FEATURES OF AN Unit 2 InformationINFORMATION SYSTEM Systems
INFORMATION SYSTEMS Information Systems are in place to manage and support the day - to-day running of an organisation and its management There are several key elements that affect the systems that are in place: DATA PEOPLE HARDWARE SOFTWARE
DATA An information system is only as good as the data that is input Poor data will lead to poor results being output Incomplete or inaccurate information means output information will be incomplete or inaccurate There fore the system becomes useless For the data that is output to be accurate or complete the source data needs to be of good quality. Data is generated by all parts of an organisation Data can also be received from outside the organisation Sales orders
PEOPLE People are involved in the capture, processing and the inputting of data in a organisation. People can affect the quality of information and the information system because if the data to be input is captured in the wrong format or input incorrectly it can make the information become useless. This means that the system is only as good as the expert it has been collected from Training is important to get people who capture and input the data to work efficiently
SOFTWARE Software should be able to handle data quickly and efficiently, and that it can be easily searched though when needed. The simplest MIS can be built using run of the mill software. Most MIS’s use specialised software The cheaper the MIS = the less features it has. The more expensive the MIS = the more features it will have. The hardware and software need to work well together
HARDWARE The hardware should be flexible enough to cope with stress and strain put on it throughout the whole organisation. Should be able to store data in large volumes. In large organisations the MIS is normally run on a server so that the whole organisation can use it, however in smaller companies the system may be run on a stand alone computer in the directors office.
