The schedule performance index shows how well the project is performing on schedule. It is found by dividing the earned value by the planned value. Schedule variance (SV) is a measure of schedule performance on a project. The variance notifies that the schedule is ahead or behind what was planned for this period in time. The schedule variance is calculated based on the following formula: SV = Earned Value (EV) - Planned Value (PV) If the resulting schedule is negative, it indicates that the project is behind schedule. A value greater than 0 shows that the project is ahead of the planned schedule. A value of 0 indicates that the project is right on target.

Answer option D is incorrect. EV-AC is the project's cost variance.

Answer option B is incorrect. EV/AC is the project's cost performance index.

Answer option A is incorrect. EV-PV is the project's schedule variance.

Sequence Activities is one of the twenty processes of the Planning Process group. It is the process of identifying and documenting relationships among the project activities. Inputs Following are the inputs to this activity:

Activity list

Activity attributes

Milestone list

Project scope statement

Organizational process assets

Outputs Following are the outputs of the sequence activities process:

Project schedule network diagrams

Project document updates

The variance at completion can be found by subtracting the estimate at completion from the budget at completion. In this instance, it is:

Variance at completion = EAC - BAC

= $1,258,456 - $1,312,500.

= -$54,044

Answer option C is incorrect. You can calculate the variance at completion.

Answer option A is incorrect. This is the cost variance for the project.

Answer option B is incorrect. This is the schedule variance for the project.

The code of accounts is a hierarchical numbering system that uniquely identifies each deliverable of the WBS and segments the WBS by levels of numbering.

Answer option C is incorrect. Component numbering is not a valid term for project management.

Answer option B is incorrect. A chart of accounts is a financial tracking and assignment tool for common deliverables and activities an organization performs for its customers.

Answer option D is incorrect. Activity linkage sequencing is not a valid project management term.

The Monte Carlo simulation tool allows a project manager to explore "what-if" analysis for the project schedule and possible combinations of events in the project. Monte Carlo simulation is a process for iteratively evaluating a deterministic form using sets of random numbers as inputs. This method is repeatedly used when the model is complex, nonlinear, or involves more than just a couple of vague parameters. Monte Carlo simulation is named after the city in Monaco, where the major attractions are casinos that have games of chance. Gambling games, such as roulette, dice, and slot machines, exhibit random behavior. This technique works particularly well when the process is one where the underlying probabilities are known but the results are more difficult to determine. It is a process that generates hundreds or thousands of probable performance outcomes based on probability distribution for cost and schedule on individual tasks. The outcomes are then used to generate a probability distribution for the project as a whole.

Answer option D is incorrect. GERT is the Graphical Evaluation Review Technique and is a visual mapping of the project work including branches and loop backs within the project.

Answer option A is incorrect. PERT is the Program Evaluation and Review Technique and is used for project scheduling and time estimating.

Answer option C is incorrect. PMIS is a project management information system, such as Microsoft Project, and often includes what-if analysis tools, but it's not the best answer for this question.

Lag time is positive time that requires the successor activity to wait for a defined amount of time, such as three days, before it can begin. Lag time does not change the task relationship, but requires a "waiting time" before the starting of the activity can begin. A lag time is a delay between the predecessor and the successor tasks. Sometimes it may be needed to schedule a delay between the predecessor and the successor tasks. For example, if two coats of paint are required to paint a car, then the final coat should be applied only when the first coat dries. This delay is known as the lag time. The lag time is entered as a positive value. The lag time can be entered as a duration or as a percentage of the predecessor's task duration. It is entered on the Predecessor tab in the Task Information dialog box.

Answer option D is incorrect. Float is a natural event that is discovered through the forward pass when using the critical path method. Float cannot be arbitrarily added as lag.

Answer option C is incorrect. Lead time actually brings activities closer together and causes them, in some cases, to overlap.

Answer option B is incorrect. Management reserve is a pool of time allotted for unscheduled changes and events that affect the project duration.

The earliest Activity G can start is Day 17. This is because activities A, D, C, and F must all be completed before Activity G can start.

Answer option A is incorrect. Day 13 does not account for Activity F since Activity F is also a predecessor to Activity G.

Answer option C is incorrect. Day 22 is the earliest Activity G can finish.

Answer option B is incorrect. Day 7 is not a valid answer.

Crashing adds project resources and usually increases costs - though it may also increase some project risks. Crashing is a schedule compression technique to obtain the greatest amount of compression for the least incremental cost. Crashing works for activities where additional resources will shorten the duration. Approving overtime, bringing in additional resources, paying to expedite delivery to activities on the critical path are examples of crashing.

Answer option D is incorrect. Crashing does not always increase project risks.

Answer option C is incorrect. Crashing does not restrict resource utilization - that is resource leveling.

Answer option B is incorrect. This is not a valid definition or description to crashing the project.

Of all six processes, the control schedule process will take the majority of the time in the project time management knowledge area. Control schedule process is a method of monitoring the status of the project to update project progress and deal with the changes to the schedule baseline. It is concerned with: Determining the current status of the project Influencing the factors that create schedule changes Determining that the project schedule has changed Managing the actual changes as they occur Control schedule is a component of the Perform Integration Change Control process.

Answer options B, A, and D are incorrect. These processes will not take the longest to complete.

Cost performance index (CPI) is used to calculate performance efficiencies. It is used in trend analysis to predict future performance. CPI is the ratio of earned value to actual cost. The CPI is calculated based on the following formula: CPI = Earned Value (EV) / Actual Cost (AC) If the CPI value is greater than 1, it indicates better than expected performance, whereas if the value is less than 1, it shows poor performance. The CPI value of 1 indicates that the project is right on target. In this instances it is $270,000 divided by $335,000 for a CPI of .81.

Answer option B is incorrect. .67 is actually the schedule performance index.

Answer option D is incorrect. -$65,000 is the cost variance for the project.

Answer option A is incorrect. -$135,000 is the schedule variance of the project.
