METHODS FOR THE EMPLOYEES’ PERFORMANCE EVALUATION Sebastian Adrian Uriesi PhD Student at the Faculty of Economics and Business Administration, “Al.I.Cuza” University, Iasi, Romania E-mail address: md.personal@yahoo.com Abstract Employee’s performance has the same landmark as the employee’s motivation, namely the employee’s behaviour. Thereby, a definition of this concept might be (Campbell, 1990): “the employee’s performance represents the behaviours which are relevant the company’s purposes and which can be measured by taking into consideration the subject’s contribution to these purposes.” Therefore, the essential element in evaluating behaviours in terms of performance is the distance between them and the standard enforced by the organisation in this matter. Keywords: performance, motivation, evaluation, methods, employees, programmes. - Employee’s performance has the same landmark as the employee’s motivation, namely the employee’s behaviour. Thereby, a definition of this concept might be (Campbell, 1990): “the employee’s performance represents the behaviours which are relevant the company’s purposes and which can be measured by taking into consideration the subject’s contribution to these purposes.” Therefore, the essential element in evaluating behaviours in terms of performance is the distance between them and the standard enforced by the organisation in this matter. The relationship between motivation and performance is one of determination: high levels of motivation produce, at least in theory, high levels of performance. Nevertheless, this is not a relationship of absolute causality, because in every organisational context there are two other important factors, namely: the subjects’ ability – their capacity to develop their tasks; situational constrains, that is the opportunities provided by the organisation in order to complete this tasks. Therefore, both motivation and abilities and actual conditions determine the employees’ performance. High levels of performance can be met when every one of the three factors is present at a high level – the individuals have the necessary abilities, they are fully motivated and the work environment helps them manifest those behaviours. On the other side, in case of a lower level of performance, there are four possible causes. (According to Muchinski, 2000): a) too high organizational standards – it is possible that within another organization, the same behavior would be considered efficient; b) lack of the subjects’ personal abilities, necessary for the successful result of the necessary behavior; c) insufficient motivation of the subjects in order to show the required behavior; d) lack of equipments or opportunities necessary in order to develop the behavior required by the standards. Once the performance criterion has been identified, an evaluating instrument needs to be created for individual performances. Organizations have used various recording techniques for performance evaluation throughout the years. Method selection is a very important aspect, since it may have an impact both on the evaluation accuracy and on the employees’ satisfaction degree. Moreover, there are research works that have shown that even the evaluator’s characteristics may have influence the performance evaluation (Hartel, 1993). Research in the field underline the importance that an appropriate construction of performance evaluating methods has for the success of its stimulating programmes by financial means. At this point, we may mention two essential recommendations resulting from the study completed by Kauhanen and Piekkola (2006) on the population of Finnish clerks. First of all, the efficiency of the performance financial remuneration programmes is increased if their assessment is placed on a level that is closest to the employee; in other words, the individual level, or the team level, at most, is preferable to the department level of the level of the entire organization. Secondly, the employees must know the details of the criteria and the methods based on which their performances are to be evaluated. We are hereby going to briefly present the most frequently used general methods for the employees’ performance evaluation. 1. COMPARATIVE METHODS Comparative methods refer to an employee’s performance as being connected to the other people’s performance. These methods, which require hierarchies, paired comparisons or forced distribution, are more easily applicable than other approaches. The hierarchy ranking method requires the supervisor’s ordering the employees within a hierarchy, from the best to the poorest, according to a particular dimension, such as productivity or performance in general. Good and bad employees may be easily identified in a ranking of this kind; moreover, this method has an increased degree of fidelity among evaluators, and it is easy to use. The major problem of this method is the fact that it does not provide an actual performance evaluation. For instance, a telephone operator may process 20 calls per hour, while a second operator will process 10 calls, and the third operator 5. A hierarchical order cannot provide an increased degree of subjects’ differentiation. On the other, 20 calls per hour may reflect the poorest performance of another group in another department. Another problem referring to this method is that it is difficult to apply on a big number of employees, and the hierarchical order does not provide information on the monitored criteria. The best operator may just as well be superior or inferior to a particular criterion. The hierarchical order may certainly tell the supervisor only if some employees are better than others. Paired comparisons is a method by means of which the supervisor compares each employee to all the others, making all the possible pairs of two employees, and identifying the best employee in every pair, whether based on separate dimensions, or based on the professional efficiency as a whole. Despite the fact that this method is precise and efficient in practice, its use may become difficult if the assessed group exceeds 50 employees, since there will be a number of 1225 pairs. Forced distribution - If the number of the assessed employees is very big, and there is no claim of a highly accurate evaluation, a coarse distribution may be achieved by means of the forced distribution method. The evaluator distributes the assessed employees based on the Gaussian curve, including each subject in a class, according to previously established percentages. Usually, the curve is distributed in 5 proportional categories, as follows: 10% very good, 20% good, 40% medium, 20% poor, 10% very poor. At first, the evaluator distributes the subjects to the very poor class, followed by the class of the good ones and the class of the poor, while those who remain undistributed are construed as moderate. Although the paired comparisons and the forced distribution, as well as the method of the hierarchical ranking are easy to use, they all have the same problem related to the criterion. – they do no provide indications on the fact that an individual’s performance is superior or unacceptable. All the assessed employees may be remarkable or unsatisfactory, the only certain piece of information being that some of them are better or worse than others. The comparison of some people’s position to others’ does not provide information on the performance level itself. This is why there are some performance evaluation specialists who do not approve of this category of methods, and therefore they are not very much used. 2. ATTRIBUTE LISTS The lists of attributes are the lists of those particular features of behaviours that the supervisor checks as relevant for the employees’ performance. These methods are easy to elaborate and use, although their main disadvantage is that they are focused on the “all or nothing” evaluation criterion; for example, the employees are evaluated as cooperating whether all the time, or not at all. Another disadvantage regarding the simple lists of attributes refers to the fact that all the behaviours or features that are relevant for the job are construed as equally important or, in fact, as far as many jobs are concerned, tasks have different importance level. In order to overcome this issue, certain mixed lists of attributes have been created, a set of discriminating lists as far as the importance of various tasks are concerned. When certain aspects of job performance are more important than others, various scores are awarded for each task. Ideally, this method provides important data for both the evaluator, and the evaluated person, the latter being aware of the value that different tasks have, and may therefore appropriately direct their efforts. An important issue raised by such lists is the evaluator’s tendency towards indulgence or strictness. Since supervisors are aware of the fact that they positively or negatively evaluate an employee, this type of knowledge may interfere with the accuracy of the evaluation. The forced-choice attribute lists have been created precisely in order to eliminate this disadvantage. According to the lists in this format, supervisors are presented groups of four sentences referring to various aspects of job performance. Two of them are positive, and two negative. Only one of the positive sentences is relevant to the performance, while only one negative sentence is relevant to an unacceptable performance. Considering the fact that the evaluator cannot identify the positive connotation of the sentence at first glance, there is a reduced risk of errors. Moreover, evaluators are not allowed to score the evaluation instrument, since this operation is performed by others. Although the forced-choice attribute lists seem to control indulgence, there are, however, two obvious disadvantages. First of all, the elaboration of such a scale requires the assistance of trained professionals, and the creation of the four relevant and plausible performance descriptors is costly and time-consuming. Secondly, supervisors are not very receptive in using evaluation forms when they do not know the results. Therefore, the forced-choice attribute lists are scarcely outspread. 3. EVALUATION SCALES Evaluation scales allow the employees’ performance to be evaluated throughout a continuum that varies from “always” to “never”. This evaluation format provides more accuracy to individual performance than the hierarchical ordering or the lists of attributes. Graphic scales, which were introduced in 1922, represent the first quantitative evaluation technique of performance. These scales use a feature description throughout a continuum that the employee is evaluated upon. For instance, employees may be evaluated as “extremely reliable”, “very reliable”, “reliable”, “occasionally reliable”, and “unreliable”. The manager checks the level that corresponds to the employee within this continuum. Graphic scales are easy to create and use, but a correct application requires a profound understanding of what the described behaviour means. For example, supervisors may have problems in making the difference between the “reliable” performance and the “extremely reliable” one, unless these terms are sufficiently operationalized. Mixed standard scales have been elaborated by Blanz and Ghiselli (1972) precisely in order to reduce the halo and indulgence errors in performance evaluation. The reason beyond this method is the fact that the evaluation will be more accurate if the evaluator has access to behavioral description at various levels. Three critical incidents on “good”, “medium” and “poor” performance are summarized in this format, on an evaluation scale taking the forms of statements. These statements are randomly arranged, and it is therefore difficult for the evaluator to identify the valence of the statement. Evaluators write “+” when the employee’s performance is superior to the standard, “-” when the performance reflects the bottom level of the standard, and “0” when it is equal to the standard. Although a mixed standard scale seems to control biases, it still raises questions on fidelity. Moreover, this scale has the disadvantage of being difficult to use, and with a timeconsuming elaboration. Another evaluation instrument, which has become quite popular in the last years, is the behaviorally anchored rating scale, introduced by Smith and Kendall (1963). This scale includes paragraphs describing working behaviours that are considered “excellent”, “good”, “poor”, etc. Thus the supervisor has concrete examples by means of which an evaluative assessment of working behaviours may be achieved, which, most of the time, increases the precision (accuracy) of the evaluation. A method that is based on this behaviorally anchored rating scale is the behavioral observation scale; in its first stage, the evaluator collects information about critical incidents and uses these data in order to elaborate categories of tasks implied by that job. Unlike the previous type of scale, the behavioral observation scale uses a continuum to measure the occurring frequency of those behaviours in the case of the evaluated employee, based on several reference points such as “never”, “very often”, etc. 4. NARRATIVE METHODS Although the current tendency in human resources management encourages the use of quantitative systems for performance evaluation, the narrative methods are still intensely used, especially for the evaluation of employees with managing responsibilities. This is due to the fact that the narrative methods have a superior applicability especially in the case of complex and unstructured working tasks, or when the development of quantitative reference points does not seem to be justified. One of the classical methods belonging to the narrative category is the evaluation essay method, when the evaluator describes the employee’s strong points and weaknesses, the fields where improvement is required, the potential purposes that may be set for that employee, as well as other qualities. A special advantage of this evaluation method is the provided opportunity to identify certain performance aspects, which may be “overlooked” when other evaluation methods are applied. The critical incident method represents another narrative approach of performance evaluation. In this case, supervisors make an inventory of each employee’s negative and positive behaviours, with the advantage that this method is based on real behaviours, not on the inferred behaviours of the evaluated people. Nevertheless, the disadvantage of the narrative methods is usually the fact that they are rather expensive and time-consuming, without necessarily bringing a significant plus to the accuracy of the completed evaluations. 5. MANAGEMENT BY OBJECTIVES This employee evaluation approach was developed by Peter Drucker in 1950’s, and it is widely applied in organizations nowadays. In the case of an evaluation system based on objectives, the manager identifies about seven or eight specific results that an employee should achieve within a particular time interval. The manager may also support the employee in planning the necessary steps for the achievement of these objectives; in other cases, this planning may be left entirely at the employee’s free will. Moreover, the objectives are generally established after the employees have been consulted; this is why this approach is very successful in organizations with participative management. The advantage of the management by objectives is the fact that employees clearly know what is expected from them before the evaluation period. It is also a more flexible approach compared to others, since its particular implementation means may be developed, modified or adapted much more rapidly. A disadvantage of this approach is the fact that it implies a rather “narrow” focus, on precise objectives, excluding other aspects of the activity, which may be important as far as performance is concerned. Thus, the employee may become exclusively preoccupied by the goals brought to the foreground, which are merely relevant for his subsequent evaluation, ignoring less important duties. The table hereby is a comparative presentation of the five evaluation methods for employees’ performance, as exposed in the previous pages, as well as their specific variants and their characteristics in terms of advantages and disadvantages. Method Comparative methods Type Hierarchical ranking Paired comparisons Forced distributions Advantages / disadvantages They are simple to develop and use; they provide comparisons between employees, but they do not establish the actual performance level. The simple variant is easy to develop and Lists of attributes Simple Mixed use, but it construes all behaviours as equally With forced important; problems related to the indulgence distributions tendency in the case of the mixed variant; forced choices control this problem, but they are difficult to develop. The graphic variant is easy to develop and Evaluation scales Graphics Mixed-standard use, but it requires a clear understanding of Behaviorally evaluations; the mixed-standard variant anchored controls this problem, but it is difficult to Behavioral develop; the behaviorally anchored and the observation behavioral observation ones increase accuracy, but they are rather costly. Evaluation essay They are particularly efficient when job tasks Narrative Critical incidents are poorly structured; they allow the methods evaluator to cover many areas; they may be influenced by the halo error. Employees clearly know what is expected Management by from them, and they may be involved in the objectives identification of these objectives; however, the method may have a rather narrow focus, and it ignores the external factors that may influence performance. Table 1. Comparisons of performance evaluation methods We may notice that one of the assessing criteria of these general performance evaluation methods is the one of their clarity to the evaluated persons. This issue underlines that importance of the employees’ perception and reaction on their own professional performance evaluating process. One of the dimensions of this importance is the one of its influence on the efficiency of performance financial rewarding programmes: in the case of an evaluating system that the employees suspect as imperfect, contaminated or subjective, the purposes of such programmes cannot be achieved. Therefore, the topic of performance evaluation methods is extremely important, both at the objective level – of the actually practiced methods for performance measuring – and on the subjective level, of how they are perceived by the employees.
