Introduction

Transfer-Encoding: chunked ´╗┐Describe the features and functions of information systems and explain how an organisation could improve the quality of its business information Input ? input to information systems works in two ways. The first way is detailed data. This is sorted and processed and makes the basis of the output from the system. The second part is when the user tells the system what sort of analyses they want form the system. Storage ? Data should be stored at the most detailed level. IT departments will have to make sure to have backups of the data in case anything happens to the original copies. Processing - Processing is the method that turns data into information. ...read more.

Control and feedback loops - Control and feedback loop is what happens in a business as a result of the output of the information system. Closed and open systems ? a closed loop system is when the user has a choice about what information they want to report on. However they are limited to predefined output formats.

Conclusion

To improve the speed with which information is produced, businesses usually need to look at upgrading or replacing their information systems. Having data that isn?t up to date would mean the business won?t be able to use the information or it wouldn?t be relevant to use to help improve the performance of the business. Data also needs to be accurate. Good information will be sufficiently accurate. Accurate information helps a business make correct decisions. For example, if a sales department sent inaccurate sales figures to the finance department it may result in incorrect tax calculations and would put them into danger. If information needs to be extremely accurate, then more time needs to be allocated for it to be checked. This will help the business because they will be able to set targets and goals according to the data in which will help the business become more profitable. ...read more.
