Give an example of information from within the organisation that w ... ould be appropriate for the Chief Executive Officer (CEO) of a national supermarket chain, and information from within the organisation that would be inappropriate for the same person. Briefly explain why in both cases. Appropriateness is one of the characteristics of the information which means that information needs to be relevant to meet the specific requirements of the task in which the information is to be used. For example, in a national super market chain, the report of the purchased products, products that are ordered in case of unavailability and rate at which the products are sold are important to CEO in an appropriate format at the end of each month. However, customer information is inappropriate to the CEO. 2. The value of information is subjective and depends on a number of factors.

In capturing the information is important to identify the entities about which information is needed for example, customer, product and supplier. Secondly, defining the attributes of the entity for example, name of the customer or address of the customer. Thirdly, create a structured format in which to capture the information for example: an order form. Lastly, develop a procedure for capturing the information for example: when customer place an order, complete and order form and pass the form to the finance department. When an information has been captured, it has to be stored in such a way that the information can easily be located and retrieved when needed which comes under existence. Storing the information involves three stages. Firstly, define the categories to index information for example, all orders sent to suppliers can be in one file, whereas orders received can be in one file and orders that are not received are in separate files. Secondly, developing the procedure to store the information. For example, when the files are [Show More]
