Work design is the deliberate structuring of job content, methods, and relationships to influence motivation, satisfaction, and performance. The Job Characteristics Model (JCM) by Hackman and Oldham (1976) identifies five core job dimensions — skill variety, task identity, task significance, autonomy, and feedback — that produce three critical psychological states (experienced meaningfulness, experienced responsibility, knowledge of results) which in turn drive motivation and satisfaction. Jobs high on these characteristics produce higher internal work motivation, satisfaction, and quality of work. The model also specifies individual moderators: employees high in growth need strength respond more positively to enriched jobs. Beyond top-down design, job crafting recognizes that employees proactively reshape their own work — altering task boundaries, relationships, and the cognitive meaning of their role — to better fit their motives and strengths. Work design bridges motivation theory (which explains why people are motivated) and organizational intervention (which specifies how to change work to increase motivation).
Work design asks a deceptively simple question: how should jobs be structured to maximize motivation, satisfaction, and performance? The question has enormous practical significance because organizations can redesign jobs far more easily than they can change the personality traits or abilities of their workforce. If the structure of work itself is a major determinant of motivation, then redesigning jobs is one of the most powerful interventions available to organizations.
The historical trajectory moves from scientific management (Taylor, early 1900s) through job enrichment (Herzberg, 1960s) to the Job Characteristics Model (Hackman and Oldham, 1976) to job crafting (Wrzesniewski and Dutton, 2001). Taylor's approach simplified jobs to the point of maximum efficiency — each worker performing a single repetitive task. This reduced training costs and increased short-term output but created crushing monotony, high turnover, and adversarial labor relations. Herzberg's response was job enrichment: adding responsibility, autonomy, and meaningful content to jobs to engage the worker's intrinsic motivation. But Herzberg's theory lacked specificity — it did not tell you which aspects of a job to change, or for whom enrichment would work.
The Job Characteristics Model provided that specificity. Hackman and Oldham identified five core dimensions measurable with the Job Diagnostic Survey (JDS): skill variety (the degree to which a job requires different skills), task identity (completing a whole piece of work from start to finish), task significance (the job's impact on other people's lives), autonomy (freedom to schedule work and choose methods), and feedback (clear information about performance effectiveness). These produce three psychological states — experienced meaningfulness (from variety, identity, and significance), experienced responsibility (from autonomy), and knowledge of results (from feedback) — which drive internal motivation, job satisfaction, work quality, and low absenteeism. The Motivating Potential Score (MPS) combines these multiplicatively: a job must have at least some of all three state-producing dimensions to be motivating. A job that is highly significant but offers zero autonomy and zero feedback has an MPS of zero.
Job crafting represents a paradigm shift from top-down design to bottom-up adaptation. Rather than waiting for management to redesign their jobs, employees proactively alter what they do (task crafting), whom they work with (relational crafting), and how they think about their work (cognitive crafting). A software engineer who volunteers for cross-functional projects is task crafting. A nurse who builds deeper relationships with patients' families is relational crafting. A refuse collector who views their work as maintaining public health rather than picking up trash is cognitive crafting. Research shows that job crafting is associated with higher engagement, satisfaction, and person-job fit. It also explains why two people in the same formal job description can have vastly different experiences — they have crafted different actual jobs from the same raw materials.
The practical implication is that motivation is not solely an attribute of the person — it is substantially an attribute of the work. An unmotivated employee in a poorly designed job may become highly motivated when the same job is enriched with autonomy, significance, and feedback. This shifts the diagnostic question from "What is wrong with this employee?" to "What is wrong with this job?" — a reframing that has profound implications for how organizations approach engagement, retention, and performance problems.
