6 Human Resource Planning and Job Analysis: HRP Process, Forecasting Methods, Job Description and Specification, KSAOs, and Job Design (Rotation, Enlargement, Enrichment and the Hackman-Oldham Model)
6.1 Two Sister Processes
This chapter covers two closely linked HR processes that feed each other. Human Resource Planning (HRP) answers the question “how many people of what kind do we need, and when?” Job Analysis answers the prior question “what does each of these jobs actually involve, and what kind of person can do it?” You cannot plan headcount without knowing what each job demands; you cannot specify a job without a sense of where it fits in the workforce plan.
6.2 A · Human Resource Planning
6.2.1 What is HRP?
Human Resource Planning (HRP) — also called manpower planning in older texts — is the process of forecasting an organisation’s future demand for and supply of the right type of people in the right number, and matching the two through deliberate action.
| Author | Definition | Foregrounds |
|---|---|---|
| Eric Vetter | “The process by which management determines how the organisation should move from its current manpower position to its desired manpower position” | Movement from “as-is” to “to-be” |
| James W. Walker | “Estimating the demand for human resources, identifying the sources of supply, and developing strategies to match demand and supply” | Three-step demand-supply-strategy spine |
6.2.2 Nature and Features of HRP
- Future-oriented — always about a horizon (short, intermediate, long).
- Goal-oriented — derived from the firm’s strategy.
- System-oriented — links recruitment, training, succession, compensation and separation.
- Continuous — rolled forward as assumptions change.
- Quantitative and qualitative — counts heads and assesses skill mix, attitude, culture fit.
- Time-bound — every demand and every supply estimate is anchored to a date.
6.2.3 Six Reasons HRP is Strategic
- Reduces uncertainty — replaces panic with planning.
- Avoids surprises — both shortages and surpluses are expensive.
- Enables training and development — a multi-year skill-gap forecast is the single best input to a training plan.
- Supports succession — who replaces the plant manager when she retires in three years?
- Controls labour cost — people are typically the largest single line item.
- Aligns HR with strategy — a diversification or new technology demands a different workforce.
6.2.4 The Five-Step HRP Process
| # | Step | What it produces |
|---|---|---|
| 1 | Analyse organisational objectives | Linkage between business strategy and HR plan |
| 2 | Forecast demand for HR | Number and type of people the firm will need |
| 3 | Forecast supply of HR (internal + external) | Number and type likely to be available |
| 4 | Identify the gap (demand − supply) | Surplus or shortage by category |
| 5 | Action plan | Recruitment, training, redeployment, retention, redundancy |
6.2.5 Methods of Demand Forecasting
| Method | What it does | Useful when |
|---|---|---|
| Managerial judgement | Line managers estimate people they will need | Stable environments, small firms |
| Ratio-trend analysis | Past ratios (1 supervisor : 10 operators) projected forward | Steady production technology |
| Work-study technique | Time-and-motion data → man-hour requirements | Repetitive, measurable work |
| Regression analysis | Statistical relationship between business variable and headcount | Sufficient historical data |
| Delphi technique | Iterative anonymous expert estimates converging to consensus | Long horizon, high uncertainty |
| Workforce analytics / AI | Algorithms over operational data | Large firms with HRIS in place |
6.2.6 Methods of Supply Forecasting
| Method | What it does |
|---|---|
| Skill inventory | Database of current employees’ skills, qualifications, experience |
| Replacement chart | Visual map of who replaces whom on the organisation chart |
| Succession plan | Multi-year pipeline for critical positions |
| Markov analysis | Probabilistic transitions between job categories over time |
| External labour market scan | Demographics, education output, competitor poaching |
- Delphi = iterative, anonymous, written, expert estimates converging to consensus. (Demand forecasting.)
- Brainstorming = open, face-to-face group idea generation. (Different technique.)
NTA exploits this — Delphi is anonymous and iterative; brainstorming is open and one-round.
6.2.7 Barriers to Effective HRP
- HR plans dissociated from business strategy — the most damaging.
- Conflict between line and HR.
- Inadequate information systems.
- Resistance from employees and unions.
- Inertia — last year’s headcount becomes this year’s plan by default.
- Volatile environments in which forecasts age within months.
6.3 B · Job Analysis
6.3.1 What is Job Analysis?
Job analysis is the process of collecting, examining and recording information about the contents of a job and the human attributes needed to perform it. Its two outputs are the job description (statement of duties) and the job specification (statement of qualifications).
| Element | Concerned with | Output |
|---|---|---|
| Job description | The job itself | Duties, responsibilities, working conditions, reporting lines |
| Job specification (Person specification) | The person to do the job | Qualifications, experience, skills, abilities, personal traits |
6.3.2 Six-Step Process of Job Analysis
| # | Step | What it produces |
|---|---|---|
| 1 | Determine the use | Selection? Training? Compensation? Each needs different detail |
| 2 | Review background | Existing chart, process flow, prior job descriptions |
| 3 | Select representative jobs | A sample where total coverage is impractical |
| 4 | Collect job analysis data | Using the methods below |
| 5 | Verify with the job-holder and supervisor | Reduces bias and error |
| 6 | Develop job description and specification | The two final documents |
6.3.3 Six Methods of Collecting Job Analysis Data
| Method | How it works | Best for |
|---|---|---|
| Observation | Analyst watches the job-holder work | Manual, short-cycle jobs |
| Interview | Structured/semi-structured conversation with job-holder and supervisor | Most jobs; especially knowledge work |
| Questionnaire | Standardised forms filled by job-holder | Large numbers of similar jobs |
| Daily diary / log | Job-holder records activities through the day | Managerial and professional jobs |
| Critical incident technique (Flanagan, 1954) | Documenting especially effective or ineffective behaviour | Identifying the core of the job |
| Position Analysis Questionnaire (PAQ) | 194 standardised job elements rated for use (McCormick, 1972) | Cross-job comparison |
McCormick’s Position Analysis Questionnaire has 194 elements grouped into six divisions. NTA tests this exact number.
6.3.4 Components of a Job Description
| Component | Content |
|---|---|
| Job identification | Title, code, department, location, grade |
| Job summary | One paragraph on the purpose |
| Duties and responsibilities | The “what” — action-verb led |
| Working conditions | Hazards, physical demands, hours, travel |
| Relationships | Reports to, reports from, internal and external contacts |
| Authority | Decisions the job-holder may take alone / recommend / escalate |
| Performance standards | Yardsticks by which the job will be evaluated |
6.3.5 The KSAO Model of Job Specification
| Element | What it covers | Example for a sales manager |
|---|---|---|
| Knowledge | Body of facts | Product features, pricing rules |
| Skills | Practical proficiency | Negotiation, presentation, CRM software |
| Abilities | Underlying capacities | Numerical reasoning, persuasion, stamina |
| Other characteristics | Traits, attitudes, motivations | Drive, integrity, willingness to travel |
A further cut distinguishes essential vs desirable requirements.
6.3.6 Eight Uses of Job Analysis
| Use | How job analysis informs it |
|---|---|
| Recruitment & selection | Defines what to advertise for and what to assess |
| Training | Identifies the gap between current ability and job demand |
| Performance appraisal | Names the standards |
| Compensation | Job evaluation begins with the description |
| Career planning | Maps career paths and required moves |
| Health & safety | Identifies hazards and required protective measures |
| HR planning | Provides the units the workforce plan is built from |
| Legal compliance | Defines bona fide occupational qualifications; supports defence against discrimination claims |
6.4 C · Job Design
Job analysis describes the job as it is; job design changes the job as it should be. Four classical approaches dominate.
| Approach | What it does | Trade-off |
|---|---|---|
| Job simplification | Reduces the job to its smallest, repeatable element (Taylor) | High efficiency, low motivation |
| Job rotation | Moves the worker through different jobs in a cycle | Reduces boredom; brief disruption |
| Job enlargement (horizontal loading) | Expands the number of tasks at the same skill level | Variety without responsibility |
| Job enrichment (vertical loading) | Expands responsibility — planning, control, autonomy | Higher motivation; harder to design |
- Job enlargement = horizontal loading — more tasks at the same level.
- Job enrichment = vertical loading — more responsibility, autonomy, planning.
NTA stems exploit this distinction. Herzberg’s two-factor theory is the basis of job enrichment.
6.4.1 Herzberg’s Job Enrichment
Frederick Herzberg’s 1968 Harvard Business Review article — “One More Time: How Do You Motivate Employees?” — argued that motivators come from giving workers more of the job to manage themselves: planning, scheduling, quality-checking, problem-solving.
6.4.2 Hackman–Oldham Job Characteristics Model (1980)
Richard Hackman and Greg Oldham’s Work Redesign (1980) offered the most influential modern model. Five core job dimensions produce three critical psychological states, which produce four work outcomes — moderated by the worker’s growth-need strength.
| Core dimension | Definition |
|---|---|
| Skill variety | Different activities, different talents called upon |
| Task identity | Doing a whole, identifiable piece of work |
| Task significance | Impact on others’ lives or work |
| Autonomy | Freedom to schedule and decide how to do the work |
| Feedback | Direct, clear information about effectiveness |
| State | Produced by | Outcome |
|---|---|---|
| Experienced meaningfulness | Skill variety + Task identity + Task significance | High intrinsic motivation, high performance |
| Experienced responsibility | Autonomy | Low absenteeism and turnover |
| Knowledge of results | Feedback | High satisfaction with the work |
6.4.3 The Motivating Potential Score (MPS)
MPS = [(Skill variety + Task identity + Task significance) ÷ 3] × Autonomy × Feedback
Because autonomy and feedback are multiplicative, a job with zero on either is unmotivating regardless of the other dimensions.
Hackman-Oldham’s MPS formula multiplies autonomy and feedback with the average of the first three dimensions. NTA stems repeatedly test this — zero autonomy or zero feedback drives MPS to zero.

6.6 Quick Recall
- HRP = matching demand and supply of people. Five steps: Objectives → Demand → Supply → Gap → Action.
- HRP definitions: Vetter (movement to desired position), Walker (demand-supply-strategy).
- Demand-forecasting methods: managerial judgement, ratio-trend, work-study, regression, Delphi (anonymous, iterative), workforce analytics.
- Supply-forecasting methods: skill inventory, replacement chart, succession plan, Markov analysis, external scan.
- Job analysis produces job description (the job) and job specification (the person).
- Six job-analysis methods: observation, interview, questionnaire, diary, critical incident (Flanagan 1954), PAQ — 194 elements (McCormick).
- KSAO of a job specification: Knowledge, Skills, Abilities, Other characteristics.
- Eight uses of job analysis: recruitment, training, appraisal, compensation, career planning, health & safety, HR planning, legal compliance.
- Job design ladder: simplification → rotation → enlargement → enrichment.
- Enrichment = vertical loading (responsibility); Enlargement = horizontal loading (more tasks).
- Herzberg (1968) — job enrichment based on two-factor theory.
- Hackman-Oldham (1980) — five core dimensions: Skill variety, Task identity, Task significance, Autonomy, Feedback. Three critical psychological states: meaningfulness, responsibility, knowledge of results.
- MPS formula: [(SV + TI + TS) ÷ 3] × Autonomy × Feedback — autonomy and feedback are multiplicative.
