Forced Distribution Method

Forced Distribution Method: What Most Managers Get Wrong [HR Guide 2025]

Forced distribution method remains a controversial yet persistent performance appraisal system in today’s corporate world. While at least 10% of Fortune 500 companies reportedly use this approach, many don’t publicly acknowledge its implementation. In fact, according to a 2013 survey, approximately 30% of Fortune 500 companies were still using some form of ranking system, often under different names.

This performance evaluation system, also known as forced ranking, gained prominence in the 1980s at General Electric where the bottom 10% of employees were annually removed from the company. The approach typically categorizes workers into three groups: top performers (20%), average performers (70%), and low performers (10%). However, critics argue that forced distribution in performance appraisal creates a competitive rather than collaborative workplace environment, potentially leading to low morale and high turnover. 

Despite these concerns, the average manager spends over 200 hours annually on performance reviews, with companies of about 10,000 employees investing roughly $35 million each year on these evaluations.

In this guide, we’ll explore the fundamentals of the forced ranking method, examine its advantages and disadvantages, uncover what most managers get wrong when implementing it, and provide real-world examples to help you determine if this approach aligns with your organization’s needs.

What is the forced distribution method in performance appraisal?

“Forced distribution helps to eliminate errors that arise due to rating. These errors are normally attributed to leniency and central tendency.” — IvyPanda, Academic resource platform for educational content 

The forced distribution method represents a systematic approach to evaluating employee performance by requiring managers to rank workers against each other instead of against predetermined standards. Fundamentally different from other evaluation systems, this approach mandates that evaluators distribute employees across performance categories based on a [predefined curve].

How it differs from traditional appraisals

Traditional performance appraisals typically evaluate employees against fixed standards or objectives. In contrast, forced distribution (also known as stack ranking) requires comparative evaluation, where employees are ranked relative to their peers. This method was originally developed by Tiffen to eliminate the central tendency problem—managers’ inclination to rate most employees at the higher end of the scale.

Unlike conventional evaluations that might allow multiple employees to receive top ratings, forced distribution limits the number of employees who can be placed in each category. For instance, in a team of 30 employees, a manager might be instructed to categorize exactly 5 as outstanding performers, 20 as average performers, and 5 as poor performers. This predetermined distribution creates a visible differentiation between performance levels, something often lacking in traditional systems.

The 20-70-10 model explained

The most common forced distribution framework follows a 20-70-10 percentage breakdown:

• 20% top performers (“A players”): These employees demonstrate exceptional achievements, exceed targets, and contribute innovatively. They typically receive promotions, bonuses, and development opportunities.
• 70% middle performers (“B players”): The majority fall into this category—employees who meet expectations but don’t particularly stand out. They may receive modest increments or rewards.
• 10% bottom performers (“C players”): These employees consistently underperform compared to their peers and may face performance improvement plans or termination.

This distribution typically follows a bell curve where a small percentage of employees occupy the extremes (exceptional and poor performers), with the majority falling in the middle. Though percentages may vary by organization, the fundamental principle remains the same—forcing evaluators to differentiate performance levels rather than allowing uniform ratings.

Why companies adopted it

Organizations primarily implemented forced distribution to address several performance management challenges. First, the method helps identify and reward top talent who contribute significantly to organizational success. By clearly distinguishing high performers, companies can better allocate resources for development and retention.

Additionally, the system aims to promote accountability by systematically identifying underperformance. General Electric popularized this approach in the 1980s under Jack Welch, who was known for regularly removing low performers—a practice sometimes referred to as “rank and yank”.

Furthermore, many organizations adopted forced distribution to promote a high-performance culture. The knowledge that performance is being closely monitored and compared creates motivation for employees to strive for excellence. The method provides structure for making difficult decisions about promotions, resource allocation, and potential downsizing.

Notably, forced distribution offers organizational benefits beyond performance management. It supports more strategic resource allocation by identifying which employees deserve greater investment. The method simplifies decision-making during restructuring, providing a systematic approach based on relative performance rather than subjective factors.

How the forced ranking method works

Implementing the forced distribution method requires a systematic approach that ensures fair evaluation while maintaining organizational objectives. Unlike other appraisal systems, this method follows a structured process designed to identify performance differences among employees. Let’s examine how organizations put this controversial yet widely used system into practice.

Step 1: Define performance criteria

First and foremost, successful implementation begins with establishing transparent and measurable performance criteria. These criteria serve as benchmarks against which employees will be evaluated. Organizations must develop clear, objective standards aligned with company goals to ensure employees understand expectations.

Some companies, like General Electric, use specific frameworks—such as their “4 Es” system—evaluating employees on energy level, ability to energize others, edge in making tough decisions, and execution efficiency. These criteria must be relevant to different job functions while supporting broader organizational objectives.

The clarity of these standards ensures employees understand how their performance contributes to the organization’s success, making the subsequent comparative evaluation process more transparent, and resulting in improved inclusive employer branding.

Step 2: Evaluate employees comparatively

Subsequently, managers evaluate employees against their peers rather than against fixed standards. This process typically occurs during a specified timeframe—quarterly, annually, or another predetermined period. Throughout this evaluation period, managers should:

• Track employee performance through ongoing reviews
• Gather feedback from multiple sources
• Document specific contributions and achievements
• Observe workplace behaviors and outcomes

This comparative assessment is what distinguishes forced ranking from traditional appraisal methods. Instead of asking “Did this employee meet standards?” managers ask “How does this employee perform relative to others?”

Step 3: Categorize into performance tiers

Following evaluation, employees are sorted into predetermined performance categories. The most common distribution follows the 20-70-10 model popularized by General Electric:

• Top performers (20%): Consistently exceed objectives, demonstrate exceptional skills and initiative
• Average performers (70%): Meet essential requirements reliably but don’t regularly outshine benchmarks
• Underperformers (10%): Struggle to meet basic performance expectations

This categorization is not meant to permanently label employees but rather to create a clear roadmap for improvement and development. Essentially, the system forces managers to differentiate performance levels rather than allowing everyone to receive similar ratings.

Step 4: Communicate outcomes and next steps

The final step involves communicating results and implementing appropriate follow-up actions. Managers must provide clear feedback to employees about their placement and, more importantly, the reasoning behind it.

For top performers, this often means rewards such as bonuses, promotions, and development opportunities. Average performers typically receive guidance on specific improvement areas along with modest increments.

Contrary to popular belief, most organizations don’t immediately terminate employees ranked in the bottom category. Instead, underperformers generally receive:

• Performance improvement plans
• Additional training and support
• Clear expectations for improvement
• Potential reassignment to more suitable roles

Organizations that implement forced ranking effectively understand that the value comes not from merely categorizing employees but from the actions taken following assessment. The ultimate goal is creating a culture of continuous improvement while maintaining a high-performing workforce.

Advantages and disadvantages of forced distribution method

Every performance management system comes with its own set of strengths and limitations, and the forced distribution method is no exception. Organizations must carefully weigh these factors before implementing this controversial approach to employee evaluation.

Advantages: Identifying top talent, streamlining decisions

The forced distribution method offers several significant benefits that explain its continued use despite criticism. Identifying high-potential employees stands as perhaps its greatest strength. By requiring managers to distinguish between performance levels, the system helps organizations recognize and reward top performers who contribute significantly to organizational success. This clear differentiation creates a framework for allocating resources more strategically, including bonuses, promotions, and development opportunities.

Moreover, the method supports better decision-making efficiency during challenging periods. When organizations face restructuring or downsizing, forced ranking provides a systematic approach to making difficult decisions about which employees to retain. This structured framework eliminates the problem of “ratings inflation” that plagues many traditional performance reviews, where managers tend to rate most employees positively.

Forced distribution primarily aims to create a culture of excellence. By rewarding the highest performers, an organization establishes clear standards, encouraging continuous improvement among employees. This approach helps managers identify employees who need development while providing a systematic way to address underperformance. Consequently, the competitive environment fostered by forced ranking may motivate employees to strive for higher performance levels.

Disadvantages: Morale issues, legal risks, bias

Despite its advantages, forced distribution methods face substantial criticism. Employee morale often suffers significantly under this system. Workers who consistently perform well but don’t make it into the top category frequently experience resentment and decreased job satisfaction. The stress induced by constant peer comparison increases the risk of burnout, leading to physical and emotional exhaustion. Additionally, knowing that a certain percentage must fall at the bottom can be profoundly demotivating.

The method creates serious legal vulnerabilities for organizations. When forced rankings have an unequal effect on any group of workers, companies risk discrimination lawsuits. Although not inherently unlawful, implementation without proper validation and bias-prevention measures can lead to legal trouble.

Perhaps most concerning is the potential for bias throughout the process. The subjective nature of rankings makes them vulnerable to managers’ personal preferences or prejudices. Unless structured specifically to focus on bias detection and elimination, calibration processes may actually introduce another layer of subjectivity rather than improve fairness. Research indicates employees whose performance was compared with others considered these evaluations less accurate and fair, regardless of how favorable their own ratings were.

Furthermore, forced distribution fundamentally undermines collaboration and teamwork. The competitive atmosphere encourages employees to focus on outperforming colleagues rather than working together. This can lead to office politics and negative relationships as employees attempt to ensure others appear less favorable by comparison. As one expert notes, “Do you really want to create a culture of competition where employees feel that if one of their colleagues does really well then there’s a good chance that they will be worse off?”

What most managers get wrong about forced distribution

Many organizations struggle with forced distribution not because of the system itself, but due to how managers implement it. Understanding these common pitfalls can help determine whether the method is right for your organization.

Misunderstanding the purpose of the method

Numerous managers view forced distribution merely as a bureaucratic solution to rating inflation, missing its core purpose. Indeed, the system aims to identify top performers, address underperformance, and drive organizational excellence—not simply to fill predetermined categories. The Institute for Corporate Productivity found that companies using forced ranking systems saw a 14% decline in employee engagement scores compared to those using other evaluation methods. This decline often stems from managers disowning the appraisal event, essentially saying, “I was just following the rules.”

Over-reliance on rigid quotas

Perhaps the most fundamental flaw in implementation is the assumption that every team must contain a fixed percentage of high, average, and low performers. In reality, some teams might have no poor performers, while others might have no exceptional ones. Forcing managers to categorize employees to fit quotas creates an artificial distribution that may not reflect actual performance. This rigidity can lead to unfair evaluations, particularly in high-performing teams where even strong contributors must be labeled as “average” or “low.”

Ignoring team dynamics and collaboration

Forced distribution frequently damages team cohesion, yet managers rarely account for this effect. The competitive atmosphere undermines cooperation as employees prioritize personal achievements over collective goals. Obviously, this approach creates tension in work environments, leading to unhealthy competition and office politics. Employees become reluctant to share ideas or support colleagues when they know only a limited number can receive top rankings.

Failing to provide development support for low performers

Crucially, managers often neglect the “what happens after” component. Without proper employee support—including regular feedback and development plans—the system drives away talent rather than fostering improvement. For forced distribution to be effective, organizations must offer clear development paths for lower-ranked employees, including specific coaching to enhance skills and effective contribution to teams.

Forced distribution method examples and real-world use

“A primary cause cited for the decline was Microsoft forcing managers to distribute employee performance ratings in a ratio of 20%, 70% and 10%.” — Talent Strategy Group, HR consulting firm specializing in talent management

Several major corporations have implemented and subsequently modified or abandoned the forced distribution method over the past few decades, providing valuable insights into its practical applications and limitations.

General Electric and the origin of the vitality curve

Jack Welch popularized the forced distribution method at General Electric between 1981-2001, creating what became known as the “vitality curve.” This 20-70-10 system identified top 20% performers, middle 70%, and bottom 10% who would be removed or improved. Under Welch’s leadership, GE experienced significant earnings growth, prompting executives in other industries to adopt similar approaches. Welch defended the practice, stating: “If you want teamwork, you identify it as a value. Then you evaluate and reward people accordingly”. Nevertheless, even GE eventually moved away from its strict implementation after Welch’s departure, placing greater emphasis on team-building.

Microsoft’s experience and eventual abandonment

Microsoft implemented stack ranking in 2011, requiring managers to distribute employees across five performance buckets with predefined sizes (20%, 20%, 40%, 13%, and 7%). This system quickly became problematic. In a Vanity Fair article, former employees revealed that “people responsible for features would openly sabotage other people’s efforts” to avoid low rankings. The six-month review cycle simultaneously forced short-term thinking over innovation. Microsoft HR chief Lisa Brummel announced the abandonment of this practice in November 2013, stating: “No more curve… Managers and leaders will have flexibility to allocate rewards” based on actual performance.

Amazon’s controversial implementation

Amazon continues using a variation called “Organization Level Review,” where managers debate subordinates’ rankings in meetings likened to “getting ready for a court case”. The company targets removing the bottom-performing 6% annually through what they term “unregretted attrition”. Anecdotally, when Amazon briefly paused this process following negative publicity in 2015, “poor performers just didn’t end up leaving the company,” which former executives claim “hurt the company for a couple years”. Coupled with Amazon’s competitive culture, this system has reportedly contributed to high turnover rates and a nickname for employees: “Amholes”.

Lessons from companies that moved away from it

Numerous organizations have abandoned forced distribution methods, including Ford, Goodyear, and Adobe. Primary reasons include discrimination lawsuits, employee engagement declines, and collaboration issues. Research by the Institute for Corporate Productivity found companies using forced ranking systems experienced a 14% decline in employee engagement scores compared to those using alternative methods. Furthermore, companies reported that forced ranking often drives away valuable talent simply to meet quotas, creating what critics call “a very selfish game” where employees prioritize outperforming colleagues over teamwork. Prior to implementation, organizations must carefully consider whether their culture can support such a competitive evaluation system.

Conclusion

After all, the forced distribution method remains one of the most divisive performance appraisal systems in modern business. Though potentially powerful for identifying top talent and creating accountability, this approach undeniably creates significant challenges. Specifically, the competitive environment often undermines teamwork, damages employee morale, and exposes organizations to legal vulnerabilities if not implemented with extreme care.

What becomes evident from examining both theoretical models and real-world applications is that success depends less on the system itself and more on how managers implement it. Companies like Microsoft and General Electric eventually moved away from rigid forced rankings, recognizing that the costs sometimes outweighed the benefits. Meanwhile, organizations that continue using modified versions must constantly balance performance differentiation against potential negative consequences.

The forced distribution method works best when managers understand its true purpose – not simply filling quotas but fostering continuous improvement. Additionally, successful implementation requires robust development support for lower-ranked employees, transparent communication about criteria, and careful consideration of team dynamics.

Before implementing any performance ranking system, organizations should honestly assess their culture and goals. Despite its potential advantages, forced distribution fundamentally creates winners and losers, a reality that conflicts with collaborative environments. Alternatively, companies might consider hybrid approaches that maintain performance differentiation without rigid quotas.

Ultimately, effective performance management transcends any single methodology. The most successful organizations focus less on forcing distributions and more on developing managers who can provide meaningful feedback, recognize excellence, address underperformance, and build high-functioning teams regardless of the evaluation system they use.
