When the project manager elects to use fast tracking the project manager is allowing phases of the project to overlap. When phases overlap there is added risk to the project. Fast tracking is a technique for compressing project schedule. In fast tracking, phases are overlapped that would normally be done in sequence. It is shortening the project schedule without reducing the project scope.

Answer option C is incorrect. Management's greatest concern is about the added risks of fast tracking and not about the SPI.

Answer option A is incorrect. Costs are added when the project manager elects to crash a project.

Answer option D is incorrect. Quality may suffer, but the most prominent concern is the added risks to the project work.

Communication channels are paths of communication with stakeholders in a project. The number of communication channels shows the complexity of a project's communication and can be derived through the formula shown below: Total Number of Communication Channels = n (n-1)/2 where, n is the number of stakeholders. Hence, a project having five stakeholders will have ten communication channels. Putting the number of stakeholders in the formula we can get the required communication channel for the project. It is (78 x 77)/2 for 3,003 communication channels.

Answer options A, B, and D are incorrect. These numbers do not reflect the accurate number of communication channels in the project.

Although this appears to be a simple change the project manager must still follow the rules of the project's change control system. Perform Integrated Change Control is the process of reviewing all change requests, approving changes, and controlling changes to the deliverables and organizational process assets in a project. Perform Integrated Change Control has to do with influencing the things that cause change, determining that the change is required or has happened, and managing the change.

Answer option D is incorrect. Communications management is the execution of the communications management plan.

Answer option A is incorrect. The project change control process not valid as it's the parent of the integrated change control process, which is more accurate for this question.

Answer option C is incorrect. Configuration management is the documentation and control of the product's features and functions.

The critical chain method is similar to the critical path method, but it considers the availability of project resources. The critical path method assumes that the project resources are available for the identified project work in the sequence of the work as defined in the project network diagram. The Critical Chain method is a project management technique in which schedule network analysis is used for the purpose of modifying and determining a set of project schedules to account for more inadequate than estimated project financial resources. This method tends to keep the resources levelly loaded, but requires the resources to be flexible in their start times and to quickly switch between tasks and task chains to keep the whole project on schedule. In the Critical Chain method, projects are completed more rapidly and with better scheduling consistency.

Answer options B, A, and D are incorrect. These are not valid definitions for the critical chain method.

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 instance, the earned value is $234,000 as the project work is 100 percent. The actual costs are $245,000.

Answer option D is incorrect. This is the schedule performance index value.

Answer option A is incorrect. This is the variance at completion for the project.

Answer option C is incorrect. There is enough information to find the answer.

These tools and techniques are used in the Plan communications process. The tools and techniques used in the Distribute information process are as follows: Communication methods: These methods includes individual and group meetings, computer chats, audio and video conferences and other remote communications methods to distribute information. Information distribution tools: Various information distribution tools can be used to distribute information such as electronic tools, electronic conferencing tools, hard copy document distribution etc.

The schedule variance can be found by subtracting the planned value from the earned value. In this instance, it is $170,370 minus $227,160. SV = 170,370 - 227,160 = -56,790 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 A is incorrect. $45,789 is not a valid calculation.

Answer option D is incorrect. -$30,268 is the expected variance at completion.

Answer option C is incorrect. There is enough information to know.
