Job analysis and its methods
Studying what a job involves and what it needs, before hiring, training or paying for it.
Will people work exactly as usual while someone watches them?
Job analysis finds out what a job involves and what kind of person can do it, and feeds almost every other HR decision.
An auto-parts plant in Pune needs twenty new machine operators. Before it can advertise, test candidates or fix their pay, someone has to know exactly what an operator does all day, and what it takes to do it well.
In plain wordsJob analysis is finding out, carefully and on purpose, what a job involves and what kind of person can do it.
Exam definitionA standard textbook definition: job analysis is a systematic study of a job to find the tasks, methods, equipment, skills and attitudes needed for successful performance.
Job analysis yields four kinds of information:
- Purpose and nature: why the job exists and what it involves.
- Organisational fit: its department, reporting line and place in the hierarchy.
- Human profile: the skills, attributes and behaviour it needs.
- Relationships and context: whom the jobholder deals with, what they depend on, the tools they use and the demands they face.
Back to the plant. As an illustration, an analyst watches operators for a week, interviews two supervisors, and collects accounts of the best and worst shifts. She finds that most of an operator's day goes on setting machines, and that the costliest mistakes happen at shift change. That one finding shapes the job advertisement, the selection test and the training plan.
Methods. No single method sees everything, so most analyses combine two or more.
| Method | Key focus | Watch out for |
|---|---|---|
| Direct observation | Watching employees at work; best for routine or physical jobs | It misses thinking work, and people may act differently when watched |
| Work method analysis | Time and motion study to find the most efficient sequence | It suits repetitive manual work; staff may resent being timed |
| Critical incident technique | Analysing exceptionally effective or ineffective incidents | It shows the extremes, not the ordinary day |
| Interview method | Employees and supervisors describe the job in detail | People may make their job sound bigger than it is |
Textbooks also list questionnaires and work diaries, in which jobholders record what they do over a period.
Strategic uses. Job analysis supports work simplification (breaking complex jobs into manageable tasks), sets measurable performance standards, and supports recruitment, selection, training and appraisal.
Don't confuse job analysis with job evaluation. Analysis describes what a job is and what it needs. Evaluation judges what the job is worth compared with other jobs. Analysis comes first and feeds evaluation.
Where it breaks. Jobs change faster than documents. In fast-moving roles, a careful analysis can be out of date within a year. Each method also has a blind spot, as the table shows.
For exams. Expect to match a method to its description. The critical incident technique is linked with John Flanagan (1954); time study with F. W. Taylor; motion study with Frank and Lillian Gilbreth.
A limit of observation: people may behave differently when watched (the Hawthorne effect).
1. Analysing exceptionally effective or ineffective incidents is which method?
Not quite. The answer is “Critical incident technique”. The critical incident technique studies the best and worst cases. Work method analysis is the tempting wrong answer, but it uses time and motion study to find the most efficient sequence.
2. A hospital wants to analyse its doctors' jobs, which involve a lot of diagnosis and judgement. Which method is weakest on its own here?
Not quite. The answer is “Direct observation”. Observation suits routine or physical work and misses thinking work, such as diagnosis. Interviews can be inflated, but they can still capture the reasoning behind the job.
3. An analyst finds that an operator's costliest mistakes happen at shift change. Which use of job analysis does this most directly support?
Not quite. The answer is “Setting performance standards and training for the handover”. Job analysis supports performance standards, training and selection. The other options have nothing to do with what the job involves.

- Job analysis: a systematic study of a job's tasks, methods, equipment, skills and attitudes.
- Yields purpose, organisational fit, the human profile, and relationships and context.
- Methods: direct observation, work method analysis, critical incident technique, interviews; most analyses combine several.
- It produces the job description and job specification, and comes before job evaluation.
Study the job before you fill it.
