In construction project management, scope describes the detailed set of deliverables or features of a project. The scope outlines the project’s goals, deliverables, tasks, costs, deadlines, and resources. However, during a project life cycle, changes may occur requiring alterations to the initial project scope. This is known as a scope change.
B. Impact of Scope Changes
- 1. Time and Schedule Impacts
Increases in project scope often lead to time extensions. For example, an addition of a new building feature might require an extended timeline to complete. - 2. Budget and Resource Impacts
Scope enlargement typically leads to increased budget and resource utilization. For instance, if the project scope changes to include new high-end materials, this will directly affect the project budget and may require additional manpower for installation. - 3. Risk and Quality Impacts
An increase in project scope also increases risk and potentially affects the project’s quality. More complex projects pose more risks, and rushed schedules to accommodate scope changes can compromise the quality of work.
C. Evaluating Scope Changes
- 1. Impact Analysis
When a change request is received, the first step should be to conduct an impact analysis. This process involves assessing how the proposed change will affect the project’s time, budget, resources, risks, and quality.
Table 1: Impact Analysis Example
| Impact Type | Before Change | After Change |
|---|---|---|
| Time | 6 months | 7 months |
| Budget | $200,000 | $220,000 |
| Resources | 30 workers | 35 workers |
| Risk Level | Moderate | High |
| Quality | High standard | High standard |
- 2. Change Control Board
After completing the impact analysis, the next step is to consult the Change Control Board (CCB). The CCB is a formally chartered group responsible for reviewing, evaluating, approving, delaying, or rejecting changes to the project, and for recording and communicating such decisions. - 3. Project Change Request
If the CCB approves the scope change, a Project Change Request (PCR) is then developed. The PCR highlights the specifics of the scope change, the impacts, the alternative solutions, and the appropriate action.
In conclusion, the ability to evaluate scope changes relative to the core outcomes is a critical skill for any PMI-CP. Scope changes should not be taken lightly as they can gravely affect a project’s timeframe, budget, resources, risks, and quality.

Interview Questions
What is a scope change in project management?
A scope change refers to any alteration or amendment to the initial agreed-upon project scope. It could include changes in objectives, deliverables, or timeframe which can affect the progress, budget, schedule, and performance of a project.
How does evaluating scope changes relate to core outcomes?
Evaluating scope changes is necessary to ensure core outcomes align with the original project goals and objectives. It helps assess the potential impacts of these changes on the project’s cost, schedule, quality, risks, and resources, and ensures the project remains aligned with its strategic objectives.
What is a Change Control Board (CCB) in the context of project scope management?
A Change Control Board (CCB) is a formally chartered group responsible for reviewing, evaluating, approving, delaying, or rejecting changes to the project, including project scope changes. The CCB plays a crucial role in maintaining the balance between project scope and project objectives.
How should a PMI-CP professional respond if a scope change is requested?
A PMI-CP professional should document the requested change, assess its impact on the project’s cost, schedule, quality, and resources, and submit it to the Change Control Board (CCB). After the CCB’s decision, it’s the PMI-CP’s responsibility to communicate this to all relevant stakeholders and adjust the project plan accordingly.
What tools and techniques are used to evaluate scope changes?
Tools and techniques include meetings with stakeholders, expert judgment, cost-benefit analysis, risk assessment, and impact analysis.
Why is it important to document the scope change?
Documenting scope changes is crucial as it provides a record of what was requested, the assessment results, the rationale behind the decision made, and eventual project adjustments. It helps to maintain transparency, provides a foundation for future project decisions, and supports project knowledge and learning.
What is the role of a Change Management Plan in evaluating scope changes?
A Change Management Plan outlines the process to submit a change request, review and evaluate it, assess its impacts, and either approve or reject it. It provides a structured process to control how any changes, including scope changes, are managed throughout the project lifecycle.
What could be the possible impacts of scope changes on the core outcomes of a project?
Scope changes can affect the project’s cost, schedule, quality, resources, and risk. An increase in project scope could mean an increase in cost and time needed to deliver the project. It could also lead to a change in required resources, impact project quality, or introduce new risks.
What are the key elements of a scope change request?
Key elements of a scope change request include a description of the change, decision-makers, the business rationale, cost and time estimates, impact on operational areas, effects on stakeholders, and a contingency plan.
What is the result of not properly evaluating and managing scope changes?
If not properly evaluated and managed, scope changes can lead to scope creep, where uncontrolled changes and continuous growth in project scope can lead to project delays, cost overruns, reduced quality, and may even jeopardize the entire project.
How can a project manager prevent a scope change from becoming scope creep?
To prevent scope creep, a project manager needs to rigorously monitor and control project scope, ensure all changes go through the change management process, communicate regularly with stakeholders, and strictly adhere to the project scope statement.
What is the scope baseline and why is it important in evaluating scope changes?
The scope baseline is the approved version of a scope statement, Work Breakdown Structure (WBS), and its associated WBS Dictionary. Any proposed change to the scope baseline should go through the formal change control process. It is essential in evaluating scope changes because it serves as a benchmark against which actual results can be measured.
Can scope changes be completely avoided in a project?
It’s nearly impossible to avoid scope changes entirely in a project as they often result from unforeseen circumstances, new requirements, or stakeholder feedback. However, through strict adherence to the project scope and change management processes, uncontrolled changes can be minimized or avoided.
How can technology assist in managing and evaluating scope changes in a project?
Project management software and tools can help manage and evaluate scope changes. They can facilitate the documentation, tracking, and communication of changes, along with helping to analyze the potential impacts of changes on the project.
What is the function of a scope change log?
A scope change log records all requested changes to the project scope and their status. It tracks the documentation, analysis, decision, and implementation of these changes. It’s an important tool for maintaining transparency and managing scope changes effectively.
