REVIEW QUESTIONS: OUTCOME 2 Unit 4 Outcome 2 On completion of this unit the student should be able to formulate and justify strategies for developing, implementing and evaluating a networked information system in response to a social, economic or technological impetus for change 2.1 How information systems can be used to help achieve organisational goals See also Review Questions Outcome 3, 3.1 Questions 1 to 6 (RQuest_OC3.doc) in the January 2003 update for questions related to this key knowledge point. Question 1 Explain the difference between ‘internal information’ and ‘external information’ in terms of who receives it and their relationship to the organisation. [49] • Internal information is produced within an organisation for employees and for internal purposes. • External information is produced outside an organisation for outside users such as members, customers, client’s suppliers, shareholders and the public. Question 2 List four purposes of information. For each purpose, describe one kind of information that would serve that purpose. [50] • Inform: A Newsletter with the company’s AGM report informs shareholders about the company’s financial performance for the year. • Persuade: An Advertisement handout persuades customers to purchase new products and services. • Educate: A brochure is used to educate parents about helping children to handle bullying. • Entertain: A video showing the years highlights at the Noosa football club will entertain players and those involve. Question 3 Which of the following is an example of a tactical decision? A. How should we promote our new product? B. Should we approve this staff member’s leave? C. What kind of product line should we develop? D. Where should we hold the next staff Christmas party? [46-48] Question 4 The customer receipt from a supermarket checkout register is an example of A. detailed information. B. sampled information. C. exception information. D. summarised information. [50-52] Question 5 List four organisational levels. For each level state the type of information people at that level typically needed and the time frame they tend to operate in. [50-51] Question 6 a List five ways in which information can be structured. Explain the difference between each. Indicate which level(s) in an organisation is likely to make use of it. • Detailed information- For day to day activities. Can be very comprehensive and lengthy, used at the operational level of an organisation. • Summarised information- The main information. A summary of a detailed lengthy report. Used at middle and senior management levels for quick examining. • Exceptional information- Highlights situation that are outside normal, shows records higher or lower than expected. Sometimes requires immediate decisions or actions by middle and senior management. • Sampled information- A small part of the total information that can be generated on a particular subject. Market research reports etc. • Aggregated information- Information about everything on a particular subject. Very detailed. [50-51] Question 7 Describe how each level in an organisation makes use of information. Refer to the type of information they use and its structure. Briefly explain why each level needs a different ‘mix’ of information types and structures. [53-54] Senior Management- Use summarised and sample information to predict trends, set objectives etc. Exception reports highlight out of normal circumstances, senior management can then make corrective decisions. Middle management- carries out planning tasks such as training programs etc. Require summarised information in weekly, monthly, annual reports. Use exception reports to see if items are above or below what was expected. Operational management- rely on detailed current information to control day to day operations relating to specific departments. Non management workers- Workers at operational level need detailed information to perform their work tasks. Eg. To operate a new factory machine, the worker will need to read detailed instructions. Question 8 List six different types of information systems. For each: State their primary purpose. Identify which level in an organisation is likely to make use of such a system. In terms of the information produced, briefly explain why the level(s) you have identified would use the system. [228-233] Transaction Processing Systems- Processes data generated by an organisations day to day operational activities. eg Reservation for a grand final seat, Bank deposit, invoices. Office Automation systems- Process and manage documents through applications such as ‘word’ ‘excel’ and ‘publisher’. Management information systems- Produces structured summarised and exception reports for middle and senior management. Manipulates data from the transaction processing system. Executive information systems- Supports the work of senior management by producing highly summarised information needed to solve unstructured problems. Decision support systems- used to analyse data and solve semi-structured problems. Models allowing ‘what if’ alternatives can be examined by changing variables within the system. Assists middle and senior managements to make decisions by summarising or comparing data information. Expert systems- Combines the knowledge of human experts into a computer program that stimulates aspects of human reasoning and decision making. They can be used to double check an experts decision. Question 9 Describe three ways in which an organisation can benefit from the use of a networked information system. [249] • Sharing resources- data, printers, software. • To serve as a communications medium • To increase overall reliability, by providing a degree of redundancy- if one computer breaks down, others remain operational. 2.2 Types of networks and data communications systems and their specifications Question 1 The largest geographical area a Local Area Network could cover is A. a continent. B. a university campus. C. the state of Victoria. D. one floor of an office building. [249] Question 2 What do the letters WAN stand for? Contrast a WAN with a LAN. • Wide area network.- covers a wide geographical area using communication channels such as telephone lines, microwaves and satellites. Oposed to LAN local area network, covers a local area. [249-251] Question 3 a An organisation has four desktop computers and a laser printer. The printer is connected to one of the computers. Explain why the organisation could use a peer-to-peer LAN with few difficulties. • Because peer to peer networks are good for small workstations. b An organisation has fifteen desktop computers, three laser printers and a scanner. Explain why it should not consider a peer-to-peer network. • Because this heavy traffic will slow the network down considerably. [250-251] Question 4 The term ‘bandwidth’ refers to A. the data transfer capacity of a data transmission medium. B. the width of the cable used as a data transmission medium. C. the rate of data transfer through a data transmission medium.
