, Xiao Wang divided the team into development implementation group and quality control group, and formulated scope management plan, schedule management plan and quality management plan.
In order to maintain good communication with customers and ensure the completion of the project as soon as possible, Xiao Wang led the development team to Party A's site for development. After several meetings and communication with customers, Bao Xiao formed a demand document based on his own experience. Then arrange the developers to work according to this document first, and then improve the specific requirements details later.
During the development process, customers constantly put forward new requirements, and Xiao Wang arranged for developers to modify the requirements documents at the same time. The development work was repeated many times. 2065438+February 2009, the development work only completed 50% of the plan. At this time, Xiao Wang arranged for the project quality engineer to enter the site and found many quality problems. Xiao Wang immediately organized the developers to work overtime to modify. Because several colleagues in the project team also undertake other projects, the working hours cannot be guaranteed, and the project implementation progress is seriously lagging behind.
Xiao Wang reported the progress of the project to Li Zonghui, who was dissatisfied with the current situation of the project, and dispatched two employees with many years of experience in project implementation to the site for support. After hard work, the project was finally postponed for four months. Xiao Wang believes that the project delay has something to do with the customer, and there is a dispute with the customer, which makes the project unacceptable so far.
(1) adopt the top-down method to make the project management plan. Make the overall project management plan first, and then decompose other sub-plans such as quality and progress.
(2) Risk identification is not required at the start-up stage of the project.
(3) The basis of total change control includes project management plan, work performance report, change request and organizational process assets. ()
(4) The closing results of the project include the handover of final products, services or results. ()
(5) The project management plan is gradually refined as the project progresses. ()
(6) In the process of project implementation, other process management such as scope, schedule and cost should be implemented first, and then the overall management of the project should summarize the implementation of other knowledge fields, and then carry out overall coordinated management.
A company won the bid for a software development project, and the project manager estimated the duration and budget cost of each task in the development process according to previous experience, as shown in the following table.
A company undertook a software development project, and the customer asked for delivery in 4 months. In view of the fact that the system has few functions and is relatively independent, the project management office of the company thinks that the project can be used as a pilot project of agile method after evaluation. The company transferred idlers from various R&D groups to form a project team, and appointed Xiao Zhang as the project manager.
When the project team was first established, everyone was full of confidence in agility and project objectives, but not long after the work began, the project manager Xiao Zhang and the project member Lao Wang had differences on the technical route. After several rounds of discussion, both sides insisted on their own opinions. Xiao Zhang thought that this seriously damaged his authority as a project manager, so he tried to transfer Lao Wang from the project team and let the project team adopt the technical route he proposed.
For a month, the team has been working hard, but still failed to complete the task of the first iteration cycle as planned. As for the reasons for the delay, the team members accused the project manager of not making a good plan, unreasonable assignment of tasks, unclear assessment rules for individuals, and unsmooth communication at the workstation: the project manager accused the project members of lack of ability, bad work habits and poor understanding of tasks. The team encountered unexpected difficulties, which may lead to delays in delivery.

Draw a network diagram according to the logical relationship between activities given in the diagram.
1) What is the shortest duration of the project?
2) What is the critical path?
3) Activity E's (total) time difference and free time difference?
Solve the problem:
1) The critical path determines the shortest project duration. This is the longest one.
3+6+4+5= 18 days
A, E, F, 3+8+3= 14 days
3+6+4+3= 16 days
Therefore, the shortest construction period is 18 days.
Critical path A B C D
3) We start from 0, so A is 0 at the earliest.
The activity time difference on the critical path is 0, so the earliest start, the earliest end, the latest start and the latest end of ABCD,
You can be sure. The earliest start and end of e can be determined.
Take the maximum forward push: forward push refers to the path convergence point of F, and forward push is the earliest start of pushing F, taking 13 in ce.
1 1 The maximum is 13, so the earliest start of f is 13. This sentence is called "Push forward to maximize"
Then, we know that the construction period is 18 days, so F can be completed in 18 days at the latest, and the latest end time of F is?
18 days, and f starts at 15 days at the latest.
Reverse minimum: looking back at the latest time, for the branch point of path C, take the minimum values of 13 and 15 in DF.
So the latest ending of c is 13. Of course, C is also on the critical path, and we can also judge the previous critical path.
It has been confirmed.
3) the total time difference and free time difference of e.
Total time difference e = 15- 1 1, or 7-3=4 days.
Then calculate the free time difference of e: the concept of free time difference: on the premise of not affecting the earliest start time of follow-up activities,
The activity can be postponed until the start time. The earliest start time of F is 13, so E will end in 13 days, 138+0 1 = 2 days.
Free time difference e =2 days.
Overview of critical path method;
PERT is a three-point estimate. The critical path method is single-point estimation, and the most possible value is used to estimate the activity time. Don't think about anything
Resource constraints, find the longest path to determine the shortest duration, because it does not consider resource constraints, it is a theoretical value.
1) has at least one critical path; The more critical the path, the greater the risk;
2) The activity time difference on the critical path is equal to 0 in most cases, but it can also be positive or negative;
3) If the time difference of the key activities is less than 0, it means that the key activities have been postponed, or the management requires that they be completed in advance, which
You need to compress the progress.
