For each of the following organisations, state one use it can make of ICT and give one benefit to the organisation of this use. The uses of ICT must be different in each case.
a) A newspaper
b) A supermarket
c) A travel company
d) The Police
Newspapers
- Valid point: A newspaper can be sent articles by email which saves time.
- Explained: Emailed articles can be sent from anywhere in the World and received instantly. Software can automatically check the articles for spelling and grammar and the valid article can be automatically entered into DTP software that create the newspaper. Therefore breaking stories can be easily added to latest editions providing up-to-the-minute news.
Supermarket
- Valid point: Stock can be controlled automatically thus saving time, cost of salaries and potential human error.
- Explain: By putting an unique bar code on every product item, when an item is taken to the checkout it can be quickly scanned, the checkout can automatically inform the stock database it is being sold and since the stock database knows how many remain, it can decide whether to re-order more stock. There is no need for human stock checks (thus reducing salary costs) and since supermarkets carry large amounts of stock, a human may find it difficult coping with it all and may make mistakes or miss something. A computer would not.
Travel company

The Police
