Halo Errors in Performance Management Systems
- Anita Rajendran
Performance Appraisals are the backbone of Human Resources and a crucial aspect of the entire Performance Management System (PMS) but also the most difficult to implement. The effectiveness of a Performance Appraisal can be seriously impacted by the common errors that raters make. Halo is one such error and can be defined as "the influence of a global evaluation on individual attributes of a person" (Nisbett & Wilson, 1977, p. 250) or "the influence of a rater's general impression on ratings of specific ratee qualities" (Lance, LaPointe, & Stewart, 1994, p. 339). The article tries to understand the background and research done into halo error and whether there is clear evidence to suggest that there is a positive or negative link to rating accuracy due to Halo error. It attempts to see if there are ways in which an organization can effectively utilize these research findings to counter halo error or whether any experiments done are effective only in a laboratory setting. Finally review on whether this aspect of the performance appraisal can be incorporated into an actual performance appraisal system.

Halos in Christianity

...The halo was incorporated into Christian art sometime in the 4th century[citation needed] with the earliest iconic images of Christ, initially the only figure shown with one (together with his symbol, the Lamb of God). Initially the halo was regarded by many as a representation of the Logos of Christ, his divine nature, and therefore in very early (before 500) depictions of Christ before his Baptism by John he tends not to be shown with a halo, it being a matter of debate whether his Logos was innate from birth (the Orthodox view), or acquired at Baptism (the Nestorian view). At this period he is also shown as a child or youth in Baptisms, though this may be a hieratic rather than age-related representation [20] Nativity and Transfiguration of Christ, with cross haloes; the apostles, angels and prophets have plain ones. (1025-50, Cologne). A cruciform halo, that is to say a cross within, or extending beyond, a halo is used to represent the persons of the Holy Trinity, especially Jesus, and especially in medieval art. In Byzantine and Orthodox images, inside each of the bars of the cross in Christ's halo is one of the Greek letters Ο Ω Ν, making up ὁ ὢν — "ho ōn", literally, "the Existing One" — indicating the divinity of Jesus.[21] At least in later Orthodox images, each bar of this cross is composed of three lines, symbolising the dogmas of the Trinity, the oneness of God and the two natures of Christ. In mosaics in Santa Maria Maggiore (432-40) the juvenile Christ has...

...ERROR MANAGEMENT Error Management Cassandra Galarneau June 1, 2013 BCOM/275 Morris Polston Abstract When faced with having to manage errors, an immediate and organized response is of the utmost importance. Following company protocols will aid in controlling and rectifying the situation at hand. Communicating the facts surrounding the incident will provide the needed assistance in managing the issue, decreasing down-time and maintaining safety.

My actions and reactions to this problem can have a positive or negative impact on the final outcome. Error Management As a plant manager that has just learned a mistake has been made in the release of quarantined products, it is my responsibility to act in a professional, responsible and communicative manner. My decisions must be timely, expeditious and intuitive. “Being decisive in a crisis can mean the difference between success and failure” (Claiborne, 2011). I must take into consideration such issues as: Why did this happen? How did it transpire? When did it occur? What must be changed to ensure this will not happen in the future? How can this situation be controlled so our company does not lose the clients’ respect and trust? A situation such as this can make or break my future with this company.

Medication Errors

...In the 1999 research studies began to review the problem of medical errors and how they occurred. Studies and reports, such as the Institute of Medicine IOM report in 1999, strongly suggest that most medical errors are related to systems and processes and not individual negligence or misconduct. The IOM report recommended that the key to addressing medical errors is to focus on improving the processes used to deliver healthcare and not placing blame on the individuals involved. Approximately 1.3 million people are injured annually in the United States following "medication errors". The FDA defines a medication error as “any preventable event that may cause or lead to inappropriate medication use or harm to a patient”. The U.S. Food and Drug Administration (FDA) currently review medication error reports that come from drug manufacturers and through Med Watch, the agency's safety information and adverse event reporting program. The agency also receives reports about medication errors from the Institute for Safe Medication Practices (ISMP) and the U.S. Pharmacopeia. Some things the FDA has put into place to prevent medication errors: * Drug Name Review: To minimize drug name confusion, FDA reviews about 400 drug names a year that companies submit as proposed brand names. The agency rejects about one-third of the names that drug companies propose. * Drug Labels: FDA regulations require all over-the-counter (OTC) drug products (more than 100,000) to have a......

Excel Errors

...2. Spreadsheet Errors: What we think we can do What we know? 1. What are the leading causes of Spreadsheet errors? The leading causes of spreadsheet errors are a) Human incapability of doing complex cognitive tasks with accuracy, this is a limitation in human capability and this contributes partly to the errors that are caused in spreadsheets b) Lack of disciplined development practices is one of the most common reasons why spreadsheet contains errors. Many organization has policies in general about end user development in general, much less spreadsheet development c) Many developers build the models and hardwire it to one end result they are working without considering the constraints or different possible scenarios. This ultimately leads to the fact that the model doesn’t work for any other input variables other than the one that is being used to. d) Another common reason of spreadsheet errors is due to the overconfidence of the developers in the accuracy of the spreadsheets. They don’t spend time to test the spreadsheet for any possible errors e) We could also say innocence (in a sense of not knowing the excel capabilities) as one of the common reasons why spreadsheets has errors, people tend to learn from friends and coworkers without any proper training on Excel and its capabilities which ultimately lead in unstructured spreadsheet development 2. Why these errors are typically not detected? a)......

Errors in Communcation

...All three critical errors in communication identified by Hynes are correct in all types of work environments. Communication is the key to success, I believe that without a critical understanding a person cannot function or proceed to their daily operations. As an assistant manager at Wal-Mart, I deal with all of the three critical errors. Out of the three critical errors in communication I deal with the most at work has to be the assumption observation error. As an assistant manager, I have to plan out what to do with the items that are coming in on the trucks daily. The items can range from anywhere being hundreds to thousands items per day. I have to plan where to put the items with my other managers and department managers. The easiest way to plan is to get a print out of a truck listing that breaks down the items by departments. Then, we delegate the listing by departments to each individual department manager; for example: I give the electronics items listing to the electronics department manager and he or she gives me feedback on where to put the item. Then we have an afternoon meeting to type what items will go where, when it is unloaded from the truck. The assumption observation error comes into play when the overnight manager uses the information given to him or her on where to put the item. Usually all the trucks get the items unloaded by 7 pm and the employees start taking the items out at 9 pm, since it is less customer traffic at that time. Even with all the......

Medication Errors

...My involvement in the drug error is as follows. I was working on the night shift as the only qualified nurse with 2 nursing assistants. The late shift decided to administer the 10pm medications as a way of helping me. This however was key in me making the error that I did. If I had been left to do the 10pm medications by myself, this error would not have occurred. Patient PF was given her medication by the late staff, however she had spat them out. On going to give her these again, I also repeated her liquid medication which she had actually taken with the late shift before she spat out her tablets. PF took half the liquid before giving it back to me saying that she had already taken it and it was just her tablets that she didn’t take. She accepted the tablets no problem from me. I checked the BNF to see limits of medication and knew the extra that she had was well within the maximum dose. I also knew that she was not naive to medication and had been taking this medication for some time without any adverse effects. I checked her observations and BP, pulse and temp were all within normal limits. I continued with getting the other ladies ready for bed and carried on with my regular night time duties and once the ward was settled I filled in the datix form to report the error. It was at this time that I realised I should have notified someone earlier of the error. I contacted the AMART team as it was my understanding that they triage the calls to the duty doctor overnight.

...Running Head: LITERATURE REVIEW: HALO EFFECT   1 Literature Review: HALO EFFECT NO NAME GIVEN HERE Liberty University BUSI 600-B04 21 January 2013 LITERATURE REVIEW: HALO EFFECT Abstract 2 The term “Halo Effect” has several definitions. In conducting business research, it is important to understand which definition is to be used and apply that definition to the problem at hand. In this paper, we will attempt to define the correct version of the halo effect as it applies to this literature review. This paper will then look at the history of the halo effect in business and define how it is being used today. During the writing, examples and studies regarding the halo effect that have already been completed will also be reviewed to see if the halo effect can genuinely and repeatedly be used in business to increase profits or generate revenues. LITERATURE REVIEW: HALO EFFECT Literature Review: Halo Effect Introduction Definition When discussing and researching the term “Halo Effect” the various definitions of the 3 phrase must be reviewed. Once reviewed, the researcher then has the responsibility to determine which definition best fits their research question at hand in order to best formulate the research design and subsequent answer. One of the definitions of halo effect is from the textbook Business research methods by Donald Cooper. It is defined as “error caused when prior observations influence perceptions of current observations” (Cooper &......

Halo Effect

...The halo effect refers to a bias whereby the perception of a positive trait in a person or product positively influences further judgments about traits of that person or products by the same manufacturer. One of the more common halo effects is the judgment that a good looking person is intelligent and amiable. There is also a reverse halo effect whereby perception of a negative or undesirable trait in individuals, brands, or other things influences further negative judgments about the traits of that individual, brand, etc. If a person "looks evil" or "looks guilty" you may judge anything he says or does with suspicion; eventually you may feel confident that you have confirmed your first impression with solid evidence when, in fact, your evidence is completely tainted and conditioned by your first impression. The hope that the halo effect will influence a judge or jury is one reason some criminal lawyers might like their clients to be clean-shaven and dressed neatly when they appear at trial. The phrase was coined by psychologist Edward Thorndike in 1920 to describe the way commanding officers rated their soldiers. He found that officers usually judged their men as being either good or bad "right across the board. There was little mixing of traits; few people were said to be good in one respect but bad in another."* The old saying that first impressions make lasting impressions is at the heart of the halo effect. If a soldier made a good (or bad) first impression on his...

Halo Effect

... The Halo effect Mr. Yegrrrrn Dennohrr Sasha College 24/05/2014 The halo effect The phenomenon which occurs when an individual judges a person and decides on his likability based on his specific traits. The occurrence of the halo effect is best described in an instance where a movie star or a musician often portrayed not only as being attractive but also likable. An so based on these qualities, most individuals tend to think that they also are friendly, cheerful, have a good personality and so on and so forth. (Thorndike, 1920, p. 25-29). In trying to find an explanation to this phenomenon, theorists identified the socio-cultural theory which plays a major role in explaining this phenomenon. The socio-cultural theory provides an explanation on how social interaction and cultural interaction affects what the mind perceives. It is clear that the mind plays a very important role in the halo effect since it is the one that determines likability. (Efran, 1974, p. 45–54) In this document, in-depth discussions on halo effect are going to be looked into, from the writers opinion, the concept of the halo effect can be generally categorized under the attribute of likability. In other words people make judgments based on the qualities one is attracted to for example people like people who are intelligent, skillful, attractive, among others. Basically it is all about likability of a person, a product or a service. Some of the personal experiences on the halo effect are discussed......

Medication Error

...process in improving patient care and safety during hospitalization. Medication-related errors are serious and occur at a rate of about one per patient per day (Allan, 1990). It is a harmful practice affecting patient’s health and life. Some of these errors may result in death or inefficiency of organs functions. In addition, medication errors may financially affect the health care organization due to long patient stay in the hospital for advanced treatment (Presto, 2004). This research paper will provide highlights on medication errors definition, importance of safety during medication process, factors contributing to medication errors and effective factors in preventing medication errors. Medication errors were defined as a fault in medication that may occur at any stage of the process in ordering or delivering medications (Bates, Boyle, Vliet, Scheider & Leape, 1995), either an injury occurred or the potential for injury was present (Bates et al, 1999). These errors could occur in dosing error, which is common (Lesar, Briceland & Stein, 1997), or wrong route, or wrong time, or error in medicine rate and omission error (O’Shea, 1998). Also there are some situations such as missing a dose of medication or the correct medication given too many times to the patient. Both of these situations are considered as medication error (Bates, Boyle, Vliet, Schneider & Leape, 1995). These errors can happen anywhere, it can occur at home, pharmacies and hospitals or doctor’s......

Accounting Errors

...The Accounting Errors of Overstock.com In 2008, the companyOverstock.com (NASDAQ: OSTK) received some publicity when they made decisions that violate the Generally Accepted Accounting Principles (GAAP). Their internal accounting policies and their relationship with external auditors caused the company to have to restate their financial statements dating back to 2003. Overstock.com improperly took income that it earned but under-billed its fulfillment partners during earlier reporting periods (Q3 2008 and earlier) and moved the income to future reporting periods (Q4 2008, Q1 2009, Q2 2009, and Q3 2009). Basically, Overstock.com took the income that they should have reported in earlier reporting periods (Q3 2008 and before) and moved it to future reporting periods (Q4 2008 and later). This action materially overstated their financial performance in later reporting periods. “Overstock.com admitted that they “incorrectly amortized the expense related to restricted stock units based on the actual three year vesting schedule rather than a three year straight line amortization and applied an outdated forfeiture rate in calculating its expense under the plans.” Accounting errors are not unusual for a business. When an accounting error occurs that is at the level of the error of Overstock.com, it is an indication that involves some high-level company officials may be involved.

Chances are you wouldn’t ask how the quarter is progressing or about last year’s earnings, but you would focus on the prospects for cash coming in versus cash going out over time. Sole proprietors understand intimately that the value of their business hinges on the cash flow the business generates. No distributable cash, no value. Cash puts food on the table and pays the mortgage; earnings do not. Equity investors are business buyers. While most shareholders own only a small fraction of a company, they are owners nonetheless.

Interview Errors

...Camille Alexandra G. Del Rosario Individual Assignment Interview Errors 1. Stereotyping: Stereotyping involves forming a generalized opinion about how people or the candidate of a given gender, religion, race, appearance, or other characteristic actually thinks, acts, responds, or would perform in a job without any evidence that it is actually true. Stereotyping is not only hurtful but is also wrong. It is not right to constantly put someone down based on your preconceived perceptions because this will not encourage them to succeed. One example of stereotyping is presuming that a woman would prefer a desk job over working outdoors because of her gender. Another example would be the applicants’ appearance that makes him/her seem unable to do the job. Also another is not hiring or promoting married women because they are not the primary earners of their family and will most likely focus on the family rather than the job. 2. Halo Effect: The "halo" effect follows when an interviewer allows one outstanding positive feature about the candidate to overshadow or have an effect on everything else. Employers tend to generalize one exceptional point of a candidate as representative of success even if it is unrelated to the traits and skills the employers are looking for. The Halo effect is a very subjective bias about a person that actually influences the total judgment of the interviewer. The halo effect also sometimes makes us attribute all sorts of......
