Job Analysis and Evaluation in Industrial/Organizational Psychology
Foundations of Job Analysis
Job analysis, also frequently referred to as work analysis, serves as the fundamental cornerstone for virtually all human resource (HR) activities within an organization. It is the systematic process of determining the specific work activities performed and the requirements necessary to perform those activities. The primary written outcome of this process is the job description, which is a relatively short but detailed summary of the tasks and job requirements identified during the analysis. A professional job description should typically range from to pages in length and must be described in exhaustive detail to be effective.
Job analysis and job descriptions provide the essential basis for numerous HR functions. They result in comprehensive lists of job activities that organizations use to create targeted training programs. One important, though often underutilized, application of job analysis is identifying worker mobility. By analyzing a job, HR professionals can determine the path of promotion—specifically, which other roles a successful individual might eventually transition into. This is particularly relevant in avoiding the Peter Principle, a phenomenon where employees are promoted based on success in their current role until they eventually reach their highest level of incompetence in a role they are not suited for.
Furthermore, job analysis data is critical for constructing performance appraisal instruments, classifying jobs into groups based on similarities in requirements, and determining the overall worth of a job to establish pay levels. It is also used to identify the optimal methods for performing tasks and serves as a legally acceptable way to demonstrate job relatedness. The Uniform Guidelines on Employee Selection (), which are federal HR principles designed to ensure compliance with standards, contain several direct references to the necessity of job analysis in selection procedures. Beyond administrative uses, the process allows job analysts to identify and address underlying organizational problems.
Components of a Good Job Description
A well-constructed job description must be thorough to prevent issues such as employees claiming, "It's not my job." To counter this, descriptions should be updated regularly as duties are added, and they should explicitly include the phrase "and performs other job-related duties as assigned." The document begins with a job title, which describes the nature of the work, provides the worker with a sense of identity, and influences external perceptions of the status and worth of the position. An accurate title is also vital for recruitment and selection.
Following the title, a brief summary—usually a paragraph in length—should describe the nature and purpose of the job. The work activities section specifies the tasks involving the worker. A dedicated section should list all tools and equipment required, which is primarily used for selection and training purposes. The job context section is equally critical, documenting the environment including stress levels, work schedules, physical demands, level of responsibility, temperature, number of coworkers, degree of danger, and other relevant environmental factors.
Work performance standards should be outlined to define how an employee's performance will be evaluated and what standards are expected. Financial information, such as the salary grade and whether the position is exempt, should be included alongside compensable factors used for salary determination. Finally, the job description must detail job specifications or competencies, known as KSAOs: Knowledge, Skills, Abilities, and Other characteristics necessary for success. These elements ensure that the right individuals are matched to the right roles.
Preparation and Participation in Job Analysis
While a job analysis is usually conducted by a trained individual from the HR department, it can also be performed by job incumbents, supervisors, or outside consultants. Consultants are often preferred due to their extensive training and experience, while college interns are sometimes used as an alternative. It is vital that job descriptions are updated whenever a job changes significantly. This includes accounting for job crafting, which refers to the informal changes employees make to their own roles over time.
Participation should ideally involve all employees. There are two primary approaches: committee-based and field-based. In a committee-based analysis, a group of subject matter experts (SMEs) meets to generate tasks, conditions, and KSAOs. In field-based analysis, the analyst observes or interviews incumbents individually in their actual work environment. Choosing the right participants is a sensitive issue, as data shows that high-performing employees and more experienced employees rate tasks differently than low-performing or less experienced ones. Research has also indicated small but significant differences in job perceptions based on race, gender, and the personality of the incumbent. Analysts must also decide the level of granularity: should the analysis focus on minute, specific behaviors or more general levels? For intricate work, expensive efforts may be required to find the optimal task sequence. Analysts must also differentiate between formal requirements, like filing memos, and informal requirements, like making coffee.
The Five Steps of Conducting a Job Analysis
The first step in a job analysis is to identify the tasks performed. This involves identifying major job dimensions, tools used, and work conditions. Information is gathered through existing documentation, observing workers (though observing without their knowledge is difficult), job participation (which is highly effective), and interviewing SMEs. Interviews can be individual or conducted via an SME conference with a larger group. Analysts should prepare by announcing the process to employees, establishing rapport, using open-ended questions, and allowing ample time for responses.
The second step is writing task statements. A task statement must contain an action (what is done) and an object (to which the action is done), as well as details on where, how, why, and when. The rule is "one action equals one object." These must be written at a reading level appropriate for the typical incumbent, use consistent tense, include tools, and describe activities rather than policy or competencies. The level of authority for decision-making must also be clearly indicated.
Step three involves rating the task statements through a task analysis. A group of SMEs rates each statement based on the frequency of the task and its importance or criticality. Step four is determining the essential KSAOs. Knowledge is the body of information needed; Skill is the proficiency in a learned task; Ability is the basic capacity to perform tasks or acquire new ones; and Other characteristics include personality, interest, and motivation. Once identified, another group of SMEs rates how essential each KSAO is. The fifth and final step is selecting the appropriate tests to tap into these KSAOs at the time of hire.
Standardized Job Analysis Methods
Several methodologies exist for gathering general information about worker activities. The Position Analysis Questionnaire (PAQ) consists of items across six dimensions: information input, mental processes, work output, relationships, job context, and other variables. While inexpensive and fast, its instructions are written at a college graduate level and it lacks specific task detail. The Job Structure Profile (JSP) is a revised version of the PAQ with improved discriminatory power in intellectual dimensions. The Job Elements Inventory (JEI) is similar to the PAQ but written at a -grade level. Functional Job Analysis (FJA) is a fast method used by the federal government to compare thousands of roles.
Other methods focus on specific aspects of the job. For tools and equipment, the Job Components Inventory (JCI) uses over questions. For the work environment, the AET (Arbeitswissenschaftliches Erhebungsverfahren) is an ergonomic procedure focusing on the relationship between worker and object. Competency-based methods include ONET (), a federal system replacing the Dictionary of Occupational Titles. ONET analyzes work at four levels: economic, organizational, occupational, and individual. The Critical Incident Technique (CIT) identifies incidents of excellent versus poor performance to distinguish successful behavior. Other competency tools include Threshold Traits Analysis (TTA) with items, the Fleishman Job Analysis Survey, the Job Adaptability Inventory (JAI) with items focusing on types of adaptability, and the Personality-Related Position Requirements Form with items based on the Big traits.
Evaluation of Methods and Job Evaluation
The choice of method depends on the intended use. Worker-oriented methods are superior for selection and appraisals, while job-oriented methods are better for writing descriptions and work design. Legally, courts prefer analyses that use multiple up-to-date sources, expert analysts, and large samples of incumbents. Task analysis provides the highest quality results and best job picture but is the most time-consuming and requires the most training. The PAQ is the most standardized and least costly, but it is often rated as the least useful. The CIT is the least standardized but often rated as highly useful.
Job evaluation is the separate process of determining a job's financial worth, occurring in two stages: internal and external equity. Internal pay equity involves comparing jobs within the firm to ensure fair pay based on compensable factors such as responsibility, physical demands, mental demands, education, training, and working conditions. External pay equity compares the job to the market using salary surveys to determine direct compensation. Finally, sex and race equity must be maintained through pay audits using SSEGs (Similarly Situated Employee Groupings). Statistical tools like hierarchical regression and Fisher's exact tests are employed to compare median salaries and ensure no discriminatory pay gaps exist between gender or racial groups.
