So many researches were done on human factors in spreadsheets. At the most basic level, human error research in many domains has measured the frequency of errors and error detection rates. In this report I have covered many of the human factors and mitigating approaches for them. ACCIDENTAL ERRORS:- Accidental errors are nothing but slips and mistakes occurred by carelessness, the typing errors are the best example. Even though regularly occurring, there is always a big chance corrected and highlighted quickly by the person who is making the error. Few people, anyway, will go untraced and may lead to wrong values in remaining other cells. It will be vital to mention that almost all of the errors explained under this type/ category will also be done knowingly or suddenly occurred with intent which is malicious. By observing very closely/ examining different kinds of accidental errors, this can be discovered that they will be again classified into couple of various groups. They will be errors committed by the developer and errors committed by the end user. DEVELOPER-COMMIITED ERRORS:- The above kind of errors is the errors committed by the developer who is working on the spreadsheet design. These kinds of errors are normally seen in the working section present in the model. They are classified into three different types namely alteration, omission and deletion. 1. Omissions are nothing but the things that are accidentally left remaining in the model/ design by the developer. Human factors studies have proved that on the fission types of errors especially are harmful, as they have less detection rates/ speed. It can be assumed a key factor/ variable is deleted from the spreadsheet design and therefore, a crucial relationship is q... ... middle of paper ... ...ong for every single question. Overconfidence started decrease after a series of actions. In a different study [Arkes, et al., 1987], subjects started losing their overconfidence after given response after 5 deceptive and difficult problems.Additionally, we are according to Kasper's [1996] an overview on DSS research which casually providing information is not good enough. Almost all overconfidence studies have been working on individuals. Anyway, Company bosses rely much upon one-to-one meetings. From which, we know if groups or individuals are critically overconfident. Inspired of focusing on most overconfident research conducted on individuals, there is a proof that overconfidence also happens in the group settings [Ono & Davis, 1988; Sniezek & Henry, 1989; Plous, 1995].Human Err, SSR: 2003.Reducing Overconfidence in Spreadsheet Development Dr. Raymond R.

In MOD’s excel workbook I have used many macros to create shortcuts to different sheets and also macros to perform various tasks. Overall using macros will speed up how fast the end user can use and navigate the sheet and also make it easier to use. I have also used auto-sum, this automatically entered in a certain formula that I had chosen. By using auto-sum I saved time by not having to enter in long formulas. I have also used an automated filter tool, this tool filters out any data that the user decides is unneeded, which will help the user as it does not show data that useless to them or is unneeded.
...er what career field you may enter. The data has to be collected properly without it being so time consuming ,and it’s not only the functions that was collected in chapter 9 but the concepts that the entire Microsoft excel workbook is teaching can impact ones career effectively in a positive way. Excel creates a way for individuals to be on top information that is highly needed, without excel calculating this data will then become time consuming and then inaccurate, be smart about it and know what is what when dealing with different types data that’s needed depending on your career. It doesn’t if you’re a teacher, doctor, contractor, musician, or any other profession out there. Collect data the smart way. Be your own boss, and know what it takes.
Different levels of confidence can influence their academic performance.
and I will be working form this. The spread sheet is reliable as it is
When an error occurs, the first step usually taken is to identify the individual that is responsible for the mistake. Frontline providers in health care, like nurses and doctors, are usually held accountable when a mistake occurs that affects patient safety and care. While this is the easiest step, it is not the most effective. "When human error is viewed as a cause rather than a consequence, it serves as a cloak for our ignorance. By serving as an end point rather than a starting point, it retards further understanding [1]." Factors outlined in Henriksen 's hierarchy, e.g. individual characteristics, the nature of the work, human-system interfaces, work environment, and management, need to be taken into account to identify the source of the
It is known that the advisee will be acting upon the advice for that purpose without independent inquiry
Mistakes are made by everyone whether it be because of confusion, lack of correct information, or just an accident. Mistakes are what make us human because we can't be perfect

If the error is detected during a later stage of software development, The developers will require to do a lot of reverse engineering processes which will be very frustrating and time consuming, the developers will have to review preceding steps and rework their deliverables and also might have to start from scratch. The later the software error is detected the more the number of people will be affected by it. This will in turn result to an increase in the cost required to communicate with the affected people and then fix the error. Thus, the cost for communicating the details of the defect, distributing and applying the software fixes and probably retain and convince the end users to use this particular software that has been sold to hundreds and thousands of customers will be too high. Once the goodwill and the brand value of the software is affected it is difficult to regain the customers trust. Ensuring early fixing of errors will save the developers
It is shocking to know that every year 98000 patients die from medical errors that can be prevented(Kohn, L. T., Corrigan, J. M., & Donaldson, M. S. (Eds.), 2000). Medical errors are not a new issue in our healthcare system; these have been around for a long time. Hospitals have been trying to improve quality care and patients safety by implementing different strategies to prevent and reduce medical errors for past thirty years. Medical errors are the third leading cause of death after heart disease and cancer in America (Allen, 2013). In addition medical errors are costing our healthcare system an estimated $735 billion to $980 billion (Andel, Davidow, Hollander, & Moreno, 2012).
The primary cause is of airplane accidents does at some stage contain an element of a person being unable to discharge his duties correctly and in an accurate manner. More than 53% accidents are the result of ignorance or faults by the pilot during flight. Other staff is responsible for about 8% accidents. The most obvious errors by pilot are made during the take off or landing on the runway. Additionally errors can occur during the maintenance of the airplane outside the plane, whereby a lack of thorough inspection and oversight can lead to complication during mid-flight. Fueling and loading of the plane also sometimes create problems (Shapiro, 2001).
Mistakes are actually a very influential part of a person’s upbringing in life. Mistakes shape a person’s character to make them who they are today. A mistake can teach someone many different life lessons that will better them as a person and make their lives more enjoyable. A person will commit a mistake usually when he or she is distracted. Distraction is the number one cause of mistakes in our world today. Many people are afraid of making mistakes, so they play it safe in life and don’t strive to achieve everything they are capable of achieving. This is a very bad thing. People should not be afraid of the potential mistakes there are to be made. Instead, they should focus more on the great lengths they could go in life by pursuing their goals. Mistakes will happen on life’s journeys,
Problems in every society usually derive from one specific thing. Miscommunication. How many times have you gotten in an argument or a disagreement with someone over what someone said, and then you later found out that that person meant something completely different from what was running through your head? How many times have you gotten off the phone with someone—someone important, --and wondered, what in the world were he or she talking about? I often get this feeling after class.
For as long as I can remember, my father has been inordinately protective of my sister, Beth, but I never knew why. The day I found out, was the day my family fell apart. You see, my father was running to be elected as the President of the United States. Out of all the things in this world, he cared the most about politics. Now obviously, with my father potentially being America’s next president, Secret Service agents practically shadowed my family. Personally, I kind of liked having my father be someone important. The presence of armed agents protecting me made me feel special. Beth, on the other hand, took a completely opposite point of view. She always went around saying how much it stunk having a Senator for a father, because of how he was never around. Now, with him taking a leap as great as running for president, Beth hardly spoke a word to him. Her avoidance of him may have temporarily allayed her anger, but she had no idea what she would eventually be getting herself into.
