Topic 2 - The value and importance of information
What is the importance of up to date, accurate and complete information?
In order for information to be useful it must be:
accurate, up-to-date, relevant, complete, understandable
The accuracy of information depends on the accuracy of the data. Incorrect data will lead to incorrect information...
G.I.G.O. = Garbage In Garbage Out
A lot of time and effort is spent in making sure that no incorrect data is input to a system.
Businesses and organisations make important decisions based on information. They also monitor their progress, and use information to target their resources in order to make the best use of them.
Example 1: Information obtained by market research being used to inform decision making e.g. supermarkets check on the speed of accuracy of till assistants and can then decide whether to reward or reprimand
Example 2: A shop analyses the performance of its POS terminal operators and warns operators who are too slow or make too many mistakes.
(Process) Targeting of Resources to Gain a Competitive Advantage/Can target reasoning and strategy making (resources) to gain advantage over competitors
Example 1:
Advertising and marketing a product should be aimed at people likely to buy it otherwise it is a waste of time and money. Information can tell an organisation how well it is doing compared to its competitors.
Company decides to spend money on advertising in Area B to promote a particular product. (‘… because they have noticed sluggish sales’ may qualify for spotting trends mark)
Example 2:
A manufacturer spends money developing a new product because they have seen a gap in the market. A company developed special sized shampoo bottles when airline companies limited the amount that could be taken into the cabin. Information about customers’ buying habits is valuable here and can lead to an organisation or company becoming more profitable. Information can tell an organisation how well it is doing compared to its competitors.
Information from research is used to identify gaps in a particular market which can then be filled by developing a new product.
Example: Businesses will not prosper if decisions are made based on information that is not up-to-date. Inappropriate decisions may be made if important information is missing. If information is not understandable by the people who make decisions, then it is useless.
Process: Spot Trends
Example: Analyse sales data and realise when something is out of fashion e.g. sales of tape recorders or if one region buys more of something than another.
Example - SCHOOL PUPIL DATA
A school’s administration system contains information about pupils. Personal details such as a pupil’s contact details, are stored as well as some very personal information such as ethnicity, religion and medical information that the school might need. It is important these details are kept up-to-date because
Schools get funded on the number of pupils according to year, location, SEN, etc, if out of date or inaccurate information they will get the wrong funding.
If contact details are out of date then letters to parents might not get to them / might need to contact parents in an emergency and will not be able to.
Pupil’s medical problems / personal situations might change and school needs the latest information to be able to deal with it properly.
Could give a false picture of the whole national school population if information is not kept up-to-date.
Comply with DPA. Headteacher / Governors responsibility.
Medical emergencies.
There are three main costs to an organisation and these can be categorised into
financial,
time
and human resources costs.
