Job characteristics model: the 5 core dimensions, MPS and examples

Only 20% of employees worldwide were engaged in 2025, down from 23% in 2022, Gallup's State of the Global Workplace report found. Pay and perks explain part of that gap, but how the job itself is built explains a lot of the rest.

The job characteristics model, developed by J. Richard Hackman and Greg Oldham, explains why some jobs motivate people and others drain them. It says five core job characteristics (skill variety, task identity, task significance, autonomy and feedback) create three psychological states that drive motivation, satisfaction and work quality.

Below, you will see the five dimensions, the motivating potential score formula and worked examples for real roles. You will also learn how to apply the model to one role and use it when hiring.

TL;DR:

• The job characteristics model, from Hackman and Oldham, says five job features drive motivation: skill variety, task identity, task significance, autonomy and feedback.
• These five feed three psychological states: meaningfulness, responsibility for outcomes and knowledge of results. People need all three for strong internal motivation.
• Motivating potential score = the average of skill variety, task identity and task significance, multiplied by autonomy and feedback. Scores run from 1 to 343.
• A low autonomy or feedback rating pulls the whole job down. Raising a contact center agent's autonomy from 2 to 4 doubled the MPS from 40 to 80.
• Apply it to one role at a time: score the five characteristics, fix the weakest, pilot for 30 to 60 days, then measure.
• Autonomy only motivates people with the skills to handle it, so test judgment and job skills before hiring for high-autonomy roles.
• Use the MPS to compare a job before and after a change, not as a pass mark. Simply adding the five ratings often works as well.

What is the job characteristics model?

The job characteristics model (JCM), also called job characteristics theory, is a framework for designing jobs so the work itself motivates people. Hackman and Oldham first set it out in 1975, tested it in 1976 and published the final version in their 1980 book Work Redesign.

The idea came from a practical problem. Factories in the 1960s split jobs into small, simple tasks to make work faster.

Instead, experienced workers got bored, quality dropped and people left. Hackman and Oldham asked a different question: which features of a job make people want to do it well?

Their answer has three layers:

1. Five core job characteristics, the features of the job itself.
2. Three critical psychological states, how the person experiences the work.
3. Personal and work outcomes, such as motivation, satisfaction and work quality.

To measure the characteristics, they built the Job Diagnostic Survey (JDS), a questionnaire that asks jobholders to rate their own role, plus a Job Rating Form that supervisors or outside observers fill in. HR teams still use short versions of both today.

What are the 5 core job characteristics?

The 5 core job characteristics are skill variety, task identity, task significance, autonomy and feedback. Each one describes a feature of the job, not the person, which is why HR and hiring managers can change them through job design.

1. Skill variety

Skill variety is how many different skills and activities a job needs. A support agent who only reads scripts has low skill variety.

One who troubleshoots, writes help articles and trains new hires has high skill variety. More variety keeps work interesting, but piling on unrelated tasks just adds load.

2. Task identity

Task identity is how far a person completes a whole, visible piece of work from start to finish. A claims handler who owns a claim from first report to payout has high task identity.

One who only checks a single form field has low task identity and rarely sees the result.

3. Task significance

Task significance is how much the work affects other people, inside or outside the company. Nurses and air traffic controllers see it every day.

For roles where the impact is less obvious, like payroll or data entry, managers can raise it by showing who depends on the work.

4. Autonomy

Autonomy is the freedom a person has to plan the work and decide how to do it. A developer who chooses the approach within clear guardrails has high autonomy.

An agent whose every call is timed and scripted has very little. Autonomy is what makes people feel the result is theirs.

5. Feedback

Feedback, in this model, means how clearly the job itself shows people how well they are doing. A salesperson sees deals close.

A back-office analyst may wait months to hear anything. Dashboards, quality scores and customer comments all add feedback from the work, alongside feedback from managers.

What are the three critical psychological states?

The three critical psychological states are experienced meaningfulness, experienced responsibility for outcomes and knowledge of results. Each core characteristic feeds one state, and the model says people need all three to feel strong internal motivation.

• Experienced meaningfulness comes from skill variety, task identity and task significance. People feel the work is worth doing.
• Experienced responsibility for outcomes comes from autonomy. People feel the results depend on their own effort and choices.
• Knowledge of results comes from feedback. People know how well they are doing, so they can improve.

The three states work like links in a chain. A job can feel meaningful, but if nobody ever tells the person how they are doing, motivation still fades.

That is why the model treats feedback and autonomy as so important.

What outcomes does the job characteristics model predict?

The job characteristics model predicts four main outcomes when all three psychological states are present: high internal work motivation, high satisfaction with growth, high general job satisfaction and better work effectiveness, meaning both quality and quantity of work.

The 1975 version also listed lower absenteeism and turnover. Hackman and Oldham dropped those from the 1980 version.

Pay, the manager and the job market also shape whether people stay, so job design alone cannot explain it. In practice, most HR teams still track retention alongside the four core outcomes.

How do you calculate the motivating potential score?

The motivating potential score (MPS) combines the five characteristics into one number that shows how motivating a job is likely to be. Each characteristic is rated, usually on a 1 to 7 scale, and then put into this formula:

MPS = ((skill variety + task identity + task significance) / 3) x autonomy x feedback

Scores run from 1 to 343. The three meaningfulness characteristics are averaged, so a low score on one can be balanced by the others.

Autonomy and feedback multiply the result, so a low score on either one pulls the whole job down.

Here is a worked example for a contact center agent:

1. Skill variety 4, task identity 3, task significance 5. The average is (4 + 3 + 5) / 3 = 4.
2. Autonomy is 2 and feedback is 5.
3. MPS = 4 x 2 x 5 = 40.

Now give the agent the power to issue refunds up to a set limit and close cases without a supervisor. Autonomy rises to 4 and the MPS doubles to 80, without adding a single new task.

Pro tip: Use MPS to compare the same job before and after a change, or to compare similar roles, not to label a job as "good" or "bad". The ratings come from people's views, so collect them from the jobholder, the manager and a peer, then compare.

What decides whether the model works for a person?

Whether the job characteristics model works for a person depends on three moderators that Hackman and Oldham added to the model. The same enriched job can energize one employee and stress another.

• Growth need strength: Some people want challenge, learning and responsibility more than others. People with high growth need respond strongly to enriched jobs. People with lower growth need may prefer stable, clear work.
• Knowledge and skill: More autonomy only helps if the person can do the work. Give a new hire full control before they have the skills and the result is stress and mistakes, not motivation.
• Context satisfaction: If pay, job security, workload or the manager are poor, a better-designed job will not fix it. People need the basics in place before job design can help.

For hiring teams, the second moderator matters most. It is a reason to check skills before a role is designed around a lot of autonomy.

What are examples of the job characteristics model?

Examples of the job characteristics model show how one change in job design can lift a low-scoring characteristic. The table below covers four common roles, each with the weak point, the redesign and the characteristic it raises.

The contact center example matters in volume roles like BPO, where turnover is high and the work can feel repetitive. Not every repetitive task can be removed, but autonomy and feedback can almost always be raised.

How do you apply the job characteristics model?

You apply the job characteristics model by picking one role, scoring it, changing the weakest characteristics and measuring the result. Six steps keep the work small enough to test.

1. Pick one role and set goals: Start with a role that has high turnover, low engagement or quality issues. Decide what success looks like: fewer errors, faster cycle time, better retention.
2. Map the tasks: List what the job actually involves, who hands work to whom and where the person loses sight of the result. A job analysis gives you most of this.
3. Score the five characteristics: Run a short survey with 1 to 7 ratings for each characteristic, from jobholders, managers and peers. Work out the MPS.
4. Redesign the weakest points: Match each low score to a lever: cross-training for skill variety, case ownership for task identity, impact stories for task significance, decision rights for autonomy, dashboards and short review cycles for feedback.
5. Pilot for 30 to 60 days: Try one or two changes with a small group before rolling them out.
6. Measure and adjust: Compare the before and after scores, plus the business goals from step 1. Keep what works and change what does not.

Involve employees from step 2 on. They know where the job breaks down, and people accept a redesign they helped shape.

Pair autonomy with clear limits and support, so freedom does not turn into guesswork.

How can hiring teams use the job characteristics model?

Hiring teams can use the job characteristics model to describe roles honestly, decide what to assess and pick candidates who will stay motivated in the job as it really is. Most guides treat the model as a tool for redesigning existing jobs, but it is just as useful before anyone is hired.

Write job descriptions that show the five characteristics: Candidates want to know how much freedom they will have, what they will own and how they will know they are doing well. Spell these out in the job description instead of listing duties alone.

If the role has low autonomy, say so. A realistic job description means fewer early exits.

Assess the skills that autonomy depends on, because autonomy only motivates people who can handle it. For high-autonomy roles, test judgment and job skills before the offer, such as with a situational judgment test or a role-specific skills test.

Testlify's test library has 3,500+ validated tests you can use to assess those skills.

Ask about growth need in interviews: Use the five characteristics as the base for structured interview questions, and score answers the same way for every candidate.

Personality tools can add context here. A Big Five personality test shows traits like openness, which can hint at how much a person will enjoy a varied, self-directed role.

Use it as one input, never as the only reason to hire or reject.

How is AI changing job characteristics?

AI is changing job characteristics by taking over tasks inside many roles, which can raise or lower each of the five dimensions depending on how the job is redesigned. Microsoft's 2025 Work Trend Index found that 46% of leaders say their companies already use AI agents to fully automate workflows or processes, and 83% expect AI to let employees take on more complex, strategic work earlier in their careers.

The job characteristics model gives a simple check for each AI rollout:

• Skill variety can rise if AI removes routine work and people move to harder problems. It falls if people are left only checking AI output all day.
• Task identity is at the most risk. When an agent handles the middle of a process, people may only see the start and the end. Give them ownership of the whole outcome, not just the hand-off.
• Task significance stays high when people handle the cases that matter most, such as complex customers or exceptions.
• Autonomy depends on decision rights. Decide which calls stay with people and which the AI can make alone.
• Feedback can improve a lot, because AI tools produce data on quality and speed. Share it with the people doing the work, not only their managers.

The same report found that 38% of leaders expect their teams to be redesigning business processes with AI within five years. That redesign is a good moment to score roles with the five characteristics, before and after.

What are the benefits of the job characteristics model?

The benefits of the job characteristics model are clearer job design, more motivated employees and better data for managers. Because the model breaks a job into five parts, teams can see exactly what to fix instead of guessing.

• Better job enrichment: The model gives a clear way to add meaning, ownership and feedback to roles. See job enrichment for more on this approach.
• Fairer delegation: Managers can spread work by matching tasks to skills and growth goals, rather than overloading a few people and underusing others.
• Clearer roles: Task identity and task significance push teams to define what each role owns and how it connects to the rest of the business.
• Simpler performance reviews and goal setting: When feedback is built into the job, reviews hold fewer surprises and goals are easier to track.
• A shared language for job design: HR, managers and employees can discuss a role using the same five terms, which makes job design decisions faster.

Engagement is the prize. Well-designed jobs will not solve every cause of stress or disengagement, but they remove one that HR can control.

What are the limitations of the job characteristics model?

The limitations of the job characteristics model come from its age and from how it is measured. The model is still a useful starting point, but HR teams should know where it falls short.

• Ratings come from people's views: Two people in the same job can rate it very differently, depending on mood, manager and team. Combine survey ratings with observation and real performance data.
• MPS is not precise: Later reviews found that simply adding up the five ratings often works as well as the MPS formula. Treat the score as a guide, not a measurement.
• It leaves out the social side of work: Support from colleagues, teamwork and contact with customers matter a lot today, and the original model does not cover them. Later work design models added these social characteristics.
• It ignores workload and context: A highly enriched job with too much work still leads to burnout. Pay, workload and management need attention on their own.
• Not every job can be enriched equally: Safety-critical and regulated roles have limits on autonomy. Focus on the characteristics you can change, often feedback and task significance.

Key takeaway: The job characteristics model works best as a diagnostic tool. Use it to find the weakest part of a role, change that part and measure the result, rather than as a full theory of motivation.

Job characteristics model vs others

The job characteristics model is a framework for analyzing jobs, while job enrichment, enlargement, rotation and crafting are ways to change them. The model tells you which characteristic is weak. The other approaches are tools to fix it.

Enlargement on its own often adds work without adding motivation. Enrichment and crafting usually do more for the three psychological states.

Where should you start with the job characteristics model?

The job characteristics model is best started with one role you already worry about. Score the five characteristics with the people in that role, fix the lowest one and measure what changes over the next two months.

When you hire for the redesigned role, make sure candidates have the skills its autonomy depends on. For more on what keeps people going once they join, read our guide to employee motivation.
