Job Evaluation Tools & Salary Grading:
Choosing the Right Method for Fair Pay

A practical guide to comparing jobs, designing grades, interpreting market data, and turning compensation decisions into a consistent business system.

Job Evaluation Salary Grading Internal Equity Market Pricing HR Governance

By Perinvo Consulting · Practical guidance for HR, Finance and business leaders

Job evaluation and salary grading are not administrative exercises. They help organizations make consistent choices about job levels, career paths, recruitment offers and compensation budgets. Without a common framework, salary decisions may be driven by job titles, negotiation pressure or the urgency of a vacancy rather than the value of the role.

This guide compares four traditional job evaluation methods, three widely known commercial frameworks and four approaches to salary grading. It also includes a practical manufacturing example, a selection matrix, common implementation risks and a 90-day rollout plan.

01. Three different decisions: evaluation, grading and pricing

The sequence matters. A salary survey can show what similar jobs earn elsewhere, but it cannot establish whether the jobs inside your company have been placed at appropriate relative levels. Equally, job evaluation does not automatically determine a salary. Good reward design connects both internal and external evidence.

02. The four main job evaluation methods

The reference guide covers four common approaches. They differ in speed, complexity, transparency and the level of evidence needed. None is automatically the best for every organization.

Why Point Factor is often a practical starting point

A point-factor framework creates a common language for comparing different jobs. For example, a production technician and an HR analyst may have different tasks, but both can be assessed using approved factors such as knowledge, problem solving, accountability and working conditions. The exact factors and weights should reflect the organization’s work and be reviewed for bias.

03. Commercial frameworks: Mercer IPE, Korn Ferry Hay and WTW GGS

The source document also identifies three widely used frameworks. These are not interchangeable templates: each has its own definitions, scoring logic and implementation requirements. Confirm licensing, current documentation and the appropriate evaluator training before applying a proprietary system.

04. Four ways to design salary grades

Once jobs have been evaluated, salary grading brings the results into a manageable structure. The original reference lists four common options, each suited to a different operating model.

05. Worked example: from evaluation points to salary grades

Consider a hypothetical manufacturing company introducing a custom 1,000-point internal job evaluation scale. The company decides the factor weights before evaluating jobs. The numbers below are training examples only and are not actual salaries, market benchmarks, or scores from any proprietary scheme.

The company might then place the evaluated roles into grade intervals. It should review jobs close to grade boundaries, evaluate consistency between job families, and use external salary data only after the internal structure is validated.

What if the market pays more?

If the evaluated role belongs to G5 internally but qualified candidates command more in the external market, the organization should not simply increase the evaluation points. It should check job matching, market data quality, salary-range policy and affordability. Where needed, approve a documented market premium or adjust the range according to policy rather than changing job value to justify pay.

06. Which method fits which organization?

The source gives useful starting recommendations. The table below translates them into business decisions; these are examples rather than universal requirements.

09. Five metrics to test whether the structure works

A strong dashboard shows the exception behind the number. For example, a high proportion of jobs outside salary ranges can reflect outdated pay bands, market pressure, new roles, or legacy decisions. The metric starts the investigation; it does not replace judgment.

10. Mistakes that weaken otherwise good structures

• Evaluating jobholders, not jobs. Personal performance and tenure should not determine the job’s relative size.
• Using a job title as the market match. Check actual accountability, scope and location before benchmarking.
• Choosing weights without validation. Factors should represent real job requirements and avoid unjustified bias.
• Treating grade boundaries as automatic truth. Recheck unusual scores and near-boundary jobs.
• Confusing job grades with salary decisions. External competitiveness, affordability and policy remain separate inputs.
• Ignoring change. Re-evaluate when a role changes materially, not for every normal improvement in performance.
• Publishing salary bands without governance. Set who approves offers, promotions, regrading, exceptions and appeals.

11. Five questions every CEO and HR leader should ask

1. Can we explain why one role has a higher grade than another,using job evidence rather than titles?
2. Are our evaluation factors and grade definitions clear enough for different departments to apply consistently?
3. Which jobs were matched to the market, and how do we know those matches are genuinely comparable?
4. What is the payroll impact of new salary ranges, and who approves exceptions?
5. How will employees request a fair review when the scope of their job changes?
