2.1 Role of human resource management

Human resource management (HRM) is the part of a business that plans for, recruits, develops, rewards and looks after its people so that the organization can reach its objectives. In practice that covers:

  • workforce planning: how many people, with which skills, and when
  • recruitment and selection
  • training and development
  • performance appraisal and reward
  • retention, welfare and employee relations
  • supporting the organization through change

The key point is that HRM serves the strategy of the whole business. A hotel chain planning to open in three new cities needs HRM to forecast the staff it will need, recruit them in time and train them to the same standard. Poor HR planning shows up as unfilled posts, high labour costs, low morale and weak customer service.

A hub-and-spoke diagram with business strategy in the centre and six HR activities around it: workforce planning, recruitment and selection, training and development, appraisal and reward, retention, welfare and employee relations, and supporting change. Poor HR planning shows up as unfilled posts, high labour costs, low morale and weak service.
HRM covers six activities, all serving the strategy of the whole business.

Internal and external factors in human resource planning

Human resource planning is the process of forecasting the number and type of employees a business will need and matching that to the people it has. Factors fall into two groups.

Internal factors come from inside the business:

  • business objectives and growth plans, such as launching a new product
  • the existing workforce: ages, skills, expected retirements and labour turnover
  • budget available for wages and training
  • organizational structure and culture
  • working patterns the business offers, such as flexi-time

External factors come from outside:

  • demographic change: an ageing population shrinks the pool of young workers and raises demand for health services; a falling birth rate does the same to future recruitment
  • change in labour mobility: how easily workers move between jobs, regions or countries
  • immigration: can fill skills shortages but depends on rules the business does not control
  • the gig economy: platform-based, short-term or freelance work
  • other factors from a STEEPLE analysis (social, technological, economic, environmental, political, legal, ethical)

Flexi-time is listed among the factors. Under flexi-time, employees complete agreed hours but choose when they start and finish, usually around core hours. It affects planning because the business must make sure that enough people are present at busy times. It can also help recruitment and retention, because it suits parents, carers and long-distance commuters.

Worked example: Ledburn Bakeries

Ledburn Bakeries runs 20 shops in a region where the working-age population is falling and many bakers are near retirement. Management plans 6 new shops.

  1. Internal factors: expansion needs about 6 more shop teams; several skilled bakers will retire within five years; the training budget is fixed.
  2. External factors: demographic change reduces local recruits; better public transport raises labour mobility, so rivals can attract Ledburn’s staff; the gig economy offers part-time delivery drivers, but not bakers trained in the company’s methods.
  3. HR plan: start an apprenticeship scheme now, offer flexi-time to keep older bakers longer, and use gig drivers only for delivery peaks.

This answer works at AO2 because each factor is linked to a consequence for the plan, not just named.

Internal factors (6 more shop teams, retiring bakers, fixed training budget) and external factors (demographic change, labour mobility, gig economy) feed into the HR plan: an apprenticeship scheme, flexi-time to keep older bakers, gig drivers only for delivery peaks.
Each internal and external factor leads to a consequence for the HR plan.

Reasons for resistance to change

Resistance means employees (or managers) oppose or slow a change. Common reasons (the guide names the content point but not the items, so this list is our own wording):

  • fear of job loss or reduced hours
  • fear of the unknown and loss of routine
  • loss of status, power or responsibility, which often affects managers
  • lack of skills or confidence to work in the new way
  • low trust in management or poor earlier experience of change
  • disagreement that the change is needed or that it will work
  • extra workload during the transition
  • loss of social groups when teams are broken up

To reach AO2 you should connect the reason to the context. A supervisor whose team is about to be merged is more likely to resist because of lost status. A shop-floor worker told only that the factory is “moving to automation” is more likely to resist because of fear of redundancy.

Force field analysis (HL only) lists the driving forces for a change and the restraining forces against it, then weighs them. Resistance is one restraining force. Reducing restraining forces is usually more effective than adding more pressure.

Six reasons for resistance paired with a strategy: fear of job loss with job security promises; fear of the unknown with early honest communication; lack of skills with training; doubt it will work with consultation; low trust with visible leadership; loss of status with incentives.
Each source of resistance has a matching HR strategy, but the best choice depends on the situation.
Arrows scaled to scores for driving and restraining forces before and after action: drivers 12 against restrainers 10 (lead 2), then restrainers fall to 7 (lead 5) after a retraining pledge and course.
Weakening restraining forces widens the lead of driving forces.

HR strategies for reducing the impact of change and resistance

This content is assessed at AO3, so you need to judge, not just list. Strategies include the following (our own wording, as the guide gives no list):

Strategy How it helps Limitation
Early, honest communication Reduces rumours and fear of the unknown Time-consuming; bad news may still upset people
Consultation and participation Employees help design the change, so they own it Slows decisions; management may not accept the ideas
Training and retraining Removes skills-based fear Costs money and time
Phased introduction or pilot Lets problems be fixed on a small scale Delays benefits; uneven treatment
Incentives and job security promises Offsets personal loss Promises can be hard to keep
Redeployment, voluntary redundancy or support for those leaving Treats people fairly and protects reputation Costly
Visible leadership and support Builds trust Needs consistent behavior

A good evaluation chooses between these. If the change is urgent, such as a sudden market collapse, full consultation may be impossible and clear communication plus support may be the realistic choice. If the change is long-term and the workforce is highly skilled, participation is likely to bring better ideas as well as less resistance. State the condition that decides your judgement.

2.2 Organizational structure: terminology

An organizational structure is how a business arranges its people into roles, reporting lines and groups. The guide lists the nine terms below without definitions, so these are standard forms.

  • Delegation: passing authority to carry out a task, with the responsibility for doing it, to a subordinate. The manager remains accountable for the outcome.
  • Span of control: the number of subordinates who report directly to one manager.
  • Levels of the hierarchy: the layers of authority from top to bottom.
  • Chain of command: the line of authority and communication from the top of the organization to each employee.
  • Bureaucracy: a system of clear rules, procedures and formal roles. It gives consistency and control but can slow decisions and discourage initiative.
  • Centralization: decision-making kept at the top or head office.
  • Decentralization: decision-making passed to lower levels, branches or departments.
  • Delayering: removing one or more levels of the hierarchy, usually middle management.
  • Matrix structure: employees report to two managers at once, for example a functional manager and a project manager, so that cross-functional teams can be formed.

Relationships between these matter. A wide span of control means fewer levels and a flatter structure. Delegation makes decentralization possible. A long chain of command slows communication and makes it more likely that messages are distorted.

Worked example: levels and span

Suppose a business has 300 employees and every manager has exactly 6 direct reports. Layers hold 1, 6, 36 and 216 people. Four levels hold only 259, so at least five levels are needed. If the span rises to 20 across the board, 1, 20 and 400 people fit in three layers, so three levels are enough. The wider span cuts the chain of command, but each manager supervises more people.

Stacked level charts for 300 employees. Span 6: layers hold 1, 6, 36 and 216 people (259), so the remaining 41 need a fifth level. Span 20: 1, 20 and 279 people fit in three levels.
A wider span needs fewer levels and gives a shorter chain of command, but each manager supervises more people.
Delegation: a manager passes authority and the task to a subordinate but stays accountable. Centralised: decisions at the top of the hierarchy. Decentralised: decisions spread to lower levels. Bureaucracy: clear rules and formal roles give consistency but can be slow.
Who makes decisions, and how rules shape them.

Organization charts

A chart is a diagram of positions and reporting lines.

Tall (vertical) structure: many levels, narrow spans, long chain of command. Close supervision and clear promotion steps, but higher management cost and slow communication.

Flat (horizontal) structure: few levels, wide spans. Faster communication and lower management cost, and employees gain more responsibility; but managers can be overloaded and promotion routes are limited.

Sketch of each, in words:

Tall:    Director
         -> 3 managers
            -> 4 supervisors each
               -> 5 staff each

Flat:    Director
         -> 12 team leaders and staff directly

Charts can also group by function (marketing, finance, operations, HR), by product (each product line has its own team) or by region (each geographic area has its own team).

  • By function builds specialist expertise but can create silos.
  • By product suits a firm with distinct product lines but duplicates roles.
  • By region suits international or multi-location firms and local knowledge, but risks inconsistency between regions.

AO4 means you should be able to read a chart and calculate from it, such as span at each level or how many people sit below a given manager.

Four small organisation charts: by function (marketing, finance, HR), by product, by region, and a matrix where each employee reports to a function manager and a project manager.
Staff can be grouped by function, product or region, or in a matrix with two reporting lines.
Chart with directors above one manager, who has three supervisors with two staff each. A downward arrow marks the chain of command; the manager's span of control is 3. A lower panel shows the same 8 workers as a tall structure (4 levels, span 2) and a short structure (2 levels, span 8).
Levels, chain of command and span of control decide whether a structure is tall or short.

Appropriateness of structures when external factors change

AO3 needs a judgement with reasons. Use this approach: identify the change, state what it demands of the organization, then compare structures against that demand.

  • Fast technological change or unstable markets favour a flat, decentralized or matrix structure that can react quickly.
  • Expansion into other countries often favours structure by region, with more local decision-making.
  • Tight legal or safety rules favour bureaucracy and centralization so that compliance is consistent.
  • A sharp economic downturn often triggers delayering to cut costs, but too much cutting can overload managers.
  • A shift toward remote work or the gig economy may make a flat structure, or an HL-only project-based one, more suitable than a tall one.

Example: Ledburn Bakeries has a managing director, 4 area managers, 20 store managers and 160 shop staff, so the MD has a span of 4. Online ordering suddenly doubles demand for same-day delivery. Removing the 4 area managers would give the MD a span of 20, which is probably too wide. A better answer might decentralize delivery decisions to store managers while keeping area managers for a smaller group of stores.

Delayering also has a cost side. If each area manager earns 52,000 and four are removed, annual salary savings are 208,000. If each receives a 14,000 redundancy payment, the first-year net saving is 152,000. Against this, set lost experience, a heavier workload on those who remain and possible damage to morale.

HL only: changes in organizational structure

Content for HL only includes examples such as the project-based organization, in which temporary teams form around projects, and Charles Handy’s “Shamrock Organization”. Handy’s model splits the organization into three leaves: a core of essential, permanent staff; contractors who do non-core work; and a flexible, often part-time or temporary workforce. It links directly to the gig economy and flexible labour in section 2.1.

A shamrock with three leaves: core of essential permanent staff, contractors doing non-core work, and a flexible part-time or temporary workforce. HL only.
Handy's Shamrock splits an organisation into core staff, contractors and a flexible workforce.
Two charts. Before: managing director, 4 area managers, 20 store managers, 160 shop staff, span 4. After removing the area managers: span 20. Savings: 4 x 52,000 = 208,000, redundancy 4 x 14,000 = 56,000, net 152,000 in year one.
Removing four area managers widens the MD span from 4 to 20 and saves 152,000 net in year one.
Higher level only. A timeline with three overlapping projects, each with its own temporary team that forms at the start and disbands at the end.
In a project-based organization temporary teams form around projects.
Two charts of Pelican Freight. Before: CEO, 3 directors, 15 managers and 180 drivers, with the CEO span at 3. After removing directors the 15 managers report to the CEO, span 15, saving 270,000 pounds a year.
Delayering saves cost but widens the span of control.

Common errors

  • Defining span of control as the total number of employees rather than direct reports.
  • Saying delayering “removes workers” when it removes levels, usually of management.
  • Calling every flat structure better. Fit with the external environment decides.
  • Describing resistance only as laziness. Most employee concerns are rational.
  • Listing HR strategies with no judgement, when the content is AO3.
  • Mixing up centralization (decisions kept at the top) with a tall hierarchy (many levels). They often go together but are different ideas.

Frequently asked questions

What is human resource planning? Human resource planning is forecasting the number and type of employees a business will need and matching them to the staff available. It is influenced by internal factors such as growth plans and the existing workforce, and external factors such as demographic change, labour mobility, immigration and the gig economy.

What is the difference between a tall and a flat organizational structure? A tall structure has many levels, narrow spans of control and a long chain of command, giving close supervision. A flat structure has few levels and wide spans, giving faster communication and lower management cost.

What is a matrix structure? In a matrix structure employees report to two managers at once, such as a functional manager and a project manager. It shares skills across projects but can lead to conflicting orders and unclear accountability.

How can HR reduce resistance to change? Strategies include early, honest communication, consultation and participation, training, and support such as job security promises or redeployment. Because this content is assessed at AO3, choose the strategy that fits the cause of resistance and state its limitation.
