Questions
A. Framework, authority, and initiation
Correct answer: Routine production is operations; the temporary redesign is a project because it produces a unique result.
Routine repeated production is operations; the temporary redesign effort with a defined result is a project. See §1: The project management framework.
Correct answer: Coordinating related projects produces benefits unavailable from managing each separately.
Coordinated related work yields benefits unavailable from managing each separately. See §1: The project management framework.
Correct answer: Weak matrix; functional-manager authority predominates.
Weak matrix: functional-manager authority predominates. See §2: Organizations, authority, and PMOs.
Correct answer: Supportive; controlling; directive.
Optional assistance is supportive; enforced standards/compliance make the second controlling; direct project management makes the third directive. Supportive; controlling; directive. See §2: Organizations, authority, and PMOs.
Correct answer: Scope, schedule, quality, budget, resources, and risk; scope changes can also change effort, cost, time, or risk.
Scope, schedule, quality, budget, resources, risk. Added scope may require labor, time, money, or additional risk/quality work. See §3: Success, constraints, and competencies.
Correct answer: No. Cohesion is one measure; customer acceptance and other objectives also matter.
No. Cohesion is one success measure; acceptance and other objectives still matter. See §3: Success, constraints, and competencies.
Correct answer: A charter includes the need, objectives, alignment, high-level scope/priorities/assumptions, and early estimates; the sponsor authorizes/supports and the PM manages day to day.
Need/solution, objectives, alignment, high-level scope/priorities/assumptions and early estimates. Sponsor authorizes/supports/funds; PM manages day-to-day work. See §4: Initiation: business need, charter, and priorities.
Correct answer: ROM cost lower ($): 6,000; ROM cost upper ($): 24,000; ROM duration lower (days): 3; ROM duration upper (days): 12
ROM uses half to twice the base in the course: $12,000/2 = $6,000; $12,000×2 = $24,000; 6/2 = 3 days; 6×2 = 12 days. $6,000–$24,000; 3–12 days. The workbook confirms this course range; independent certification alignment remains unverified. See §4: Initiation: business need, charter, and priorities.
Correct answer: It fails to identify which constraint can move when tradeoffs become unavoidable.
It does not identify which constraint can move when tradeoffs are unavoidable. See §4: Initiation: business need, charter, and priorities.
B. Scope, responsibility, and estimates
Correct answer: Who, what, when, and how; a kickoff builds shared goals, roles, expectations, and communication.
Who, what, when, how. Kickoff establishes shared goals, roles, expectations, and communication. See §5: Team, stakeholders, communication, and kickoff.
Correct answer: Eight windows describes product scope; purchasing and installing them describes project scope.
Feature: product scope. Required work: project scope. See §6: Scope planning and the WBS.
Correct answer: WBS; work package; unique identifiers for WBS components.
WBS; work package; unique component-identification system. See §6: Scope planning and the WBS.
Correct answer: Responsibility Assignment Matrix; Responsible, Approver/Authority, Contributor, Informed; R ensures completion and may coordinate contributors.
Responsibility Assignment Matrix; Responsible, Approver/Authority, Contributor, Informed in this course variant. R ensures completion and may coordinate contributors. The embedded workbook image confirms these course A/C labels. See §7: Assigning responsibility: RAM and RACI.
Correct answer: 12 effort-hours → whole workdays: 2; 18 effort-hours → whole workdays: 3
Round positive effort up to whole eight-hour workdays: ceil(12/8) = 2 and ceil(18/8) = 3. This is the class convention, not an assumption about every staffing arrangement. Two and three whole workdays. Resource availability, staffing, calendar, and wait time can alter the relationship. See §8: Estimating effort, duration, and uncertainty.
Correct answer: Triangular estimate (hours): 9; PERT estimate (hours): 8
Triangular = (4+7+16)/3 = 9. PERT = (4+4×7+16)/6 = 8; the most-likely estimate receives four weights. Triangular = 27/3 = 9 hours. PERT = (4 + 28 + 16)/6 = 8 hours. See §8: Estimating effort, duration, and uncertainty.
C. Dependencies, scheduling, and resources
Correct answer: FS; SS; FF; SF, in the order given.
FS links A’s finish to B’s start; SS links their starts; FF links their finishes; SF links A’s start to B’s finish. FS; SS; FF; SF. See §9: Dependencies, leads, and lags.
Correct answer: Yes. External describes control/boundary; mandatory describes required logic, so the classifications can combine.
Yes. External describes control/boundary; mandatory describes whether the logic is required. See §9: Dependencies, leads, and lags.
Correct answer: Requirements → test procedures → test is 58 days; the other branch has six shared float days, not twelve.
The test-procedures path is 17+29+12 = 58 days; the design/build path is 17+15+8+12 = 52. Their six-day difference is one shared allowance along the shorter branch. Requirements → test procedures → test = 58 days. Six days on the other branch; shared allowance, not 12. See §10: Critical path, early/late dates, and float.
Correct answer: Design finish (day): 38; Build finish (day): 46; Project finish (day): 58
Design: 23+15 = 38. Build: 38+8 = 46. Test waits for both branches, so its finish remains 46+12 = 58. The delayed branch uses the six-day shared allowance. Design finishes day 38; build can finish day 46; test still finishes day 58. All six available days are consumed. See §10: Critical path, early/late dates, and float.
Correct answer: Fast tracking overlaps work and may increase rework; crashing adds useful resources and usually cost; constraint priorities and dependencies guide the choice.
Overlap with rework risk versus added resources/cost. Constraint priorities and actual dependencies help select a feasible option. See §11: Gantt charts and schedule compression.
Correct answer: Weekly load with 80-hour commitment (hours/week): 40; Weekly load with 100-hour commitment (hours/week): 45; Excess in second scenario (hours/week): 5
First load: 80/4 + 30/1.5 = 20+20 = 40. Second load: 100/4 + 30/1.5 = 25+20 = 45, which exceeds 40 by 5. 20 + 20 = 40 hours/week, at threshold. With 100/4 = 25, total = 45, five hours above capacity. See §12: Resource loading and leveling.
Correct answer: Loading shows assigned demand; overload remedies address excess demand; available float may allow shifts without extending the finish.
Loading reveals assigned demand. Leveling/remedies address excess demand. Available float may shift noncritical work without extending the finish. See §12: Resource loading and leveling.
Correct answer: Analogous; parametric; bottom-up.
A similar prior-project total is analogous. A calibrated historical rate per unit is parametric. Adding detailed estimates upward is bottom-up. Analogous; parametric; bottom-up. See §13: Cost estimating, budgets, and the S-curve.
D. Costs, risk, and execution
Correct answer: Day 3 labor ($): 560; Day 3 total ($): 2,560; Cumulative through day 3 ($): 5,230
Labor: 16×$25 + 4×$40 = $560. Daily total: $560+$2,000 = $2,560. Cumulative: $2,670+$2,560 = $5,230. The S-curve uses cumulative planned cost, rather than only day 3 spending. Labor $560; day total $2,560; cumulative $5,230. Plot cumulative planned cost against time. See §13: Cost estimating, budgets, and the S-curve.
Correct answer: Expected cost ($): 3,000; Expected delay (days): 2
0.20×$15,000 = $3,000; 0.05×40 days = 2 days. Adding them into one number would mix incompatible units. $3,000 and 2 days. Retain separate units. See §14: Risk analysis and response planning.
Correct answer: Qualitative analysis ranks probability/impact for prioritization; qualitative comes before quantitative in this course sequence.
Rank/prioritize probability and impact. Qualitative before quantitative in the course sequence. See §14: Risk analysis and response planning.
Correct answer: Transfer; avoid; mitigate; escalate; active acceptance with contingency.
Insurance transfers financial exposure; eliminating the threat is avoidance; reducing likelihood is mitigation; referring beyond your authority is escalation; retaining risk with backup action is active acceptance with contingency. Transfer; avoid; mitigate; escalate; active acceptance with contingency. See §14: Risk analysis and response planning.
Correct answer: Residual risk remains; contingency is a backup action; a trigger is an observable signal; an owner monitors/responds; reserve provides retained-risk capacity or funds.
Remaining risk; backup action; observable signal; assigned watcher/responsible person; retained-risk capacity/funds. See §14: Risk analysis and response planning.
Correct answer: Forming → storming → norming → performing → adjourning; performing is not guaranteed.
Forming, storming, norming, performing, adjourning. No; talent, cohesion, time, and retention matter. See §15: Execution and team development.
E. Reporting, change, and closing
Correct answer: Progress = interval change; status = current snapshot; forecast = future projection; monitoring = collect/report, controlling = analyze/correct, executing = do the work.
Change over an interval; current snapshot; future projection. Collect/report; analyze/correct; do the work. See §16: Reporting, monitoring, and controlling.
Correct answer: Log a formal request, evaluate benefit and impacts, and have the CCB/designated authority accept, reject, or defer; notify and integrate approved changes.
Formal request, log, authorized review of benefit/impacts, accept/reject/defer, notify the requester, and integrate accepted changes. CCB or designated authority decides. See §17: Change control.
Correct answer: Closing includes final actuals/reports, documentation and archiving; lessons should capture good practices and improvements with useful context.
Final reporting, actuals, documentation and archiving remain. Capture good practices and improvements with enough context for future use. See §18: Closing and lessons learned.
F. Workbook additions
Correct answer: A temporary initiative in a unique context undertaken to create value; outputs support value, and acceptance alone need not prove benefits were realized.
A temporary initiative in a unique context undertaken to create value. Outputs are a way to produce value; acceptance alone need not prove benefits were realized. See §1: The project management framework.
Correct answer: Domains group governance, scope, schedule, finance, stakeholders, resources, and risk; principles guide behavior through a holistic view, value, embedded quality, accountable leadership, sustainability, and empowered culture.
Domains: governance, scope, schedule, finance, stakeholders, resources, risk. Principles: holistic view; value; embedded quality; accountable leadership; sustainability; empowered culture. Principles guide behavior; domains group activities; focus areas organize major functions. See §1: The project management framework.
Correct answer: Value realization concerns intended benefits after delivery; tailoring deliberately adapts approach, governance, and processes to the work rather than using every technique.
Realize the intended benefit after delivery; deliberately adapt approach/governance/processes to the work. No—choose what fits. See §1: The project management framework.
Correct answer: Progressive elaboration refines as information improves; rolling wave details the near phase with broader later work; RAM steps are list skills, select people, discuss roles, gain commitments, document.
Refine as information improves; detail the near phase while later work remains broad. RAM: list skills, select people, discuss roles, gain commitments, document. See §1: The project management framework, §7: Assigning responsibility: RAM and RACI.
Correct answer: ROM lower ($): 5,000; ROM upper ($): 20,000; Budgetary lower ($): 9,000; Budgetary upper ($): 12,500; Definitive lower ($): 9,500; Definitive upper ($): 11,000
ROM: $10,000×0.5 to ×2. Budgetary: ×0.90 to ×1.25. Definitive: ×0.95 to ×1.10. These are the workbook ranges for this course. $5,000–$20,000; $9,000–$12,500; $9,500–$11,000. Fixed does not shorten with added people; variable may. Level of effort is listed but not explained in this workbook. See §8: Estimating effort, duration, and uncertainty.
Correct answer: Design free float (days): 0; Build free float (days): 6
Design EF = 32 equals build ES = 32, so design free float is 0. Build EF = 40; test ES = 46, so build free float is 6. Total float protects the project finish; free float protects the successor early start. Design 0; build 6. Delaying design delays build's early start while six shared days still protect project finish. See §10: Critical path, early/late dates, and float.
Correct answer: Owner, Approval, Implementer; I means doing work in this sample's legend, not Informed.
Owner, Approval, Implementer. It is a different letter model whose legend defines I as doing work. See §7: Assigning responsibility: RAM and RACI.
Correct answer: Finalize: validate, approvals, archive, communicate. Control: collect actuals/forecasts, compare, analyze, correct, revise as authorized, report.
Validate, approvals, archive, communicate. Control: collect actuals/forecasts; compare; analyze cause/impact; correct; revise as authorized; report. See §14: Risk analysis and response planning, §16: Reporting, monitoring, and controlling.
Correct answer: Total residual expected delay (days): 1.25
0.05×20 + 0×2 + 0.25×1 = 1 + 0 + 0.25 = 1.25 days. 1 + 0 + 0.25 = 1.25 days, the sample's schedule contingency. See §14: Risk analysis and response planning.
Correct answer: Defer is also an outcome; closing can terminate unfinished work or close a phase or contract.
Defer; accepted changes are notified and integrated. Yes—closing can terminate a project before completion, or close a phase/contract. See §17: Change control, §18: Closing and lessons learned.

Explained answer key
A. Framework, authority, and initiation
1. Routine repeated production is operations; the temporary redesign effort with a defined result is a project. See §1: The project management framework.
2. Coordinated related work yields benefits unavailable from managing each separately. See §1: The project management framework.
3. Weak matrix: functional-manager authority predominates. See §2: Organizations, authority, and PMOs.
4. Optional assistance is supportive; enforced standards/compliance make the second controlling; direct project management makes the third directive. Supportive; controlling; directive. See §2: Organizations, authority, and PMOs.
5. Scope, schedule, quality, budget, resources, risk. Added scope may require labor, time, money, or additional risk/quality work. See §3: Success, constraints, and competencies.
6. No. Cohesion is one success measure; acceptance and other objectives still matter. See §3: Success, constraints, and competencies.
7. Need/solution, objectives, alignment, high-level scope/priorities/assumptions and early estimates. Sponsor authorizes/supports/funds; PM manages day-to-day work. See §4: Initiation: business need, charter, and priorities.
8. ROM uses half to twice the base in the course: $12,000/2 = $6,000; $12,000×2 = $24,000; 6/2 = 3 days; 6×2 = 12 days. $6,000–$24,000; 3–12 days. The workbook confirms this course range; independent certification alignment remains unverified. See §4: Initiation: business need, charter, and priorities.
9. It does not identify which constraint can move when tradeoffs are unavoidable. See §4: Initiation: business need, charter, and priorities.
B. Scope, responsibility, and estimates
10. Who, what, when, how. Kickoff establishes shared goals, roles, expectations, and communication. See §5: Team, stakeholders, communication, and kickoff.
11. Feature: product scope. Required work: project scope. See §6: Scope planning and the WBS.
12. WBS; work package; unique component-identification system. See §6: Scope planning and the WBS.
13. Responsibility Assignment Matrix; Responsible, Approver/Authority, Contributor, Informed in this course variant. R ensures completion and may coordinate contributors. The embedded workbook image confirms these course A/C labels. See §7: Assigning responsibility: RAM and RACI.
14. Round positive effort up to whole eight-hour workdays: ceil(12/8) = 2 and ceil(18/8) = 3. This is the class convention, not an assumption about every staffing arrangement. Two and three whole workdays. Resource availability, staffing, calendar, and wait time can alter the relationship. See §8: Estimating effort, duration, and uncertainty.
15. Triangular = (4+7+16)/3 = 9. PERT = (4+4×7+16)/6 = 8; the most-likely estimate receives four weights. Triangular = 27/3 = 9 hours. PERT = (4 + 28 + 16)/6 = 8 hours. See §8: Estimating effort, duration, and uncertainty.
C. Dependencies, scheduling, and resources
16. FS links A’s finish to B’s start; SS links their starts; FF links their finishes; SF links A’s start to B’s finish. FS; SS; FF; SF. See §9: Dependencies, leads, and lags.
17. Yes. External describes control/boundary; mandatory describes whether the logic is required. See §9: Dependencies, leads, and lags.
18. The test-procedures path is 17+29+12 = 58 days; the design/build path is 17+15+8+12 = 52. Their six-day difference is one shared allowance along the shorter branch. Requirements → test procedures → test = 58 days. Six days on the other branch; shared allowance, not 12. See §10: Critical path, early/late dates, and float.
19. Design: 23+15 = 38. Build: 38+8 = 46. Test waits for both branches, so its finish remains 46+12 = 58. The delayed branch uses the six-day shared allowance. Design finishes day 38; build can finish day 46; test still finishes day 58. All six available days are consumed. See §10: Critical path, early/late dates, and float.
20. Overlap with rework risk versus added resources/cost. Constraint priorities and actual dependencies help select a feasible option. See §11: Gantt charts and schedule compression.
21. First load: 80/4 + 30/1.5 = 20+20 = 40. Second load: 100/4 + 30/1.5 = 25+20 = 45, which exceeds 40 by 5. 20 + 20 = 40 hours/week, at threshold. With 100/4 = 25, total = 45, five hours above capacity. See §12: Resource loading and leveling.
22. Loading reveals assigned demand. Leveling/remedies address excess demand. Available float may shift noncritical work without extending the finish. See §12: Resource loading and leveling.
23. A similar prior-project total is analogous. A calibrated historical rate per unit is parametric. Adding detailed estimates upward is bottom-up. Analogous; parametric; bottom-up. See §13: Cost estimating, budgets, and the S-curve.
D. Costs, risk, and execution
24. Labor: 16×$25 + 4×$40 = $560. Daily total: $560+$2,000 = $2,560. Cumulative: $2,670+$2,560 = $5,230. The S-curve uses cumulative planned cost, rather than only day 3 spending. Labor $560; day total $2,560; cumulative $5,230. Plot cumulative planned cost against time. See §13: Cost estimating, budgets, and the S-curve.
25. 0.20×$15,000 = $3,000; 0.05×40 days = 2 days. Adding them into one number would mix incompatible units. $3,000 and 2 days. Retain separate units. See §14: Risk analysis and response planning.
26. Rank/prioritize probability and impact. Qualitative before quantitative in the course sequence. See §14: Risk analysis and response planning.
27. Insurance transfers financial exposure; eliminating the threat is avoidance; reducing likelihood is mitigation; referring beyond your authority is escalation; retaining risk with backup action is active acceptance with contingency. Transfer; avoid; mitigate; escalate; active acceptance with contingency. See §14: Risk analysis and response planning.
28. Remaining risk; backup action; observable signal; assigned watcher/responsible person; retained-risk capacity/funds. See §14: Risk analysis and response planning.
29. Forming, storming, norming, performing, adjourning. No; talent, cohesion, time, and retention matter. See §15: Execution and team development.
E. Reporting, change, and closing
30. Change over an interval; current snapshot; future projection. Collect/report; analyze/correct; do the work. See §16: Reporting, monitoring, and controlling.
31. Formal request, log, authorized review of benefit/impacts, accept/reject/defer, notify the requester, and integrate accepted changes. CCB or designated authority decides. See §17: Change control.
32. Final reporting, actuals, documentation and archiving remain. Capture good practices and improvements with enough context for future use. See §18: Closing and lessons learned.
F. Workbook additions
33. A temporary initiative in a unique context undertaken to create value. Outputs are a way to produce value; acceptance alone need not prove benefits were realized. See §1: The project management framework.
34. Domains: governance, scope, schedule, finance, stakeholders, resources, risk. Principles: holistic view; value; embedded quality; accountable leadership; sustainability; empowered culture. Principles guide behavior; domains group activities; focus areas organize major functions. See §1: The project management framework.
35. Realize the intended benefit after delivery; deliberately adapt approach/governance/processes to the work. No—choose what fits. See §1: The project management framework.
36. Refine as information improves; detail the near phase while later work remains broad. RAM: list skills, select people, discuss roles, gain commitments, document. See §1: The project management framework, §7: Assigning responsibility: RAM and RACI.
37. ROM: $10,000×0.5 to ×2. Budgetary: ×0.90 to ×1.25. Definitive: ×0.95 to ×1.10. These are the workbook ranges for this course. $5,000–$20,000; $9,000–$12,500; $9,500–$11,000. Fixed does not shorten with added people; variable may. Level of effort is listed but not explained in this workbook. See §8: Estimating effort, duration, and uncertainty.
38. Design EF = 32 equals build ES = 32, so design free float is 0. Build EF = 40; test ES = 46, so build free float is 6. Total float protects the project finish; free float protects the successor early start. Design 0; build 6. Delaying design delays build's early start while six shared days still protect project finish. See §10: Critical path, early/late dates, and float.
39. Owner, Approval, Implementer. It is a different letter model whose legend defines I as doing work. See §7: Assigning responsibility: RAM and RACI.
40. Validate, approvals, archive, communicate. Control: collect actuals/forecasts; compare; analyze cause/impact; correct; revise as authorized; report. See §14: Risk analysis and response planning, §16: Reporting, monitoring, and controlling.
41. 0.05×20 + 0×2 + 0.25×1 = 1 + 0 + 0.25 = 1.25 days. 1 + 0 + 0.25 = 1.25 days, the sample's schedule contingency. See §14: Risk analysis and response planning.
42. Defer; accepted changes are notified and integrated. Yes—closing can terminate a project before completion, or close a phase/contract. See §17: Change control, §18: Closing and lessons learned.
Using your results
Review missed concepts using their linked guide sections and cited recordings/workbook pages. Recompute calculations from the givens rather than memorizing their answers. The score checks concept choices and numeric results; explain the remaining reasoning out loud or in your own notes.
Course qualifications matter: ROM ranges, eight-hour rounding, RACI labels, and the FS-only zero-lag network are the stated course conventions/examples. Independent certification alignment remains unverified. The workbook lists level of effort without defining it; that remaining gap is retained in the explanation.
