This analysis helps project managers make informed decisions about whether to approve, reject, or modify change requests.
When conducting an impact analysis, project managers must assess several key areas. First, they examine the scope impact to determine if the change will alter project deliverables, requirements, or boundaries. This includes evaluating how the modification affects the work breakdown structure and overall project objectives.
Second, the schedule impact must be evaluated. Project managers analyze whether the change will extend timelines, affect milestone dates, or require adjustments to the critical path. This assessment helps stakeholders understand potential delays and their cascading effects on dependent tasks.
Third, cost implications require thorough examination. Changes often introduce additional expenses through labor, materials, equipment, or other resources. The analysis should quantify these costs and compare them against available budget reserves or contingency funds.
Fourth, resource impact addresses how the change affects team members, equipment availability, and skill requirements. Project managers must determine if current resources can accommodate the change or if additional personnel or tools are necessary.
Fifth, quality considerations ensure that proposed changes do not compromise project standards or deliverable specifications. The analysis evaluates potential effects on testing procedures, acceptance criteria, and overall product quality.
Sixth, risk assessment identifies new risks introduced by the change and evaluates how existing risks might be affected. This includes updating the risk register and developing appropriate response strategies.
The impact analysis results are typically documented and presented to the change control board or appropriate stakeholders for review. This documentation includes recommendations based on the analysis findings, enabling decision-makers to approve changes with full understanding of their consequences. Effective impact analysis supports better project governance and helps maintain control over project baselines throughout the project lifecycle.

What is Impact Analysis for Changes?
Impact analysis for changes is a systematic process used to evaluate the potential consequences of a proposed change to a project. It involves examining how a change request might affect the project's scope, schedule, budget, quality, resources, and risk profile before any decision is made to approve or reject the change.
Why is Impact Analysis Important?
Impact analysis is critical for several reasons:
• Informed Decision Making: It provides stakeholders with comprehensive information to make educated decisions about whether to proceed with a change.
• Risk Mitigation: By understanding potential consequences beforehand, project managers can prepare mitigation strategies and avoid unexpected problems.
• Scope Control: It helps prevent scope creep by ensuring all changes are thoroughly evaluated before implementation.
• Resource Planning: Teams can properly allocate resources and adjust timelines when they understand the full impact of changes.
• Stakeholder Communication: It facilitates transparent communication with stakeholders about what changes will mean for the project.
How Impact Analysis Works
The impact analysis process typically follows these steps:
Step 1: Document the Change Request Record all details about the proposed change, including what is being requested and why.
Step 2: Identify Affected Areas Determine which project components will be affected, including: - Schedule and timeline - Budget and costs - Scope and deliverables - Quality standards - Resources and staffing - Risks and dependencies
Step 3: Analyze the Impact Evaluate the magnitude of effects on each identified area. This includes both positive and negative consequences.
Step 4: Document Findings Create a comprehensive report detailing all potential impacts, alternative approaches, and recommendations.
Step 5: Present to Change Control Board (CCB) Submit the analysis to the appropriate authority for review and decision-making.
Key Elements to Assess During Impact Analysis
• Schedule Impact: Will the change delay the project? Which tasks and milestones are affected?
• Cost Impact: What additional expenses will be incurred? Are there budget implications?
• Scope Impact: How does this change alter project deliverables or requirements?
• Quality Impact: Will the change affect product or service quality standards?
• Resource Impact: Are additional team members, equipment, or materials needed?
• Risk Impact: Does this change introduce new risks or modify existing ones?
• Dependency Impact: Which other tasks, projects, or systems are affected?
Exam Tips: Answering Questions on Impact Analysis for Changes
Tip 1: Remember the Sequence Impact analysis always occurs BEFORE a change is approved. If a question asks what should happen when a change is requested, the answer typically involves conducting impact analysis first.
Tip 2: Know the Triple Constraint Questions often focus on how changes affect scope, time, and cost. Understand that changing one element usually affects the others.
Tip 3: Change Control Board Authority Remember that the CCB reviews impact analysis results and makes approval decisions. The project manager conducts the analysis but may not have final approval authority.
Tip 4: Documentation is Essential Look for answer choices that emphasize documenting the analysis and maintaining records. Proper documentation is always part of the correct process.
Tip 5: Consider All Stakeholders Impact analysis should consider effects on all stakeholders, not just the project team. Questions may test whether you understand this broader perspective.
Tip 6: Watch for Incomplete Processes Incorrect answers often describe skipping steps or implementing changes prior to completing proper analysis. Always choose the thorough, systematic approach.
Tip 7: Understand Baseline Updates After an approved change, project baselines must be updated. Questions may test your knowledge of what happens after impact analysis and approval.
Common Exam Question Scenarios
• A stakeholder requests a new feature - what is the first step? • How should a project manager respond to an urgent change request? • What information should be included in an impact analysis report? • Who has authority to approve changes based on impact analysis?
Remember: The exam tests your understanding of following proper change management procedures, with impact analysis being a fundamental component of that process.
