Intermediate soft test (system integration project management engineer) high frequency test site

According to the soft test intermediate in recent years （ System integration project management engineer ） From the analysis of the real exam questions , I found that there are some knowledge points that I often test .

Today, Xiaobian will share with you one of the high-frequency test sites ： Project schedule management , I hope it will help you prepare for the exam .

1、 Leading graph method （ Single code network diagram ）, It is also called the drawing method of tight relationship . There are four relationships ：FS、FF、SS、SF.

2、 Arrow diagram method （ Double code network diagram ）, Virtual activities represented by virtual arrows ： It doesn't consume time and resources , Just express dependencies , Make up the shortfall .

3、 Four dependencies between activities ∶
1） Mandatory dependency ∶ Law or contract .
2） Selective dependence ∶ It's logical / In order , First … Again ….
3） External dependency
4） Internal dependency

4、 Reserve analysis ：
1） Emergency reserve ：" It is known that - Unknown " risk .
2） Manage reserves ：" Unknown - Unknown " risk .

5、 Progress compression ：
1） Catch up schedule ： Increase resources , Carry out at the minimum cost ; May lead to risks 、 The increase in costs .
2） Fast tracking ： In parallel .

6、 Resource balance ： Realize resource optimization , Change the critical path ; Extension of time .
Asset smoothing ： Resource optimization may not be achieved , Will not change the critical path , The construction period will not be extended .

7、 Shorten the duration of activities ：
1） Rush to work , Invest more resources or work more hours , To shorten the duration of key activities ;
2） Fast tracking , Parallel construction , To shorten the length of the critical path ;
3） Use high-quality resources or more experienced personnel ;
4） Reduce the scope of activities or reduce the requirements of activities ;
5） Improved method or technology , To improve productivity ;
6） Strengthen quality management , Discover problems in time , Reduce rework , So as to shorten the construction period .
