15. Slide no : 15 ST3520 L1 MT Technology Versus Systems r There are no hard lines, but in general terms: r Information Technology is concerned what it is, i.e. with mechanics: î Hardware; î Software; î Storage technology; î Communications equipment. r Information Systems is concerned with what it does: î Operational-level systems; î Knowledge-level systems; î Management-level systems; î Strategic-level systems.

16. Slide no : 16 ST3520 L1 MT Information Systems r Operational-level systems: Information systems that monitor the elementary activities and transactions of the organization. r Knowledge-level systems: Information systems that support knowledge and data workers in an organization. r Management-level systems:Information systems that support the monitoring, controlling, decision-making, and administrative activities of middle managers. r Strategic-level systems: Information systems that support the long-range planning activities of senior management.

17. Slide no : 17 ST3520 L1 MT IT and IS in Business Today r IS/IT is fundamental to virtually all business, public and private today. r Many organisations could not now survive without IT: î Airlines; î Banks; î Utilities. r IT is moving goalposts: î ATMs and home banking; î Pay per view television; î Industries wiped out and new industries created. r Watch the hype?

18. Slide no : 18 ST3520 L1 MT What about your use of Computers?

19. Slide no : 19 ST3520 L1 MT How to Look Foolish... "I think there is a world market for maybe five computers.” Thomas Watson, Chairman of IBM, 1943. “We have one here at Cambridge; there is one in Manchester and there is probably a need for there to be one in Scotland as well, but that is about all.” Prediction made about computers in 1947 by Douglas Hartree, an English Mathematician. "Computers in the future may weigh no more than 1.5 tons.” Popular Mechanics, forecasting the relentless march of science, 1949.

20. Slide no : 20 ST3520 L1 MT How to Look Foolish... “ I have travelled the length and breadth of this country and talked with the best people, and I can assure you that data processing is a fad that won't last out the year.” The editor in charge of business books for Prentice Hall, 1957. “But what... is it good for?" Engineer at the Advanced Computing Systems Division of IBM, 1968, commenting on the microchip. “There is no reason anyone would want a computer in their home." Ken Olson, president, chairman and founder of Digital Equipment Corp., 1977. Moral: If you want to be proved wrong - make a prediction about IT.

21. Slide no : 21 ST3520 L1 MT Summary r IT/IS is a vast business. r Modern business is highly dependent on it at both managerial and operational levels. r The speed of change in technology shows no sign of slowing. r It is subject to all sorts of: î Hype; î Misleading predictions; î Fashions/Flavours of the month.
