In today’s competitive business environment, organizations often turn to performance rankings, stack rankings, or forced distribution methods to drive higher output from their teams. These controversial HR practices rate employees against each other, rewarding the “top performers” and penalizing or even terminating those who fall at the bottom. On the surface, this may appear to be a fair and merit-based approach. However, Dr. W. Edwards Deming’s Red Bead Experiment provides compelling evidence that these practices are deeply flawed and can actually harm organizational performance.

The Pitfall of Performance Rankings

Performance ranking systems, sometimes referred to as “rank and yank,” gained popularity in the late twentieth century and can still be found in organizations worldwide. The basic idea is to compare employees, often pitting team members against one another, and to allocate rewards and consequences based on their relative standing.

The intent behind this approach is straightforward: eliminate the lowest performers, keep employees “hungry” for results, and incentivize excellence. However, what these systems fail to recognize is the profound impact of variation inherent in any work process. This is exactly what Deming’s Red Bead Experiment dramatizes.

The Red Bead Experiment: A Lesson in Randomness

At the heart of the Red Bead Experiment is a simple but powerful demonstration: six workers are asked to produce results by extracting beads from a paddle, with 20% of the beads representing defects (red beads) mixed randomly among 80% “good” white beads. The goal is ostensibly to minimize the number of red beads pulled on each turn.

Despite following identical instructions and similar degrees of effort, each worker’s results fluctuate. Some have high defect rates; others perform closer to the average. The managers (instructors) running the experiment, try all the usual levers: encouragement, threats, targets, slogans, and, crucially, performance ratings. Despite these interventions, the results remain stubbornly unaffected—the variation remains, driven by the system, not individual performance.

When this experiment is run, it quickly becomes clear that the workers have virtually no control over how many red beads they draw. The system is designed so that success or failure is dictated by chance, not skill or effort. And yet, workers are still ranked, praised, blamed, and in some versions even terminated for poor results.

Translating Red Beads to Real-World HR Practices

In many organizations, performance ranking systems ignore the fundamental lesson of the Red Bead Experiment: much of what is measured and rewarded in employee performance is determined by system factors outside the worker’s control.

Just as with the bead sampling, the variance in performance among team members is often a byproduct of process design, workload distribution, available tools, and other systemic influences. When management uses rankings to incentivize or discipline employees, they’re mistaking noise for signal, and randomness for merit.

The Demoralizing Effects of Forced Rankings

Subjecting employees to forced ranking systems can have several damaging side effects, including:

• Undermining Teamwork: Ranking individuals against each other sets up adversarial relationships, reducing information sharing and collaboration.
• Driving Out Talent: High performers who land at the bottom of a distribution due to randomness or poor system design may become demotivated and leave.
• Stifling Innovation: In a climate of fear, where performance appraisals determine job security, employees are less likely to experiment or suggest improvements.
• Encouraging Short-Termism: Employees focus on boosting performance metrics—sometimes at the cost of long-term organizational health—to avoid negative rankings.
• Ignoring the System: Management spends more time appraising individuals than addressing root causes in business processes.

What the Red Bead Experiment Reveals About Rankings

Deming’s Red Bead Experiment provides visual, statistical, and emotional evidence that performance rankings are, at best, misguided when applied to outputs dominated by system variation. By focusing on the worker, we lose sight of where improvement is truly possible: the system itself.

During the exercise, workers who were recognized as “top performers” often receive praise and bonuses, while the “lowest performers” face criticism or even symbolic termination. However, when the process is repeated, performance rankings shift—showing that last round’s “winner” may become the “loser” by chance alone. If this sounds familiar to annual employee review processes, it’s because many workplace systems function in an analogous way.

Alternatives to Performance Rankings: Systemic Process Improvement

So, what is the alternative? Deming’s philosophy—and the evidence from the Red Bead Experiment—strongly suggests that process improvement, not individual evaluation, should be the priority:

• Focus on the System: Management should analyze and improve the workflow, tools, training, and resources to reduce variation and defects.
• Promote Collaboration: Reward teams based on systemic improvement, not competition between members.
• Eliminate Fear: Create a trust-based environment, where employees feel safe to propose changes and surface issues within the process.
• Empower Problem-Solving: Provide data openly and encourage employees to participate in designing better processes.

Conclusion

The Red Bead Experiment is a striking analogy for the pitfalls of performance rankings and other HR tactics that fail to consider the impact of system variation. Rather than boosting productivity, these systems foster fear, erode teamwork, and ignore the potential for genuine continuous improvement. Deming’s work—and the legacy of the Red Beads—teaches us that sustainable quality and performance gains are achieved not through ranking and competition, but by managing and improving the system as a whole.
