Monitoring and Control
Monitoring and Control is the continuous process of tracking project execution, measuring actual performance against planned performance, analyzing variances, and taking corrective actions to ensure project objectives are met. It is the “steering wheel” of project management—without it, projects drift off course undetected until failure becomes unavoidable.
The Core Purpose
Monitoring and control answers three fundamental questions:
- Where are we now? (Actual status)
- Where should we be? (Planned status)
- What do we do about the gap? (Corrective action)
Effective monitoring and control enables:
- Early detection of problems before they become crises
- Informed decision-making based on actual data, not guesswork
- Stakeholder confidence through transparent progress reporting
- Risk mitigation by tracking risk indicators and trigger conditions
- Scope discipline by preventing uncontrolled expansion
- Quality assurance by verifying deliverables meet specifications
The Monitoring and Control Cycle
The process follows a continuous loop that operates at multiple levels—daily, weekly, and milestone-based.

Step 1: Establish Baselines
Before monitoring can begin, baselines must be established during project planning:
| Baseline Type | What It Captures | Key Metrics |
|---|---|---|
| Scope baseline | Approved requirements, WBS, deliverables | Requirements count, feature list |
| Schedule baseline | Planned start/finish dates, milestones | Duration, critical path, float |
| Cost baseline | Time-phased budget | Planned value (PV), budget at completion (BAC) |
| Quality baseline | Quality targets, acceptance criteria | Defect density, test coverage, performance targets |
| Risk baseline | Identified risks, probability, impact | Risk exposure, contingency reserves |
Step 2: Measure Actual Performance
Collect data on actual project status using the data collection methods previously discussed. Key measurements include:
- Actual start and finish dates for activities
- Actual effort and cost expended
- Work completed (quantitative and qualitative)
- Defects found and fixed
- Risks that have occurred or changed
- Resource utilization
Step 3: Compare Actual to Plan
Calculate variances to understand the magnitude and direction of deviations.
Schedule variance = Actual progress – Planned progress
Cost variance = Earned value – Actual cost
Scope variance = Completed features vs planned features
Step 4: Analyze Variance
Not all variances require action. Analysis determines root causes and significance.
Questions to answer:
- Is the variance within acceptable thresholds?
- What is the root cause (e.g., poor estimate, skill gap, requirement change)?
- What is the impact on other constraints (scope, schedule, cost, quality)?
- Will the variance self-correct or worsen?
Step 5: Take Corrective Action
Based on analysis, select and implement appropriate responses:
- Minor variance → Adjust daily work, reassign resources
- Moderate variance → Revise schedule, add overtime, reduce scope
- Major variance → Formal change request, baseline revision, escalation
- Critical variance → Project replanning, sponsor notification, possible cancellation
Key Success Factors
- Establish baselines first – You cannot monitor what you never planned
- Automate data collection – Manual monitoring doesn’t scale and decays
- Focus on trends, not snapshots – A single data point rarely tells the full story
- Define thresholds and act on them – Monitoring without action is observation, not control
- Close the feedback loop – Ensure corrective actions are implemented and verified
- Match monitoring granularity to project phase – Detailed early, higher-level late
- Maintain a single source of truth – Avoid conflicting data from multiple tools
- Communicate proactively – Stakeholders should never be surprised by status reports
