  1. 1. People and Computers in Commerce<br />A Spreadsheet Way of Knowledge<br />---------------------------<br />Steven Levy<br />Tasama Vatanaputi<br />
  2. 2. The Birth of Electronic Spreadsheet<br />Before 1979, Harvard MBA students used ledger sheets as spreadsheet.<br />In 1978, Dan Bricklinfound that it is a routine and time-consuming task of recalculation in case of fluctuations in figures.<br />In 1979, Dan Bricklinand Bob Frankston developed the first electronic spreadsheet program, VisiCalc.<br />Tasama Vatanaputi<br />
  3. 3. VisiCalc: Father of the Spreadsheet<br /> VisiCalc is the application that turned the Apple II into a serious business machine.<br /> http://gizmodo.com/5315670/visicalc-father-of-the-spreadsheet<br />Tasama Vatanaputi<br />
  4. 4. Saving time<br /> “An accountant who got a rush task sat down with his micro and his spreadsheet, finished it in an hour or two, and left it on his desk for two days. Then he Fed Ex-ed it to the client and got all sorts of accolades for working overtime.” <br />Ezra Gottheil<br />Tasama Vatanaputi<br />
  5. 5. Keeping track<br />Spreadsheets help businesses to be aware of things that has been overlooked.<br /> e.g. the capability of sorting things in order shows the worst salesman in a company.<br />“Executives no longer have to be satisfied with quarterly updates, for it is now an easy matter to compile monthly, weekly, even daily updates.”<br />Tasama Vatanaputi<br />
  6. 6. What-if factor<br />The ability to create scenarios, explore hypothetical development, try out different options.<br /> e.g. “He (Gottheil) was offering the computer different hypothetical developments, and it was feeding back to him their probable consequences.”<br />‘An Entrepreneurial Renaissance’<br />Tasama Vatanaputi<br />
  7. 7. Decentralization<br />Theodore Stein of the Connecticut Mutual said that before VisiCalc, the company centralised its computers services in data processing division. Usually, people were not satisfied with the information from DP.<br />Now, thanks to VisiCalc, people outside DP can do the calculations themselves.<br />No more concern for the bureaucracy.<br />Tasama Vatanaputi<br />
  8. 8. Over-necessity of numbers<br />“There’s an increasing demand for quantitative rather than qualitative justification for decisions.” Bob Frankston<br />Hard figures shape people’s opinion.<br /> “We shape our tools and thereafter our tools shape us.” Marshall McLuhan<br />Frankston also mentioned that two people with opposite views can finally have the same view in front of a spreadsheet.<br />Tasama Vatanaputi<br />
  9. 9. Intangible reality<br />For business, there are more factors in reality that can not be turned into formulas.<br /> e.g. Market trend, Consumer behavior, Stockholders’ pleasure or misery<br />Formulas in a spreadsheet program are only assumptions of the model-maker.<br />“A phantom business within the computer”<br />Tasama Vatanaputi<br />
  10. 10. Trap of design<br />The format of spreadsheets is a great convincer.<br />The electronic spreadsheets become more the art of persuasion than a tool for business analysis and productivity.<br />“With graphs, things take on greater weight” Allen Sneider<br />Tasama Vatanaputi<br />
  11. 11. Lastly<br /> Electronic spreadsheet program gave a huge impact on the way of business that Bricklin’s teachers at Harvard would never imagined.<br />&quot;I&apos;m not rich because I invented VisiCalc, but I feel that I&apos;ve made a change in the world. That&apos;s a satisfaction money can&apos;t buy.&quot; <br /> - Dan Bricklin<br />BUT do not let ‘formulas’ manipulate the relations between people.<br />Tasama Vatanaputi<br />
