Explanation:
The activity cost estimates review is valuable in identifying risks as it provides a quantitative assessment of the expected cost to complete the scheduled activities and is expressed as a range, with a width of the range indicating the degrees of risk.
Incorrect Answers:
A: The activity duration estimates review is valuable in identifying risks associated to the time allowances for the activities or projects as a whole, with a width of the range indicating the degrees of risk.
B: This is the output of plan risk management process. A Risk management plan is a document arranged by a project manager to estimate the effectiveness, predict risks, and build response plans to mitigate them. It also consists of the risk assessment matrix.
C: The cost management plan sets how the costs on a project are managed during the project's lifecycle. It defines the format and principles by which the project costs are measured, reported, and controlled. The cost management plan identifies the person responsible for managing costs, those who have the authority to approve changes to the project or its budget, and how cost performance is quantitatively calculated and reported upon.

Explanation:
For effective post-implementation review the business measurements up front is established during the project.
Incorrect Answers:
B: Executing sufficient number of business cycles in the new system is done after the completion of the project.
C, D: Identifying the information to be reviewed and information collected during each stage of project is done in pre-project phase and not during project for effective post-implementation review.

Explanation:
Monitoring tools have to be able to keep up with the growth of an enterprise and meet anticipated growth in process, complexity or transaction volumes; this is ensured by the scalability criteria of the monitoring tool.
Incorrect Answers:
B: For software to be effective, it must be customizable to the specific needs of an enterprise. Hence customizability ensures that end users can adapt the software.
C: It ensures that monitoring software is able to change at the same speed as technology applications and infrastructure to be effective over time.
D: The impact on performance has nothing related to the ability of monitoring tool to keep up with the growth of enterprise.

Explanation:
Decision tree analysis is a risk analysis tool that can help the project manager in determining the best risk response. The tool can be used to measure probability, impact, and risk exposure and how the selected risk response can affect the probability and/or impact of the selected risk event. It helps to form a balanced image of the risks and opportunities connected with each possible course of action. This makes them mostly useful for choosing between different strategies, projects, or investment opportunities particularly when the resources are limited. A decision tree is a decision support tool that uses a tree-like graph or model of decisions and their possible consequences, including chance event outcomes, resource costs, and utility.
Incorrect Answers:
A: Project network diagrams help the project manager and stakeholders visualize the flow of the project work, but they are not used as a part of risk response planning.
B: The Delphi technique can be used in risk identification, but generally is not used in risk response planning. The Delphi technique uses rounds of anonymous surveys to identify risks.
D: Cause-and-effect diagrams are useful for identifying root causes and risk identification, but they are not the most effective ones for risk response planning.
