  2. Fredrick P. Brooks, Jr • One of the biggest GURU in IS • Still CS professor at UNC-chapel Hill • Ph.D. from Harvard (applied Math = CS) • Dissertation: The Analytic Design of Automatic Data Processing Systems • Manager for Development of System/360 Computer Systems (OS 360) • Introduced April 7, 1964 • Starting point of information age • Start to transform businesses using CBIS • NASA, insurance, airline, government…

  3. Comments • Paraphrase – use your own words… • Do not copy • Try to analyze…meaning try to borrow ideas from other fields (e.g., operations management, human resource management, marketing, finance, accounting, strategy…) • Find focus pages.. • Pages 5 and 6

  4. The Tar pit 1 • Large programming is like tar pit: • The more your struggle, the more you sink in it… • None of thing seems to be difficult, but as whole, the developers (programmers) get trapped in it and the project dies • You may be able to take one hand out of the tart pit, but not your whole body.

  5. The Tar pit 2 • A programming systems product must be: • Thoroughly tested (so dependable) • Not 100%...errors still be found… • Increase cost as much as 3 times over untested products • Officially documented • A system can be fixed and extended (blue print)

  6. The Tar pit 3 • Must work reasonably well with other programs • So, must be tested in all possible combinations… • I/O interfaces become very important • Cannot be tested with future system components • A programming system product as a system component costs at least 3 times higher than a stand-alone program (no interaction with other programs)… • Must be within allotted budget • Still almost impossible…almost never been possible……

  7. The Tar pit 4 • The joy of the craft • Why is programming fun?....what fun? • Only few people can enjoy…not me..not you.. • The woes of the craft • Mission impossible • No program can be 100% perfect….forever?? • Ultimate responsibility in business perspective • top management – CIO, IS director • Systems become obsolete
