3 3 Hoofdstuk 3: Bedrijfsaspecten van ICT Effectiviteit, Efficiëntie, Flexibiliteit en Productiviteit van informatiesystemen en het omgaan met informatie

4 4 Soorten Informatiesystemen Volgens niveau van leidinggeven Volgens functioneel gebied

5 5 De belangrijkste soorten IS

6 6 Additionele types IS Office Automation Systems (OAS) Knowledge Work Systems (KWS) (Source: Laudon & Laudon, Management Information Systems 8, chapter 2)

7 7 ERP Systems Enterprise Resource Planning (ERP) systems:

8 8 Capital management (IT investment decisions) Foundation of doing business (high-quality, low-cost) Productivity (increase productivity and efficiency ) Strategic opportunity and advantage Value of Information Systems Reasons why IT matters to the business:

9 9 Create competitive advantage: IT makes it possible to develop competitive advantages. New Business Models: Dell Computer: IT enabled build-to-order business model. Create new services: eBay has developed the largest auction trading platform for millions of individuals and businesses. Differentiate yourself from your competitors: Amazon has become the largest book retailer in the United States on the strength of its huge online inventory and recommender system. Strategic Opportunity and Advantage

10 10 Four Kinds of Structural Change: Automation: Mechanizing procedures to speed up the performance of existing tasks Rationalization of procedures: The streamlining of standard operating procedures Business process reengineering: Analysis and redesign of business processes to reorganize workflows and reduce waste and repetitive tasks Paradigm shift: Radical reconceptualization of the nature of the business and the nature of the organization Information Systems and Organizational Change

11 11 Figure 14-3 Organizational Change: risks and rewards

12 12 Cost of Information Systems Total cost of ownership includes: Hardware Software Installation Integration Training Support Maintenance Infrastructure requirements Downtime Space and energy End-user cost (time, fuzz-factor)

13 13 THE INTRANET: COST ASPECTS

14 14 Maintenance 67% Integration 8% Module testing 7% Module coding 5% Design 6% Planning 1% Specification (Analysis) 4% Requirements 2% Relative costs of lifecycle phases

15 15 Informatie en bedrijfsvoering: aandachtspunten!! Operationele systemen Verlopen de operaties efficiënt, flexibel? Bruikbaarheid, aanvaarding Is voldaan aan de regels? Knowledge Work systemen Worden de werkzaamheden ondersteund? Information & Knowledge management Ondersteuning van managementbeslissingen Is de informatie voorhanden? Hoe kunnen betere beslissingen genomen worden? Algemeen ook: kosten en baten, TCO

16 16 Information systems literacy: Broad-based understanding of information systems that includes behavioral knowledge about organizations, management and individuals using information systems as well as technical knowledge about computers Computer literacy: Knowledge about information technology, focusing on understanding how computer technologies work

17 17 Information Systems Problem Areas

18 18 Information Systems Success or Failure Factors Figure 15-5 Causes of Implementation Success and Failure

19 19 Een aantal voorbeelden Information overload Informatie-integratie Kwaliteit van informatieverwerking De totale keten Kwaliteit van het proces Effectiviteit en efficiëntie

20 20 Data explosion problem Automated data collection tools and mature database technology lead to tremendous amounts of data stored in databases (legacy data, ERP, scanner data, web data, documents, mobile, multimedia, RFID, …) Traditional techniques Paper, Query and reporting, Spreadsheet analysis, … But: information overload The Information Tsunami Who wants some more data?

21 21 Megabyte: 1,000,000 or 10 6 bytes 2 megabytes: Hi-res photo 5 megabytes: Complete works of Shakespeare Gigabyte: 1,000,000,000 or 10 9 bytes 1 gigabyte: Pickup truck filled with paper 2 gigabytes: Movie on a DVD Terabyte [ 1,000,000,000,000 bytes OR bytes] all the X-ray films in a large technological hospital 2 Terabytes: An academic research library 10 Terabytes: The printed collection of the US Library of Congress 50 Terabytes: The contents of a large Mass Storage System 200 Terabytes: Worldwide production of office documents (printer/copier) 400 million trees (annually) 900 Terabytes: The required storage space for (annual) Petabyte [ 1,000,000,000,000,000 bytes OR bytes] 1 Petabyte: 3 years of EOS data (2001) 2 Petabytes: All US academic research libraries 8 Petabytes: All information available on the Web 20 Petabytes: Production of hard-disk drives in Petabytes: All printed material Exabyte [ 1,000,000,000,000,000,000 bytes OR bytes] 2 Exabytes: Total volume of information generated worldwide annually 5 Exabytes: All words ever spoken by human beings Zettabyte [ 1,000,000,000,000,000,000,000 bytes OR bytes] Yottabyte [ 1,000,000,000,000,000,000,000,000 bytes OR bytes] The Information Tsunami (www.sims.berkeley.edu/research/projects/how-much-info-2003/)

22 22 Structured/Unstructured Information

23 23 Growth Trends Moore’s law Computer speed doubles every 18 months Stored data total storage doubles every 9 months Consequence very little data will ever be looked at by a human More intelligent use is NEEDED to make sense and use of data. (Gregory Piatetsky-Shapiro) Storage Processing

24 24 Today’s Information Systems: Islands of Information Order Entry Training Schedules CRM Web Content Knowledge Base Departmental Silos of Information ERP Product Literature Support (P. Hinssen)

25 25 Portals Order Entry Support Training Schedules Product Literature ERP Web Content CRM Knowledge Base Enterprise Portal Everything you need to do your job Sales Marketing Customer Service etc. Customers Partners Suppliers Extranet Portal One-to-One relationships (P. Hinssen)

26 26 Knowledge work systems A recent Slashdot posting reports that, according to both PricewaterhouseCoopers and KPMG, more than 90% of corporate spreadsheets contain material errors. With each error costing between $10K and 100K per month, one expert estimates corporate America loses in excess of $10B annually through the misuse and abuse of spreadsheets.Slashdot posting

32 32 Symptoms: Volume Time Broadcasts Lost Knowledge Spam Attachments Viruses Security The real problems: Content management Expertise Document management Routing Workflow Attitude … Spam is a problem, a big problem, but the solution is easy: Delete. The real problem is the rest of the s

33 33 Advantages of Fast Inexpensive Electronic, Stored, provides a record Independent of time and place Great for sharing and distributing documents Can eliminate telephone tag Reduces hierarchy Supports collaboration Supports virtual teams and teleworking Has changed the way we do business!! Advantages for the sender, or the receiver?

34 34 The Dark side Growing at 40% each year 30 messages per day in 2007 is 82 messages per day in 2010 Cost of time wasted is huge Often 3 to 4 hours per day spent on without any offsetting reductions in other work Taking over our lives 40% of people take computers on vacation with them to avoid backlog when they return to their offices is upsetting both organizations and people The cost of time wasted by poor habits is estimated to be $20+ million per year in an organization of 10,000 employees Much, perhaps most, of the we receive each day is just time-wasting, mind-numbing noise
