PMI Scheduling Professional Exam Practice Test

Answer : A

An activity is an individual element of work that is logically linked to other activities to

form the schedule. Its primary characteristics include an overall duration based upon the resources

applied to it (manpower, material, and equipment), as well as a start and

completion date that is tied to a work calendar. It also has a relationship with other activities

(predecessors and successors).

Answer : D

This is an example of corrective action. The project team will fix the mistake and they

have learned from their mistake so it won't happen again.

Answer option C is incorrect. Risk mitigation is defined as monies spent or actions taken to reduce

the probability and impact of an identified

risk event.

Answer option A is incorrect. A risk response is an action to counteract an identified risk.

Answer option B is incorrect. There may be some team development happening in this instance but

we don't have enough information to know

for certain. Team development is an activity that brings the whole team cohesion, interdependency,

and trust.

Answer : B, C

According to the scenario, you can use the following inputs in order to generate

performance reports:

WPI: Work performance information is the data gathered on the status of the project schedule

activities that are performed to

accomplish the project work. This data is collected as part of the Direct and Manage Project

Execution processes. WPI includes the

following:

Deliverables status

Schedule Progress

Costs incurred

WPM: Work performance measurements are created from the work performance information.

WPMs are an output of Control schedule,

Control cost, and Control scope processes, which are monitoring and controlling processes. WPMs

consist of planned versus actual

performance indicators with respect to scope, schedule, and cost. They are documented and

communicated to the stakeholders and are

used to make project activity metrics, such as the following:

Planned vs. Actual Technical performance and Scope performance

Planned vs. Actual Schedule performance

Planned vs. Actual Cost performance

Answer option A is incorrect. Variance analysis is an after-look at what caused a difference between

the baseline and the actual performance.

It is one of the tools and techniques used for report performance.

Answer option D is incorrect. Change requests are requests to expand or reduce the project scope,

modify policies, processes, plans, or

procedures, modify costs or budgets or revise schedules. These requests for a change can be direct

or indirect, externally or internally

initiated, and legally or contractually imposed or optional. A Project Manager needs to ensure that

only formally documented requested

changes are processed and only approved change requests are implemented.

Answer : B

Fred should add lag time to each painting activity. Since lag time is waiting time, Fred

will have to wait twenty-four hours after the priming is

finished before he can start painting.

What is a lag?

A lag directs a delay in the successor activity. Lags require the dependent activity to have added

either to the start date or

to the finish date of the activity. For example, in a project of making radio-controlled airplanes, after

applying glue and

pasting stickers, it requires twenty-four hours to dry the glue. Any activity can be started after that

only. This period, of

twenty-four hours, is a lag.

Answer option C is incorrect. There is no reason to add an intermediary task as waiting. Adding lag

time is the most appropriate as there are

fewer activities to manage.

Answer option D is incorrect. Priming all of the room first and then painting all of the rooms would

cause Fred to readjust the entire

sequencing of activities. In addition, we do not know the reason why Fred has scheduled all the

rooms to be primed and then painted. There

may be successor activities in the project that need to enter each room, such as carpeting, as soon

as a room has been painted. If that were

the case the additional activities would have to wait for all of the priming to be completed and then

the sequential rooms to be painted before

they could start.

Answer option A is incorrect. Lead time actually moves activities closer together rather than farther

apart. Lead time would cause the painting

and priming activities to overlap, something that Fred does not want to happen.

What is a lead?

A lead allows an acceleration of the successor activity. It works just the opposite of lag. For example,

in a software

application project, before designing is fully completed for first phase, a program development

group can start this phase

programming. This overlapping of timing is a lead.

Answer : C

According to the question, you are required to calculate the schedule performance

index (SPI) of the project. 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. Here, SPI is calculated as

follows:

SPI = EV / PV

= 425/400

= 1.0625

As the SPI (1.0625) is greater than 1, it shows that the schedule performance is better than

expected.

What is BCWP (or EV)?

Budgeted cost of work performed (BCWP) or Earned Value (EV) is the value of completed work. It is

the budgeted amount

for the work actually completed on the schedule activity during a given time period.

What is BCWS (or PV)?

Budgeted Cost of Work Scheduled (BCWS) or Planned Value (PV) is the authorized budget assigned

to the scheduled work

to be accomplished for a schedule activity or Work Breakdown Structure (WBS) component.

What is ACWP (or AC)?

Actual cost of work performed (ACWP) or Actual Cost (AC) is the total costs actually incurred and

recorded in accomplishing

work performed during a given time period for a schedule activity. It is the cost of the work to date,

including direct and

indirect costs. AC is money that has actually been expended to date.

Answer : A

This happens when most of the stakeholders are concerned about risks.

Risk factors are determined for the scope of the project, requirements, design and strategy,

technology, processes (for development,

payment, change management, risk management, and closing the project), and conditions of the

project.

Risk factors are high when most of the stakeholders have concerns. Even if one important feature of

a project appears too difficult to execute,

the risk is high. Issues like acceptable type of bugs and number of bugs for user acceptance, terms

for closing the project, payments not being

clear or misunderstood, make the project highly risky.

Answer option B is incorrect. Risks are low when issues like the format of the forms are not finalized

but the functionality is thoroughly

understood and solutions are approved.

Answer option D is incorrect. Risks are rated medium when a very small number of stakeholders

have a few concerns. For example, the

development team may not have very advanced knowledge of the technology but could provide

some work around. Another could be that the

customer's people cannot finalize a few unimportant workflows.

Answer option C is incorrect. It is an invalid answer.

Answer : B

The critical path is discovered by summing the duration of each activity node in each

chain of activities in the project network diagram. In this

figure, the critical path is ACFGJ, which is 26 days, the longest chain of activities in the project.

Answer option A is incorrect. This path's duration is 22 days.

Answer option D is incorrect. This path's duration is 23 days.

Answer option C is incorrect. This path's duration is 15 days.
