How to Write Job Descriptions: What is a job description? (Available to nonsubscribers.)

A job description is a written statement that describes the main objective of a job, its essential and nonessential functions, job qualifications, and other information on the job.

A job description may describe duties, skills, effort, responsibilities of the job, environmental and working conditions specific to the job, as well as the education and experience required to perform the job. It also may include information on tools and equipment used and relationships with other jobs.

Thirty people may hold the same job and, therefore, use the same job description. It is important to remember that a job description describes the job, not the person, or persons, who hold that job.

There are two basic types of job descriptions: “specific” or individual and “generic” or general. In addition, position descriptions often are written for individual, high-level managerial employees.

Specific or Generic?

The specific job description, which is discussed in more detail, provides information on all the essential duties and responsibilities assigned to one or more individuals performing the job. It is usually quite detailed and comprehensive and provides a sound basis for job evaluation, training, orientation, and human resources organizational planning. This type of description demands a thorough job analysis, considerable care and expertise in preparation, and an active effort to keep it useful and up-to-date. It is the soundest type of job description to use, and usually the most expensive to prepare. There is also a tendency to exclude incidental responsibilities and duties, and disagreements can arise between supervisors and employees when relatively minor job duties change.

>p>Generic job descriptions, on the other hand, are written in broadly stated general terms without identifying specific functions, tasks, and responsibilities. A generic description is applicable to a group of similar or near-similar jobs, and therefore the per-job cost of preparation is lower. However, because of the Americans with Disabilities Act (ADA), use of the generic job description is not recommended.

While the ADA doesn’t require job descriptions, it does require that applicants and employees are able to perform the “essential functions” of the job, with or without reasonable accommodation. The Equal Employment Opportunity Commission (EEOC) has said that one of the things the agency will look at when determining essential functions are job descriptions written before an employer advertises to fill an opening. Therefore, most companies—whether they are rewriting old descriptions or developing them for the first time—want them to reflect essential functions, and a generic description is not the best way to do that. In addition to this legal consideration, managers have found problems with generic job descriptions when they are not properly written or if the supervisor chooses to ignore the limitations built into the description.

No job description should be viewed as a perfect reflection of the job. The object of a good job description is to differentiate the job (or group of jobs) from other jobs and to set its outer limits.

The information for much of the job description often is obtained through what is called a job analysis. Its purpose is to identify the job, define it within established parameters, and describe its scope and content. The job analysis should be accurate, concise, and complete.

Why Are Job Descriptions Important?

Accurate job descriptions provide a basis for job evaluation, wage and salary surveys, and an equitable wage and salary structure. In particular:

  • Job descriptions clarify who is responsible for what within the company. They also help define relationships between individuals, between departments, etc. When used to advantage, they can settle grievances, minimize conflicts, and improve communications.
  • Job descriptions help the jobholder understand the responsibilities of the position. This not only enables the employee to assess the relative importance of everything he or she is accountable for, but also provides a sense of where the job fits into the company as a whole.
  • Job descriptions are helpful to job applicants, employees, supervisors, and human resources (HR) professionals at every stage in the employment relationship, from recruitment to retirement. They provide information about the knowledge, training, education, and skills needed for each job. They prevent unnecessary misunderstandings by telling employees what they need to know about their jobs. Best of all, they provide this information in a completely objective and impersonal way.
  • Job descriptions help management analyze and improve the company’s structure. They reveal whether all company responsibilities are adequately covered and where these responsibilities should be reallocated to achieve a better balance.

Finally, they provide a basis from which to determine whether a disabled applicant is otherwise qualified for the job and, if so, to assist in determining what accommodation would be required for the applicant to be able to perform the essential functions of the position.

So Many Jobs, So Little Time: The Bane

Despite these and other benefits, job descriptions traditionally have suffered a poor reputation among managers and HR staffers. In fact, job descriptions often end up being ignored. “Job descriptions? Sure, we have them. They’re in the bottom drawer of that file cabinet with the big stack of books in front of it.”

Why? It takes commitment to maintain a job description program. It means that someone must be vested with the responsibility of the program—i.e., it’s got to be part of someone’s job description. In addition, supervisors and managers must take time to participate in maintaining job descriptions.

More important, however, people forget just how important job descriptions are as “preventive medicine.” People forget to floss their teeth until they begin to have gum problems. In just the same way, people forget to maintain job descriptions until six months after an incumbent has left the job and the new person isn’t doing what the boss wants. Then it becomes a crisis and it takes a lot more effort to figure out whether the problem is a job performance problem, a personality clash between supervisor and subordinate, or simply that the new person in the job never was told clearly what the job entailed.

Doing It Right the First Time

However, one of the most common reasons a job description isn’t used is because it isn’t useful. In other words, it lacks validity, and therefore it fails to achieve its potential.

A job description is valid to the extent that it accurately reflects job content. An out-of-date job description is obviously not going to be valid. But even descriptions written yesterday can suffer from a lack of validity. A carefully conducted job analysis will go a long way toward heading off validity problems, but in the end the responsibility rests with the individual who actually writes the finished product.

If the final written job description fails to accurately reflect the job, consider some of the possible consequences: Candidates without the proper qualifications may be referred to department heads for hiring or promotion; jobs may be ranked improperly with others in terms of their worth to the organization; and employees may end up struggling to achieve unrealistic standards of performance. And this is only the tip of the iceberg!

It is unfortunate that the typical job description is often deficient in at least one of the following ways:

  1. The description exaggerates or downplays the importance of the job.
  2. It fails to pinpoint the critical elements that differentiate between successful and unsuccessful job performance.
  3. It ignores the decision-making aspects of the job.
  4. It either fails to focus on the job incumbent’s actual behavior or it defines required behavior in ambiguous terms.
  5. It describes worker requirements or characteristics that are not really needed to succeed in the job.

Above all, many job descriptions (an example of which follows) fail to answer some of the most basic questions that someone coming into the job might have. Suppose that you are a newly hired administrative assistant for the position described. Would you have enough information about the job to feel confident about what was expected of you and about your ability to meet the job’s performance standards? Read on to see what we mean.

Typical (But Not Terrific) Job Description

Job Title: Administrative Assistant

Responsibilities: Works under the direction of the supervisor, Customer Service Department

Duties:

  • —Creates and compiles reports
  • —Maintains inventory of supplies
  • —Arranges meetings and conferences
  • —Handles routine correspondence
  • —Answers phone and takes messages
  • —Other duties as assigned

Qualifications:

  • —High school diploma or equivalent
  • —Two years’ experience in a administrative assistant position, or equivalent education



What’s wrong with this job description? It lists the general duties performed by many administrative assistants. Because this company is probably using the same job description for a wide range of administrative assistant positions, it does not specify the nature of the reports, meetings, and correspondence involved. The employee could be working in an insurance office or a textile factory. The last item — “Other duties as assigned” — leaves the job description open to any additional duties the supervisor may want to include. An approach like this obviously simplifies the process of preparing job descriptions, but it isn’t very useful. A more specific description would answer these questions:

  • What are the essential functions of the job? Am I able to perform them, with or without reasonable accommodation?
  • What are the standards for acceptable job performance? How often must I “compile reports” (for example), and how much time will I be given to do so? How promptly must I answer the phone? How often will it ring? How many errors (if any) are allowed in typing correspondence?
  • What are the conditions under which this job is to be performed? What kind of computer or typewriter is available? How large is the filing system? Is it up-to-date? How much correspondence is there to answer? What working conditions might make certain tasks easier or harder to accomplish? Do certain duties require more work at certain times of the day, month, or year?
  • What “other duties” might be assigned fairly regularly?
  • Why is two years’ experience necessary? What skills, knowledge, or abilities is this experience supposed to represent?

As you can see, specific job descriptions, regularly updated, are very helpful to today’s HR practitioner. However, as you’ll see in the next chapter, organizations may have legal liability if job descriptions are not used correctly.
