How to conduct problem analysis and evaluation of the software system project being implemented

3. All project developers should not make the initiative to modify the program, there is no change control process, no management personnel or change controllers, and no CCB (change control committee).

This leads to increased development effort, unstable systems, uncertain requirements, and even difficult acceptance.

Change process: 1) Change application. Information such as the person who made the change, the date, and the content of the request for change should be recorded.

2) Change Assessment. Conduct a systematic analysis of the impact, severity, economic and technical feasibility of the change.

3) Change decisions. It is up to the person or organization with the appropriate authority to decide whether to implement the change.

4) Change implementation. The staff designated by the manager implements the change in a controlled state.

6) Communication archiving. Notify the people who may be affected of the changes and archive the changes in a summary and archive. If a proposed change is rejected at the time of decision-making, its initial record should also be kept.

Construction cost: Insufficient conditions, is it an information point? At present, the market price is about 50 yuan at one point, 5 is 250 yuan, 39 is 1950 yuan, 85 is 4250 yuan, and 355 is 17750 yuan.

You can use low-quality platforms to help implement the landing, such as Tianling, Tianzhong, Puyuan, these platforms can be realized

How can a project ensure that the actual execution of the project can be in line with the plan and control, and the eye-catching progress can be controlled?

1. Have a clear confirmation of the needs of the project: the start of a project must originate from a certain need or solve a certain problem. A clear analysis of the requirements and the precise positioning of the problem will allow the project to be in the right direction from the outset, avoiding wasted effort.

2. To formulate a reasonable project strategy: the first thing to formulate a project strategy is to start from the project team, and determine the project time, cost and scope according to the actual situation of the team, so as to ensure the quality of the project. The second is to manage the risk of the project, evaluate the risks that may occur in the implementation process, and plan to avoid, transfer or accept.

Avoid and use other means of execution to avoid risks, transfer and change elsewhere to reduce the possibility of this risk, acceptance is to evaluate the possibility of risk and accept the risk within the tolerance range.

3. In the process of implementation, once there is a problem, the impact of the problem on the entire project progress should be estimated, and the project plan should be adjusted in a timely manner according to the methods listed in the risk management to ensure the project quality, time and other unchangeable project requirements.

Hierarchical management and centralized responsibility. Each department is responsible for the daily supervision, inspection and assessment of the counterpart according to the functions performed by the department, the job responsibilities of the personnel and the work objectives and tasks undertaken. teemlink'The supervision and management work plan to distribution, to node control and feedback, and finally solve the performance, closed-loop execution, efficient solution supervision and auxiliary implementation tools.

The amount of 8 hours of work for 1 person is 1 person-day. 100 person-days equals 1 person doing 100 days or 100 people doing one day.

The starting point of design is demand. In the product life cycle, demand is a dynamic process, products can be divided into: introduction period, growth period, maturity period and decline period, products have different needs at different stages, and the types of needs are also different.

From the perspective of the object, the requirements are: basic needs, ease of use needs, and operability requirements;

From the perspective of product operation, the needs are: product operation needs, policy and legal needs;

From a system perspective, the requirements are: security requirements, performance requirements, maintainability and portability requirements;

The company has a mature demand collection, review and management mechanism. When judging the priority of requirements, the Kano model is used to determine whether it is a charismatic need, an expected need, a must-have need, an undifferentiated need, or a reverse need. For example, the folding screen mentioned earlier, taking photos on the front and back, and interaction between applications belong to the charm needs.

App splitting is an expected requirement. Folding reliability is a must-have.
