1. This is similar to a statement of work used in the procurement process. The TOR is used for professional services contracts.

2. PERT uses expected value—or weighted average—of critical path tasks to determine project duration by establishing three estimates: most likely, pessimistic, and optimistic. The formula for PERT is optimistic + pessimistic + (4 × most likely) / 6. PERT is used when activity duration estimates are highly uncertain.

3. CMMI is used to assess and improve the performance of organizations in various areas. CMMI may apply to project management, engineering, organizational development, and more. Generally, five stages of maturity are associated with CMMI: no formal processes in place; basic processes in place; best practices in place and standardized across the organization; best practices in place, standardized, and measurable using quantifiable methods; and continuous, sustained process improvement.

4. An extension of the WBS that contains all the activities of the project and a description of each activity. The activity list is an output of the Define Activities process.

5. This process concerns monitoring and controlling communications throughout the project, including evaluating and controlling the impact messages may carry and making certain the right message is delivered to the right people at the right time.

6. A measure used on flow-based agile projects that measures the time it takes to complete the work once the work is started.

7. Meetings used in the agile project management methodology. They are held daily, usually at the same time, and have a short duration in which team members discuss their work status.

8. This plan establishes policies and procedures for estimating, managing, and controlling project costs. It is an output of the Plan Cost Management process.

9. A method of rating and scoring vendor proposals. Evaluation criteria are an output of the Conduct Procurements process via the source selection criteria, and they are an input to the Conduct Procurements process (as part of the source selection criteria).

10. The PMIS is incorporated as part of the enterprise environmental input to several processes. It is an automated or manual system used to document the project management plan and subsidiary plans, facilitate the feedback process, and revise documents.

11. Failing to meet quality requirements or standards might result in rework (performing the work again to make it conform). Rework might lengthen the project schedule.

12. A payment system is used in the Control Procurements process to issue payment based on the input of seller invoices.

13. This motivational theory says people are motivated by the need for three things: achievement, power, and affiliation.

14. This process assesses the number of work periods needed to complete the project activities. Work periods are usually expressed in hours or days. Large projects might express duration in weeks or months.

15. Appraisal costs are the costs expended to examine the product or process and make certain the requirements are being met. Appraisal costs might include costs associated with aspects such as inspections and testing.

16. Values that are rank-ordered as, for example, high, medium, or low. They are referenced in the Perform Qualitative Risk Analysis process.

17. This technique of Develop Schedule creates the project schedule. It uses a schedule model and other analytical techniques such as critical path and critical chain method, what-if analysis, and resource leveling (all of which are other tools and techniques in this process) to help calculate these dates and the project schedule.

18. Utilizing business analysis techniques, these people meet with stakeholders and document their requirements for the project.

19. A calculation used in CPM to determine early start and early finish dates for activities.

20. This process sequences activities in logical order and determines whether dependencies exist among the activities.

21. These are measurements of deliverables (or certain characteristics of a deliverable) that meet one of two options: conforming or nonconforming. Conforming meets the requirement; nonconforming does not. This is an inspection technique (which is a tool and technique) of the Control Quality process.

22. Describes processes that are repeated. The five process groups are repeated throughout the project's life because of change requests, responses to change, corrective action, and so on.

23. Exploit is a Plan Risk Responses strategy used for risks that pose an opportunity to the project. It involves ensuring that the risk is realized.

24. An input to many processes, organizational process assets typically include the organization's policies, guidelines, processes, procedures, plans, approaches, and standards for conducting work, including project work. Organizational process assets are divided into two categories: processes and procedures and corporate knowledge base.

25. Conflict is the incompatibility of goals, which often leads to one party resisting or blocking the other party from attaining their goals.
