  5. 5.  The “problem” that Watson project was commissioned to solve was “win at Jeopardy.” Ferrucci was not addressing a deficiency in a current system or process. He and his team were instead creating a “problem” or puzzle to solve. Second, this was a “green field” implementation. There weren’t any clues on how to break down “win at Jeopardy” in smaller process steps to define visible milestones and deliverables. Due to the nature of the game, requirements would need to be found by Watson in real-time based on the clue data.
  6. 6.  Watson was a non-traditional system which seek to go beyond the limits of traditional computing and software programs Hence, It needed to look for new innovation methods for system development to meet to desired goal It used several development approach simultaneously due to lack of any empirical evidence to suggest which SDLC process to adopt. The Watson project a hybrid of Rapid Prototyping, Incremental development approach in parallel
  7. 7.  The Watson system utilized a different approach to its methods of analyzing, referencing, and prioritizing user input. The Watson system used an approach that included  Parallelism  a wide rage of question analytic methods  confidence estimates  balancing the strictness applied to knowledge sources know as the DeepQA approach.  Using an approach know as “parallelism” this Watson would use a variety of external resources from varied resources to gather data and decompose the query and generate possible hypothetical answers.
  8. 8.  The project first of its kind on such a large scale, hence it required a new approach A more detailed project objective with key milestones and sub-processes should have been used to measure the progress for better planning The team used rapid prototyping very late. They could have been used this method zearly in the development project to gain insights into the system
