One concept that is consistently overlooked by many Program Managers is the difference between Critical Success Factors (CSFs), Performance Measurement Criteria, and Key Performance Indicators (KPIs).
Many professionals use these terms interchangeably because they appear closely related. However, they serve three completely different purposes.
Understanding this distinction isn’t just important for passing the PgMP examination. More importantly, it helps Program Managers build an effective performance management framework that enables better governance, informed decision-making, and successful benefits realization.
Let’s understand this through a simple marathon example.
Imagine you’re preparing to run a marathon.
Your objective is straightforward.
Successfully complete the marathon.
Now ask yourself three simple questions.
Question 1
What must go right for me to succeed?
Some of the Critical Success Factors (CSFs) could be:
- Consistent adherence to the training plan.
- Proper nutrition and hydration throughout the preparation period.
- Adequate sleep and recovery throughout training.
- Remaining injury-free until race day.
- Maintaining discipline and motivation throughout the journey.
Notice something important.
These are not measurements.
They are the conditions and practices that significantly increase the probability of success.
These are your Critical Success Factors (CSFs).
Question 2
What aspects of my preparation and performance should I evaluate?
Now you’re no longer asking what must go right.
Instead, you’re asking what areas should be evaluated to understand whether you’re progressing toward your objective.
Some Performance Measurement Criteria could be:
- Training adherence
- Physical fitness
- Endurance
- Running speed
- Physiological recovery
Notice that these are still not measurements.
They are the dimensions in which performance will be evaluated.
These become your Performance Measurement Criteria.
Question 3
How will I objectively measure these areas?
Now it’s time to define the Key Performance Indicators (KPIs).
| Performance Measurement Criterion | Key Performance Indicator (KPI) |
|---|---|
| Training Adherence | Complete at least 95% of scheduled training sessions |
| Physical Fitness | Resting heart rate remains within the target range |
| Endurance | Complete a continuous 30 km training run before race day |
| Running Speed | Complete a 5 km run in under 25 minutes |
| Physiological Recovery | Heart rate returns to the target recovery zone within the expected time after a long run |
Now you’re measuring performance objectively.

Why This Matters in Program Management
Many organizations begin by defining KPIs.
They immediately start measuring schedule variance, cost variance, resource utilization, productivity, or dozens of other metrics.
But here’s the problem.
If the Critical Success Factors haven’t been identified first, teams often end up measuring activities that have very little influence on the overall success of the program.
Similarly, if Performance Measurement Criteria haven’t been clearly defined, KPIs become isolated numbers that provide little insight into the actual health of the program.
An experienced Program Manager follows a much more logical sequence.
First, identify what must go right.
Then determine what aspects of the program should be evaluated.
Only then define the measurable indicators that objectively demonstrate performance.
This creates a performance management framework that supports better governance, timely corrective actions, informed decision-making, and ultimately, successful benefits realization.
Frequently Asked Questions
Even after understanding the relationship between Critical Success Factors, Performance Measurement Criteria, and Key Performance Indicators, a few practical questions often arise. These are some of the most common questions I receive from Program Managers and PgMP aspirants during mentoring sessions.
1. Can one Critical Success Factor have multiple KPIs?
Yes, and in many cases, it should.
A single Critical Success Factor often needs to be evaluated from multiple perspectives.
For example:
Critical Success Factor
Maintain excellent physical fitness.
Performance Measurement Criteria
Physical fitness.
Possible KPIs
- Resting heart rate within the target range.
- Body fat percentage within the desired range.
- VO₂ Max above the target level.
One success factor may therefore be supported by several KPIs that collectively provide a more complete picture of performance.
2. What is the biggest mistake organizations make while defining KPIs?
The biggest mistake is measuring everything instead of measuring what matters.
More KPIs do not necessarily improve performance.
In fact, too many KPIs often create confusion, dilute management attention, and make decision-making more difficult.
An experienced Program Manager identifies the few measures that best indicate whether the program is progressing toward its intended strategic outcomes.
3. Can Critical Success Factors, Performance Measurement Criteria, and KPIs change during the program lifecycle?
Absolutely.
Programs operate in dynamic environments. Strategic priorities, market conditions, regulations, stakeholder expectations, and organizational objectives may evolve over time.
When significant changes occur, the Program Manager should reassess:
- Whether the existing Critical Success Factors are still relevant.
- Whether the Performance Measurement Criteria continue to reflect the areas that matter most.
- Whether the KPIs still provide meaningful insights into program performance.
Performance management is not a one-time planning activity. It is continuously reviewed and refined to ensure the program remains aligned with organizational strategy and continues to deliver the intended business benefits.
4. Should every constituent project have the same KPIs?
Not necessarily.
Each constituent project may have its own project-specific KPIs based on its scope, objectives, and deliverables. However, the Program Manager should establish standard program-level measurement criteria so that performance can be evaluated consistently across all constituent projects.
Think of it this way:
- Project KPIs measure whether an individual project is successful.
- Program KPIs measure whether the combined outcomes of all projects are achieving the program’s strategic objectives and expected business benefits.
This distinction is particularly important for the PgMP exam because PMI expects Program Managers to think beyond individual project performance.
