Scientific Management and Job Specialization

Perhaps the earliest attempt to design jobs came during the era of scientific management. Scientific management is a philosophy based on the ideas of Frederick Taylor as presented in his 1911 book, Principles of Scientific Management. Taylor’s book is among the most influential books of the 20th century; the ideas presented had a major influence over how work was organized in the following years. Taylor was a mechanical engineer in the manufacturing industry. He saw work being done haphazardly, with only workers in charge. He saw the inefficiencies inherent in employees’ production methods and argued that a manager’s job was to carefully plan the work to be performed by employees. He also believed that scientific methods could be used to increase productivity. As an example, Taylor found that instead of allowing workers to use their own shovels, as was the custom at the time, providing specially designed shovels increased productivity. Further, by providing training and specific instructions, he was able to dramatically reduce the number of laborers required to handle each job.

Scientific management proposed a number of ideas that have been influential in job design in the following years. An important idea was to minimize waste by identifying the most efficient method to perform the job. Using time–motion studies, management could determine how much time each task would require and plan the tasks so that the job could be performed as efficiently as possible. Therefore, standardized job performance methods were an important element of scientific management techniques. Each job would be carefully planned in advance, and employees would be paid to perform the tasks in the way specified by management.

Furthermore, job specialization was one of the major advances of this approach. Job specialization entails breaking down jobs into their simplest components and assigning them to employees so that each person would perform a select number of tasks in a repetitive manner. There are a number of advantages to job specialization. Breaking tasks into simple components and making them repetitive reduces the skill requirements of the jobs and decreases the effort and cost of staffing. Training times for simple, repetitive jobs tend to be shorter as well. On the other hand, from a motivational perspective, these jobs are boring and repetitive and therefore associated with negative outcomes such as absenteeism. Also, job specialization is ineffective in rapidly changing environments where employees may need to modify their approach according to the demands of the situation.

Today, Taylorism has a bad reputation, and it is often referred to as the “dark ages” of management when employees’ social motives were ignored. Yet, it is important to recognize the fundamental change in management mentality brought about by Taylor’s ideas. For the first time, managers realized their role in influencing the output levels of employees. The concept of scientific management has had a lasting impact on how work is organized. Taylor’s work paved the way to automation and standardization that is virtually universal in today’s workplace. Assembly lines where each worker performs simple tasks in a repetitive manner are a direct result of job specialization efforts. Job specialization eventually found its way to the service industry as well. One of the biggest innovations of the famous McDonald brothers’ first fast-food restaurant was the application of scientific management principles to their operations. They divided up the tasks so that one person took the orders while someone else made the burgers, another person applied the condiments, and yet another wrapped them. With this level of efficiency, customers generally received their order within 1 minute.

Rotation, Job Enlargement, and Enrichment

One of the early alternatives to job specialization was job rotation. Job rotation involves moving employees from job to job at regular intervals. When employees periodically move to different jobs, the monotonous aspects of job specialization can be relieved. For example, Maids International Inc., a company that provides cleaning services to households and businesses, utilizes job rotation so that maids cleaning the kitchen in one house would clean the bedroom in a different one. Using this technique, among others, the company is able to reduce its turnover level. In a supermarket study, cashiers were rotated to work in different departments. As a result of the rotation, employees’ stress levels were reduced, as measured by their blood pressure. Moreover, they experienced less pain in their neck and shoulders. Psychophysiological stress reactions, trapezius muscle activity, and neck and shoulder pain among female cashiers before and after introduction of job rotation. 

Job rotation has a number of advantages for organizations. It is an effective way for employees to acquire new skills and in turn for organizations to increase the overall skill level of their employees. When workers move to different positions, they are cross-trained to perform different tasks, thereby increasing the flexibility of managers to assign employees to different parts of the organization when needed. In addition, job rotation is a way to transfer knowledge between departments. Rotation may also have the benefit of reducing employee boredom, depending on the nature of the jobs the employee is performing at a given time. From the employee standpoint, rotation is a benefit, because they acquire new skills that keep them marketable in the long run.

Is rotation used only at lower levels of an organization? Anecdotal evidence suggests that companies successfully rotate high-level employees to train managers and increase innovation in the company. For example, Nokia uses rotation at all levels, such as assigning lawyers to act as country managers or moving network engineers to handset design. This approach is thought to bring a fresh perspective to old problems. Wipro Ltd., India’s information technology giant that employs about 80,000 workers, uses a 3-year plan to groom future leaders of the company by rotating them through different jobs.

Job enlargement refers to expanding the tasks performed by employees to add more variety. By giving employees several different tasks to be performed, as opposed to limiting their activities to a small number of tasks, organizations hope to reduce boredom and monotony as well as utilize human resources more effectively. Job enlargement may have similar benefits to job rotation, because it may also involve teaching employees multiple tasks. Research indicates that when jobs are enlarged, employees view themselves as being capable of performing a broader set of tasks. There is some evidence that job enlargement is beneficial, because it is positively related to employee satisfaction and higher quality customer services, and it increases the chances of catching mistakes. At the same time, the effects of job enlargement may depend on the type of enlargement. For example, job enlargement consisting of adding tasks that are very simple in nature had negative consequences on employee satisfaction with the job and resulted in fewer errors being caught. Alternatively, giving employees more tasks that require them to be knowledgeable in different areas seemed to have more positive effects.

Job enrichment is a job redesign technique that allows workers more control over how they perform their own tasks. This approach allows employees to take on more responsibility. As an alternative to job specialization, companies using job enrichment may experience positive outcomes, such as reduced turnover, increased productivity, and reduced absences. This may be because employees who have the authority and responsibility over their work can be more efficient, eliminate unnecessary tasks, take shortcuts, and increase their overall performance. At the same time, there is evidence that job enrichment may sometimes cause dissatisfaction among certain employees. The reason may be that employees who are given additional autonomy and responsibility may expect greater levels of pay or other types of compensation, and if this expectation is not met they may feel frustrated. One more thing to remember is that job enrichment is not suitable for everyone.  Not all employees desire to have control over how they work, and if they do not have this desire, they may become frustrated with an enriched job.

Job Characteristics Model

The job characteristics model is one of the most influential attempts to design jobs with increased motivational properties. Proposed by Hackman and Oldham, the model describes five core job dimensions leading to three critical psychological states, resulting in work-related outcomes.

Empowerment

One of the contemporary approaches to motivating employees through job design is empowerment. The concept of empowerment extends the idea of autonomy. Empowerment may be defined as the removal of conditions that make a person powerless. The idea behind empowerment is that employees have the ability to make decisions and perform their jobs effectively if management removes certain barriers. Thus, instead of dictating roles, companies should create an environment where employees thrive, feel motivated, and have discretion to make decisions about the content and context of their jobs. Employees who feel empowered believe that their work is meaningful. They tend to feel that they are capable of performing their jobs effectively, have the ability to influence how the company operates, and can perform their jobs in any way they see fit, without close supervision and other interference. These liberties enable employees to feel powerful. In cases of very high levels of empowerment, employees decide what tasks to perform and how to perform them, in a sense managing themselves.

Research has distinguished between structural elements of empowerment and felt empowerment. Structural empowerment refers to the aspects of the work environment that give employees discretion, autonomy, and the ability to do their jobs effectively. The idea is that the presence of certain structural factors helps empower people, but in the end empowerment is a perception. The following figure demonstrates the relationship between structural and felt empowerment. For example, at Harley-Davidson Motor Company, employees have the authority to stop the production line if they see a blemish on the product. Leadership style is another influence over experienced empowerment. If the manager is controlling, micromanaging, and bossy, chances are that empowerment will not be possible. A company’s structure has a role in determining empowerment as well. Factories organized around teams, such as the Saturn plant of General Motors Corporation, can still empower employees, despite the presence of a traditional hierarchy. Access to information is often mentioned as a key factor in empowering employees. If employees are not given information to make an informed decision, empowerment attempts will fail. Therefore, the relationship between access to information and empowerment is well established. Finally, empowering individual employees cannot occur in a bubble, but instead depends on creating a climate of empowerment throughout the entire organization.
