To control the schedule, a project manager is reanalyzing the project to predict project duration. She does this by analyzing the sequence of activities with the LEAST amount of scheduling flexibility. What technique is she using ?
There are only two choices related to scheduling; critical path method and precedence diagramming. Precedence diagramming, however, is a diagramming, technique that deals with the relationship between activities, not schedule flexibility. The project manager is analyzing the critical path.
While reviewing one of the activities of team member, you found out that the activity has an early start of days 5, an early finish of day 12, a late start of day 15, and a late finish of 22 day. The team member tells you that he needs an additional four days to complete the activity due to various reasons he can think of. Which one of the following statements is TRUE ?
The float/buffer of this activity is Late Finish - Early Finish = 10 days. The activity is not critical path because it has a float/buffer of 10 days. Even if the team member takes 4 additional days to complete the activity, it probably will have no impact on the project schedule or on the successor activity
if the optimistic estimate for an activity is 12 days, and the pessimistic estimate is 18 days, what is the standard deviation of this activity ?
The standard deviation is computed by [P - O]/6. Therefore , the answer is [18-12]/6 = 1
A project manager wants to determine how his project is doing the end of sixth month. The actual total expense of the project is $720,000. The planned budget for this length of the time was $600,000. He finds that :
The Actual Cost (AC) for 6 months of work = $720,000 while the Planned Value (PV) for the same period is $600,000. There is no Earned Value (EV) information given. In order to find out Schedule (SV) and cost variance (CV), EV is required. Hence, there is not enough information to determine how the project is doing
A project's approved budget is $250,000 and planned budget to date is $150,000. What will be the Schedule Variance when Schedule Performer Index is 0.8 ?
Schedule Performance Index = Earned value / Planned Value
EV = 0.8 x 150,000 = $120,000
Schedule Variance = EV - PV = $120,000 - $ 150,000 = -$30,000
Which one of the following takes progressive elaboration approach and plans the work in the near term in detail and future work in a higher level ?
The rolling wave planning takes progressive elaboration approach and plans the work in the near term in detail and future work in a higher level. During the early strategic planning phase, work packages may be decomposed into less-defined milestones level since all details are not available and later they are decomposed into detail activities.
This kind of planning is usually used in it and resource project but it is very unlikely in construction projects where any unknown are extremely expensive and destructive
While working with your team members on activity sequencing, a team member identifies that a series of activity sequencing method may be utilized in this situation ?
The Precedence diagramming method creates a schematic display of the sequential and logical relationship of the project activities. Usually, it shows dependencies and the order in which activities in a project must be performed.
Which one of the following estimating techniques uses mathematical models based on historical records from other projects and can produce higher levels of accuracy ?
This estimate uses mathematical models based on historical records from other projects. It utilizes the statistical relationships that exist between a series of historical data a particular delineated list of other variables.
Measure such as time per line of code, time per installation, and time per linear meter are considered in this type of estimate.
You are overseeing a data center project, the team members have finished creating WBS and WBS dictionary also completed activity sequencing and submitted their activity duration estimates to you. Recently, you developed the project schedule. What should you be focusing on next ?
The Control Schedule process is the next process after the Develop Schedule process but all the activities of the Develop Schedule process are not completed yet once the schedule is developed, it should be compressed, finalized, and approved by stakeholders. Then you should start controlling the schedule
Which of the following is FALSE about analogous estimating ?
In a bottom-up approach, one estimate per activity is received from the team member.
