What is Convergence?
For the Q Software:
Same executable running on ALL tools (XAPQT & IQPT)

Why Convergence ?
Reduce / Eliminate redundant work Enable flexible support & development staffing Ensure customer quality Encourage cross-site credibility Prevent unfair yield practices Decrease cost of qualification
Increase speed of evolution (synergy)
( From a conversation in DIMO November 1998 - some things take time! )

History of End Of Line Testers
1994 HRAPQT Developed for Formula 1, Canvas, & Tiger Lines
1995 Unique code on each HRAPQT
1995 I-Blaster improvements leveraged to TIJ 2.5 color
1996 I-Blaster code leveraged to Hercules & Tarzan
1997 I-Blaster Ready for Production
1999 I-Blaster code leveraged to Tiger
2000 XAPQT on Tiger / IQPT on I-Blaster
2001 XAPQT on Lava / IQPT on Tarzan
2010 All testers running same code

Test12
How is Convergence Achieved ?
Deny variation is necessary– force one solution everywhere without exception
Support “controlled” variations – allow each solution to be “built” from a common
set of configurable building blocks
Convergence = Synergy

Test13
How is Convergence Kept?
Lockup the tools so that nothing can change
Allow anyone to initiate change in a “controlled” fashion
Convergence = Synergy

Test14
Controlled Change
Software changes must do nothing by default (i.e. a configuration file must be modified for the change to take effect)
Software changes must be tracked (i.e. a source control strategy is absolutely necessary)
All software changes must be tested (i.e official releases must be made available once tested)
