Unit 6: Job Analysis and Job Design

Job analysis is the systematic study of a job to identify what work is done, how it is done, and the human attributes needed to do it. Its two direct outputs are the job description (tasks, duties, responsibilities) and the job specification (knowledge, skills, abilities, and other traits). Job design then arranges those tasks into roles that are efficient and motivating. Every downstream HR function depends on this foundation.

Defining properties and conventions:

• Unit of analysis: the job (a group of positions with similar duties), not the individual employee holding it.
• Two outputs: job description (about the work) and job specification (about the worker).
• Job elements hierarchy: micro-motion → element → task → duty → position → job → occupation.
• KSAO framework: Knowledge, Skills, Abilities, and Other characteristics form the specification.
• Uses: recruitment, selection, training design, performance appraisal, job evaluation, compensation, and legal defensibility.
• Job design contrast: analysis describes what is; design prescribes what should be.

II. Methods of Collecting Job Data

The techniques used to gather task and worker-requirement information, each trading off cost, accuracy, and coverage.

A. Observation

Watching the incumbent perform the job in real time and recording activities.

• Best fit: short-cycle, repetitive, observable manual work — assembly line, machine operation.
• Recording tools: activity logs, time-and-motion study, work sampling at fixed intervals.
• Limitation: fails for mental or intermittent work (a design engineer's thinking is invisible); risk of the Hawthorne effect, where being watched alters behaviour.

B. Interview

Structured questioning of the incumbent, the supervisor, or both about duties.

• Types: individual interview, group interview (several incumbents), and supervisor interview for verification.
• Strength: captures mental tasks and infrequent duties observation misses.
• Limitation: incumbents may inflate duties to justify higher pay or status, distorting data.

C. Questionnaire

A standardised written form completed by many jobholders at once.

• Strength: cheapest way to cover large numbers quickly; yields quantifiable, comparable data.
• Structured instrument example: the Position Analysis Questionnaire (PAQ) — 194 items grouped into six divisions (information input, mental processes, work output, relationships, job context, other).
• Limitation: ambiguous items get misread; low literacy or careless responses reduce reliability.

D. Diary or Log Method

The incumbent records each activity and its duration as the day proceeds.

• Strength: captures the full range and rhythm of duties over time, useful for managerial jobs.
• Limitation: relies on discipline and honesty; entries are often incomplete or written retrospectively.

E. Technical Conference and Critical Incident

Two specialist supplements for expert or behaviour-focused jobs.

1. Technical conference: subject-matter experts pool judgement about a job's content; fast, but reflects expert opinion rather than the actual incumbent.
2. Critical incident technique: collectors record specific instances of especially effective or ineffective behaviour; excellent for building appraisal criteria, but time-consuming and skewed toward extremes rather than routine duties.

III. Potential Problems with Job Analysis

Sources of bias and error that erode the accuracy of collected job data.

A. Lack of Top-Management Support

Analysis fails when leadership treats it as a low-priority chore.

• Effect: employees see no reason to cooperate; the study stalls or produces superficial data.
• Concrete signal: no budget, no communicated purpose, so incumbents suspect a hidden downsizing agenda.

B. Single Method / Single Source Reliance

Depending on one technique or one respondent narrows the picture.

• Effect: observation alone misses mental work; one incumbent's view may be idiosyncratic.
• Remedy anchor: triangulate — combine questionnaire plus interview plus supervisor verification.

C. Distortion by the Respondent

Incumbents and supervisors have incentives to misreport.

• Inflation: exaggerating duties to raise the job's evaluated worth and pay grade.
• Fear: understating or hiding tasks when workers suspect the data feeds job cuts.

D. Failure to Update (Static Data)

Jobs drift as technology and structure change, but records lag.

• Effect: a job description written before automation lists obsolete duties, misdirecting hiring and training.
• Anchor: roles reshaped by new software need re-analysis within the review cycle, not once a decade.

E. Activities-Only Focus

Recording tasks while ignoring the worker attributes needed to do them.

• Effect: a complete job description with a missing or vague job specification, weakening selection.
• Correction: every task listed should map to a required knowledge, skill, or ability.

IV. Process of Job Analysis

The sequence of steps that converts raw workplace observation into usable descriptions and specifications.

A. Determining the Purpose and Scope

Analysis begins by fixing why the data is needed, because the use shapes the method.

• Purpose examples: recruitment demands task lists; compensation demands comparable, weightable data.
• Scope decision: which jobs, how many positions, and the depth of detail required.

B. Selecting Jobs and Gathering Background Information

Choosing representative jobs and reviewing what already exists.

• Selection: sample benchmark or high-volume jobs rather than analysing every position.
• Existing sources: organisation charts, prior job descriptions, process flowcharts, and workflow diagrams orient the analyst before fieldwork.

C. Collecting Job-Analysis Data

Applying the methods of Section II to capture tasks and requirements.

• Data collected: work activities, tools and equipment, work context, performance standards, and human requirements.
• Practice: pair a primary method (questionnaire) with a confirming one (interview) to offset single-source bias.

D. Reviewing and Verifying the Data

Confirming accuracy with those who know the job.

• Verification loop: show the draft to the incumbent and the supervisor for correction and endorsement.
• Benefit: verification both improves accuracy and secures buy-in, easing later acceptance of the description.

E. Developing Job Description and Job Specification

Turning verified data into the two formal documents.

• Job description contents: job title, identification, summary, duties, working conditions, reporting relationships.
• Job specification contents: required education, experience, skills, physical demands, and personal traits (the KSAOs).

F. Reviewing and Updating Periodically

Keeping outputs current as work evolves.

• Trigger events: reorganisation, new technology, or role redesign prompt re-analysis.
• Anchor: a scheduled review cycle prevents the static-data problem of Section III.

V. Job Design and its Approaches

Structuring the content, methods, and relationships of a job to serve both organisational efficiency and employee motivation.

A. Meaning and Core Considerations

Job design decides what tasks a job contains, how they are performed, and how the role fits others.

• Three inputs: organisational requirements (efficiency, output), employee needs (variety, autonomy), and environmental factors (workforce skills, expectations).
• Goal tension: engineering efficiency pulls toward simple narrow jobs; motivation pulls toward enriched broad jobs.

B. Job Rotation

Moving employees between different jobs at the same level on a schedule.

• Principle: combats boredom by varying tasks without changing their complexity.
• Benefits: builds a multi-skilled, flexible workforce; eases cover for absence.
• Limitation: the jobs remain routine, so relief is temporary once every rotation is learned.

C. Job Enlargement

Adding more tasks of the same level to a single job — horizontal loading.

• Principle: widens task variety by combining fragmented duties into one larger job.
• Example: a mailroom worker who only sorts now also stamps, logs, and distributes.
• Limitation: more work at the same difficulty can feel like added load without added meaning.

D. Job Enrichment

Adding planning, decision, and control responsibility — vertical loading.

• Basis: grounded in Herzberg's two-factor theory, adding motivators (responsibility, recognition, achievement) rather than hygiene factors.
• Mechanics: give the worker authority over scheduling, quality checks, and methods, not just execution.
• Contrast with enlargement:
  1. Enlargement: horizontal — more tasks, same authority.
  2. Enrichment: vertical — deeper authority and self-management.
• Limitation: not all employees want added responsibility; some prefer predictable routine.

E. The Job Characteristics Model (Hackman and Oldham)

A framework specifying which job dimensions produce motivation.

• Five core dimensions: skill variety, task identity, task significance, autonomy, and feedback.
• Critical psychological states: experienced meaningfulness, experienced responsibility, and knowledge of results.
• Motivating Potential Score:

MPS = [(Skill Variety + Task Identity + Task Significance) / 3]
      × Autonomy × Feedback

• Symbols: each dimension is a survey score; autonomy and feedback multiply, so a zero on either collapses MPS toward zero.
• Moderator: effects are strongest for employees high in growth-need strength.

F. The Engineering (Scientific Management) Approach

Designing jobs for maximum mechanical efficiency, after F.W. Taylor.

• Principle: break work into simple, standardised, specialised tasks timed for the one best method.
• Strength: high productivity, easy training, low skill cost.
• Limitation: extreme specialisation breeds monotony, absenteeism, and turnover — the very problems enrichment addresses.

G. The Socio-Technical Systems Approach

Designing jobs so the social and technical subsystems are jointly optimised.

• Principle: neither technology nor people should be optimised alone; fit them together.
• Application: autonomous (self-managed) work teams given a whole task and control over how they complete it.
• Benefit: balances efficiency with the autonomy and meaningfulness the motivational approaches seek.
