Motivating Potential Score (MPS) Calculator: Job Characteristics Model

How is the Motivating Potential Score calculated?

MPS = [(Skill variety + Task identity + Task significance) / 3] x Autonomy x Feedback. Each dimension is scored 1 to 7 on the Job Diagnostic Survey, so MPS runs from 1 to 343 (or to 125 on a 1-5 scale). Example: SV 5, TI 4, TS 6, autonomy 5, feedback 3 gives (15 / 3) x 5 x 3 = 75. Because autonomy and feedback multiply, either one near the bottom pulls the whole score down.

Many pages say MPS runs from 1 to 125 without saying that is only true on a 1-5 scale; on the Job Diagnostic Survey's 1-7 scale it runs to 343.

Enter the five job dimension scores; the calculator gives the MPS, the additive alternative research has supported, and which dimension to redesign first.

Each score is the mean of that dimension's survey items, with reverse-keyed items flipped. Example scores are filled in.

The model in brief

Hackman and Oldham (1975, 1976) proposed that five core job characteristics create three psychological states (experienced meaningfulness, responsibility for outcomes, and knowledge of results), which lead to internal motivation, satisfaction and performance. Skill variety, task identity and task significance build meaningfulness, so they are averaged; autonomy builds responsibility and feedback builds knowledge of results, so each enters on its own. Growth need strength moderates the effect: people with high growth needs respond more to an enriched job.

Multiply or add?

Fried and Ferris's (1987) meta-analysis found that simply adding the dimensions predicted outcomes as well as or better than the multiplicative MPS. The multiplicative form still matters for teaching and for exams because it captures the model's claim that a job with no autonomy or no feedback cannot be motivating; the calculator shows both.

Before you rely on this

What this will not tell you

The score is only as good as the ratings: use the Job Diagnostic Survey or the Work Design Questionnaire items as published, averaged per dimension. No verified norm for an "average" MPS is quoted here; compare jobs within your own organisation instead. Nothing you type leaves your browser.

Questions

Questions people actually ask

What is a good Motivating Potential Score?

There is no universal cut-off. Compare jobs measured the same way; a job with a much lower MPS than similar jobs is a candidate for redesign, starting with its weakest of autonomy and feedback.

What is the range of MPS?

1 to 343 when each dimension is scored 1 to 7 (the Job Diagnostic Survey scale), and 1 to 125 on a 1 to 5 scale.

Why are autonomy and feedback multiplied?

In the model, autonomy creates a sense of responsibility and feedback creates knowledge of results; without either psychological state, internal motivation should not arise, so a near-zero on either drives MPS toward its minimum.

What are the five core job characteristics?

Skill variety, task identity, task significance, autonomy and feedback from the job.

Who developed the Job Characteristics Model?

J. Richard Hackman and Greg R. Oldham, in the Journal of Applied Psychology (1975) and Organizational Behavior and Human Performance (1976), with the book Work Redesign (1980).
