Example notepad interface word interface mail manager network interface notepad interface mail manager network interface built-in editor mail manager network interface built-in editor database interface file storage database interface file storage Derive Product Derive Product Customer 1 Customer 2 Marco Sinnema, Sybren Deelstra and Piter Hoekstra, University of Groningen

5. Knowledge Externalization A system with a word interface requires more memory than one with a notepad interface. Our own editor consumes even more! Document Formalize Marco Sinnema, Sybren Deelstra and Piter Hoekstra, University of Groningen

6. Variability Modeling Most Variability Modeling Techniques COVAMOF Tacit Knowledge Documented Knowledge Formalized Knowledge Document Formalize Marco Sinnema, Sybren Deelstra and Piter Hoekstra, University of Groningen
