John Harrison does not fit IBM’s Liquid crowd sourced software development

Posted by eggsearle on May 8, 2011

IBM have created a crowd sourcing software development model (Liquid) , described in this video

The example of John Harrison’s development of a chronometer to win the Longitude Prize  is given as an example and justification of Liquid.  Consider the following features of John Harrison’s work:

  • Prize amount of ~ $5 million dollars (equivalent)
  • 16 years from establishment of prize until Harrison draw up his initial proposal
  • 5 years to build first prototype marine clock
  • 5 years to build and test second prototype
  • 17 years to work on unsuccessful third prototype
  • 6 years to build prototype marine watch
  • Never received full award (which was never awarded to any person)
  • Had to petition  the King to receive even the partial award.
It is hard to how a successful software project could be modeled after the above history!
