Factor Comparison Method: A Hybrid Approach to Job Evaluation

Imagine you’re trying to figure out fair wages for everyone in your organization. You know that a janitor shouldn’t earn the same as a department manager, but how do you systematically determine what each position is truly worth? Enter the Factor Comparison Method-a sophisticated job evaluation technique that not only ranks jobs but also directly assigns monetary values to them. This hybrid approach, developed in the early 20th century, revolutionized how organizations evaluate positions by creating a unique system that compares jobs against carefully selected benchmark positions while simultaneously determining their wage rates.

The birth of a hybrid solution 🔗

In the early 20th century, industrial engineer Eugene Benge was wrestling with the limitations of existing job evaluation methods. He noticed that simple ranking systems were too subjective, while point rating methods, though more systematic, were often disconnected from actual wage-setting processes. His solution? Create a method that would bridge job evaluation and wage determination into one seamless process.

The Factor Comparison Method emerged as an offshoot of point rating systems, but with a crucial twist. Instead of using abstract points, this method uses real money values and compares all jobs against a set of carefully chosen “benchmark” jobs. Think of it as creating a salary ladder where each rung represents actual jobs in your organization, and every other position finds its place by comparing itself to these established benchmarks.

Step 1: Building your foundation with benchmark jobs 🔗

The success of the Factor Comparison Method hinges entirely on selecting the right benchmark jobs. These aren’t just any positions-they’re the cornerstone of your entire evaluation system. But what makes a job worthy of benchmark status?

Clear and comprehensive job descriptions: Your benchmark jobs must have crystal-clear descriptions that leave no room for interpretation. If you can’t clearly define what a job entails, how can you use it as a standard for comparison?

Representative across organizational levels: Your benchmarks should span the entire organizational hierarchy. You might choose a filing clerk, administrative assistant, supervisor, and department head to ensure you have reference points at every level.

Universally accepted wage rates: Perhaps most importantly, everyone involved-management, HR, and employees-must agree that these benchmark jobs are paid appropriately. If there’s controversy about a benchmark job’s current salary, it can’t serve as a reliable standard for others.

Typically, organizations select between 10-20 benchmark jobs, ensuring they cover different departments and job levels. These jobs become your “measuring stick” for everything else.

Step 2: Ranking benchmark jobs by critical factors 🔗

Once you’ve selected your benchmark jobs, a committee (usually comprising HR professionals, supervisors, and sometimes employee representatives) ranks these jobs according to predetermined factors. Common factors include:

Mental requirements (or mental effort): How much thinking, problem-solving, and decision-making does the job require?

Skill requirements: What level of education, training, or experience is necessary?

Physical requirements (or physical effort): How physically demanding is the position?

Responsibility: What level of accountability comes with the role?

Working conditions: Are there any challenging environmental factors?

For example, if you’re ranking a janitor, nurse, and department manager on “mental requirements,” the department manager would likely rank first, the nurse second, and the janitor third. This ranking process happens independently for each factor, creating multiple ranking lists.

Step 3: Breaking down wages into factor values 🔗

Here’s where the Factor Comparison Method gets truly innovative. While the committee is ranking jobs by factors, they also take each benchmark job’s current wage and divide it among the various factors based on how much each factor contributes to the job’s overall value.

Let’s say a supervisor earns $50,000 annually. The committee might allocate this wage as follows:

• Mental requirements: $20,000 (40%)
• Skill requirements: $15,000 (30%)
• Physical requirements: $2,000 (4%)
• Responsibility: $10,000 (20%)
• Working conditions: $3,000 (6%)

This process happens for every benchmark job, creating a monetary value for each factor across all benchmark positions.

Reconciling rankings and finalizing your scale 🔗

Now comes the moment of truth. You have two sets of rankings: one based on factor importance and another based on monetary allocation. These should align perfectly, but they rarely do initially.

If a job ranks second in “skill requirements” but the monetary allocation suggests it should rank fourth, there’s a discrepancy that needs resolution. The committee must either adjust the money values or re-examine the job content to understand why the rankings don’t match.

Jobs that consistently show irreconcilable differences are eliminated from the benchmark set. This quality control process ensures that your final benchmark scale is rock-solid and internally consistent.

Evaluating all other positions 🔗

With your validated benchmark scale in place, evaluating non-benchmark jobs becomes systematic and straightforward. For each position you’re evaluating, you compare it factor-by-factor to your benchmark jobs.

Let’s say you’re evaluating a new “Marketing Coordinator” position:

Mental requirements: Comparing to your benchmarks, this job requires more mental effort than a filing clerk but less than a department manager. It aligns closely with your administrative supervisor benchmark, so it receives that monetary value.

Skill requirements: The position requires specialized marketing knowledge, placing it between your administrative assistant and marketing manager benchmarks. You might interpolate the value or choose the closer match.

This process continues for each factor. The final wage for the Marketing Coordinator is simply the sum of all factor values assigned through these comparisons.

Advantages that make this method shine 🔗

The Factor Comparison Method offers several compelling advantages that have kept it relevant for nearly a century:

Systematic yet flexible: Unlike simple ranking methods, it provides a structured approach while allowing for nuanced comparisons between positions.

Tailor-made for your organization: Because it uses your actual jobs as benchmarks, the system is specifically designed for your organizational context, not borrowed from generic industry standards.

Direct wage determination: There’s no need for separate salary surveys or complex conversion formulas-wages are built directly into the evaluation process.

Comprehensive factor analysis: By breaking jobs down into multiple factors, it ensures that all aspects of a position are considered in the evaluation.

Detailed and objective analysis: This method provides a thorough analysis of jobs by breaking them down into specific factors, allowing for more objective comparisons between positions.

Challenges and limitations to consider 🔗

Despite its sophistication, the Factor Comparison Method isn’t without drawbacks:

Complexity in application: The method is complex and can be very time-consuming, especially for large organizations with many job roles to evaluate. It requires significant training and expertise to implement correctly.

Difficult to explain: Try explaining to an employee why their job ranks where it does using factor comparisons and monetary allocations. It’s not exactly water cooler conversation.

Requires expertise: This method requires a high level of expertise to identify and weigh the factors correctly. Inaccurate weighting or factor selection can lead to skewed results.

Subjectivity in factor selection: Although it aims to be objective, the selection of factors and the assignment of weights can introduce subjectivity into the process, which might affect the fairness of the results.

Benchmark dependency: The entire system is only as good as your benchmark jobs. If these become outdated or if key benchmarks are eliminated, the whole system may need rebuilding. Maintaining consistency over time can be challenging as job roles and organizational priorities change.

Expensive to implement: The complexity and need for expertise make this method more expensive to implement compared to simpler job evaluation methods.

Is the factor comparison method right for your organization? 🔗

The Factor Comparison Method works best in stable organizations with well-defined job structures and a commitment to a systematic approach to compensation. It’s particularly valuable when you need to evaluate many similar positions or when you want your evaluation system closely tied to actual wage-setting.

However, it might not be suitable for rapidly changing organizations, small companies without diverse job levels, or situations where simplicity and ease of explanation are prioritized over systematic precision. Research has shown that companies achieving pay equity through proper job evaluation are more likely to attract the right talent, meet financial goals, and effectively practice innovation.

What do you think? Given the complexity of implementing the Factor Comparison Method, do you believe the benefits of having wages directly integrated into job evaluation outweigh the challenges of managing such a sophisticated system? How might modern technology help address some of the traditional limitations of this method?
