3. The  origins...   •  Mass  Produced  So-ware   Components,  Doug  McIlroy   •  NATO  SoEware  Engineering   Conf.,  Garmisch,  Germany,   1968  
4. Griss  Model   None Code leverage Black box code reuse Managed workproducts Architecture reuse Systematic Domain- specific reuse Reduced Development time Reduced maintenance costs Broader coverage High reuse levels Reuse enabled business Investment, experience Benefit
5. Common Situation
8. So3ware  Process  –  cont.   •  Process  Model   – So3ware  Reuse   •  Why  a  new  process?    
9. The  roots....   •  On  the  Design  and  Development   of  Program  Families   Parnas,  D.L.;     IEEE  Transac7ons  on  So-ware   Engineering,   Vol.  02,    Issue  01,    March  1976,   pp.  1  -­‐  9     David Lorge Parnas
11. “A software product line is a set of software-intensive systems sharing a common, managed set of features that satisfy the specific needs of a particular market segment or mission and that are developed from a common set of core assets in a prescribed way. Paul Clements and Linda Northrop, 2002
12. Features  and  Feature  Model   •  Feature   –  An  end-­‐user-­‐visible  characterisFc  of  a  system   –  A  dis$nguishable  characteris$c  of  a  concept  that  is  relevant  to  some  stakeholder  of  the   concept   –  It  should  have  a  concise  and  descripFve  name   •  Elements   –  Feature  diagram   –  Feature  definiFons   –  ComposiFon  rules   –  RaFonale  for  features  
13. Example   Manual Car Mandatory Features Optional Feature Transmission Horsepower Ar-conditioning Automatic Alternative Features
