PMI PMI-SP Practice Test Questions Answers

The project's schedule performance index (SPI) can be found by using the formula; earned value/planned value. The earned value is the percent of the project completed times the BAC. The planned value is the percentage of where the project should be times the budget at completion. In this instance, the formula reads: $450,000/562500 = 0.80. 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 A is incorrect. This value is the project's Cost Performance Index (CPI).

Answer option D is incorrect. This value is the schedule variance for the project.

Answer option C is incorrect. $562,500 is the planned value for the project.

Rolling wave planning is a technique to plan and do the most imminent project work before moving onto the details that are far off in the project schedule and project plan. Rolling wave planning is a technique for performing progressive elaboration planning where the work to be accomplished in the near future is planned in detail at a low level of the work breakdown structure. The work to be performed within another one or two reporting periods in the near future is planned in detail as work is being completed during the current period.

Answer options B and A are incorrect. These are not valid project management terms.

Answer option D is incorrect. Decomposition is the process of breaking down work packages into the activity list.

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.

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.

The limit on each work is an organizational policy for each project. Policies, rules, and organizational requirements are the enterprise environmental factors.

Answer option D is incorrect. Organizational process assets are things that have been created for the project manager, such as software, templates, guidelines, and other resources that will assist the project manager in completing the project.

Answer option C is incorrect. While this could be a resource limitation, it is not a valid project management term. Resource leveling heuristics or a project constraint would have been acceptable answers.

Answer option A is incorrect. Expert judgment happens, when the project manager relies on someone with more knowledge on a topic to help the project manager make the best project decision.
