  1. BUS1MIS Management Information Systems Semester 1, 2012 Week 1 Lecture 2

  2. MIS Basic Knowledge • What is an Information System (IS)? • How does a typical business operate in terms of paperwork and data flow?

  3. What is an IS? Terms you will need to be familiar with include: • Data capture • Data input • Data storage • Data processing • Data output • Attribution of meaning • Information • Decision making

  4. What is an IS? In this lecture we will investigate the nature of an IS by developing: • A model of a weather forecasting system • A generalisation of the model to fit other contexts In your tutorials we will apply the general model to business contexts Some reading to support the development of the weather forecasting IS can be found here: http://ironbark.bendigo.latrobe.edu.au/subjects/MISB/IS.html

  5. Weather Forecasting Does Information Technology produce this forecast?

  6. Weather Forecasting Can Information Technology produce these warnings?

  7. Weather Forecasting This is all the IT can produce – a predicted air pressure map

  8. Weather Forecasting To make sense of the predicted air pressure maps, to produce the weather forecast and to make decisions about warnings we need … People … with a little help from some IT. People are a key component of an information system

  9. A model of a typical Weather Forecasting Information System

  10. A model of a typical Information System

  11. So, what is a Management Information System? A system of managers in an organisation making decisions based on information obtained by attributing meaning to the output of IT embedded in the system. The IT captures, inputs, stores, selects, organises and outputs data.

  12. Business Reports A typical output of the IT component of an MIS is a business report. This report is selected, organised data. It is not information. The report does not become information until a person interprets the report in the business context (attribution of meaning).

  13. Attribution of meaning example A business manager views a report which shows that sales of a product have decreased by 15% in the previous quarter. The manager considers removing the product from the inventory but uses the internet to look up the performance of a competitor. Sales of the product have decreased by 30% The manager makes a decision to retain the product in the inventory and to improve product placement in retail outlets.
