Purpose

• Issue
• Clarify the needs between prime and contractors
• Establish a link between the users needs and the
  technical requirements
• Automatic correction/rewording to let the experts
  spend more time on deeper technical analysis.
• Methods Voice/video capture, lexical analysis
  of specification, resctricted dictionary,
• Example of industrial applications
• Airbus improve the efficiency of the Customer
  Focus Groups
• Space formalise the users need coming from
  outside the space domain (definition of a
  scientific mission, )
• The aim is to define future development in the
  fields of
• Requirements Capture Translation of needs
  expressed in natural language into
  well-formulated requirements.
• Requirements Analysis Completeness,
  consistency, ambiguities, unicity, value anaysis
  (priority, criticality, weight, )

The needs and expectations

• The needs from industrial companies mainly deal
  with
• The capture method based on voice processing,
  this activity is dedicated to the oral capture
  and the formulation of users needs.
• The requirements analysis based on linguistic
  approach and starting from a requirements
  document, the expected results are
• The detection of ambiguities, inconsistencies,
  etc. and corrections to meet verifiable
  requirements.
• The assesment of the quality of requirements
• A guideline to better formulate requirements
• The processing of Requirements Database based
  on modelling techniques (UML, ) the goal is to
  identify reusable products associated to a set of
  requirements
• Expected results
• A demonstrator of voice-based requirements
  capture tool.
• A demonstrator of a natural-language-based
  requirements analysis tool.
• A Data Model devoted to requirements reuse. This
  model shall be implemented in a commercial tool
  to support automatic generation of pieces of
  design.

Conclusion

• The subject has been split to distinguish
• Human sciences
• Linguistic
• Modeling
• These subjects are closely linked and may be
  merged differently
• First subject is more innovative
• Second subject is realist and guarantees the best
  Return on Investment.
• Third subject allows quickest results.
• We are still collecting inputs from potential
  users and we are missing sponsors for the
  project.
