Information systems can either be a software suite or a team of individuals that work towards creating a more efficient work that are most likely inclined with an increase in output, in a manufacturing setting, and an increase in the quality of service in a customer-oriented setting. The type of information system that would be utilized should of course depend primarily on the type and nature of the business it will be used for.
It is usually important for information systems be modifiable so that it cold rightly fit into the needs of a specific company. With that in mind, it may be riskless to say that there is no such thing as a pre-made information system because at any point, there would be modifications that would be requested by buyers of these systems.
In case a client filed for an insurance number (we are pertaining to an insurance company here), say, a client filed for number 123465 instead of 123456, which would of course result into an error. One way to prevent this from happening is to employ additional human resources that would reinforce the type and specifics of the system being used. Computers’ abilities are limited and they do need humans to verify and check everything being processed. A specific type of information system called a transaction processing system (TPS) are usually the ones most optimized for these instances because they are reliable and they always come with rapid responses too.
If an applicant for a stock option plan filled out her employee number incorrectly, this should result into a problem but rest assured that this could be easily solved. With the right modifications in the information operating system being used, the employee could never initiate such errors. I think the best way to prevent these man-made errors from happening is to program the information system to deny incorrectly filled out forms so that it would not enter the system in the first place. The employee who incorrectly entered his data should receive an error message like one that says “Sorry, the employee number is incorrect. Please check your department number.” This way, the employee would immediately know her errors.
In case a student was able to log in to the company computer as soon as he knew the right telephone number to call, this could be a problem because important information is usually stored on company computers. To prevent this from happening, installing a security feature using an updated management information system could be a good option. Such systems are commonly used to pinpoint individuals who could have permission a certain area or department of files that the system has control over. Using departmentalized passwords and an additional feature, master password could be a golden option too and it is generally safer to use these.
If ever a set of say, 87 receivable checks was sent to the computer center for processing and only 86 arrived because one was dropped along the way, this is a serious dilemma too because checks are most likely money-related and you know how important money is for a company right? Unfortunately, no computer and gadget could save companies from these errors because these are man-made. Being organized and responsible is likely the key here. Measure like putting the documents inside boxes with lock could be a good measure although more practical ways are available for a company with creative minded employees.
