To control the schedule a project manager is analyzing the sequence of activities with the least amount of scheduling flexibility to predict the project duration. What technique is she using?
The data of the old system is migrated to the new system. The optimistic estimate is 4 days. It is most likely to estimate 7 days. Pessimistic estimate is 16 days and the beta distribution is adopted to calculate the expected value and standard deviation. Which of the following is true?
One project team member reported that because the technical staff who had been cooperating with her had left they needed to re-recruit the replacement one so the original start time of the activity had to be delayed by 2 weeks. Because the project is very important to the company this unexpected situation has caused the management to be very nervous. As the project manager,when you report the progress of the project you insist that the project can be completed on schedule without worrying about it. Why can you say that?
A:活动处于关键路径上,你会重点关注;
The activity is on the critical path and you will focus on it;
B:活动处于非关键路径上,且总浮动时间大于2周;
The activity is on the non-critical path and the total floating time is greater than 2 weeks;
C:活动处于非关键路径上,无论如何不会影响总工期;
The activity is on a non-critical path regardless of how the total project duration is not affected;
D:活动处于关键路径上,团队可以加班赶回来。
The activity is on the critical path and the team can work overtime.
The project manager does not allow team members to increase any buffer to the duration estimates of activities. But he himself adds an extra by five weeks to the project schedule which is reported to the sponsor. What do you think about?
A:项目经理太自私,欺下瞒上;
The project manager is so selfish that he is playing politics;
B:项目经理这么做没错,他争取的是管理储备;
The project manager is right he is fighting for management reserve;
C:项目经理这么做没错,他采用的是关键路径法;
The project manager is right he used the critical path method;
D:项目经理这么做没错,他采用的是关键链法。
The project manager is right he used the critical chain method.
The project resources had been overloaded but the project manager could not get more resources and there was still a certain amount of surplus in the project duration. What is the best thing for the project manager to do?
A:将非关键路径改为关键路径;
Change the non-critical path to the critical path;
The project manager found that some activities on the critical path had been delayed. Functional departments had no more resources available and because of the logical constraints between activities on the critical path fast-tracking method could not be used. What should the project manager do if the project must be delivered on time?
The start time of activity A and B is not limited and the duration is 2 weeks and 3 weeks respectively. "A" and "B" finish to start “C” "C" takes three weeks; Activity D requires 4 weeks but must begin after B is completed; Both C and D finished the project can be completed. Activity A is three weeks behind schedule because the resources are not available. This will result in:
A:项目总工期延误3周;
The project duration is delayed by 3 weeks;
B:项目总工期延误2周;
The project duration is delayed by 2 weeks;
C:项目总工期延误1周;
The project duration is delayed by 1 week;
D:项目总工期不变,但C活动浮动时间减少1周。
The project duration is unchanged but the floating time of activity C decreases by 1 week.
At the project status report the project manager's CPM graph shows that the total floating time of two activities is negative and which one of the following conclusions can you draw from the analysis?
A:这两项活动都在关键路径上;
Both activities are on the critical path;
B:两项活动的最早开始时间都早于最晚开始时间;
The early start time of the two activities is earlier than the late finish time;
C:两项活动的最晚结束时间都早于最晚开始时间;
The late finish time of the two activities is earlier than the late start time;
D:因为活动有负浮动时间,所以项目进度比计划超前了。
Because of negative floating time the project progress is ahead of schedule.
