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.

TipTwo Textbook Definitions of HRP
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

TipSix 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

TipFive Steps in Human Resource Planning
# 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

TipSix Demand-Forecasting Methods
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

TipFive Supply-Forecasting Methods
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
NoteDistractor warning — Delphi vs Brainstorming
  • 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).

TipJob Analysis at a Glance
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

TipSix Steps in 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

TipSix Methods of Job Analysis Data Collection
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
NotePYQ anchor — PAQ has 194 elements

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

TipStandard Job-Description Skeleton
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

TipThe KSAO Model
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

TipEight 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.

TipFour Classical Approaches to Job Design
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
NoteDistractor warning — Enlargement vs Enrichment
  • 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.

TipHackman–Oldham — Five Core Dimensions
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
TipThree Critical Psychological States
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)

TipHackman–Oldham MPS Formula

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.

NotePYQ anchor — Autonomy and Feedback are multiplicative

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.
