5、 Project management

1、 project management

Examination site ： Concept

Four factors of project success ： Range 、 speed of progress 、 cost 、 quality

Four basic stages ： Conceptual stage 、 The development phase 、 Implementation phase and completion phase .

Scope Management ： Unclear definition of project scope is often the primary cause of project failure , Project scope management is the project plan 、 The basis of control , Project scope management determines the specific tasks of the project , Contribute to clear division of responsibilities and assignment of tasks . Input to the scope definition includes the project charter 、 Project scope management plan 、 Organizational process assets 、 Approved change request

Project plan ： Is to coordinate the preparation of all project plans 、 Documents guiding project implementation and control , The key part is the project introduction 、 Project description 、 Project management and technical process 、 And work progress information and budget information

Project master plan ： Scope plan 、 Scope of work definition 、 Activity definition 、 Resource requirements 、 Resource Planning 、 Activity sequencing 、 Cost estimates 、 Schedule and cost plan

Project support plan ： Quality plan 、 Communication plan 、 Human resources plan 、 Risk plan 、 Purchase plan

Schedule management ：

Configuration Management ： Lies in the use of configuration identification 、 Configuration control 、 Configuration status and configuration audit , Establish and maintain the integrity of work products .

Configuration management work results ： The requirements document 、 Design document 、 Source code and test cases .

Documents generated by project management and institutional support processes ： Work plan 、 Project quality report and project tracking report

Cost management ： Estimated cost 、 Specify budget 、 Control the cost

2、PERT chart

Examination site ： Draw... According to the topic information PERT chart , Calculate critical path , Total construction period , Relaxation time .

Draw... According to the topic information PERT chart

According to the dependency , Draw a precursor map , Complete each task node in the precursor diagram according to the following figure . The earliest time Forward thrust Calculation , Latest time Backstepping Calculation .

The first time	Time limit	End at the earliest
Mission
At the latest	Relaxation time	At the latest

Serial tasks The longest time Our route is the key route , The earliest and latest time of the critical route is the same , The sum of critical path duration is the total duration .

Slack time in parallel tasks （ Non critical route ）, Relaxation time = At the latest - The first time
