Activity Risk: Assumptions, Constraints, Risks, and Issues in Project Management

PMBOK v8 Definition

Activity Risk refers to the sets of activity assumptions, constraints, risks, and issues that the project team identifies and manages throughout the project lifecycle. The risk report presents information on sources of overall project risk, together with summary information on identified individual project risks. The team defines the risk thresholds of the project and participates in subsequent risk management activities.

Why It Matters for the Exam

Activity Risk appears frequently in PMI exam questions testing your ability to distinguish between assumptions, constraints, risks, and issues at the activity level. Expect scenario-based questions where you must identify whether a statement describes an assumption (accepted as true), a constraint (limitation), a risk (uncertain event), or an issue (occurred problem). These questions appear in Risk Management and Schedule Management domains.

Key Points to Remember (for the exam)

• Main Input (Monitor & Control): Assumption log, Issue log, Risk register, Risk report, Lessons learned register
• Main Output: Risk report (developed progressively throughout risk processes)
• Key Tools: Questionnaires and surveys (quickly accumulate information from large respondent groups), PESTLE, TECOP, VUCA (for identifying sources of overall project risk)
• Common Confusion: Confusing activity assumptions (accepted as true for planning) with activity constraints (limitations that restrict options)
• Risk Report Contents: Results of Perform Risk Analysis, Plan Risk Responses, Implement Risk Responses, and Monitor Risks
• Risk Thresholds: Defined by the team; determines engagement level and character of stakeholder involvement
• Documentation: Activity assumptions, constraints, risks, and issues are recorded in project documents (assumption log, risk register, issue log)

Typical PMI Exam Example

A project manager is reviewing the schedule for a construction project. The team assumes that permits will be approved within 30 days (assumption), but the local government has a 45-day maximum processing time (constraint). There is a 20% probability the permit will be delayed by 15 days (risk). The permit was denied yesterday (issue). Which document contains all these elements?

Answer: The risk report and project documents (assumption log, issue log, risk register).

PMI Exam Traps

• Trap: Confusing assumptions with constraints Reality: Assumptions are accepted as true for planning; constraints are limitations that restrict options

• Trap: Treating risks (uncertain events) as issues (occurred problems) Reality: Risks have probability; issues have already occurred and require immediate response

• Trap: Thinking the risk report only contains individual risks Reality: The risk report contains both sources of overall project risk AND summary information on individual project risks

• Trap: Confusing activity-level risks with overall project risks Reality: Activity risks affect specific work packages; overall project risks affect the entire project (sources identified via PESTLE, TECOP, VUCA)

Important PMI Connections

Quick Review Questions

1. A project team identifies that a key supplier might delay delivery by two weeks. Is this an assumption, constraint, risk, or issue?

2. During which processes is the risk report developed progressively?

3. What is the difference between an activity assumption and an activity constraint?

4. Which tools help identify sources of overall project risk rather than individual activity risks?

5. When a risk occurs and becomes a problem, which document should it be moved to?
