Revise Need theories for Cambridge 9990 (4.1.1)

Need theories are a group of influential theories in organisational psychology that share a common assumption: human behaviour is motivated by the desire to satisfy unmet needs. When a need is not satisfied, it creates a state of internal tension or 'disequilibrium' that drives an individual to engage in behaviours they believe will lead to the need's satisfaction, thereby reducing the tension. These theories focus on identifying the specific internal needs that energise and direct behaviour at work. The three most prominent need theories in the Cambridge A-Level syllabus are Maslow's Hierarchy of Needs, Herzberg's Two-Factor Theory, and McClelland's Theory of Acquired Needs. While they differ in their specifics, they all provide a framework for managers to understand what energises their employees.

Abraham Maslow proposed that human needs are arranged in a five-level hierarchy of prepotency. An individual is motivated to satisfy lower-level needs before they can be motivated by higher-level ones. The hierarchy, from bottom to top, is: Physiological (e.g., pay sufficient for food and shelter), Safety (e.g., job security, safe working environment), Love and Belonging (e.g., good relationships with colleagues, teamwork), Esteem (e.g., recognition, promotion, job title), and Self-Actualisation (e.g., challenging work, opportunities for creativity and personal growth). According to Maslow's progression principle, once a need is substantially satisfied, it no longer motivates, and the next level of need becomes the primary driver of behaviour. This theory provides an intuitive framework for understanding employee motivation in a holistic way.

Frederick Herzberg's research led him to propose the Two-Factor Theory, which distinguishes between factors that cause job dissatisfaction and those that cause job satisfaction. He called the first group 'Hygiene Factors'. These are extrinsic to the work itself and include aspects like company policy, supervision, salary, and working conditions. Their absence causes dissatisfaction, but their presence does not lead to satisfaction, only to a state of 'no dissatisfaction'. The second group, 'Motivators' or 'Satisfiers', are intrinsic to the job content. These include achievement, recognition, the work itself, responsibility, and growth. Their presence creates high levels of motivation and job satisfaction, but their absence does not cause dissatisfaction, merely a lack of satisfaction. The key insight is that satisfaction and dissatisfaction are not opposite ends of a single continuum.

David McClelland proposed that individuals are motivated by three primary needs that are acquired or learned from their culture and life experiences: the Need for Achievement (nAch), the Need for Power (nPow), and the Need for Affiliation (nAff). Unlike Maslow's universal hierarchy, the strength of these needs varies between individuals. People with high nAch thrive on challenge, seek feedback, and prefer tasks of moderate difficulty. Those with high nAff desire harmonious relationships and enjoy cooperative tasks. Individuals with high nPow want to influence and control others. McClelland distinguished between personal power (domination) and institutional power (organising others to achieve goals), with the latter being crucial for effective management. This theory suggests that people can be matched to jobs that best suit their dominant motivational profile.
