Objective: Provide a concise, syllabus‑aligned explanation of human needs, the main motivation theories that incorporate those needs, and how managers can apply this knowledge in the workplace.
A human need is an internal state of perceived deficiency. When a need is felt, the individual is motivated to act in order to satisfy it. Needs are the starting point for all motivation theories covered in the Cambridge 9609 syllabus (section 2.2).
Motivation theories are grouped into content theories (what motivates people) and process theories (how motivation works). The table below summarises each theory, its historical context, the type of theory, the primary needs it addresses, a typical workplace example, and a brief limitation.
| Theory (Year) | Historical Context | Type | Key Need(s) Addressed | Typical Workplace Example | Key Limitation |
|---|---|---|---|---|---|
| Taylor – Scientific Management (1911) | Early‑20th c industrial revolution; focus on efficiency and standardisation. | Content | Financial / physiological | Piece‑rate pay, time‑and‑motion studies. | Over‑emphasises monetary incentives and ignores social/psychological needs. |
| Mayo – Human Relations (1930s) | Hawthorne studies; reaction against the mechanistic view of work. | Content | Social (belonging) | Team‑building activities, supportive supervision. | May overstate the impact of social factors and underplay individual differences. |
| Maslow – Hierarchy of Needs (1943) | Post‑war humanistic psychology; need‑fulfilment model. | Content | All five levels (physiological → self‑actualisation) | Progressive reward system from basic wages to career development. | Rigid ordering and strong Western cultural bias; needs can be pursued simultaneously. |
| Herzberg – Two‑Factor Theory (1959) | Motivation‑hygiene research in 1950s US manufacturing. | Content | Hygiene (safety, security) & Motivators (esteem, growth) | Safe work environment + recognition programmes. | Difficulty separating hygiene factors from motivators; relies on self‑reported data. |
| McClelland – Learned Needs Theory (1961) | Mid‑20th c focus on achievement motivation. | Content | Achievement, Power, Affiliation (acquired needs) | Target‑based bonuses, leadership roles, collaborative projects. | Ignores possible innate components; measurement of needs can be problematic. |
| Alderfer – ERG Theory (1969) | Simplification of Maslow during the rise of organisational behaviour research. | Content | Existence, Relatedness, Growth (condensed Maslow) | Competitive salary, mentorship, personal‑development courses. | Categories remain vague; the “regression” hypothesis is not consistently observed. |
| Vroom – Expectancy Theory (1964) | Cognitive approach to motivation emerging in the 1960s. | Process | Link between effort, performance and reward | Clear performance targets + transparent reward system. | Assumes rational decision‑making; difficult to quantify expectancy, instrumentality and valence. |
Human needs are internal deficiency states that drive behaviour. By understanding the range of need‑based content theories (Taylor, Mayo, Maslow, Herzberg, McClelland, ERG) and the process perspective of Vroom, managers can select appropriate financial and non‑financial motivators, set relevant objectives, define clear targets, and conduct performance appraisals that match employees’ dominant needs. This systematic approach improves engagement, productivity, and overall business performance while recognising the limitations of each theory.
