(5) Redesigning with information systems See Chapter 12 of Laudon & Laudon 7 th (Ch 10 in 7 th, Ch 11 in 6 th) l l My take is that it’s a bit “new technology” based You don’t need the latest fashionable systems to transform a business – » get understanding of costs and sources of funding » rationalize processes to manage costs and profitability l Can go on to re-engineer fundamental processes BS 3909 Week 12 7
(6) IS Project Management l l See also Chapter 13 of Laudon & Laudon 8 th edition Too many disasters to count » Projects not properly defined (or definition changed) » Inadequate user buy-in » Underestimates of scale of project l l l PRINCE introduced to help manage these aspects Need to Quantify objectives, and. . Control risks, progress, costs and quality Cost, duration, function and quality are interrelated » Change one and the others will be impacted » It’s better to cut function than to cut quality BS 3909 Week 12 8
(7) e-Commerce and e-Business l l See Chapter 9 of Laudon & Laudon 8 th and 7 th eds e-Commerce – Main focus is communication between business and outside » B 2 C: Business to Consumer » B 2 B: Business to Business » Different technological demands, but both depend on wide-area networking » Concerned with supply chain (up- and down-stream) Explain the main differences l e-Business – adds use of IS for internal processes » Typified by Enterprise Resource Planning systems BS 3909 Week 12 9
(8) IS Security and Control l Chapter 14 in Laudon & Laudon (7 th and 8 th editions) Business exposures What are threats? » Security breaches » System failure l Defence mechanisms » Encryption and authentication » Back-up and Recovery » Disaster fall-back l l Safety-critical systems Legal responsibilities BS 3909 Week 12 10
(9) Ethical and Social Impact of IS l l l Moral risks inherent in Information Systems Risks caused by unethical behaviour – from viruses and worms to improper synthesis of personal data Legal controls » » l l l Data Protection Acts Computer Misuse Act Credit information laws in UK and USA Human Rights Act Intellectual Property Rights Risks to Health and Wellbeing “Ethical Organizations” BS 3909 Week 12 Laudon and Laudon Ch. 15 11
(10) Managing Knowledge l l See Chapter 10 of Laudon & Laudon 8 th (Ch 12 in 7 th) Concept of Data => Information => Knowledge » Need to manage explicit and tacit knowledge l Information supply is exploding » Articles published – Journals > 360, 000/year by 2000 » Gartner Group predicted that knowledge management will become a $2 billion market by 2004 l Knowledge management market borders on » data-mining (mainly in transactional/financial data) » search tools (finding what you know to be there) l With additional goal of capturing understanding BS 3909 Week 12 12
Knowledge Management Systems l Include many simple and prosaic applications » Calendars, Groupware, Document imaging » Re-use of existing knowledge in new contexts l . . and more complex » Workflow systems to capture knowledge of processes » Systems to capture and codify knowledge l Cannot be restricted to the precise » Traditional IS domain is exact measurements » Knowledge requires balancing and weighting inputs » Logic required is often “fuzzy” l Artificial Intelligence and Expert systems BS 3909 Week 12 13
IBM: An International Business l Started in USA with machine for 1890 census » » l Applied “punch card” technology to Business Introduced automated time-clocks 1914: “International Business Machines” in Canada 1922: Whole corporation renamed IBM, and started subsidiaries in most developed countries Specialized in precision electro-mechanical products: » Butcher-scales, time-clocks, card sorters and collators » Bought electric typewriter company in 1930 s » Biggest manufacturer of gears in the world by 1945 l US Government took action in 1950 s to limit IBM’s control of punch-card business BS 3909 Week 12 14
What about Computers? l IBM sponsored Columbia University to produce high-speed number-crunchers in 1940 s » NOT a stored-program computer (Britain did that first!) » Main US developer of computers was Univac l Around 1955, IBM was brave (and lucky) » Decided to invest in computer development » Invented magnetic disk drive » Sperry bought Univac and slowed investment l Set up laboratory in UK in 1957 » Britain was at leading-edge of scientific computing l Introduced “Systems Engineers” to develop market BS 3909 Week 12 15
1960 s l Computing had become international » National markets still relatively small » Need larger market to write-off development costs » IBM & other US companies could use existing channels l IBM sued by CDC over 7030 “paper machine” » Consent decree forbade “pre-announcement” l IBM Hursley invented ROM (Read-only memory) » Behaviour of hardware determined by programming » Allowed first “family” to be developed: System/360 l $25 M programming project to produce OS/360 » Raised cost of entry to computer business BS 3909 Week 12 16
Impact of System/360 l Revolutionized computing » One “family” for scientific and commercial computing » Scalable – programs would run on whole range » Concerns arose about US domination of market l IBM set up manufacturing and development sites » » » Goal was to spend income made in each country Plants in UK, F, NL, D, S, I, CDN, J Development labs in UK, F, D, NL, CH, CDN, J Other international functions in UK, B, IRL, DNK, A, E Corporation funded development (USA pays world) Took royalties on all Intellectual property (vice versa) BS 3909 Week 12 17
International Structure l Marketing and Manufacture managed by region » “Domestic” (US) operations » “World Trade” initial dealt with the rest of the world – then AFE (Americas/Far East) + Europe ME Africa – then AFE split into Latin America, Canada and FE – EMEA largely decentralized now l Development remained Corporate responsibility » Divisions handled particular product lines, e. g. – Small mainframes in UK, D, CDN and Endicott NY – Big mainframes based in Poughkeepsie NY – Research in Yorktown NY, Almaden CA, Zurich CH » Strong interdependence between laboratories BS 3909 Week 12 18
Strong Control allowed Brave Decisions l Mid-50 s – switched from punched-card equipment to electronic computers » IBM was dominant in punched card, not in computers l 1971 – ditched magnetic memory in favour of chips » IBM was most efficient producer of magnetic cores (competitors all licensed the IBM patents) l Pre-emptive strikes against technology substitution l Alas, didn’t do the same in the 80 s » PC developed on a shoestring » Not integrated into Corporate strategy » Underestimated competence of Microsoft BS 3909 Week 12 19
Parallel Sysplex Development l The problem » Mainframe technology (ECL) fast, but hot and costly » Not competitive with PC technology (CMOS) l The solution » Build collections of CMOS chips working in parallel » Find some way to make them run existing applications l Logistics » » Boeblingen were brilliant at CMOS chips Poughkeepsie could integrate mainframes Hursley could make CICS efficient on new hardware Santa Teresa and Toronto could fix up the database BS 3909 Week 12 20
