Constructability analysis takes into account the location, logistics, resource availability analysis, the average price of general labor in the area, and labor productivity studies from previous similar projects in the area. Constructability analysis is a process that starts in the initial planning phases and persists all over the entire planning cycle and into the implementation phase of the project. Constructability analysis during the planning process examines the methods and cost of installed equipment and materials, technology, site conditions, resources, and related infrastructure. The benefit of constructability analysis is to reduce both the time and cost of a project. Constructability analysis is repeatedly performed throughout the life-cycle of a project in order to optimize cost, plan, and schedule while mitigating risk. It is a very important process that needs to be performed early in planning to allow alternatives to be considered and integrated into the design.

Answer option A is incorrect. This comes under the quality assurance phase.

The schedule performance index is found by dividing the earned value by the planned value. For Holly's project, it would be as follows:

SPI = EV/PV

= (0.85*9,850,400)/(0.95*9,850,400)

=8,372,840/9,357,880

=0.89

Schedule performance index (SPI) is the measure of schedule efficiency on a project. It is used in trend analysis to predict future performance. SPI is the ratio of earned value to planned value. The SPI is calculated based on the following formula:

SPI = Earned Value (EV) / Planned Value (PV)

If the SPI value is greater than 1, it indicates better than expected performance, whereas if the value is less than 1, it shows poor performance. The SPI value of 1 indicates that the project is right on target.

Answer option D is incorrect. Ten percent is not a valid calculation for this question.

Answer option B is incorrect. 0.98 is the cost performance index.

Answer option A is incorrect. 1.07 is the to-complete performance index based on the BAC.

Discrete effort is a term used to describe the work that can be measured and traced to the components in the work packages. It is the actual work to create the project deliverables. Discrete effort refers to the particular work effort that can be identified and traced as having a direct tie to the final completion of the project- related work breakdown structure components and the deliverables. It is necessary that all the efforts have a specific measurable end product or end result.

Answer options A, D, and C are incorrect. These are not valid definitions of discrete effort.

The critical path is the path in the project network diagram with the longest duration. In project management, a critical path is the sequence of project network activities which add up to the longest overall duration. This determines the shortest time possible to complete the project. Any delay of an activity on the critical path directly impacts the planned project completion date (i.e. there is no float on the critical path). This project actually has two critical paths. Path ACGIJ takes 23 days. Path ACGHJ also takes 23 days. When Activity I decreases by three days the critical will still take 23 days to complete as Path ACGHJ remains a critical path.

Answer option A is incorrect. The duration of the critical path did not increase.

Answer option D is incorrect. The duration of the path ACGIJ will decrease to 20 days but the critical path will remain at 23 days.

Answer option B is incorrect. The critical path did not reduce to 17 days.

The schedule baseline is a required component of the project management plan. Project management plan is a formal, agreed document that defines how the project is executed, monitored and controlled. It may be summary or detailed and may be composed of one or more subsidiary management plans and other planning documents. The objective of a project management plan is to define the approach to be used by the project team to deliver the intended project management scope of the project. The project manager creates the project management plan with the inputs from the project team and key stakeholders. The plan should be agreed and approved by at least the project team and its key stakeholders.

Answer option C is incorrect. The schedule baseline is not a project objective.

Answer option A is incorrect. The project calendar defines when the project will take place.

Answer option B is incorrect. Project constraints are restrictions imposed on the project, such as time, cost, and scope.

Cost and schedule performance indexes should be as close to 1 as possible. A larger value, such as 2.12, means that the schedule duration estimates were likely bloated or incorrect to begin with.

Answer option B is incorrect. This is not the best choice for this question.

Answer option C is incorrect. The number should not be close to 100; it should be close to 1.

Answer option D is incorrect. While Mark may have crashed the schedule and driven up costs to achieve the SPI value, a more likely reason is that the time estimates were bloated.

The cost variance for the project is -$51,000. You can find the cost variance by using the formula earned value minus planned value. In this instance, it is: CV = EV - AC = (0.60* 2,456,900) - 1,525,140 = -51,000

Answer option C is incorrect. -$85,000 is the project's variance at completion.

Answer option A is incorrect. $122,845 is the project's schedule variance.

Answer option D is incorrect. There is a cost variance on this project of -$51,000.

The schedule performance index shows how well the project is performing on its schedule goals. The SPI can be found by dividing the earned value by the planned value. In this instance, it is $2,025,000 divided by $2,250,000 for .90. The closer to 1, the better the performance. Schedule performance index (SPI) is the measure of schedule efficiency on a project. It is used in trend analysis to predict future performance. SPI is the ratio of earned value to planned value. The SPI is calculated based on the following formula: SPI = Earned Value (EV) / Planned Value (PV) If the SPI value is greater than 1, it indicates better than expected performance, whereas if the value is less than 1, it shows poor performance. The SPI value of 1 indicates that the project is right on target.

Answer option B is incorrect. 0.98 is the cost performance index.

Answer option A is incorrect. 1.02 is the to-complete performance index.

Answer option D is incorrect. -$108,120 is the variance at completion based on current performance.

The project will need $1,087,497.74 more to complete. This formula, the estimate to complete, is estimate at completion minus the actual costs. Here,

CPI = EV/AC

= (0.40*2,208,456)/725,000

= 1.21846, and

ETC = EAC - AC

= (BAC/CPI) - AC

= (2,208,456/1.21846) - 725,000

= 1,812,497.74 - 725,000

= 1,087,497.74

The estimate to complete (ETC) is the expected cost needed to complete all the remaining work for a scheduled activity, a group of activities, or the project. ETC helps project managers predict what the final cost of the project will be upon completion. The formula for the ETC is EAC- A

C. The EAC is BAC/CPI.

The estimate at completion can be calculated by dividing the budget at completion by the cost performance index. Here,

CPI =EV/AC

= (0.40*2,208,456)/725000

= 1.21846

EAC = BAC/CPI

= 2,208,456/1.21846

= 1,812,498

What is Estimate at Completion (EAC)? Estimate at Completion (EAC) is a field that displays the final cost of the project including the actual costs and the forecast of remaining costs based on the cost performance index (CPI) so far. The formula used to calculate this estimate is as follows: ACWP+(BAC-BCWP)/CPI
