Output – outputs can be in two formats, graphical and textual. A graphical output is used for seeing the bigger picture, usually presented as charts, diagrams or pictures. Textual is used when data needs to be analysed in detail; it’s often presented in text and numbers.
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. In an open loop system there is more flexibility on what the user can report on and the format in which the information is outputted.
I suggest the business ensures that their information is relevant and up to date. Relevant information is information that is specifically related to your business needs. If a business was looking to cut costs they might look at their electricity bill and try to see where they could save money; this would be relevant information as they can use it to reduce their costs. A good way of ensuring relevance is to closely outline the objectives of any information reports.
Up-to-date information is information that is related to the time the business is operating in. For example, a manager will need daily information on how their stores are performing, which products are selling well or not well so that they can come up with strategies to improve the performance and become more profitable. 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.
